sure, I should have my new orion's by then . The hard part will be to get dave to run lol. If we go back to the old larger layout I am totally down. Not sure about this current layout, its pretty small.

I've found that when I get a notchy feeling diff its usually associated with the thrust bearing and washers. Upon invetigating the thrust washers there always seems to be a small pit right in the grove which the captured balls run in, sometimes so minute that the only way to see/feel it is running a needle point in the grove. So my question is do you prep the thrust washers as well as the diff rings? I bought a 3R diff tool for sanding the diff rings and it looks like it also has a capture part to do the thrust washers too.

NB. One thin to note, is that the 2 thrust washers have two different inner hole diameters and go togeather in a specific order. Alot of people just assume they are the same washers.

I haven't tried to resurface the thrust washers, Problem being they are spec'ed out to be 3.5mm thick to locate the screw hole properly. I got some shims to try this with some old parts I kept to test this. But for the first servicing I just flip the washer and use the other side.

The inner diameter of the outboard thrust bearing washer is 3.0mm (if memory serves me correctly) and the other is 3.2mm. the larger Inner diameter washer goes away from the screw head(correct orientation is towards the center of the diff)..

yup but you don't need to buy a special tool! just use the one half of the diff and 1000 grit paper. get the sand paper wet with motor spray and make figure eights with the rings until you see the surface change color/shine. make sure to spray down the rings, diff balls and diff halfs well.

for fluids - the black associated or losi grease works great on the thrust and associated stealth is the best for the diff balls.

usually when the diff feels bad the problem is the trust bearing. after attempting to rebuild the diff w/ fluids your best bet is to replace the thrust. Paul L says he replaces thrusts about 7 times as frequent as he replaces the diff balls and rings.

A little trick I learned after sanding my fingertips off a couple of times....Use a pink eraser to hold the ring rather than your fingertips, it works great. I use 1500 grit on one side and 80 grit on the other. The rough side grips the out drive hub a little better and allows me to run the diff loser without the rings slipping.

tighten your diff slowly. if it isn't in the car yet you can work it in for a few minutes, slowly tightening it. i only make my diff tight enough so that it doesn't slip under max accel. the looser the diff the more your car will rotate.

Im after some advice on going to a new track. I run a pretty large technical asphalt track and my car is set up pretty nice. I'm going to a big meet at a similar surfaced track but its a lot smaller and less technical. Times running 15.5 vs 23.3 second laps. So,

Do you run the car as is and adjust the set up to suit?
Or take the car back to box set up and work a new set up from their? I have around 8 practice runs to get the car ready for qualifying but will need some later ones for the Tekin. Any advice appreciated. Regards, Benzaah.

How often should the cone washers in the diffs be replaced?

With as fast as you go through cars, they should be good for life.

In reality, it probably depends on how tight you make your diffs. But, you can always tighten them down a little more if the washers start to lose their "spring". Not sure how you'd measure this, though.
