So been a long time no updates.
Got the car running with the help of Pete (Valiant) about 10 months ago, then spent the next 3 nights doing the full exhaust system.. On the friday I'd worked from 7.30 - 5.30 without any meal breaks flat stick at my old job. Decided I'd come home at the end of it and finish off the exhaust. Pete came around at 10.30 just as I was finishing up and convinced me I needed to take the car for a quick run - I was initially against it due to tiredness. Forgetting that way back when I first put the diff it the diff hat had had a small pin hole leak in it, which Zac had tig'd up, but then I'd never filled it with fresh oil afterward, which is fine when it'd only been pushed down the street to Barts or off a trailer into a garage..Diff locked solid about 2km into the test drive, at about 90kph...
Pulled the old diff out, and then pulled it to pieces...
I would say going by the broken bearings floating about, that the pinion bearing was starved of oil, which then ceased, as a result locked the pinion gear solid, but with the rotational force of the crown wheel, then spat the pinion clean in half and out the bottom of the carrier housing.
Wind the clock forward to present...
So the ZZ/R PF60 LSD diff arrived from japan through Ewan @ Hayatonka (very helpful and easy to deal with) finally. Got it home, sat for a couple of weeks till I got enthused enough to do something..
Sent away a pile of bolts, brackets etc to be plated by one Mr Greg Topp!
Came back and I'd assembled the diff with new bushes, painted it with hammerite, swapped calipers, discs, torque tube, brake lines etc all over. Also took the opportunity while the diff was out to underseal the rear guards completely..
