So I have purchased a new injector pump. Anyone have any advice or tips about the install? I'm especially concerned about how many shims to use. I have the two that came off w/the old pump plus the 5-pc. set from Hoye. Any way to predict how many to use? The thought of removing the pump multiple times to get it right is not very appealing.
Typically you will just use the same shims that you took off. That will almost always be very close and is probably where 90% of our customer stop. Then, if you want to really dial it in, you will need to go through Yanmar's timing procedure and add/remove shims as needed to get the timing perfect.
Thanks for that. Makes sense to me. I installed the pump yesterday. No problem with leaking at the shims. I haven't been able to stop leaks at all three fuel tube fittings at the top of the pump though. Guess I'll have to take them off and try to get them seated in better. The nuts are so close together that they're really hard to get tightened.
