Alright to get you up to speed. 29 model A Boxed, X-frame Radius rods from backing plates and mounted to X-frame. 59A bored, stroked, ported and polished early 90's Ford F-150 RTS 4 speed toploader overdrive Here is the ask: When the clutch is released I get a heck of a shudder. Front motor mounts are new... and transmission is secure. +No anti chatter bars. Would these fix the issue? What the hell do I do? Will add a video shortly
New clutch disk, flywheel, and throw out bearing? Old flywheel? Was any cutting done to true up the flywheel before installation? What linkage set up do you have? Does it shudder when you dump the clutch or if you try to ease it out slowly? Need more info.
A few things could cause this; Worn clutch and/or flywheel Bad throwout bearing And lack of chatter rods Good luck
If it’s a new clutch disc, it could be the compound of the disc linings. There was a brand of clutch disc sold back in the seventies that was notorious for engagement chatter. I would never use that brand, thankfully I don’t think they are still in business. With most things now being make overseas, no telling what they are putting in clutch linings these days. Sometimes oil on a disc will make it grab, kinda backwards to what a person would think! Lol Just a couple of possibilities. Bones
Old school way------bumper up to a solid wall, rev it up & slowly release the clutch, let it "burn in" a few seconds, repeat, then go try it on road.
I vote for anti chatter rods also . There is a wave spring between the lining sides of the disc , there is a major difference between OEM and aftermarket wave spring . I had an old Ford chatter so badly it would shake the ash try open . Everything was new and resurfaced as it was supposed to be . I did not one thing other replace the disc with OEM disc and smooth as a fresh shave with a Wade & Butcher after the disc swap . This is where under close inspection I noticed the wave spring difference .
