How to lube jackshaft bearing on '09 Dragon

nine lives · Mar 21, 2009

I just bought a used 2009 Dragon RMK. There is a label and also a note in the owner's manual to lube the jackshaft every 1000 miles. Does anyone know if you have to pull the airbox to lube it?? There is not a fitting on the flange behind the driven clutch. Any help would be great.

MY 08 has a zert below the secondary. look directly below the bottom of the sheave of the secondary clutch on the top of the speedo sensor housing. 2 pumps..no more than 4 on the greesegun. Very tricky these Polaris Cad drawing engineers.

BTW...you can download a owners manual from the Polaris web site for free.

Did you mean the Jackshaft or the Driveshaft?

Driveshaft bearing is not a sealed bearing and needs to be greased as stated above by a zerk located by the speedo sensor. The Jackshaft bearing which is located directly behind the secondary is a double sealed bearing which you cannot grease.

Deepdiver and Nelson -- thanks for the info. I have found and lubed the driveshaft bearing, no problem there. I was referring to the jackshaft bearing that I could not find a fitting for. If it is sealed, I won't worry about it. Thanks for the input.

If you put on more than 1500 miles... I'd replace that sukker for good insurance at the end of the season... Just my 2 cents.

If you think about it... all the HP your sled makes is supported by this little bearing that is not lube-able....

The older sleds had lower HP numbers stock AND they had a bearing you could lube... the new sleds have a lot more HP. Replace that sukka for the cost and headache avoidance if you are a hard core user of the HP your sled makes... mountain sleds are under more of a constant load than trail riders.

MH makes a very good point. Just because it's sealed doesn't mean it's good for life. All bearings wear out and there is a considerable amount of force and load on that bearing.

You can pop the seals out with a pick & put fresh grease in

grease

I believe the edge chassis had a pin hole in the flange that lined up with a similar hole in the bearing race. You pulled the secondary off and used a needle attachment on your grease gun to lube it. I looked at a newer one with the same label and no pin hole. Yours is likely the same way so you will need to pop the seal to lube it.
