Could I use this drive plate ? its the best I got , it has this small crack I drilled a hole as to stop its travel
[in case it wanted to keep on going]I wanted to braze it but was told it will warp the plate thank you ..lorenzo

I think that's a casting flaw and not a crack. It's not in a critical area and should be fine to use as-is. I would not braze it.

Lorenzo, can you tell if it extends down along the side of the hole. Pour some alcohol on it. Then wipe the surface of the plate dry and watch it to see if anything bleeds back out from the void.

A couple things about cracks in steel. Normally they don't open up like this one is. If you run your finger nail across a crack in steel you normally won't catch your nail on the edge of the crack. If your nail does catch it's probably because your looking at a scratch and feeling a burr. Normally if you can see a crack it'll extend into an adjacent surface.

yes after observation on the back side-it is a crack , is it safe to use? or braze it?
Thank you ..Lorenzo

You can wire feed weld it.I had to close up elongated holes in mine where the clutch ring goes. Do it slowly ,a bit at a time.

Hey Lorenzo,
If you dont feel like using it , i know someone who might..........

Would crack repair screws work? They sure hold a block or head crack together. PK

I had a friend do the face of the plate on a 3 jaw chuck lathe, ,and now I cant get it to work , the drum and plate, when I tighten the screws on the plate it locks against the top of the plate bushing on the transmission shaft I was getting about .6k run out now its 15k at best i need a machinist to see if this can be saved or junk the hole thing and quit this,. its making me sick
one step forward a mile back
sorry I ever started this
Well thank you all for the help , best wishes to all to all..lorenzo

Lorenzo, something else about cracks; often you can't see the entire crack. It's possible for it to extend beyond what you can see.

What Michael said. Dave

That would scare me. That plate takes the pressure of starting in low. It also takes the pressure of braking. These are in opposite directions and if you have chatter in the bands it would also cause more pressure on that piece. It is also hard to replace at a later time Almost impossible without pulling the engine.

If at all possible try to find a better plate. At least that's what I would do if it were mine.

I don't know if you have rear wheel brakes or live in a very hilly area, but I would recommend them if you use this plate.
Norm

Yes Norm I will look at the classifieds and see if I find one sure is a shame it' was a good one
Thank you all for the input..lorenzo

You're overthinking this. That part is fine to use.
