I have a 92 Sierra 1/2 ton. It has a 350 Goodwrench crate engine in it. I took some pictures of the block and head numbers when I got the truck but lost them in a hard drive crash.
Best I can remember the block had a mid 80"s casting and the heads had a late 70"s casting.
My problem is that I had to replace the starter and I order everything online to save money. I chose a starter from an 87 Suburban with a 350 and ordered the starter. I did not think to check every tiny measurement while I had the core at the auto parts store (ship to store). In this case I would like to have checked out the pinion travel distance. I know the 80 year model had the same bolt-on pattern but it was a different part number so SOMETHING was different.
After putting it on, the pinion stop collar is really, really close to the flywheel.
I have uploaded two pictures of the starter and the flywheel area and an mp3 file of it starting. Something is just not right.
There is ONE area (about 6 teeth on the flywheel) where you can see where the old starter did some damage. 99% of the time it will start ok but it sounds like the pinion gear is not releasing immediately and there is a small grinding type sound at the end of the cranking cycle. There was ONE time where the pinion gear did not lock into the teeth on the flywheel and I just got that grinding noise. We've all heard it. Starter pinion tries to engage but just grinds trying to get into the flywheel teeth.
There was no shims on the starter when I took it off so I tried to widen the distance between the pinion collar and where the pinion should mesh with the flywheel. Can that be the problem"
Here's the other thing, the kids put the newer style tranny in it. What is it? The 700R4, I think. So I am wondering if there is a compatibility issue there?
Anyway, I did the best I could taking a couple of pics but the exhaust system was sort of in the way.
Can you experts please take a look at the pics and listen to the short MP3 and let me know what you think?
