 Topic: 7030 Timing Issue
Posted: 21 hours 6 minutes ago at 7:49pm |
7030 - unable to get it to start. Rebuilt injection pump, rebuilt engine, new starter, new batteries. The engine doesn’t appear to be the original. I attached a picture of the tag off the engine. We tried timing at 24 degrees, but all it does is smoke. The engine says 1-31-1979, so guessing this isn’t the original. Wondering what we need to do to get it fire. Thank you!

You sure it is not 1/2 off on the time. Line up marks in the pump, take drive gear off and turn crankshaft one round, install gear and try.

Whomever did the pump has to tell you what to time it at. A 7030 pump is 24 degrees BTDC. BUT, if it has been updated to 7040 timing advance it is 16 degrees BTDC. FIGURE IT OUT or you will ruin the engine.

That would have the rubber ring balancer so timing marks could have slipped and be incorrect.

Another perfectly good reason to align the pumps timing marks BEFORE removal so you KNOW where the running engine was timed at to begin with !!!!

We came here looking for help. If we knew what kind of remarks we would get, I wouldn’t have bothered.

You've been given damn good help. The rubber mounted crank pulley can slip and cause you the installer timing issues because the numbers are wrong. The pumps static timing numbers are different between engine models and depending on what repairs have been done to it over the years. Incorrect timing can and will burn the piston bowls, so getting it right is indeed important. Your feelings are hurt over this ??? You've got everything you need to know right here and you're not taking advantage of it?? Good luck.
