Video on greasing rear needle bearing

[mo8414]

Yeah, seems like it might be an idea to buy a few seals. How much can they be. In other news, I just ordered a seal puller. Something I thought I had but didnt

I also had to buy one. I think the seals are like $8 a pc and im almost certain this is the park number. T3600705.

When I was doing it I was using the puller like a pry bar and using the real pointy end. I think next time I'll try to catch the lip and just pull on it rather than doing the action you would if you were pulling a nail with a claw hammer Like I was.

i have dent/seal pullers and what you can do is put washer with a nut on the end of it.
you insert the washer (a little smaller than the seal) so you are using about 30 percent pull on the seal and that usually saves the seal in case u can not buy one.
if there is a spring on the seal (and it comes off) then you can put it back on and put some light grease on the spring and it won't fly off when using a seal driver.

This is my deep needle bearing greasing tool. The manufacturer thinks it’s for steak marinade . Some dentist’s instruments found their good use too .

Never thought of those. I haven't even looked under the cover yet on the bike. @mo8414 do you think one of these on a grease gun would work? https://www.amazon.com/s?k=needle+b...f7b151&tag=googhydr-20&ref=pd_sl_1nice1n393_e

Talk about think out of the box! Brilliant idea! Do you need to warm up the grease first? I was thinking it might be a bit thick on a cold day?

Made a video on greasing the rear needle bearing. Been trying to get all the maintainance done before spring comes.

Most d/s bearings are packed to 50% of area capacity do to thermal expansion, any concern with the bearing being packed full? High speed needle bearing cages will come apart, i cant really tell how much grease is in there i was just curious if thermal expansion was taken into account.

No need to warm up, just push firmly. Ball bearing grease, Castrol Spheerol. The needle is thick.

They seem very thin to me. My needles are maybe 2mm or 1/10”

Its not really packed in, more just slathered all over it. Expansion shouldn't be an issue. Good point bringingnit up because the manual really doesn't tell you how much grease to use just to get in in the needle bearings.
