Wraith transmission change?

[uk-Pedro]

Hi,

My Poison Spider Wraith has pretty much sat on a shelf for the longest time, recently I took it out and chewed up the spur gear and now can't find a replacement - do I need to change the tranny to something more common?

I used to use Robinson Racing Supertuff Spur Gears (80 Tooth, 48 Pitch) but stock of these seems to have dried up.

What is everyone else using?

Cheers,
Pedro

Problem is you need new friction plates and pads and I am struggling to find them now...they look something like this...

the 48p gears suck you need 32p pinnion and spur gear and dont worrie about the clutch pads just lock it out or buy a slipper eliminator ive always locked my slippers from day 1 i see non reason for a clutch
and if youndont have the metal gears inside the trans you should make that upgrade while your in there the little middle gear likes to poop the bed

Yes, I lock my slipper clutch normally.
And I was running the Wraith Spawn gear but can’t find spares anywhere.
I wouldn’t mind changing to 32dp gear as I have all steel gearbox internals already.

Could someone suggest which 32dp spur and pinion to buy please?
Cheers

the wraith spawn used 32p gears from the factory so if you already converted to spawn parts you should already have the right pinnion

heres the stock spur gear

there are alot of aftermarket gears too and it dosent matter so much what brand the gear is made for as long as the pitch and teeth are right
stock is 56t if i remeber right you can go up to 60 teeth with out it hitting the drive shaft but your gear cover might not fit

Ahh, my bad. I meant I’m running the Poison Spider gear, not Spawn.

Thanks for the help. I’ll get some Spawn spur and pinions.

the stock spawn pinion was 15t i would go down to a 14 tooth or even a 13t 32p gearset
the stock wraith gearing is a bit high and has a tendency to smoke the motor when doing hard crawls


you should have a single disk slipper clutch on that that bolts the clutch plate to the gear

so any 32p spur with the holes in it will work fine the spawn spur has the holes predrilled so it should work just fine for you
