I have an older rc10, appears to have an aftermarket graphite chassis, older 6 gears trans. My question is about the idler, is there a steel one (pair) available? Also, what is the pitch on this gear? It has 22 teeth, seems to be around 36P or .7mod using a formula for pitch I found on the web. I would think it is not 48p, teeth are way too large for that but I saw a recent thread on here talking about a 48p idler. any help?
Thanks

no one makes anything for the 6 gear anymore...... aftermarket anyway. a couple of them did make metal idler gears. i think raceway mfg. was one. good luck finding a pair of them.

the stock gears in a 6 gear were 32 pitch. i haven't looked in awhile, but tower hobbies might still have the black associated ones if you need them.

Thanks, tower (and ebay) have the plastic ones. When I cracked open the trans I was surprised that most of the gears were steel, steel idlers would complete it. But if they are not to be had then so be it.

The combo of metal and steel produced a smoother tranny, which was imperative with the old 6-gears. The metal idlers were hot, back in the day, for about an hour.
First time I ever saw delrin used on an RC was on machined idlers, they were pretty trick.

If it's got white idlers put some new black ones in it makes the transmission as free as a stealth apart from the diff action. They changed the tooth profile it seems.

You've got a pm.

make sure you remove the felt seals and plastic retainer from around the outdrives. put a bearing(same as b4 bearing) in the gear case around the outdrives. this is the biggest improvmest. it keeps everything from wobling and eating idlers.

what is the bearing size for the outdrives?

3/8 x 5/8. Associated PN- 3976. I think. Maybe someone could let use know for sure.

yup, 3/8 x 5/8 plain bearings.

cheapest place for bearings........ $1.00 each.
