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. Standard pistons for this bore are 52-874-11-S.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWHAT IS IN THE BOX, WITH THE PART NUMBERS - Gasket set with crankshaft seals and intake valve seals, Kohler 25-755-37-S, 26 pieces.

Replaces Kohler part number 52-559-01-S. That number superseded to 52-559-02 and then to the current 52-559-03-S, so a dealer may quote you either of the later numbers for the same application. FITMENT. Kohler lists this pump for the KT17 and KT19, and for the Magnum M18, M20, MV16, MV18 and MV20. M means horizontal crankshaft and MV means vertical. A NOTE ON THE MODEL NAMES. There is no Kohler K17 or K19. The K-series twins are the KT17, KT19 and KT21, and the T is part of the designation. A part offered as a K17 or K19 pump is labelled wrong. The model and spec numbers sit together on the blower housing decal. WHAT KIND OF PUMP THIS IS. Mechanical and lever-actuated, driven by the engine. It is not a vacuum or pulse pump run off crankcase pressure, which is what the small single cylinder engines of the same era often use. THE SINGLE CYLINDER ENGINES ARE DIFFERENT. The K161, K181 and M8 take one pump, and the K241 through K361 and M10 through M16 take another. This is the pump for the twins. M16 and MV16 are not the same engine and that is the easiest ordering mistake to make here. BEFORE YOU REPLACE THE PUMP. If there is gasoline in the crankcase oil, check the carburetor float and needle first. A float that has sunk or stuck holds the needle open and will fill the crankcase, and it is a more common cause than a split pump diaphragm. Kohler's own troubleshooting for these engines says to make sure fuel is reaching the carburetor and to check the lines and the pump for restrictions. WHY THEY FAIL. Ethanol in pump fuel hardens the diaphragm and the internal valves. The pattern is an engine that starts and runs for a few minutes, then starves as demand rises. A machine that has sat with fuel in the tank is the usual candidate.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMECHANICAL FUEL PUMP KIT FOR THE KOHLER TWINS - Replaces Kohler part number 52-559-01-S, which superseded first to 52-559-02 and then to 52-559-03-S. Kohler lists this pump for the KT17, KT19 and the Magnum M18, M20, MV16, MV18 and MV20.

Read the model off the blower housing decal along with the spec number.\u003c\/li\u003e\n\u003cli\u003eTHE SINGLE CYLINDER ENGINES TAKE A DIFFERENT PUMP - M8, and the K161 and K181, use one pump.

M16 and MV16 are not the same engine, and that single digit difference is the most common wrong order on this family.\u003c\/li\u003e\n\u003cli\u003eCHECK THE FLOAT BEFORE YOU BLAME THE PUMP - If you are finding gasoline in the crankcase oil, a stuck or sinking carburetor float holding the needle open is the more common cause on these engines, and it costs nothing to check. Kohler's own troubleshooting says to confirm fuel is reaching the carburetor and to check lines and pump for restrictions.\u003c\/li\u003e\n\u003cli\u003eETHANOL IS WHAT KILLS THESE - The diaphragm and the internal valves harden and break down on pump fuel, and the usual pattern is an engine that starts, runs a few minutes and dies as demand rises, or one that will not pull fuel uphill.

Kohler consolidated four earlier gasket sets - 52-755-10-S, 52-755-92-S, 52-755-93-S and 52-755-94-S - into this one number across a long production run.

M16 and MV16 are not the same engine, which is the easiest mistake to make on this family. CRANKSHAFT SEALS, AND WHY THEY MATTER. The kit includes crankshaft seals. A hardened seal draws air past it and leans the mixture out, and the symptom on these engines is an idle that will not come down or a motor that revs and hangs. That gets chased at the carburetor for a long time before anyone pressure tests the crankcase. If the engine is open far enough to need gaskets, the seals are worth doing at the same time.

Bore is 3.125 inch, 79.4mm. One set covers one cylinder, so a twin cylinder engine requires two sets. The larger engines in this family gain their displacement through a longer stroke rather than a larger bore, which is why a single ring set covers the whole range. This is the standard size set. If the cylinder has been bored oversize, order the matching .010, .020 or .030 set instead. Rings will cure oil consumption and blowby on a bore that is still round and within taper limits, but they will not seal against a scored or glazed cylinder, so measure before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFITS KOHLER KT17, KT19, M18, M20, MV16, MV18 AND MV20 twin cylinder engines.

This set is for a cylinder still at 79.4mm and within service limits. If the block has been bored, Kohler lists .010, .020 and .030 oversize sets and you need the one that matches your finished bore. Measure the bore before ordering rather than assuming the last person left it standard.\u003c\/li\u003e\n\u003cli\u003eWHEN RINGS ARE THE ANSWER, AND WHEN THEY ARE NOT.

The kit holds one set of breaker points, 47-150-03-S, one condenser, 52-147-01-S, and two RV17YC spark plugs, one for each cylinder: the three parts a breaker-point ignition needs at service time. Set the point gap at .020 inch with the points fully open on the cam lobe; a gap that is off moves the timing as well as the dwell, and that is where a rough-running twin is usually put right. Change the condenser with the points, because a weak condenser burns and pits new points within hours. Gap the plugs to the figure in your service manual and tighten them to the manual's torque. While the cover is off, look over the plug leads for cracks, the coil connections for corrosion and the point cover seal that keeps water and dirt off the points.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFITS KOHLER KT17 AND KT19 OPPOSED TWINS - One set of ignition points 47-150-03-S, one condenser 52-147-01-S and two RV17YC spark plugs, one per cylinder.
