Wonder if doo tosses the good old white governor gear in there to see if it browns from excessive heat like most mfg's do.. Exactly, and what the dealer pointed out.

First time I put a load on the motor (the field 2 weeks later) it let go. I really dont care what happened, I have a warranty and insurance. One of them should cover it. A simple low speed rollover shouldnt destroy a 15,000 dollar sled. He didn’t elaborate on how the rollover could have caused it? Quote Link to comment Share on other sites More sharing options...

It was good you told him it was on its roof the , This would have been my first thing to go to, and if you had just said "i was riding along as normal and boom" I would say, no warranty for you you ran it out of oil.. 1 Quote Link to comment Share on other sites More sharing options...

s pump Posted February 17, 2020 Share Posted February 17, 2020 8 minutes ago, washedupmxer said: I didn't think he was right either but you can't tell him anything Imo hydro lock slightly bent rod would cause hardcore ejection at high rpm more than low oil seizure I'm thinking it somehow got hydro locked. It was locked up solid and probably bent a rod. I can't believe it would get oil starved in 10 seconds. Ive seen videos of engines running with no oil for long periods at high rpm. 10 seconds won't wash out the oil imo. 1 Quote Link to comment Share on other sites More sharing options...

They are designed to shut down immediately upon low oil pressure though. To have cooked that bearing and journal to the point it blued would have taken some time without oil , like many seconds I’d guess. My gut says there was an issue with this motor all along 2 Quote Link to comment Share on other sites More sharing options...

It was running when woolie shut it down. There is no way to hydro lock that motor like a wet sump would. The oil can’t “leak” up into the cylinders in any significant amount especially when it’s running Quote Link to comment Share on other sites More sharing options...

But that was more than just the engine. The mag side DI was almost $500 and reeds were anorher $200. IIRC, the engine was close to $4,200. But yea, that $5,1?? wasn't including labor.

Yes,the oil pump was pumping away while it was upside down. Any gravity oil return would pocket oil in places it shouldn’t be. Quote Link to comment Share on other sites More sharing options...

Very little oil in the system, whatever pooled in the head could have ran down into a cylinder that had an open valve 1 Quote Link to comment Share on other sites More sharing options...
Frostynuts Posted February 17, 2020 Share Posted February 17, 2020 It,s to bad all sleds didn,t come equipped with an engine kill switch that is attached to a tether cord and your coat. Might have killed the sled engine quik enough that oil starvation wouldn,t have ruined the engine. Might be a great idea for all non trail riders to add one to their sleds.

Ski Doos all come factory with a tether. Running the motor WFO upside down for 10 seconds is one of the many reasons I wear one all the time. Sucks to see any machine down during the season, especially a new one. Hopefully Drifabusta gets it fixed quick and with minimal hassle from Ski Doo. Be interesting to hear why it went down. Certainly being hydrolocked was part of it. 1 Quote Link to comment Share on other sites More sharing options...

True, i probably should have been tethered. That said, Polaris doesnt even come with a tether, so its not like its a universally accepted safety precaution. We were just plonking along in some wormholes, i wasnt going more than 5 mph when it rolled. Quote Link to comment Share on other sites More sharing options...

1jkw Posted February 17, 2020 Share Posted February 17, 2020 Maybe an inertia switch to shut it down when upside down, like they have for car fuel pumps. Quote Link to comment Share on other sites More sharing options...

Case in point. Drop the thing off in the middle of riding season, when the service work is backed up a couple weeks out, and their service mgr who Im friends with texts me the issue about an hour later. 2 Quote Link to comment Share on other sites More sharing options...

Your situation is a strange one Agreed, and when i bogged Sat coming across the field the first time i thought. (Hoped) maybe it was just sucking some of that oil into the injectors. Still dont know what that was cuz it seemed to perk right back up and run fine. In hindsight I think it was a rod or crank bearing seizing up 1 Quote Link to comment Share on other sites More sharing options...
