Make sure you get real isoflex from a dealer. There's tons of imitation crap labeled as iso but its not the same & will cause issues. Have a helper turn the engine over by hand (plug wires removed) as you do the mag side it will help get it spread through more evenly. Just 1 slow rotation as you squeeze in the isoflex. Thank you for stopping by the channel & happy riding this yr man👊 hopefully we get some major snow🙏🙏
Thanks for the clear explanation. I'm also servicing an 800r I just don't see the access nipple on these blocks. Only have 4 ports on carb side of motor. 2 oil and 2 air pulse lines. Great trick with the ziptie and rotating motor to check for access to bearing.
R is the same thing. You can also buy the “grease buddy” for the Mag and PTO side. It goes on the tube you showed on the PTO side and a bolt with a hole in the mag side. Then you can grease them with ease.
Do you pull your seal off before you add the grease so that the pressure from pushing it in has a place to go? I’ve heard about the inner seal for the outer bearings could blow out. I’m about to grease my bearings on a rev 500, and was just curious if I had to worry. Basically I’m wondering if I’m able to just put the grease through that port you show, while turning over the motor slowly, with the seal on
No concerns unless you put too much in there. Dont force it go slow & slowly rotate as you said. Keep the isoflex inside/warm it will make things much easier. If your concerned put in half what they recommend go on a good ride then add 2nd half👍 Ppl that just force it in quickly or use too much can definitely push it past the seal & cause major issues. Follow the guidelines you'll be good to go. Now if your super fussy & have no problem yanking the clutch then sure drive a acrew into the seal pull it wipe out all old grease then do it from that end & replace the seal. But again dont overdue it or when you go to seat the new seal hydraulic pressure will blow the inner seal out as your saying. Sounds like you have a good idea about it all so i would suggest doing whichever way you feel most comfortable with👊 Thanks for stopping by the channel & happy trails my friend.
@@thegreatgreennorth9983what about injecting half of grease slowly into the nipple side with the seal off (while turning motor slowly), and then the other half putting into the face of the outer bearing (once the old grease is all wiped away). At same time, it replaces the old seal that can potentially leak air and blow the motor. Also, I wonder why they didn’t add a nipple to the MAG side? Is it because there’s only one bearing on mag side?
@@kjellamundsen1463 Yes im pretty sure it does. If its the same looking setup deffinatly. You want pay xtra close attention to those bearings i inspect before every ride. Pto/clutch side watch for any grease/oil leaking behind the clutch. Mag sides little more of a pain you need to pull the recoil to visually inspect that side. And keep in mind this is only outer seal inspection there's no way to tell if the inners are seeping besides watching for the excessive smoke on start up especially 1st start of the season. Make sure you dont over grease them too be careful dont force it in and blow that inner seal out. Even adding a 1/4 of whats recommended a couple times a season would be good insurance without the risk of over doing it. I have no clue how capable you are mechanicaly so im trying to steer you right on this👊 If your unsure of anything dig into it research it hard ask questions make darn sure you understand before doing anything. Good luck & have a safe season man👊
@@Betterthanbought. thanks I appreciate your respons. I am capable and will get on with it before the season for peace of mind I guess. Mine have run about 5000km /3500 miles but I know bearings have never been greased up since new. Also being a 2008 the grease will probaby dry out from aging alone.
@@kjellamundsen1463 No problem man. Make sure you get the isoflex from a dealer too. Most the stuff on e ba y & such is just white lithium its a huge scam with that stuff🤦♂️. I think i would find out how much they recommend to put for your year & i would do half of it. Ride half the season then do the 2nd half then. Just to be easy on everything no pressure on those inner seals ect. Little xtra work but i would think of it as insurance.
No isoflex doesn't reach the inner bearings ever those 2 are oil bathed. Please watch the video you will see how there all seperate. Pto and mag sides get isoflex only. The inners get bathed in 2 stroke oil constantly. Hence why those rarely fail. Using more isoflex than is recommended can damage the inner seal for outer bearings by creating hydraulic pressure just dont overdue it theres clear amounts specified for each yr/model simply follow that & your good to go👍 also make sure your buying real isoflex from a (dealer only) Hope that helps clear things up👊
@@thegreatgreennorth9983 Great explanation about the outer bearings. The 2 center bearings aren't in an oil bath, they are lubed from the oil injection. Only the water pump/oil pump gear/bearings are in an oil bath. Check out a shop manual and you'll see that they spec to add 50ml of oil to that cavity when assembling the engine. Also if you look closer at the crank in the video, you can see where the red center seals are located. They're on the wrong side of the bearing if they're meant to keep the bearing in an oil bath.
Does anybody know the correct amount for the PTO side? I just rebuilt the lower end but I had a hard time getting the inner pto bearing. So I have a little bit of Isoflex left over that I’d like to inject in.
10-15 ml is what it is said to be correct for a refill on the pto side. Ive done 10ml without any problems. Just dont overdue it or force it in otherwise you risk blowing out the seal. Good luck.
Great job explaining! I have an 800r and will be doing isoflex soon. Thx so much. You're a great teacher!!!

Anytime man. Just realized i responded from my other account my bad. Happy Holidays to you & yours my friend.

Thx for making this video.
Super good info. Thanks a lot
Great video thank you
So do you have to do this on the 08 800r

Does this apply to the 800r 2008 as well?

Would this same theory also work for 2003 600ho/800 motors?
Yes
Nice veido
Doing this can blow the inner seals, cant it? The middle red ones
