Thread: Are the TD5 nuts and bolts metric, imperial or both?

I believe you are correct. Some of the bolts and nuts do seem to appear imperial. I am sure that someone whose knowledge far exceeds my own will let you know for sure though.

Yep both.

Does anyone have a list of which fittings are imperial?

There appear to be only a handful on the Td5, but the V8 appears to have quite a few.

I've had a quick look at Microcat the first ones I found that was imperial are the propshaft nuts and bolts which are 3/8 UNF. The rotoflex end uses M12.

For the Td5 at least the vast majority of fittings that I've been able to locate in Microcat are M size (with the exception of the propshaft fittings) with M6 (10mm), M8 (13mm), M10 (16mm), M12 (18mm) and M16 (24mm) being the most common.

Propshaft is what sprung to mind for me, but I would assume anything that is carry over and from the motherland like diffs, maybe transfercase etc.

Exhaust manifold bolts and nuts are 1/2".

90% of the td5 is metric. (including the torqz bits)

the imperial is mainly the 3/8-1/2- 9/16 and 5/8 sizes...

The oil lines are imperial but the metric open enders fit well enough for the job.

A set of R/oe and the sockets in the above sizes will work.

Someone must have replaced the original studs if that is the case. The factory exhaust studs are M8.

M8 x what? ALWAYS quote the pitch no matter what system of fastener you are referring to. This avoids errors. In M8 the following pitches are in relatively common use. 0.75, 1.0, 1.25, 1.5.

I know people tend to use "M and a number" to refer to ISO Coarse. Just keep in mind that ISO coarse is not the only pitch used in a given diameter. Some diameters have five pitches in relatively common use.
