stripping spur gears

[savvy25]

Ok, a co-worker of mine has a savage 25 with the stock motor in it. Every time we go bashing he strips his spur gear. He has the 3 speed tranny in it. Ive tried to set this thing up 3 times. I use the paper method, same as I did in mine. I have no trouble with mine. His cb is a 17 and a 47 spur gear, we've also tried a 49 spur gear. Any ideas?

Check for engine movement and or a cracked motor plate.

Like piney said check for engine movement, tranny movement, cracked AND/OR bent motor plate.

don't for get to locktite the the screws holding the engine to the motor plate if they are loose.

look at the motor mount and engine plat also see if he has the slipper to tight or maybe go to metal

I assume steel spur and cb? How much run time on this truck prior to problem?

and don't forget the old fall back reason...make sure he's not holding the throttle wide open when landing jumps, or taking hard jolts...nothing demolishes spur gears faster in my opinion...

I agree with komodo. Check the slipper too, make sure its not set too tight or too loose.

Check the transmission's top shaft, the one to which the spur is mounted. Make sure it's not bent.

Thanks for the input. We will check all that stuff out. The truck is new to him, got it off ebay. He's addicted.

check the cb bearings if they are worn they will heat up the cb and melt the spur also check the clutches. if these 2 things are bad it over heats the cb bad.
