Okay, okay, it's no secret, the latest Tamiya shocks seem to leak. Let's have a thread about it!
I got some Much-More silcone o-rings (MK-R02 - 40deg?), and the 'ole in 'em is significantly smaller than the 'ole in the old Tamiya ones that came out of the shock.
I'm sure Ed's tried this already tho, with no luck, and then he was trying 2 o-rings (but 2 is slightly shorted than one and the spacer), will it work?
I have read on t'web somewhere that the off-road boys are replacing the long Tamiya shock shafts with Yokomo ones with some success, maybe the new gold shafts are rubbish, the coating does seem keen to fall off!

Mark, Ed, Ian and me are all experiencing leaking shocks with the latest Tamiya TRFs. I doubt it's anything to do with how we build them!
IFS wont leak as much cos they are upside down and inside the car protected from dirt?

Never known a touring car shock NOT to leak to be honest

Oh we mean excessive leaking, like they don't last a meeting...

Well i cant see that them being laid down would affect them leaking, there still working. Must be a faulty batch of them mine have never really leaked tbh, but i rebuild shocks every 1 or 2 meeting anyway.

Well cos they are laid down and inside the car they'll be more protected from the dirt and grit, so are less likely to wear, I reckon anyway.
Can't be a faulty batch, we didn't all buy them at the same time!
Do you replace o-rings every couple of meetings?

Yeah you'd think there more protected but there not really, they still get dirty. i have never relpaced any of the parts on them apart from the foam bushing when i gets worn and goes small. I put shock oil on the rubber o-ring inside the bottom cyclinder between the plastic 'ring part. and also on the shock shaft when that is put through the cylinder, just built as per the instructions bascially.
Make sure none of the pistons or the plastic part inside the top of the cap (where the shock pops onto the ball stud) hasnt got a flat where it has been cut off the plastic sheet thing with all the other bits.

Having spoken to a number of other TRF drivers (some on the continent too...), we're not the only ones whove had this. As for the double O-rings, yup thats what I'm running, however, to make up the difference and to try and help them seal against the shaft better, I have a 0.5mm shim in there too. This compresses the o-rings down slightly, compressing them, and pressing against the shaft. On the couple of runs from last week, certainly reduced the amount of leaking, if not fully eleminated it... need to do a whole meeting on this setup first though. As for why the latest leak, not entirely sure. I do have one set of shocks in which the delrin spacer in the bottom is a completely different size, being narrower in diameter so it moves around in the bottom, but also slightly taller... which is very odd. However, another set of the black coated shocks I have in my box have the old style spacers, and they leak as well... tbh, I'm getting used to having to quickly top them up every meeting  As for the shafts, well it certainly seems the coating is no where near as good as it used too be, as it does wear off quite quickly.... actually that gives me a thought. If the coating is thinner.. then it maybe part of the reason for the leaking... hmmm, might try the shocks with old teflon shafts in at some point. Oh, and btw, it's not just the TRF's that have suddenly started doing it... seems the latest batch of shocks with the Cyclone TC do the same thing... go figure... |
