Hello Onan Masters! I am new to old Onans and this forum. I have learned a great deal after spending a couple hours reading previous posts about these wonderful, simple diesel generators. Thank you. This one can't have more than a couple hours of run time, just sat as residential backup. When I got it, I found the starter solonoid inoperative - took it apart, cleaned the contacts and had starter. Next was fuel system - drained & cleaned fuel filters, repaired pre-pump glass bowl leak [gskt] and used the manual primer to get fuel to the inj pump. Cranked it over and had fuel flow thru the return, figgured I'd fire it. Shot some PB Blaster into intake,cranked 'er, got her lubed up and then put the glow plugs to her. The old beast fired but didn't puff more than a couple strokes. Check for fuel delivery at the injectors,[remember my Dad doing that on his D4 Cat] and had none.Tried again with the PB but after keeping DJ running by direct injection down the intake, the head gskt blew. Found the govoner linkage seemingly frozen at the actuator shaft in the inj.pump.Tried freeing it but something was not right. I have no service manual for DJ and could'nt find an on-line one. So, I got my hands on a head gskt, replaced it, took the inj pump off and dove in. Took some time but after looking, poking,twisting & prodding I got the pump apart without mangling it. Cool & simple, found the plunger & fuel limiter [govener] stuck. Not much was corrosion, the working parts were fine so I cleaned & freed it all and reassembled DJ. I cranked it untill I had fuel to the injectors, primed it w/ some more PB and fired. A moment of rough running, cleared up and really ran well for a 3-5 min spell. Then she died.Fuel delivery ok @ injctors, so I took out the injectors - no spray. Shoulda' figguered that! [read a post that talks about a similiar situation] Now, I have disassembled the injector down to body and inner shield [a sleeve between the injectr & cooling body] and have determined that I have crud stuck in the inlet pressure side after the internal check ball and have reached a point where I can't figger out how to get the restof the injector apart. Anybody know how? Is it even possible? And, got suggestions on waking up the generator part.What can I service to help make sure that 3 times be a charm to success. Sorry for the long post, hopefully the details will help give the best direction to advise me. Thanks.
