It is back alive!! Installed the pump and checked flow before the PC mark, spot on flow stopped at PC. Smoky startup but cleared after warming. Wet stacked bad from all the problems. Had to swap the VR as that died due to low RPM or extensive cranking. Had a spare handy.

Got the problem identified. Pulled the IP and took the button out, #12 and pump housing stamped 12. Turned the face gear and the plunger isn't turning. Broken key again. I have a parts spare but no more. Going to put the hydraulic parts through ultrasonic cleaning. Then brand new fuel.

Thanks! My life has been a bit busy to take care of this generator..plus the owner keeps getting different FMVs for me to work on ;). I'm pretty adept at this style of injection system from M35A2 multifuel to Bosch VE pumps. My main problem is working nights 4 days a week, then adapting to...

I have tried multiple times. Take valve cover off. Roll engine until the PC mark and both valves closed on #1. Cam lobe next to IP cam should point down and out. I am pretty sure it is the drive key. So once more, pull the pump and take it apart.

This unit had been running and powering my friends house on a backup basis 8 years ago. Old fuel caused plunger sticking and the drive key broke. I swapped that out and it worked again. Few years later bad fuel..see the issue? I put it back together correctly with the same pump, shims and...

Running with no load for 5 minutes and it shut down after the air shutters opened maximum. Checked the thermal protection and it tripped. Smoke from the cylinder head. Felt hot.

This is the thread I need..working on a 003 that is driving me nuts..flow timing shows timing off but PC mark and face gear alignment spot on. The IP has a history of breaking the drive key so I'm thinking it has damaged the drive key instead of breaking it. This would upset the distribution...

Interesting. I was under the impression it seals the delivery valve to the plunger housing. But if the d valve is lapped to the head, it should seal. could it be your spacer is stuck in the head?

The 1/8" pin in the side indexes the pump to the port closing (PC) mark on the flywheel. The cam gear to injector pump face gear teeth are quite coarse, you will get correct mesh. The PC mark lining up only happens on #1 compression so remove the valve cover and make sure both intake and...
