Average miles till rebuild?

[Publiconion]

I have an 11-800 pTek that I love. Rock solid but want to keep it that way.
What's the general recomendations for miles till rebuild?

I would do it about 50 miles before she blows.


Sorry, I don't know how far that is in "metric miles".

I did our 2010's at about 3800. I pull the raves once in a while and keep an eye on how the piston skirt and rings are looking. Do top end when it starts scuffing. My 2c.

If its all mountain miles, I would say 2000-2500 to be safe. It really depends a lot on how you ride and maintain.

mine let loose at 4000 k
rod bearing went and took out the case

Thanks for the feedback. I'll probably tear her down this summer and do some measurements. Top end is much cheaper than a heli ride so will probably do that regardless. Cheers.

It all depends how you ride and use your sled ... It very simple to check compression and go from there.

dont forget to isoflex those bearings in the lower end

Rebuild

Snowmobile engines are rated for 300 hours before a major overhaul. Miles are just a function of average land speed.

Good point. I'll start a log keeping track of where the compression is at. Thanks.
