TRF511 Upgrade Set (#84315) Parts Availability

[djmcnz]

Update 02 April
So to save others some time I thought I'd summarise my findings having spent a little time on web and phone looking into this.

Problem
I needed individual kit parts from the TRF511 Upgrade Set (#84315), belts and pulleys in my case however this adventure applies to all 1 vehicle parts in the kit (i.e all the bits for this kit alone).

Findings
They're not available from Tamiya Japan. There's no indication that they will be made available in the future but you'd hope it was likely. There has been no mention of a future release which probably means that if they do come it will be August or later.

Apparently there have been similar occurrences in the TC world with the ball diff pulleys being a culprit there too.

On that note it does appear as if the TA06 ball diff pulley (39T) will fit but neither is that available as a single part from Tamiya. The 37T pulley as an individual part evidently arrived some ten or more months after the full assembly!

As a consequence there is an aftermarket for TC pulleys in Japan (and elsewhere I suppose) because apparently the drift guys eat through them, I have no idea.

Reading around (mostly Japanese sites) these are a credible replacement:


Link: Eagle Racing 39T Delrin TA06 Solid/Ball Diff Pulley (DP01-39T)

I can't personally recommend these yet, I've ordered a handful because they're inexpensive and will report back when I get them (and sell some if they're okay).

If you need a new belt, chassis, diff joints, or any of the alloy bits from the set as individual parts then you're stuffed for the time being.

Conclusion
I purchased a handful of aftermarket pulleys (see above) and also a NIP Upgrade Set (thanks Kennith). I'd hate to need another complete set when they're out of stock again and who knows if there'll be another run.

Hey, they may just be withholding individual spares for suckers like me but it's a PITA!

Hope that helps someone,

Dave

Hi there,

I need new pulleys and belts for my 511 w/upgrade kit, has anybody had success sourcing them? (Warning: don't use aftermarket diff covers with the 39T pulleys, insufficient clearance if something does get in).

I've tried my usual TRF stockist in Germany and they say the part numbers (8 digit from the Upgrade Kit manual) are not listed on the Tamiya Japan dealers site. They've never had a problem supplying me hard-to-find TRF parts in the past.

It's a pretty useless upgrade it we can't get spares. I'm on the verge of buying another complete kit just to secure the parts which would sort-of suck.

Any suggestions?

Cheers.
