Ski Doo Crank Bearing Isoflex Regrease

Hey Everyone, I knew this engine had a top end rebuild about 5K ago or so and i decided it was time for a PTO side Isoflex grease change as this seems to be a common practice. Apparently Ski Doo did this to meet emission standards allowing for less oil to be consumed due to the 2 outer crank bearings not having to be lubricated with Injection oil. In the end this turns into a PITA for the owner but i believe is good precaution to do. The MAG side is not as common of a practice to change because it is not subject to a lot of heat because there is no clutch mounted to it. Hope this helps. Josh

Great video! I just picked up at 800, 2007 Mxz and was advised to check this. I am rebuilding the carbs and then working on this next. It was rebuilt a few years ago but hardly driven. You gave some good tips here about the air vent and the grease coming out. The 4 bolts would have a torque spec on that but not sure, a good rule of thumb is 17 ft lbs for most things that size.

What works good for a clutch holder is a small ratchet strap. My 03 800 has no retainer plate just the seal. They say you need to split the crank case to change it But if you put the seal in the Deep Freezer for two days like I did it shrinks just enough to get it in there without damaging it. Be quick when installing or you will beat up the seal. They say knowledge is gained by making mistakes well I must have lots of it. Lol 😂. Great 👍 vid.

Haha yes the freezer trick really does help. I have never used it on a seal though. Yep you definitely get knowledge from mistakes. I have made a few in my days....

They started using Isoflex way back in 1999 with the first Series III 600 in the Summit. My 2001 800 nonHO had it as of course because it's Series III. Those ones didn't have the seal retaining plate though and I split my cases to re-grease (mostly to replace the PTO seal after the belt failed and wrapped cords around the shaft.....I didn't want to risk the seal being bad and leaning out the engine and also read that removing the seal without splitting the case can damage it. I think the later ones with the retaining plate allowed you to remove the seals without damage which is much better obviously.

@Schneids15 2 жыл бұрын

Yes much better with the retaining plate. Too bad they couldn’t just be like the old ones and have oil go through them. A way better design.

@MrDraftkid Жыл бұрын

Think there's a pacific amount of grease that goes in... The reason for the 10 - 20 MLS is because grease expands with heat and can push the seal out I believe.

@BlueRage 8 ай бұрын

Yes, 20 ML maximum!

@davidbrennan5 7 ай бұрын

their is a small 90 degree pipe with a cap on it that come out of the crank case behind the clutch. You can grease both pto bearings from this location with a syringe and a hose without taking the clutch off. The mag side, you need to remove the recoil/flywheel and take the top and bottom stator bolts out and add grease through the top threads, this will grease the bearings on that side. This should be done every year imho.

I hadn’t. However i ran with the tube on to let grease flow out and push the old crap out the back side of the bearing. Then re capped. If i did it again i would use less. Was just trying to go by ski doo spec. However no issues.
