RE: melted spur gear
can you tighten your slipper down tight on the X? if you can tighten it down and havent yet, you should try to run one like that just to see.

Last gear i ran lasted about 5-10 min before melting. wasnt driving hard either. could feel heat coming off c/b that when i temped it and it showed 200 on temp gauge.

RE: melted spur gear
Get a set of aluminum clutch shoes. The stockers are slipping and building heat, that in turn warms up the spur gear and softens it enough that the teeth just rip off of it.
Go ahead and get two new sets of clutchbell bearings too. The heat has probably already sent yours on a path to destruction, and you should always keep a spare set on hand.

RE: melted spur gear
The only spur gear I ever had a problem with was when I was breaking in my engine and the CB got hotter then my engine and melted the spur do to the sorry stock clutch shoes slipping. I put alloy clutch shoes in and now in about 3 gallons have not had a problem since.

RE: melted spur gear
The stock shoes are the carbon ones. I'm using Team Losi LST2 shoes and they are fine so far. The shoes, springs, and washers came together for $20 from the LHS and they work with the stock nut.

RE: melted spur gear
I am running Nova alloy shoes with the stock CB but have been told you need to run a harden CB. I have around 3 gallons on mine since I put the alloy shoes in it and I probably need to check the shoes and CB which I have a harden one to put on it now.
Here is a link to Nova.

RE: melted spur gear
I melted my first spur on my 4.6. But after tightening the slipper right up and drilling 6 2mm cooling hols in the end on the clutch bell I've had no problems in 2 gallons.

RE: melted spur gear
Heres one for you guys. I just upgraded my Savage 21 from the 2 shoe clutch to the 3 shoe clutch and Im still melting spurs. is there such a thing as a bad or worn cb? Heck, these BRAND new shoes should not be slipping. my plan is a vented clutchbell and some new bearings. Then if that dont work, I'll go alum. shoes. Sound good? the only reason I dont wqanna do aluminum shoes yet is bc I JUST put these on and not even a tank thourgh it.
