Clutch Chatter Vibration

[55 Fargo]

Hi all, okay so I have had some vibration from the driveline, on take off lately.

My clutch was new 2 years ago, flywheel machined, no oil is leaking in there either.

My rear motor mounts are toast, the new ones from Roberts arrived today, so they will be installed maybe tomorrow.

I did an adjustment on the clutch linkage, it helped quite a bit.

I am hoping the new rear mounts will also help a lot too. I have installed brand new U-joints last week.

My question, is how many of you have had similar problems.

I know last year I was having chatter/vibration on take off, and after I adjusted the carb, it was much smoother, coincidence, or not..........Fred

do not over look the rear shackle bushings..and odds are you will have to revisit the linkage when all is put right again..

Probably not coincidence. The engine is put under stress when pulling out and a properly tuned one will respond smoother. I have seen engine electrical issues cause shuddering when under load........Tim

I know there are lots of things that can cause chatter, but this is my experience with a similar situation. May not be your problem and hopefully not. I restored a 67 F-100 quite a few years ago. I had the flywheel resurfaced, remanufactured pressure plate, and new disc. The engine was rebuilt with new rear seal and there was no oil anywhere inside the bell housing. About a year or so later, I started getting a chatter when I let the clutch out. After a whole lot of trouble trying other things, I pulled the tranny and replaced the pressure plate and disc. This time I used a new aftermarket pressure plate and disc, I believe at the time the manufacturer was "Zoom". That fixed my problem. I always suspected the remanufactured unit had springs that were too weak, but that was just an assumption. I put a lot of miles on that truck and never had the problem again.

Hope you fix your problem without too much trouble. Good luck!

I adjusted the throw out rod today, that made a huge difference.

i still have to install new motor mounts, that should help matters to.

I had my flywheel machined, the clutch and pressure plate, were both NOS Borg and Beck, and should be okay. This past spring, the clutch was doing the chatter on take off, then it suddenly stopped doing this, and reappeared in fall, so what gives......

Fred could be moisture getting into the clutch disk. My dakota has done this for many years after really rainy or humid days. Goes away after a bit of driving.

Sounds like a doozy of a problem, the kind that can drive you crazy looking. You and I must share a few traits, seems I hardly ever get easy problems. I'm crossing my fingers and hoping your new motor mounts will make the difference, certainly makes sense.
