For such small parts, I would try the trick I used to do on some of lab machinery and use a high power soldering iron applied directly to the aluminium. Keep in mind it might affect the anodising colour. I used to take interference fit pinions off motor drives like that. I guess anything that will heat rapidly and locally is good (with variables).

These days, I would try the freeze and release agent first though. That is also a lubricant. I have had some brilliant results pulling sheared studs out of engine blocks I would have just scrapped in the past.

I don't have experience with a 13.5 motor but on my 17.5 motor im running 3k diff oil on a carpet track. I've tried 7k and the rear just washes out on power exiting a turn. I've talked to many people they run 3k at my local track.

Interesting. Alot less mass and less contact patch for the belt. Should help stock classes.

I think the main benefit will be keeping the pinion/spur sizes to planetary dimensions rather than intergalactic.

Thanks, Dawgmeat, that's quite a difference. Might even help me resurrect my old YR4!

As I said earlier, the FDR didn't change so we will all be using the same pinions and spurs,

With a smaller pulley the belts are bent more and you may also have to run your belts tighter to avoid skipping, so I would say it's quite the opposite.

I see no talk of driveshaft/ bone angle with these new diffs position. Anyone has relevant info on the subject?

niznai

True, but you can run the older 20 tooth centre to bring down the ratio.

If you feel the need you can try with yours I guess, looks like it would be a tight fit though ?

If the Center pulley remained the same then the FDR will change

niznai

If the motor mount is the same, it will take the 20 tooth pulley easily, after all that's how it came back whenever it was invented. But I was thinking of getting the new diffs to use in my old car to lower the ratio, that's why I confused people.

Skiddins

If the centre pulley remains the same, but the pulleys change, then different belts will be required as well.

Skiddins

I think that picture of the new and old pulleys has been manipulated a little as well, to exaggerate the difference between them.
The old Xray pulleys were 34t as well, towards the end of the T2's lifetime, and I don't recall there being that much difference in diameter

niznai

I have an entire collection I acquired when doing such modifications to my cars to allow me to change the internal ratio. Xray for instance has belts almost at every length you want around the right size (one tooth increments). You can find them on the Xray website in the parts section. There's also a website with the lengths of all the belts available (new or old) on a drifting forum, if I remember correctly.
