Rumbling when releasing clutch from start

wareagle · Jun 30, 2011

I am still getting a severe rumbling of the whole truck when I put in 1st gear and start driving. Goes away quickly, but is still there. The flywheel has been resurfaced and I have a new clutch kit on it. Supposedly the drive shaft was balanced as well...

Anyone else know what else it could be? I have a 1970 F100, 360 with a T85N 3 speed tranny..

Thanks in advance,
Steven

A rumble-like noise as opposed to "jumpy" feeling?
Got to get it straight what you mean first.

where does your exhaust exit? under the truck or out the back/side?

I had a fly wheel resurfaced once and it didn't help it. Had to replace it.

More like the whole truck just shakes, but just until you get it up to around 5-10 MPH

Runs under the bed and out the back. Single exhaust w/ a Cherry Bomb.

Ughhhhhhh... Not what I wanted to hear. Easy fix while the tranny was out.. How difficult would it be now?

Is this after you have already released the clutch ?

During the process of releasing it. May have been a little off on my 5-10 MPH.

I have been driving manual transmission vehicles all my life and have never experienced this before.

Sounds like a warped flywheel causing clutch chatter.

You know Sean, I wouldn't doubt it given the problems I had with the shop that "repaired" my overdrive tranny that no longer has overdrive...

I will leave that whole story for another day....

That's exactly how my '75 acts and it's not the flywheel! :/
It's a crap-job lining up the bell housing on the motor. Read
(on the internet) where all the big-three were sloppy about
that back-when but Ford was the worst. My clutch has been
bad since -before- it had 14.1 miles on it. It was crummy
leaving the dealer's lot on the -test drive- after waiting on
the special ordered pickup to come in.

Thought it'd smooth out. :/
I was young and dumb, what else can I say?

I have been driving manual transmission vehicles all
my life and have never experienced this before.

So when did this start acting like this?
Etc.

Steven, quit making us pry information out of you.
Tell us the story.
Go.

ps- It's easy to take out a manual transmission...

...especially now that we got the internet. LOL

It has actually been doing it since I bought it last June. Bell housing, huh?

You know, I have just always preferred a manual transmission for some reason. The 3 on the tree was a novelty I have wanted since watching my grandmother driver her old Belvider (SP?)

Hey Alvin, what did you ever do about your miss-aligned bell housing???

Well, since I didn't have a dial indicator with magnetic base and besides
I couldn't believe Ford would do me that way...

I took it apart and swapped out the bronze/iron oil-lite pilot bearing for
a 6303 sealed ball bearing as a test and did nothing else. That was really
tough for me to do since I always did everything when I'd took it apart.

That fixed it about half but was told how to fix it later and will be doing
that pretty soon since I bought a new LuK diaphragm clutch kit for it.

The trick is to use the dial indicator and tighten the bolts after gettin' it
lined up perfect then drill the dowel-pin-holes out to the next size up.

No need for those weird off-set dowel-pin things.

Hmmm... I still need to get some larger dowel-pins tho. :/
Thanks for reminding me.

Sorry, this dumb, retired, ditch-digger didn't mean to talk down to you.

Google:
clutch chatter
dial indicator
6303 bearing
weird off-set dowel-pin thingys

bellhousing re-alignment <-- that one I'll do when I get back from the missile silo!

Just kidding!!! Will google that this weekend, right after I put my new regulator/recrifier on my VN750.

And isn't the word thingy a lot better than thingamajig
