800 rmk motor mounts

[ryemleji76]

I have seen and done a lot of damage to sleds in my life but today while enjoying one of the best days this season the engine in my gen 2 800 rmk ripped loose from the mounts and broke the engine limiter off the body. Both front engine mount bolts appear to be broke. Any thoughts on causes would be appreciated> yes I realize the bolts could have just broke but I have two others just like it that have been rode a lot harder than this sled as it is my spare.

clutches fully engaged when landing a jump? usualy breaks the chain but also snaps motor mounts. They go in a cascade also if one goes and you dont notice the others can go all at once.

Never really took a chance with my 01 800. I put both SLP push and pull arms on it when it was pretty new. Never broke a motor mount in 4000mi, but I know it was trying to break 'em, because the SLP parts broke several times (warrantied every time, thanks SLP!).
So, yeah, they're know to be a weak spot, but there are a couple different upgraded mounts (harder duro rubber) and the add on braces as well.

Check clutch balance and crank runout. I bet the damage was starting long before today. Almost always when I see a broken motor mount on a big block 800 it is followed up by a broken crank.

I have seen this twice. both times the front PTO mount was broke, the crank was close to follow.
