put a large washer on top of the spring then reassemble. remember to clean the shims well before reassembly.

This info is from an old Forum .
8" Diff breakaway is much the same as the 9.25" Diff

From memory the 9 1/4" diff , standard, has a breakaway of 70 to 90Ft Lbs. By trying differant thicknes's shimms you will reach tour required target. Go no more than 1/2mm at a time ,
I have got an old axle, cut it off to 6" long(splined end) and welded an old 1/2" socket to it , fit it into your diff side gear, then install your touque wrench, fit another old axle to the other side, which is held in the vice.
NOTE Breakaway or cracking , is the energy level to start the movement of turning the axle.Which is far greater than the flowing resistance.

I don't do washers.... I've got a slippery housing here where an idiot did this and got it wrong and it has blown one end of the housing out :roll: I clean off the packs stack them up and measure the thickness (measurement is in the hane's manual) and then cut shim steel to make it back out to the tight side of the measurement, drop these under the first drive plate, sit's in the bottom of the housing and reasemble.... remember to turn your spring retainer in the centre so its lined up right... seen a few broken ones from this
I don't do oldblues trick.... in fact its the right way to do it its just I don't have a jig like he's got, one day when I've got some spare bits 8)
