What is in the box, with the numbers for the parts bin: Gasket set with crankshaft seals and intake valve seals - Kohler 25-755-37-S, 26 pieces Two standard connecting rods - Kohler 52-067-67-S Two standard piston ring sets - Kohler 52-108-09-S Quantities are for a complete twin. Two rods and two ring sets, not one of each. Fits KT17, KT19, M18, M20, MV16, MV18 and MV20. All seven are 3.125 inch bore engines, which is why one kit covers the lot. KT17, M18, MV16 and MV18 are identical in bore and stroke at 3.125 by 2.750, 42.18 cubic inches. KT19, M20 and MV20 share the same bore with a longer 3.062 stroke. Two things to check before ordering, and they are the two that cause almost every wrong order on this family. First, the rings are standard size. If the block has already been bored, they will not seal. Kohler service sizes here are true inch - .003, .010, .020 and .030 over - not millimeters. Anyone used to metric oversizes will expect millimeters here, and there are none on this engine. Measure the bore after machining and order to what you measure, not to what you asked the shop for. And note that .003 is a production size rather than a rebore step, so do not read the ladder as a sequence. Second, identify the piston rather than the engine tag. Kohler changed piston crown and ring-land design partway through production without changing the model designation, so two engines wearing the same badge can take different rings. Pull a piston and look at it. No pistons and no valves in this kit. Pistons, valves, valve springs, stem seals, lifters, camshaft and oil pump are not included.

Rings alone are 843806. On the oil filters: this engine takes one filter, so the second is there for the oil change after break in. 492932S is the short two and a quarter inch filter, the same envelope and the same 3\/4 by 16 thread as the filter the engine's own parts list calls for, and it crosses to the same aftermarket filters. Oversize: the only oversize Briggs offers on this engine is .020 over, piston 843823 with rings 843824. There is no .010 and no .030. Identifying your engine: Briggs encodes displacement in the first digits of the model number, so a model beginning 38 is a 38 cubic inch engine and a model beginning 35 is the 570cc 35 cubic inch engine on a 72mm bore, which takes different parts. Model families covered include 381447, 385777, 386447, 386777 and 38E347. Do not select by horsepower: 38 cubic inch was sold at 21 and 23 horsepower, the 35 at 18 and 20, and the ratings were revised over the years. One part number worth knowing: Briggs 844009 is a piston with the connecting rod already attached, which costs considerably more and is not what this kit supplies. Rebuild figures from the Briggs V twin specifications: valve lash 0.004 to 0.006 inch cold, cylinder head bolts 165 inch pounds, connecting rod 115 inch pounds, flywheel nut 125 foot pounds, ring end gap 0.008 to 0.016 inch, spark plug gap 0.030 inch. Prime the oil filter before fitting, turn the engine by hand before the first start, and fill the oil to the dipstick rather than to a published capacity.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOVERHAUL KIT FOR THE 627CC VANGUARD V TWIN AT STANDARD BORE - Two standard 75.5mm pistons with ring sets, replacing Briggs 843805, plus a complete gasket and seal set, two spark plugs, two oil filters, a fuel filter and a bottle of assembly lube. The 38 cubic inch Vanguard is 627cc, 75.5mm bore by 70mm stroke. This is the standard bore kit. If your block has been machined, the only oversize Briggs offers here is .020 over, piston 843823 with rings 843824 - there is no .010 and no .030.\u003c\/li\u003e\n\u003cli\u003eWHAT IS IN THE BOX, WITH THE NUMBERS - Two piston and ring assemblies, 843805, standard 75.5mm; rings alone are 843806. A complete gasket and seal set, head gasket included and cut for the 75.5mm bore. Two oil filters, 492932S - the engine takes one, so the second covers the oil change after break in. Fuel filter 493629S, also catalogued 691035. Two spark plugs, RC12YC type, Briggs 792015, gapped at 0.030 inch. A four ounce bottle of semi synthetic assembly lube.\u003c\/li\u003e\n\u003cli\u003eREAD THE MODEL NUMBER, NOT THE HORSEPOWER - Briggs puts the displacement in the first digits of the model number. A model beginning 38 is a 38 cubic inch engine, which is this one - 381447, 385777, 386447, 386777 and 38E347 among them. A model beginning 35 is the 570cc engine on a 72mm bore and takes other parts. Horsepower will not sort it: 38 cubic inch was sold at 21 and 23, the 35 at 18 and 20, and the ratings were revised over the years. The number is on the blower housing.\u003c\/li\u003e\n\u003cli\u003eONE PART NUMBER THAT CATCHES PEOPLE OUT - Briggs also lists 844009, which looks like a piston assembly and is a piston with the connecting rod already attached. It costs considerably more and it is not what this kit supplies. If your rods are good, 843805 is the part you want. If a rod is damaged, 844009 is a separate purchase. Check the rod bearing surfaces and the crank journals before you order either, because a kit like this assumes the bottom end is serviceable.\u003c\/li\u003e\n\u003cli\u003eFIGURES FOR THE REBUILD, FROM THE BRIGGS V TWIN SPECIFICATIONS - Valve lash 0.004 to 0.006 inch, set cold.

This kit is for a block that has already been machined to that oversize; if yours is still at the 77.00mm standard bore, order the standard kit instead. Contents: two 77.50mm pistons with matched ring sets, replacing Kohler 24 874 49-S, with rings replacing 24 108 25-S; a complete gasket and seal set replacing 24 755 107-S; both crankshaft seals; and a tube of crankcase sealant for the closure plate and oil pan joint. Not included: connecting rods, bearings, valves, camshaft or oil pump. There is no ring style to identify on this bore. The Style A and Style B distinction belongs to the 80mm and 83mm engines, where the top ring thickness changed; the 77mm family has no such split, and this kit supplies pistons and rings together as a matched set in any case. Fits CH18, CH20, CH22, CH620, CH621, CH640 and CH641, and the vertical shaft CV18, CV20, CV22, CV620, CV621, CV640 and CV641, all 624cc. One caution: the CH22 and CV22 are listed in both the 77mm and the 80mm sections of the same Kohler manual, so on a 22 measure the bore rather than relying on the model number. Identify the engine from the model and spec numbers on the blower housing decal. Before assembly, check ring end gap in the finished bore and side clearance in the piston groove, and make sure the cylinder has a honed rather than polished finish for the rings to seat against.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFOR A BLOCK ALREADY BORED .020 OVER - READ THIS FIRST - These pistons measure 77.50mm, which is Kohler's plus 0.50mm step and the size the trade calls .020 over. They will not go into a standard 77.00mm cylinder. If your block is still standard, or has not been measured yet, order the standard bore kit and come back to this page once the machine shop is finished. Take the old piston with you so the shop can bore to match the piston rather than to a nominal figure.\u003c\/li\u003e\n\u003cli\u003eWHAT IS IN THE BOX, WITH THE NUMBERS - Two 77.50mm pistons, each with its own ring set, replacing Kohler 24 874 49-S. The rings replace 24 108 25-S. Complete gasket and seal set replacing 24 755 107-S. Both crankshaft seals. One tube of crankcase sealant for the closure plate and oil pan joint. Not included: connecting rods, bearings, valves, camshaft or oil pump. Those numbers are worth keeping to hand, because they are what the parts counter will ask you for.\u003c\/li\u003e\n\u003cli\u003eNOTHING TO MEASURE ON THE OLD PISTON - The 77mm Kohler twins have no Style A and Style B split. That distinction belongs to the 80mm and 83mm engines, and it exists there because the top ring thickness changed. On this bore it does not, and since this kit supplies pistons and rings together as a matched set, the old rings are coming out anyway. The only measurement that matters here is the bore itself.\u003c\/li\u003e\n\u003cli\u003eFITS THE 77MM KOHLER TWINS - CH18, CH20, CH22, CH620, CH621, CH640 and CH641, and the vertical shaft CV18, CV20, CV22, CV620, CV621, CV640 and CV641. These are the 624cc engines. The CH22 and CV22 appear in both the 77mm and 80mm sections of the same Kohler manual, so on a 22 specifically, measure the bore rather than trusting the model number. Read the model and spec numbers off the blower housing decal; horsepower alone will not identify the bore.\u003c\/li\u003e\n\u003cli\u003eWHILE THE SHORT BLOCK IS OPEN - Check ring end gap in the bore each ring will run in and side clearance in the groove before anything goes together. Make sure the shop left a honed rather than polished finish, or the rings will take a long time to seat. Clean the closure plate and oil pan faces to bare metal before the sealant goes on and let it cure before adding oil. These are hydraulic lifter engines, so there is no lash to set.

Two connecting rods replacing 25 067 04-S. Two intake valves, 24 017 01-S. Two exhaust valves, 32 016 01-S, a number also catalogued as 24 016 01-S - the two are the same part, 32 016 01-S being the current one. The valves are supplied bare: no valve springs, retainers or keepers are included. Two intake valve stem seals, 25 032 14-S, also catalogued 24 032 05-S and 66 032 05-S. One per cylinder, which is a complete set for this engine: these Kohler twins carry a stem seal on the intake valve only. The intake stroke pulls a vacuum that will draw oil down the valve stem, which is what the seal is there to stop; the exhaust port is under pressure when the engine is running and runs without one. Do not fit a spare seal to an exhaust valve. A gasket set covering both cylinder heads, the Kohler head gasket kit for a single head being 24 841 01-S. Both crankshaft seals, which are different sizes: 25 032 06-S at the PTO end and 24 032 19-S at the flywheel end. One tube of high-torque RTV gasket maker for the crankcase joint. CHECK THE DISPLACEMENT BEFORE ORDERING. Kohler built the CH22, the CH620 and the CH640 in two different bores, and the engine model number alone will not tell you which one you have. 624cc is 77mm and is what this kit fits. 674cc is 80mm and takes different parts. 725cc is 83mm. The displacement is stamped on the engine nameplate; Kohler's service manual states that the 620 and 640 changed from 624cc to 674cc during production and that the nameplate is where to confirm it. If the nameplate has gone, measure the bore - 77.000 to 77.025mm on a new cylinder, 77.063mm being the wear limit. ENGINES COVERED at 624cc and 77mm: horizontal shaft CH18, CH20, CH22, CH620, CH621, CH640, CH641; vertical shaft CV18, CV20, CV22, CV620, CV621, CV640. These are four cycle OHV twin cylinder engines with cast iron liners in an aluminum block, rated between 18 and 22 horsepower depending on model and year. OVERSIZE. Kohler's oversizes on this engine are metric, not inch: plus 0.08mm, plus 0.25mm which is approximately .010 over, and plus 0.50mm which is approximately .020 over. This kit is standard bore. NOT INCLUDED. Valve springs, retainers and keepers; the cylinder heads, camshaft, crankshaft and oil pump. The kit assumes the bottom end is serviceable, so inspect the connecting rod journals and the crankcase sleeve bearings before ordering. REBUILD FIGURES from the Kohler service manual. Cylinder head bolts in two steps, 200 inch pounds then 370 inch pounds; head nuts 150 then 315. Connecting rod cap 200 inch pounds on the 8mm straight shank bolt. Flywheel screw 49 foot pounds. Closure plate fasteners 216 inch pounds. Ring end gap 0.25 to 0.45mm in a new bore. Piston to bore running clearance 0.039 to 0.082mm. Valve seat angle 45 degrees. Minimum valve lift 8.07mm. These engines run hydraulic lifters, so there is no valve lash adjustment to make. Check ring end gap in the bore each ring will actually run in, use a ring compressor, fit the circlips with the open end away from the ports, and turn the engine over by hand before the first start.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e77mm REBUILD KIT FOR THE 624cc COMMAND TWIN, WITH RODS AND VALVES - Two standard 77mm pistons with rings, pins and clips, two rods, four valves, both intake stem seals, a gasket set, both crank seals and RTV sealer.

Displacement is stamped on the engine nameplate, and Kohler's own service manual says to confirm it there, because the 620 and 640 changed from 624cc to 674cc partway through production.

Identify your carburetor before ordering. The Homelite Super XL family was produced over many years and was built with two different carburetors depending on the year, and only the C2 series is covered by this kit. A carburetor that will not hold an idle, floods on restart, leaks fuel or leans out once hot usually has a stiffened metering diaphragm and an inlet needle that no longer seals. Strip the carburetor completely, clean the passages, and fit every piece in the kit rather than replacing one part.

This is the one thing that matters on this kit. The Homelite Super XL family was built over a long run and came with two entirely different carburetors depending on the year. Look at the carburetor body: if it is stamped C2-20 or C2-M3A, this is your kit. If it carries an SDC casting number, you need a different kit and this one will not fit it.\u003c\/li\u003e\n\u003cli\u003eWHAT A KIT FIXES. A saw that will not hold an idle, floods on restart, leaks fuel, or runs fine cold then leans out hot is usually telling you the metering diaphragm has gone stiff and the inlet needle is not sealing. Both are in the kit. Ethanol fuel and a few years of sitting will do this to any diaphragm carburetor.\u003c\/li\u003e\n\u003cli\u003eDO THE WHOLE CARBURETOR. All eleven pieces are there for a reason and there is no point replacing one diaphragm while reusing a hardened gasket. Take it apart completely, clean the passages with carburetor cleaner and compressed air, fit every piece in the kit, and set the mixture screws to a starting position from your manual before you try to start it.\u003c\/li\u003e\n\u003cli\u003eWHILE YOU ARE IN THE FUEL SYSTEM. Replace the fuel line and the tank filter at the same time. Old fuel line on these saws cracks where it enters the tank and draws air, which produces exactly the same lean running symptoms as a bad carburetor and will have you chasing the problem after a fresh kit is fitted.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lil Red Barn","offers":[{"title":"Default Title","offer_id":68009614704794,"sku":"B6-FX7X-OQPB","price":12.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0397\/2346\/6909\/files\/41KWk0cDREL.jpg?v=1793382755"},{"product_id":"rebuild-kit-briggs-intek-31-series-16-18-hp-ohv-594437-796187-384127702921","title":"Rebuild Kit Briggs Intek 31 Series 16-18 HP OHV 594437 796187","description":"\u003cp\u003ePiston ring set 594437 and complete engine gasket set 796187 for the Briggs \u0026amp; Stratton 31-series Intek single-cylinder OHV engines, 16 to 18 HP, at the 90.5mm (3.563 inch) bore.

Both are real, current Briggs numbers for this engine family and they are separate parts rather than one superseding the other. If a dealer has specifically quoted you 792023, contact us before ordering. QUANTITY. A V twin needs two pistons and two of each valve. All of that is supplied, so one purchase does the whole engine rather than one cylinder. STANDARD BORE ONLY. The .020 oversize piston is 792072 and the matching ring set is 792073. Neither is in this kit. A standard piston in a machined cylinder will not seal and cannot be returned once fitted. IDENTIFYING YOUR ENGINE. These engines powered riding mowers, zero turns, lawn tractors and generators across many equipment makes, so the plate on the machine carries the equipment maker's number rather than the engine's. The model, type and code are stamped on the blower housing. BEFORE ASSEMBLY. Measure bore taper and out-of-round. Inspect valve guides and seats while the heads are off, since that is the work you do not want to repeat. Wash cylinders in hot soapy water after honing. Check ring end gap in the bore each ring will actually run in.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWHAT IS IN THE BOX - Two 793560 standard piston kits with rings, one per cylinder.
