Mike.
I've heard the same thing but I never had any issues...dgwilson said:I read with interest the comments on packing sealed bearings with grease.
As a maintenance electrician changing bearings on various sizes of motors. We found too much grease can be as harmful as not enough grease. The grease aids in smooth running and heat dissipation. Too much grease will cause overheating and seals to pop. The Grease then getting in all the wrong places. Granted these motors are 1450 rpm & over.
I always reckon a little is better than too much and if its not broken don't touch it. I think i greased my front hub once many years ago. Probably needs lookin at soon , but its still running smoothly.
Sparkplug,
Workshop manuals (Haynes and Clymer) give the following info which I hope is correct (as I have a MkIII the procedure is different). I'm sure if there is an easier way then somebody will say what it is? :
Wheel hub bearings
Unscrew lock ring (LEFT hand thread-either use Norton tool or make one).
Remove felt washer and spacer.
Replace the thick axle (spindle) washer and right hand side spacer onto the axle.
Insert the axle into the bearing on the left hand side of the hub.
Then by tapping on the end of the axle, drive the bearing into the hub as far as it will go the R/H bearing should start to move.
Remove the rear wheel axle and fit the front wheel axle threaded end first, in its place.
Keep the axle horizontal (if the wheel is vertical I suppose?) and tap the end until the R/H bearing and spacer are removed.
Insert rear axle with spacer into L/H bearing from the right hand side of the hub, then drive out the bearing.
Brake drum bearing
Remove drum from the brake assembly.
Remove spacer, washers and circlip from R/H side.
Screw the axle nut onto the short axle then drive out the bearing by tapping on the axle/nut.
Perhaps you should think about getting a manual if you do not have one?
Removing bearings - I'm stuck. I've read many threads on this including the advice below but I want to be sure before I take heat and a hammer to get the job done.
I don't see a a circlip. This is what I'm looking at. Is that a dished washer in this pict and if so, does that just pop out by prying? Circlip under that? mentioned below. 1974 850
Is this just a matter of heating and knocking them out.
