SMITTY- Many thanks for your suggestion. I have a good friend in Melbourne checking for me.
.........................
Regarding the Salisbury diff. I've made thrust plates, acquired springs and rebuilt the diff centre with them. I now have 2 driving wheels, result.
In testing it i've determined that I need stronger springs as the LSD breaks at 35 ft/lbs of torque and it should be 50. I think this may lessen as the diff is used and the oil warms.
I could just replace the centre but I have to admit that I find this all very interesting and a bit of a challenge to make it work.
A hint .. maybe on your final comment
When I bought my VK (ex Vicpol as it turned out per the broadcast sheet) it was a LV2 304 carby engine
.. stuffed at 190,000kms, a M21 4 speed with only 1st and reverse and a VERY noisy single spinner 'large Salisbury'3.08 ratio
I rebuilt all but re the diff...yeah, similar problem and I wanted a TIGHT LSD as it was to be used on the race track
torque was too low like you... my solution? DOUBLE springs! Prick of a job to assemble the centre I can tell you but
it really worked well. You do have to grind the ends to fit both.
that is until about 3 years later, entering T1 at Phillip Island... I selected 1st not 3rd. Ouch....
Sure increased the heart rate, spun into the sand on the outside with diff locked but not before I took a tooth
off the pinion and cracked the LSD centre housing.
Fix?
Fitted a spool and NEW 3.36 gears ( I got off a guy selling motorsport stuff in Ballaarat Victoria who also sells rebuild kits)
