Marder problem

[rc-martin]

Apart from the usual problems of the things just falling to pieces, my Marder also has a taste for eating spur gears, in the nine or so months i've had it it has chewed about eight of them up!! [!]

The car has a gearcover fitted to keep the stones out, it has a steel pinion, cos the plastic one only lasted five minutes! And i've also changed the spur gear adaptor for an alloy version. The gear mesh between the two gears is good, with ample but not to much backlash but after running it for about ten minutes it just metls the teeth on the spur gear and sits there revving its t#ts off!

Any ideas?

Seems my problem lies in the steel pinion transfering heat from the clutch bell. After a while the pinion gets so hot it melts the teeth on the spur gear.

Just need to find a way to keep the clutch bell cool now. [?]

Hi Martin,

The only think I can suggest is getting a spur gear made out of Metal or perhaps Tufnol is worth looking at. You'd be hard pushed to knacker/melt that and if you advertise it a bit might get your Money back on the tooling/manuf. costs by selling a few as I expect it's a common problem.

Unless you're playing with it in your bedroom, I don't thing the clutch should get that hot.. !!!

I'd see if the shoes are binding first and that the bell is aligned properly... Is the bell bearing (into the gear carrier) clean and free running..??

Also have you tried the "bit of paper between the teeth" method of adjustment..??
