Engine Sleeve w/ O-ring

Yanmar Tractor Engine Sleeve w/ O-rings

Sold Individually
90mm Bore

Fitment Note:
If installing on a YM2000 -> This will only fit the YM2000 with the 2TR20A and 2TR20AX engines. The 2TR20 had a different size (smaller) bore and this will not fit the 2TR20 engine. 

Shop Tip:
These sleeves come pre-honed and ready to use. Per Yanmar's instructions- Clean the exterior of the sleeve with brake cleaner or carb cleaner. Install new orings and then coat the o-ring area and the top exterior lips of the sleeve with oil based paint before re-installing. This helps seal those areas and prevent corrosion. Coat the inside of the sleeve with engine oil to prevent flash rusting during rebuild. 

We highly recommend using a Service Manual for this type of work.
