Injection Pump Shim Set

Yanmar Tractor Injector Pump Shim Set

Includes:
5 Injection Pump Shims (enough for almost every pump)

Recommended Items:
Fuel Supply Hose (per foot)
Fuel Supply Hose Clamps (OEM Style)

Shop Notes:
You will really want to time the Injection pump after installing. The timing is adjusted by the number of shims under the pump (between the pump & engine). This varies at what point in the engine's rotation the fuel is pressurized. You can usually get the tractor to run by just using the same shims that were under your old pump but to get it to run correctly you will want to time it.
