CJ body mounts torque
Hi all,
I'm in the process of replacing the body mounts and bolts on my '82
Scrambler, and I can't seem to find the torque in the factory service
manual. Anyone know what it's supposed to be? I've had to cut out all
the old insert nuts and am replacing them with 3/4" grade 8 bolts and
nuts, so I need to know the torque more to keep from squashing the new
urethane bushings too much rather than for breaking the bolts :).
Thanks.

Re: CJ body mounts torque
I do not think 3/4" bolts will work. They will fill the hole up so
there is no adjustment on the mounts and you 'Do' need adjustment space
so you can square the body with the frame or things like the clutch
linkage won't work and the shifters can hit the tub or the shifter boot
binds or the wheels stick out on one side....
The mounts also have a metal tube in their centers with washers that fit
the 3/8" bolts so they cannot be compressed too much. They have a
washer, then a thick donut on top with a metal tube that fits loose
through the frame plate and another thin donut that goes over the bottom
of the metal tube with a washer so the frame plate is sandwiched
between. This makes for an up and down vibration damper.
Someone on here gave me the torque settings once, Bill maybe. I think
it was someplace around 50 ft lb, but don't remember. I can feel it
when mine come up tight to the inside tube so the rubber is compressed
as far as it compresses. I then go one grunt past which is about 50-60
ft lb for 'me'....

Re: CJ body mounts torque
Mike,
Thanks for the info. I'm not removing the body, only jacking it up far
enough to remove the bushings. So far, all of the new 3/4" bolts have
slid right in, so I figure my alignment won't signficantly shift. If I
have problems with alignment, I'll try switching to a smaller bolt
then.
50 ft-lbs sounds about right for hardened bolts of that size. That's
about what the transmission bolts are, if I recall. I just don't want
them coming loose once I weld plates over the holes I cut (I'm also
using lock washers).

Thanks for the info. I'm not removing the body, only jacking it up far
enough to remove the bushings. So far, all of the new 3/4" bolts have
slid right in, so I figure my alignment won't signficantly shift. If I
have problems with alignment, I'll try switching to a smaller bolt
then.
50 ft-lbs sounds about right for hardened bolts of that size. That's
about what the transmission bolts are, if I recall. I just don't want
them coming loose once I weld plates over the holes I cut (I'm also
using lock washers).
