5.7 LX starter

[AKJohne]

1996/97 5.7 LX 0K158784
recently replaced the old motor with a new long block.
Starts, runs, however the starter is noisy, I would not call it a grinding noise. I know SBC's often require shimming the starter, which we did not do. I will investigate further this weekend, I just thought I would ask, what should I be looking at/for?

If you have a newer permanant magnet starter and didn’t use the correct bolts for starter it may not be tight, old bolts will bottom out but starter wont be tight. Hopefully new bolts came with starter ?

Thanks for that, I reused the original starter, presumably from 1996/97.
Assuming old starter/old bolts should be OK?

Worn bearings or brushes in the old start motor?
I'd pull the starter and either have a shop look at it, or bench test it yourself.

quality SBC starters havent needed shimming for almost 40 years

I would look at the starter bendix

Get one anyway. Ease of installation alone makes it worth the money. I've used db electrical for a few starters and alternators with good results. Very cheap as well

Just as an aside, my boat got submerged at the end of the season last year, working to restore it, I disassembled my DB electrical starter and cleaned it, rebuilding the carb as we speak, will fire it up either this weekend or next, I'll update my ongoing thread with that

 

[AKJohne]

I will remove it this weekend and do some ciphering. The existing starter had 3 lugs, 2 if you don't count the one to the solenoid. Seems the new ones all have another lug. I remember seeing that before on here, but dont recall what the additional lug is for?

That looks very much like a permanent magnet gear reduction starter already.
