A question about Bill Bs beam plates. - ZR-1 Net Registry Forums

Z51JEFF · 10-14-2017

If I do replace the exhaust on my car I'd like to put the beam plates in that I've got. Is this pretty straight forward,does anything need to be supported during the process?

Very straight forward. Most difficult part may be getting the OE nuts OFF.

Once they're off, just slide the plates in place with the nuts over the holes, and thread the bolts up into the self-centering nuts.

Bill provides some lugs to assist with positioning the transmission tail properly w/in the tunnel. If you don't have them, you can make them out of a wooden dowel rod.

I had to take the torque off the motor mount nuts, along with the C-beam nuts, "center" the trans with the guide slugs, and then torque all the nuts down.

Never had any drive train vibration, once everything was torqued/spaced.

Good luck!

Follow Bill's guidelines for preparing the mating surfaces. A clean, flat contact area for the plates allows the torque specs to fully clamp down. Rough spots will allow for partial contact, thus loosening. Overtorquing the C-beam can lead to problems as well.
Transmission whine alignment shall be corrected at this time.

Pay attention to step #4, removal of original washers, delete them. This is an important step.

Problems corrected will be; gear shifter rising and rear-end kicking out when accelerating rapidly. Basically, car now launches much straighter, driveline feels a little bit more secured.
Worth every penny, genius modification.

Paul is correct it's a tight fit tool wise and they are on tight too boot tourqued to factory specs. However, it's a well worth it mod for structural rigidity and if you have to go back R&Ring the transmission is a heck of a lot easier.

It’s been a while since I did this. About to install a set on the new Z. Does it require the use of adhesive between the beam and the trans?

I'll have to call Bill B and get some of those dowls,guides. Here's ago I pulled the trans out of an 84 I had at the time and I had to -modify- a wrench to get to the top bolts,it should be the same setup at the top of the C beam for the Z I'm hopping. Anybody know what size the nuts are?

I did mine on jackstands in the garage - when I had to take it all out to replace pilot bushing. Something I did that I didn't see in the link - and I think it was in Bill's directions - was to use Window Weld between the plates and beam. I did this over a year ago so I can't remember exactly. And that chitt is NASTY. Be sure to use latex gloves because it will NOT come off your skin. I don't remember having to modify any wrenches to get the old ones off either. It was a pain but I got it.

Interesting... just checked the instructions included with Bills Beam Plates. No mention of adhesives.

I recommend supporting the back of the motor or the transmission when the C-Beam bolts are loosened. It will be much easier to get all the bolts back in if the transmission position can be adjusted to align the C-Beam.
