I just finished my M05 pro build,,used the siler grease that came with the kit for the diff,feels kind of tight,under hard acceleration,the car seems to pull very hard to one side,is this because of the stiff grease,should I disassemble and put something lighter in?

Craig J,

Which 'O" ring did you use in the diff cups? I do not use the black 'o" ring but use the white silicon ones. Have you fitted universals to the front?

Some use spools in the MO5, without this problem.

i used REALLY REALLY thick grease in my diff and had no pulling problems

BUT when it was new it pulled like a bitch to the right side under accelaration , i think it was the rubber O rings in the diff halfs that did it

i am using a set of the Tamiya universal drive shafts and now got the 3Racing ball diff to try out , still pulls as straight as an arrow

I am using the Tamiya universals and the new Tamiya MO5 ball diff with great success. As I said I use the Tamiya clear silicon "o " rings in my diff cups. Pulls straight. No problems.

I will only use a TAO3 ball diff in my MO3 now. The new ball diff is just so much better and easily adjusted on the MO5.

Later,

i decided not to buy the Tamiya ball diff as it is SERIOUSLY expensave and i am impressed with the quality of the 3Racing F1-09 so i decided on that , it is the same looking as the Tamiya one but no silly outdrive protectors for the universals !!

it is adjustable from outside the chassis too , the only thing i am a little dissapointed about is the speed gears , i think they dont mesh propperly

The speed gear set is useless. They bind

As for the 3 racing ball diff, it depoends on whether you get the steel outdrives or alloy. Alloy has blades for the universals .. the steel doesn't.
The ball diffs from 3 Racing are good but are let down by their hardware ...thrust bearings, bolt and nut . Very poor quality which causes failure

sidecarphil1,

I have used both the 3Racing MO5 ball diff with the alloy cups and the Tamiya MO5 ball diff. I found that the 3Racing ball dff when tightened so it did not slip, stripped the 2mm lock nut and screw. I also noticed that the thrust bearing was not as good as the Tamiya one piece offering. I rebuilt my MO5 3Racing ball diff with a Tamiya thrust bearing, new 2mm diff screw and a new 2mm locknut and yes it works fine, however it is assigned to my spares box.

The Tamiya unit is so much better. I replaced the steel balls with the 3mm carbide balls and packed it with anti-ware grease. I purchased mine from Japan and was happy with the price. It will stay in my car until it needs a rebuild or I break it. I am still using the blades from the 3Racing diff on my universals in the Tamiya diff. They do not appear to have any wear marks, even after the thrashing I have subjected them too.

As they say in the classics, "You get what you pay for".

The same could be said for the Tamiya alloy steering linkage, however I think it works better than some of the others due to its horseshoe shape.

Just my two cents worth. Each to their own.

Regards,

Calvin.

i got the one with the steel outdrives

i will do as i do with all my ball diffs , strip , rebuild with some asso fat

i have spares from my busted TA05 diffs and the TRF diffs i have spares i will use a propper tamiya bolt and nut

see what i think and it will be crash/race tested

race/crash testing is always the biggest leveller of all.

3 racing ball diffs are more expensive than the Tamiya's in the sense they break easily. these types of poor quality products should not even be sold in the first place. crushed thrust bearings. loosening diffs.

it is light though at 17 grams.

You can strip the screw in the Tamiya MO5 ball diff also, just takes more effort. So I am told. Bit of a bugger to get apart. Takes at least two people to sort it out. Must of happened at the Hill.

Sorry, do you mean the Xevo only uses 1150's or the M05 diff only uses 1150's

I'm guessing you mean the Xevo is on 1150's so that would mean the M05 diff is on something else? Does it have outdrive adaptors then, as the M05 stock diff is exactly the same as an M03's isn't it. Would I be correct assuming this means I can't use the M05 ball diff in my M03 too?

Thanks for all the advice guys,seems I have some spare clear o-rings left and will give those a shot,and maybe even a set of universals.

when building the trf m-chassis shocks how many o-rings should i put on the inside shaft? it says 1, but im thinking 2
