Just found this.... so posted for info....
Somebody please tell me why I have spent hours taking my Hi-Torq mini starter off my small block Chevy only to have some screeching noise come from where the flywheel catches the starter when ticking over?
The story is... Starter on the roadster (2-shims) was getting very hot and draining the battery power, so I took the same starter off my old rod (0-shims) and fitted it to the new motor and replaced it with the 2-shims that were originally fitted. It made that horrible noise every time. I've tried butting it tight upto the block, fitting 1,2,3-shims, even gone to washers to try and space it correctly, it seems to me it's not the distance up and down that's the problem, it's the movement back and forth, it's as though the starter sprocket needs to go into the starter body a bit more, although it's in as far as it will go, or even if the 3/4" thick sprocket should be 1/2" thick so the flywheel didn't catch it.
I noticed on removal, the starter sprocket had the edges worn off it quite alot while in use. I couldn't get it to work perfectly originally on fitting it some time back, although the slight noise I had went away in time, obviously wearing the edges away, but it did do it more in reverse... Why?
Any advice would be gratefully recieved as I'm banging my head against a brick wall with it!
I fancy grinding the edges off the new starter, at least I might not have that horrible screeching noise!!!
These gear reduction starters, provide far more torque than the std unit. The
PSL100 is smaller & lighter, and can be turned through 360 degrees. All 3
models need a "straight" bolt pattern. 153/168 ring gears ok. With mounting
bolts & shims.
This starter is very difficult to install unless you can see the engagement of
the pinion, into the ring gear. [easier when the engine is out]. Also, you will
need to protect the starter from exhaust heat. Either- wrap the starter or the
headers with a heat resistant bandage. Heat will destroy the starter. Oil
dripping on the starter will also cause failure. Check the engagement in both
directions- 1. The pinion should engage 1/2 to 2/3 the way across the ring
gear, not all the way across. 2. Check the shimming information on the next
page, regarding depth of engagement.
