i am getting a few PM's asking me how i get the M05 ball diff so tight and my Experiences with them SO ...........

This is how i got my M05 3Racing ball diff tight as hell and not stripping/snapping screws

I stripped it , sanded the plates added a good amount of asso fat and used a TRF416 bolt , nut and thrust washer

Add extra oil/asso fat to the thrust bearing and extra loctite to the bolt

Tightened it till it was really tight to turn the ball diff outdrives and then stuck it in the M05

Make sure when you fit the diff that the adjuster bolt is on the left side of the car , this i believe stops the bolt loosening

Drive it a few laps and see how tight it is , maybe you can get a little more on the bolt

Can we use back the stock m05 ball-diff thrust washer? I only managed to get the TRF416 bolt & nut.

you can but mine colapsed after 2 runs

Isn't the m05 ball diff thrust bearing the exact same bearing as the one in 416?

@sidecarphil

Are you using a Tamiya M05 ball diff or a 3racing M05 ball dif?

Here is Phil's set up from pg 785.

Started the build on my new m05 today, waiting until tomorrow to finish so I can get the ball diff.

Yes they are the same.



@JustMe2

Just want to clarify as post from others leads me to believe that there is some confusion as to what brand diff is use.
Yes I read 3racing from Phil

Sorry, I wasn't trying to be rude or sarcastic. I wasn't sure Phil's set up had been found. Took me a bit to find it myself. I also asked about his set up for my new m05 as well.

No worries. Its all good. Just want to make sure everyone is on the same page.

it was at one stage a 3Racing ball diff BUT i changed the screw,nut and thrust bearing to TRF416 items and the balls are ceramic soooo it is 50/50 now LOL

really reliable but still not in the car for the 6 hours race we have on sunday (vids and pics to follow)

I have just bought the "Tamiya (#53345) Toe-in Rear Upright For TL-01/M03" and installed them in my M04 VW. But to my dismay the original bearings doesn't fit - they are too small!!

Whats up with that! ?

Well I searched this thread and on page 154 a guy had the same problem, but I couldn't really see which size bearing that will fit from the replies he got back then.

So to my question: Which size bearings should I buy so that it wil fit in my new Uprights (53345)?

Any help will be appreciated.

Cheers,
Peter

You need 5mm x 11mm bearings.

Thanks for your answer.

Is that the ones that Tamiya has named 1150 bearings?

Cheers,
Peter

Yes that is correct.

You are using 2.4mm balls correct?
