Does anyone have experience and / or advice on rebuilding outboard hubs? Is it possible to set bearing preload? Anything is greatly appreciated, thanks
I've just rebuilt the tatum rear hubs on my class 12 and they are way too tight. On the bench it takes one guy to hold the assembly and another person with a cheater bar to turn the hub. We used new timken bearings, races, seals. Swepco 101 grease, assembly tightened to 55ft/lb. They were not this tight before we tore them down.
Is there any way to set the bearing pre load? It seems to just be a set it and forget it type of assembly which seems ridiculous for something with tapered bearings. furthermore, all the bearing races required loctite or else they would spin. Is it possible that these hubs are just worn out of shape?
On another note, the car had broke an axle during its last race with the previous owner. Then broke another axle immediately after finishing the Baja 500 (my first race with this car). with all new axles and CV's going into V2R (my second race with the car) It incinerated a CV 350 mi's in. Luckily we replaced it on the course and were able to finish however post race teardown shows that all CV's have significant wear. Could all this be related to the hubs being too tight and causing excessive drive train fatigue or is this just coincidence???
All advice & knowledge is greatly appreciated as we plan to race the 1000 this year and
(obviously) would love to finish without dealing with driveline trouble
