fixing specs

Post by tone » Thu Oct 22, 2020 5:21 am

Im sure this topic is here somewhere just can't find it!
Is there a definitive list available detailing the various fixings thread sizes etc?
I have a few bulkhead bolts missing but don't recall them rattling loose
Also various nyloc nuts which I would like. to replace
I also have to replace the spring shackle rubbers, and the old nuts could do with being replaced

On the spring shackles is it best to stay with the rubber bushes [I hear the ride is softer, but its still pretty bumpy] or go for poly bush and have my remaining teeth rattled out!

I assume you are talking about a TC? There is a spec book 259, which lists literally every bolt, nut and part on a TC. It is a factory book not intended for the general public, and is very hard to use - un-indexed. Copies, some better and some worse, do exist; the original is very very rare. Doug Pelton might sell you a copy.

Your best bet for niggling details is to look at the various parts vendors, especially Doug Pelton at From the Frame Up. Doug's shop is dedicated to TC's, and he also sells nifty little sets of commonly-used bolts, like firewall bolts and tub-to-chassis bolts. He also has nuts, bolts etc. individually, but buying a baggie is much better, and all the bolts match then.

As for suspension bushings, opinions differ. The rubber works fine, and is original. But if you are going to drive con brio, then the poly bushings (black, not red) will stiffen the suspension noticeably. It makes more of a difference in a TD, where there re more bushings to stiffen thingfs up.

I pretty much agree with what Tom has said. There are several lists of fasteners out there, but unfortunately for whatever reason their authors have declined to let anyone have a copy. I tried unsuccessfully to combine them several years ago into one master list. There are engine fastener lists in the resource section of this site if you need them.

The difference in bushings is pretty much what you would expect. The rubber will ride a bit softer but the polyurethane bushing will give better lateral control. They will also last longer than rubber. The difference in writing performance isn't extreme. A panhard rod is another way to sharpen steering response without sacrificing ride quality.

Roger Furneaux ("Mad Metrics") in the UK is the source for the useful Panhard rod.

Short of threadlocker, nothing beats a properly "sized" and installed split lock washer for bulkhead/chassis, even in the most extreme conditions. As original to the TC.
