It wasn't the starter, it was the engine bolt just to the rear of it. Next time I'll pull the engine with the plate, instead of just the engine.


No progress today, I got distracted with a (10) hour road trip!

Here's how we spent the day;

The good news, the 782 will benefit from it. I wanted to add power steering, and dual rear brakes, now I can add front hydros too!

I see that link no longer goes anywhere. I spent yesday driving down to Mt. Orab, to pick up a 2072 cub for parts.

No work in the garage.

Nothing good to report. Tried to fire it up today, but it will not run for more than a few minutes. More disturbing than that is it's not circulating any oil. Nothing going through the lines to the filter, or the pressure gauge.

Must admit, I've had better days.

Wow, you went past my house and then another 3 hrs. Three hours one way was too much for me! I may have went that far for a super diesel for $400!

I'm glad it wouldn't run long--IF you don't have oil pressure.
Try taking the filter off or loosen the adaptor you made, take the spark plugs out and crank it, you should get oil.
Only thing I can think of is the roll pin in the gear that drives the pump shaft is gone or sheared-- (page 7.1 in the manual) but that would be rare.
I am hoping it it is just slow to prime.
Do find the lube problem before you try run it any more.
IIRR the pump can be accessed with just the end cover off, but the gear/pin needs more disassmbly.
We all make little mistakes do not be discouraged.
You have come so far!!

Thanks for the encouragement.

I did loosen the oil filter and some oil did run out. Then I removed the return line from the reomte filter head, no oil had passed through it.

Next I removed the fitting for the oil pressure gauge, no oil there either.

It never ran more than a few minutes at a time, but I am very concerned at this point.

When I had the motor on the bench, I did not reomve the roll pin, from the oil pump drive gear.

I did remove the small cover and take the inner and outer rotors out to clean them. I was careful to put them back in the same orientation. Then I filled the cavity with clean oil, and put the cover back in place.

I did remove and clean both the pick up tube and housing.

I have been wanting to convert my 782 to power steering for a while. This semmed like a cost effective way to do it? Not so sure now. What's done is done. He came off his price to $350.00. I'll part out what I don't put on my 782.
A couple of pics from it loaded up.

ok, even if the pickup tube screen was amiss it is still below the oil lever so it should suck.
Did you put the pressure relief spring/valve in the end cover?
Maybe it fell out, but thinking it still should pump just be low in oil pressure.
If after some more trying and no joy I would pull the end cover and check the relief assy, if good, remove the pump cover and see if the inner rotor shaft can be turned--guessing it is possible that the roll pin was previously sheared and went unoticed I just hate chit like that, that I maybe missed.
but WE wouldn't be doing this if we didn't like it.
Again, Luck!! We will get you up and running

Yes, relief assembly went back in ball first, then spring. I am confident that the roll pim was intact, I remember spinning the gear after putting the rotors back in, checking for smooth operation.

Thanks again.
