These are opposed twin engines. A complete engine needs two sets. Order both before you take it apart. WHICH RING SET YOUR ENGINE NEEDS - GO BY THE PISTON. Onan used two ring groove thicknesses on this one bore, and it is the piston that decides, not the model or the year: Piston casting 112-0277 - .058 inch grooves - ring set 113-0310 - THIS SET Castings 112-0163 and 112-0246 - .077 inch grooves - ring set 113-0314 Because 112-0264 is the only piston Onan still supplies, an engine rebuilt at any point in the last few decades is likely to be on the .058 grooves regardless of when it was built. That is why the piston is the check and the model number is not. THE COIN TEST. A penny measures close to .058 inch. If a penny fits the top two grooves, this is your set. NOT THE BF. The BF is 3-1\/8 inch bore. A BF that has been bored to 3-1\/4 inch and fitted with the current piston does take this set, but a standard BF does not.

Replaces Onan part number 110-3480. Two valves is one complete engine - one per cylinder.

The difference between a P216 and a P218 is stroke, not bore. The B-series is where people go wrong. B43 and B48 use exhaust valve 110-1955 and intake 110-2368, and the B-series exhaust stem measures around 0.341 inch against 0.278 inch here. They are not interchangeable and they are not close. While the head is off, look hard at the valve seats. These engines have a reputation for seat trouble, and Onan's own service manual calls for the seat insert to be replaced when it is loose in the head, cracked or severely pitted. A new valve dropped onto a failed seat will not seal and will not last. That is a machine shop job and it is better to find it now than after reassembly.

Replaces 110-3479. QUANTITY Two valves are supplied, which is one intake valve per cylinder. These are twin cylinder engines, so one purchase does the whole engine for the intake side. INTAKE ONLY These are intake valves. Exhaust valves are a separate part number and are not included here. The exhaust valve runs far hotter, is usually a different head diameter and often a different alloy, and the two are not interchangeable. If you are rebuilding the top end completely you will need exhaust valves as well. FITMENT. P216, P218 and P220, including the LX720 and LX770 versions of those engines. IDENTIFYING YOUR ENGINE. The model and spec number are on a tag or decal on the engine itself. The plate on the machine carries the equipment builder's own number, which does not cross to engine parts. WHY INTAKE VALVES FAIL ON THESE ENGINES Valve recession - the valve sinks into its seat over many hours and clearance closes up. You lose compression and the engine gets hard to start. Stem and guide wear - side play lets the valve sit crooked on the seat, so it stops sealing and can start to hang open. Carbon build up on the stem and the back of the head, which also holds the valve off its seat. In each case the symptom is usually one weak cylinder rather than two, so compare the two sides before you condemn both. FITTING Lap each valve to its own seat, one at a time, and look for a clean even contact band right round the face. Check guide clearance with the new valve fitted. A new valve in a worn guide will leak again before long. Check the seat width and recut if it has spread. Set valve clearance cold to the figure in your engine manual once the head is back on and torqued. Torque the head bolts evenly in stages rather than pulling one down at a time, or you will distort the head.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTWO INTAKE VALVES, ONE PER CYLINDER - These are twin cylinder engines, so two intake valves do the whole engine and two are supplied.

Read the model and spec number from the tag on the engine rather than going by the machine it sits in, because the machine tag carries the builder's own number and will not get you the right parts.\u003c\/li\u003e\n\u003cli\u003eINTAKE ONLY - INTAKE AND EXHAUST ARE NOT THE SAME VALVE - The exhaust valve on these engines runs hotter, is a different head diameter and often a different material. They are not interchangeable and fitting an intake valve in an exhaust seat will burn it out. If you have the head off and are not certain which is which, measure the head diameter before ordering.\u003c\/li\u003e\n\u003cli\u003eWHY THEY GO - Intake valves on these engines recede into the seat and lose clearance over time, or the stem wears in the guide and the valve starts to hang. Either way you get hard starting, a lumpy idle and lost compression on one cylinder. Check the clearance cold and compare one cylinder against the other, because a single bad valve is far more common than two.\u003c\/li\u003e\n\u003cli\u003eDO THE JOB PROPERLY WHILE THE HEAD IS OFF - Lap each new valve to its own seat and check you have an even contact band all the way round. Check the guides for side play with the new valve in place, because a new valve in a worn guide will not seal for long. Reset valve clearance to spec afterwards, and check the seat width while you are there.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lil Red Barn","offers":[{"title":"Default Title","offer_id":68009643278490,"sku":"VX-IKTB-4KUP","price":59.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0397\/2346\/6909\/files\/51YFxJErnsL.jpg?v=1793383128"},{"product_id":"onan-pistons-rings-010-oversize-b43-b48-p216-p218-112-0264-10-3e-atkq-owod","title":"Onan Pistons Rings .010 Oversize B43 B48 P216 P218 112-0264-10","description":"\u003cp\u003eTwo .010 Oversize Pistons with Chrome Rings for Onan B and P Series Twins This listing includes two .010 inch oversize pistons, each with a chrome ring set, one for each cylinder of the Onan twin.

Two seals per order, which is a complete set for one engine. These engines fit a stem seal to the intake valve only, one per cylinder, and the exhaust valves are designed to run without one. Also fits the later replacement engines OL16, OL18, OL20, LX720, LX770 and LX790. Does not fit the Onan B43, B43M, B48 or B48M, or the P224, all of which use a different seal. Hardened valve seals cause blue smoke on startup and after extended idling. Inspect the valve guides at the same time, because a worn guide allows the valve to rock and will quickly destroy a new seal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFITS ONAN P216, P218 AND P220 TWIN CYLINDER ENGINES, and the later replacement engines OL16, OL18, OL20, LX720, LX770 and LX790. Replaces Onan 509-0210, superseded to 509-0289.

The B43, B43M, B48 and B48M use a different intake valve seal, and so does the P224. Check the model tag before ordering.

Look at the valve guides, because a worn guide lets the valve rock and will chew up a new seal quickly.
