[@michaelcompton4049]

Yep they don't waste oil , the older ones had oil ports directly into crank journals, now the bearings on the etec is a sealed greased bearing. They don't waste / use anywhere close to the amount of oil they used to . But thanks for the input ! Lol

What about the big crack in the casting outside the bearing 3 o’clock position

[@Buildcultureyoutube]

I believe that’s where the 2 pieces of the case meet. I can see how it can look like a crack now that I look at it lol

[@GWAYGWAY1]

That IS the crankcases face joints. It split horizontally.

[@michaelcompton4049]

That's not a Crack at 3oclock or 9 o'clock lol it's the seam where bottom case meets top case look again !

[@raykultgen3125]

There is isoflex on the mag side also, done thru stator screws, later models have it in the inner bearings as well.

[@Buildcultureyoutube]

Yes forgot to mention that! This side wears faster because of heat

[@draymond5067]

@Build Culture no, PTO side wears faster due to the belt load...most bearing failure on pto side....it's the opposite on seadoo's

[@machine7767]

Do the 850's also need the bearings serviced? If so, how often for a mountain rider vs. a cross country rider?

[@BillNye-bj5vi]

@ no service required on any crank bearings, until you remove crank and check the bearings, if not up to spec you replace the bearings as needed. many many 800 skidoo go well over 10k miles not been touched

[@Junorr500]

Do a leak down test on that seal after you do this. If seal is bad you need to pull motor and pull off bottom of crankcase to properly install a new brand new seal. A new one will not push in without wrecking it.

[@skidooman97]

How do u preform this test @Junorr500. I did this job about 1500miles ago and now i noticed coolant seeping out of bottom end headgasket .

[@Junorr500]

@@skidooman97 leaking coolant is a whole different issue. Sounds like time to tear out motor and do all new gaskets. May as well split bottom end case to reseal it and do oil seals to.

[@Junorr500]

@@skidooman97 to do leak down test you need to pressurize the crank case. I take carbs off and fit a plug with a schrader valve and a gauge threaded into it and clamp it into carb boot. Pressuize it with 10lb is plenty and watch the gauge. If it drops you have a problem. My clutch side crank seal was leaking. Can see it if you use soap and water and spray it on seal where crank comes through. Will make bubbles. To make this work though you need to seal exhaust as well. Remove y pipe and make a cover/gasket for exaust and secure it but bolting y pipe back on.

[@MrNota500]

That makes no sense the seal is in that cap with the four torqs screws. Why would you split the case?

[@johnwythe1409]

Using cleaner and air would work, but I would be concerned about the bearing behind that. Cleaner could get in that and flush out some grease, then how do you get grease back in that bearing. Also I think there is a seal on that bearing as well, depending on the year. Both sides have two outer bearings. I believe the inner bearings have grease as well, but also get oil, may depend on model and year. I have two questions. 1) How much is too much grease, and is there anything wrong with having grease between the two bearings? On the PTO side there is a large gap between the bearings, hardly any on the mag side. 2) I see someone mentioned the two pipes that have plastic caps on them. Where do those pipes go, and what can happen if one of those caps is missing? TIA

[@AndrewDurfee-c6u]

Did you spray the bearing out with cleaner /then air 1st before you put the new grease in or just wipe it out?

[@Buildcultureyoutube]

I just wiped it out. My fear was I didn’t want any of the spray to still be stuck in there and affect lubrication

[@36ELGALAN]

Great video, nice trick with the Syringe

[@xXkillerkidXxXx]

You need the syringe... shop manual even says so, should only have so many ML in the bearing

[@wtfobiden]

Good job

[@olivermeier2949]

They couldn't just run an oil line to the bearing for priority lubrication? After all,it is the crank. Cool engineering BRP.

[@grizzlysounddj]

I believe that's how the 850s are setup.

[@BillNye-bj5vi]

life of the bearing grease.

[@michaelcompton4049]

They don't oil the bearing so it doesn't waste oil ! It's 2stroke don't forget. That's why the 600 etec is awesome. 20,000 km never been touched . Uses very little oil .

[@MrNota500]

@@michaelcompton4049 It's not so they don't waste oil !?! It's because they are direct injection engines, which means the fuel injectors spray right into the combustion camber and not the intake tract. It's not to save oil, it's for emission and fuel economy. With a carb or older efi the fuel/oil goes through the bottom end first then to the top end through transfer ports.

Was worried about it messing with the new lubricant

[@c90adventures]

I can confirm that isoflex grease doesn't dissolve in either brake cleaner or isopropyl alcohol. I did a test by taking some of the old grease and putting it in containers with liquids. The only thing that dissolved it was WD-40. Other solvents I don't have might work as well of course.

[@davidwright1653]

Why not use a solvent or brake clean to remove the old grease from the bearing? Is the Isoflex the manufacturer's recommended grease? Or one you believe is better? The syringe method is very useful, is wearing nitrile gloves and packing the grease with your fingers not as effective? Thank you for this video!

[@Buildcultureyoutube]

Idk it just felt wrong at the time. But others here have said it’s not an issue. Just did what I thought was best. And the syringe seemed like a very effective method to get it all into the crevices and squeeze out as much old brown grease as possible. Worked quite well. As far as I know that exact isoflex grease is exactly what is used from OEM. It is pricey though.

[@davidbrennan5]

There is a 1/4 inch pipe with a red cap on it behind the clutch on the crankcase to grease the pto bearings. Just add some grease every 2000-3000 miles. The other side is much more difficult, you have to take off the recoil pull the flywheel and add grease through the top stator bolt hole after removing one of the bottom stator bolts. That side needs to be greased, but not as often. The best way is to pull the engine and split the cases though.

[@BillNye-bj5vi]
