Causes of low compression

[sd455dan]

The first machine shop i sent it to performs 99% of their work on gasoline engines. He did mine as a favor since he knew me and business was slow. I asked him to put new guides, seats, and valves in, but he told me a set of guides and a simple grind would be all it would need.

Maybe he didn't realize a proper valve job was critical in a diesel because of the higher amount of compression.

Maybe he let one of his slacker employees do the job.

Maybe hes just getting old and senile.

Who knows, but i've heard several others tell me hes had a bunch of comebacks in the last 2 years.

Glad to hear you have the Ford on the Mend and- Sorry that the 1st shop blew the head rebuild, It has happened to a few of us.

I am sure there are some great small machine shops that do engine work, but there also seem to be a few irresponsible operators out there

here's to hoping TBNers are fortunate in finding a good shop (the first time)

If you ever need more machine work, try to get it to that shop with the old guys that Adiredneck used!

I forgot all about his nightmare.

10 years later….

Just to give a final conclusion on this thread.

After I had the injection pump rebuilt and installed, the tractor started on its own without ether.

I hooked it to a disk and spent the day cutting about 5 acres, lugging it down to set the rings in. The next day I hooked it to the bush hog and did some mowing. It ran great and did not slobber any oil when idling.

I spent a lot of time chasing the manuals specification of 500 psi compression. Maybe that was a misprint, I was measuring it wrong, or there was some other factor involved. I live on the coast, so elevation is not a factor. Regardless, it does not take 500 psi for these tractors to start and run properly.

This was my neighbors tractor and after the repair he has continued to operate it without issue.

This was the only picture I took of it, when I had the head sent to the 2nd machine shop.

Thanks for all the input and helping me brain storm!

It’s nice to hear back from you. Glad you got it going. I hope your neighbor appreciates your hard work.

Thanks for the conclusion report. Don't always get to the answers.

Yes, that’s always a drag when you find a thread posted by someone else with the same exact symptons/situation you’re experiencing and they ghost without leaving a resolution.

I’ve been busy last few years. Changed jobs, got married, had a little one, and went back to school.

I haven’t posted anything, but I’ve been lurking through the threads when I have a minute.
