Hey all,
I have recently gotten into the wheel hubs and dared to look at what I have been driving on.
Before I got started I ordered Bearing Seals for two Tigers and a set of wheel bearings for one car. My thought was to do Black Tiger and if I needed the Wheel Bearings? I would use them. As it turned out the bearings were fine in Black so I cleaned up and packed the old bearings with Redline syn grease and it is back on the road. I remembered/realized while doing that first job that I was not prepared for changing out the bearings because the inner races need to be knocked out. New inner races are "pressed" in and I could not do that.
Fortunately we have friends that can and will help. Darrell has done this before and had a hydraulic press. When I tore down TigerBlue it was clear that I would be installing the new bearings. The inner race outboard on the left side had chatter marks. On the right moisture inside the hub had produced a few rust flakes and etched a signature on the little outboard roller bearing. Photos below document the pressing part of the work.
D. used an aluminium drift punch to pound out the old races. There are notches cast in the hub to allow you to beat out the old race. A soft metal punch is prefered to avoid damage to the machined surfaces in the hub. Both of my hubs had dremal tool marks. Evidence that the bearing races had been whacked with a steel tool and then ground back (high points) with a rotary tool.
The "press" powered the new pieces in. D. had a variety of sizes of the things he stacked to drive the bearing races in. Note that when the hub was "studs down" he used spacers to make the studs stand off the fixed surface so that we did not move the studs which are also pressed in.
Later that weekend I put Blue back together with hand packed new bearings.
