I am installing clean rotors and new bearings/seals in my '67. The rotors had a lot of grease packed in the bore between the inner and outer bearings. Is this correct? Should I do this with the new rotor or is packing the bearings and a dab behind sufficient? I think the shop manual shows that the space between the bearings packed with grease up to and behind the bearing races. What do you guys do? Yes, high temp grease for disc brakes...
I just put a small amount in the space between the bearings. Don't know if it really does anything other than makes me feel happy. Like above, filling it is just a waste and more cleaning when repacking bearings.
A golf ball blob in there and call it good. Once it heats up a time or two it will soften up and distribute evenly throughout.
To me, I'd rather have too much than not enough. Grease is cheap comparatively.... Also, as far as bearings, a loose bearing will go all day, a bearing that's too tight will faill pretty quickly
Red-n-Tacky type grease will "pull" new grease in by the nature of its "stringy" behavior. So, it may be beneficial for some "extra" grease to be available. (Used it on fighter aircraft wheel bearings in the USAF.) Packing the cavity will not hurt. So, even of that extra grease never sees the business end of the race/bearing, it poses no issues. I pack mine, use the Red-N-Tacky, and have never had any negative issues in almost 50 years.
Try Klubber grease and read technical stuff on this page drpperformance.net they might know a thing or two about bearings. Peace, Kacper.
Hmm, i am relatively poor but if i have to put something in my stomach or in my car be it the best i can get. I prefer trouble free using than going to doctors. Sometimes it can be overkill and overthinking , but if You have to make it like 3 times in next 10 years, than i don't see how buying good grease in small package could be so much $$. Here in Poland i got 100ml of klubber for 20$, should be ok for 2-3 changes maybe more. but believe me, wheels are turning like there is no tomorrow. Happy New Year to All Peace, Kacper.
I was taught to fill the hub and the space between the inner bearing and seal. The reasoning is that as the wheel and bearing spins, it tends to sling the grease out of the bearing. If the hub is full of grease, it has no place to go, thus staying in the bearing.
The only time I’d pack the hub with grease was on boat trailers along with the “Bearing Buddy” The purpose of that was the Bearing Buddy kept slight positive pressure inside the hub to prevent water from seeping in when the warm hubs go into cool/cold water.
