Crushable spacers for diff pinion.
I am looking into changing a diff drive flange on an english axle with a crushable spacer. The spacers do not seem to be available and i have been
told that the only option is to reuse the spacer and carefully adjust the preload to the original.
I have been thinking of turning up a solid spacer that is overlength and then set up the pinion shaft and measuring the endfloat witha dial gauge, and
adjusting the preload by machining the spacer to suit.
Has anyone else faced the same problem ? or is it possible to buy the crushable tube somewhere.

In the time i worked for a ford main dealer it was the norm to mark the nut and refit in the same place once you had done what ever (change the seal
etc).

I considered this but as i will be changing the flange i am not certain it would be correct unless the flanges are identical.

Hi paulf, i was in the same position as you could,nt get hold of factory crushable spacers. so i did exactly what you are considering to do, i made a
spacer slightly over size then using a dial indicator fixed to the diff housing i measured the total end float , then worked out the spacer length to
give zero end float and then machined off two thousandths to give the correct two thou pre load to the taper roller bearings. cheers davef.

Thanks for the info , that is the way i will tackle it i wasnt sure of how much extra preload to give it.
All i need to do now is find a drive flange.

Give the spread bit a few taps with the fitting stick and you will have streached out your old spacer. You can then set the preload as specified. If
you get it wrong and go too far you have to take it all appart and start again.
If you are putting a lot of power through the axle and intending to do track work, set the diff a bit loose so that it doesn't generate so much
heat.
