Torque spec? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

TheSlowNorris · 11-04-2009, 12:44 AM

Howdy, new to this board and most of my time is spent fooling w/ old Jeeps, but I just got 71 lwb C/20, 350, 4 on the floor...

My cab mounts and radiator mount were completely rotten. I ordered a new set (6 in all) in rubber (It's 2wd, so I would like to keep the ride at least stock smooth (Love the old trailing arm suspension)).

I pretty much figured I wouldn't get a torque spec for these mounts. Does anyone know the torque specs?

There are 2 for the radiator mounts, 2 front cab mounts, and 2 rear cab mounts.

TIA

BTW, I have been lurking for a few weeks now and I must say everybody on the board seems super friendly... good community... Look forward to hanging around here.

Welcome to the board from Lake County California. Sorry I can't give you specifics. The best I could come up with is two grunts and a jerk with a knuckle buster.

Seriously, someone out there with a factory service or assembly manual should be able to help you out.

I believe all the factory fasteners are lock nuts. The torque isn't what keeps them from backing off. I try to tighten until the rubber doesn't compress any more. The metal spacers and washers should have no gaps.

The forward mounts are nylocks, but the rear are not just bolts w/ a rectangular nut in the cab... The radiator mounts are nuts w/ jam nuts.

Manes Truck parts were really fast in shipping, but I emailed them to ask for a torque spec and haven't heard back?
