i keep going through flexplate and starters

[K-5kid]

i tried to shim and i fabricated a bracket for my starter but i makes this bad grinding noise. what could it be. I need to replace my flexplate now and i think maybe the starter. i am stumped

Try to make sure you have the right flexplate on it. Maybe someone put one off a 400 or something. Does the motor run rough at all.

when does it grind? when you start it, after you start it and it still grinds????

is the teath on the starter chipped? the fly wheel?

 

[K-5kid]

it grinds when i crank it but then stops and the flex plate could be wrong i am going to rip into it on saturday

what kind of bolts are holding your starter on? a stock gm starter bolt is "sleeved" and pretty much centers the starter while u bolt it on. ive seen some people use a regular hex head bolt and the starter will actually walk around on the block- which will cause grinding noise. so make sure youve got the factory bolts. good luck ryan

ive had a starter that did the "walking" like short sub said, but it was with the factory bolts. turns out the nose cone bolt holes were wore.

yea i am going to try to fix it this weekend so it wouldnt hurt to get new bolts i will give it a shot

well making a bracket tells me you got something wrong anyways, there is no reason you should be having ot make any bracket for any chevy starter unless you have something like an old iron manual bellhousing and a super old engine block like 55-early 60s or something, other than that no really,

you should have three threaded holes in engine block for starter noses,

what engine year and size
what size wheel
what crank year and RMS ?

which starter nose bolt pattern you runnin

make sure your shim is correct, if it is to loose it will grind and strip the flex plate
