JohnD Posted March 14 Posted March 14 I've just changed my differential. Balancing it on the jack, to lower or lift the new one back in, is fraught with danger! For your fingers, head, and as you need the whole car quite high off the floor, to the diff itself if it drops. So I built a bearer for it, that would provide a flat surface for the jack saddle. I built it from scrap wood, ad used a large cable tie to hold the diff onto the bearer. Photos and a sketch plan below. The width of the base is irrelevant, so I've only included those that engage with the rear housing (mine has a drain plug) and either side of the diff mounting plate. Hope it's useful! John 1
Escadrille Ecosse Posted March 14 Posted March 14 Nice Know what you mean about trying to manoeuvre the diff with it perched precariously on the jack.
PeteStupps Posted March 15 Posted March 15 That's very useful John, thank you! I hastily took the diff off my dormant brown Spit-6 several months ago for reasons which now escape memory. Keep tripping over the blasted diff, and can't move the car in the meantime, so want to put it back. A device like yours would make the job a bit less daunting, I shall get sawing.

I had a short-lived burst of motivation to work on the car, and decided the diff (noisy according to previous owner) was the place to start. In retrospect seems like an idiotic decision...

JohnD Posted March 15 Author Posted March 15 (edited) Problem with replacing is that while all the bolts come with specified torques, there's no room to get a torque wrench in there! Hohum, just heave on it until you can't move it anymore! And why Triumph never fitted drain plugs - well, I know, to save money - but now they are 50+ years old they really should get them.

Hohum, just heave on it until you can't move it anymore! I found a couple of extension bars gets the torque wrench far enough out to work, with a ring spanner wedged against the chassis crossrail to stop the bolt turning. 12 minutes ago, JohnD said: And why Triumph never fitted drain plugs - well, I know, to save money - but now they are 50+ years old they really should get them. Agree wholeheartedly. Also found that drain plugs are easily installed off or on the car with a little care.
JohnD Posted March 15 Author Posted March 15 (edited) Yes, to both, Colin! But the output and input flanges? I have a small, low torque ( up to 40 lbs.ft) wrench and i can't get that in. There must have been 'special tools' on the production line! Edited March 15 by JohnD

The good old two spanner grip to tighten these awkward little blighters
