That'll be cool

Is this the only size that will fit? Dont suppose you know if any metric size will fit?

I don't find anything wrong with the current orings on the idler gear for the buggy.

[craigosh]

Could you use a tiny zip-tie round the groove instead? though i guess not enough clearence!

I got a 7/16 clip like Raul said as a precaution. Upon installing it I found that it was loose fitting and there was a gap at the open end that looked like the pin can still come out. The pins felt snug in there and the oring looked fine and didn't seem too soft so back on it went. I'm going to the hardware store and am gonna pick up some other orings. Maybe I can find some that aren't as soft? Don't find anything wrong with the current ones though.

What motor are you running, I'm running 7.5 23/78 gearing. Since using retaining compound on the pins I have had no issues. I gave the car about an hour of track time yesterday and upon inspection found one o ring destroyed but the pin well and truly in place. transmission is really smooth too.

What compound did you use?

I think it may only be affecting those that are running 7.5 and 6.5 motors? I'm running an 8.5

I ran a few packs in front of my house with a 9.5. Giving it full throttle blasts and hard braking on high grip asphalt....I hate traction rolling. Purposely did this after readjusting the diff after it slipped and putting the orings back on.

I'm running 6.5 in mine, and have had no issues at all - built as kit.

Loctite retaining compound 648

[Albertini]

Took a look at my gearbox today after a practice on Sunday of 3-4 practice packs and one of the o-rings holding the pin in place is pushed right up and has been rubbing on something. (Running an 8.5 by the way)
The o-rings still in one piece, just, but I reckon one more run would have finished it off.
Still got a tight spot, still got a gap in the gearbox housings, will new housings fix this now? Was it a snag with the first housings only?

I don't mind buying some more housings if they'll cure the issue and I guess I'll just loctite the pins in place. ( But hey, I'd rather be sent them for free)

I'm not whinging, I love this car, I just want to put right some of its snags.

[fastinfastout]

what if you double up on the oring?

[lochness42]

dont think that is possible with the schumachers cvd's design

[JustARcFan]

Did a test today with the pins glued and everything is perfect.

Smooth diff and gearbox

Aren't we talking about layshaft? I mean use heatshrink instead of o-ring on pin, or under o-ring.
And of course this won't work on schueys dogbones, that's something that you can use only on CVDs or double joint CVDs

11mm, fraction smaller than7/16" which could be a good thing if you plan to go this route.

[mikeyscott]

Noticed that people are putting grease on the gears (gear grease) could this also be causing probs?

[slow bob]

i dont think the gear grease would be a problem as my o rings have disintagrated and i havent used the grease

if your o rings havent gone yet you need to glue your pins in or find some other way to retain the pins as the o rings will fail eventualy ..
