The Stovebolt Site Forums The Parking Lot Big Bolts Mountng Brown Lipe

I'm fixing to mount a three speed Brown Lipe in my 46 1.5 ton Chevy. Should it be bolted straight to the frame or insulated with rubber pads.

Some sort of rubber pads would be best. Most all the factory installed auxiliary transmissions I have seen have some sort of cushion mount.

Thanks for the reply. The mounts that came with the brownie suggested that it was mounted solid which looks like an open door for problems. The tech link didn't work but I think I can do the shafts and angles with no problem.

Try the link again, should be fixed now.

I expect it would be OK solidly mounted, but be quieter and kinder to the frame and mounts if it is somewhat flexible. Either way probably fine..

Hi ttodd. I would suggest installing your aux. transmission with rubber pads. As Grigg says it will be quieter and easier on the frame. Here is a picture of how I did mine: http://good-times.webshots.com/photo/2236843520099958186JSAyns

It's a little hard to see, but there is an angle iron bolted to the frame that the rubber pad sits and bolts to. Then the aux. transmission mount has an angle iron that sits and bolts to the rubber pad. There's lots of ways to do it depending on the type of pads you have. But haven't had any trouble with this setup.

Also just a side note. I mounted the aux. trans with the rear yoke right where the carrier bearing used to be. That way you don't have to redo the back half of the driveline, you'll just have to shorten the front half.

Good luck and hope to see some pictures, Paul.

Not sure what your front mount is, but the rear would be two ears that would pad mount to a corisponding bracket, these mount solid, the front might be a yoke type bracke and it would have a rubber V Belt around the inside of it where it contacts the trans, it too would be bolted solid to the frame.

Got some rubber body biscuts and some 3/8 X 2 X 2'' angle iron gonna mont it this week end. Planning on taking the old truck "Ralph" to Hutchinson Kansas truck meet in May, hope to see some Bolters there.

One precaution, if you're not aware of it already, but it's a little risky to drill holes in the frame flanges to mount your brackets for the Brownie. Fabricate a 90 degree angle at the ends of the angle iron brackets that's a close fit to the inside of the frame rails, and drill bolt holes in the vertical section of the frame. That's how we mounted auxiliary transmissions on the big rigs I used to work on. Drilling the flanges, particularly on aluminum frame rails, creates stress risers that can break a frame in two across a drilled hole.
