The setting from the manual is fine

What are the parts numbers of the 3 parts alluminium ackerman ?what car are from ?
Thanx

[Roel]

It's 3 parts that make up the steering assembly.
They fit on several tamiya 4wd buggies, 501\511\503

Don't know where you can actually buy them tho, they are pretty hard to come by.

53971 Steering Arms
53972 Steering Bridge
53973 Steering Base

Stella has only the bridge in stock but not the other pieces
The steering arms are the rarest to find i think.

[SiR_Dave]

Most of the Alloy steering parts have been discontinued and you will only find a few places world wide that have very little stock of the items
Since Tamiya Japan no longer has stock of these items.. you best bet is going to be Tamiya USA for the Steering arms and Base.. the Bridge is sold out..... on eBay has tons of Bridges and Bases F/S.... Just the Arms ..

I have a few of the items.. as spares... just incase ... or if you want to be cheap and don't care.. 3Racing sells the Arms and Bridge as a set.. but it's not as nice as the Tamiya items..and adjustability of the bridge

Finished the build😁
As usual a great plesure to build a tamiya.
But.......come on tamiya ,why supply the kit with crap ball Heads connectors especially when on the rear under the shock tower are difficult To Unscrew if you want change the camber link position! Anyway I change them with the hard hex version of it .

[SiR_Dave]

Looks good!!

Gents

What are the numbers for belts replacement??

Thanks

[SiR_Dave]

Front and Rear Belt set part #
16244030

[jaq]

I know this number...I thought you will know 5 digit number
I cant find them anywere....

[SiR_Dave]

Tamiya has yet to do the 5 digit yet for them.. I still have to order them direct via Tamiya

[guinness]

ok so i got a set of losi wheels.....but it seems that the drive shaft thread is to short and the wheel nut will only screw halfway ?????
any other 12mm brand suggestion?

[abiye]

You'll have to drill ream out the hole on the wheel. It doesn't fit over the axle.

[guinness]

The hole is not the problem ,the length of the hole it is .
Whent down the shop and got a set for ZX5/RB6 will test them once back home.

[guinness]

Is it possible to buy the blue and red dampers springs separately without getting the set ?

[SiR_Dave]

Unfortunately no... you have to buy them as a set

[guinness]

OK thank!
By the way what the best way to setup the belt tensioners ??

[SiR_Dave]

For the ones with the bearings.. I have about 1mm~.05mm of a gap between the belt and the bearing... without it touch is what I tend to set them at

[guinness]

ok this rear seems to fit ok , i assume they are the positive offset one

[SiR_Dave]

Looks like you found a 12mm hex wheel that fits
