Fg marder & monster spur gears

[templ8]

Having stripped another plastic spur gear on my fg monster, and finding that there's no uk stock of single speed 46t gears, are the fg steel gears worth the extra money ?

There's nothing wrong with the mesh, it's perfect, just seems to strip the spur after a good half hour of running when everything is hot. The steel pinion gets up to 70 degrees Celsius on occasion, maybe this is softening the plastic ?

Maybe it's my driving, the spurs strip usually after the rear gets airborne on a flat out run.

Planning a trip to rossmod tomorrow for some parts.

If you have plastic diff and engine mounts, change them ASAP.
Some have few/no problems, but most start stripping the gears through the flex.

Also consider changing the plastic gear mount for alloy, if you have plastic.

Blackbone are spot on.
Check the fit on your drives - if you have any tuning shafts, the flats - where the grub goes - are not opposite each other, as the Blackbone requires, but are at 90 degrees.

Thanks for the replies

I have alloy mounts but a plastic gear carrier, looking to change that.

The layshaft has 90 degree flats, will probably go for the genuine fg steel gear and carrier.

I haven't had the pot off the engine yet (g260rc) but I reckon it might have internal mods, it's as fast as my mates marder with an alro 29cc motor and dominator pipe

You're welcome mate.
We're all in this 'together'.

'K' - we know all of yours have silver plated chrome-moly-vanadium parts and are planted on a plinth above the fireplace!!

I went through two lots of plastic gears before changing to black bone I was reluctant at first but glad I did there well worth the money!!!!

My gear issue seems to be from the spur hitting the rear suspension or dog bone,you may think there is enuogh clearance but under compression of rear suspension(like landing from a big jump) the spur will drag and shear the spur.

have you got alloy upper rear arms mate they will stop most of that but id still go for metal gears for off roading
