trf201 shock rebuild.

[guinness]

I rebuild the rear shocks and it seems that they are not really smooth ,they are really stiff,
Same with new rubber rings,
The shocks are the greys ones with the normal silver shaft and for some reasons the Rings assembly combination does not match the one on the manual.
What I got is 2x rubber rings and 2xplastic rings.

I would recommend following Lee's guide on TRF Racing.

Do the plastic rings move freely on the shock shaft? You may need take a reamer to it, just to widen it a little.

Strange to hear as the TRF201 comes with gold shock bodies and shock shafts, did you get it second hand? Follow the manul exactly, maybe you mounted on of the plastic shims (i think the smaller one) in the opposite direction, i think there are 2 white plastic parts. One rod guide and 2 shims. It would be better to buy the Rod guide set and better Orings than the Tamiya ones, the rod guide set allows you to shim the O ring, makeing it smoother or harder just as you like, part number is 53979:

yes the buggy was second hand and came with the grey shocks??
this what i have at moment,there is no space for anything else.

Is it on both shocks, or just one? Also check that the shock shaft, or even the shock body is not bent.

Probably someone has used the gold cylinders on their 511 and sold the 201 with the std cylinders. Nothing wrong with them. The shim set that muratti posts a link to replaces some of what you have. It comes with instructions. Sometimes you need to shave a fraction off the std guides so that it doesn't compress the oring quite so much.

Yea I have had a shock body ever so slightly oval too.
