Hi, It's Dan. thanks for the request. Are you referring to the wear ring that is installed on the crankshaft? could you get me the complete model and serial number of the engine and could you tell me some more details on the procedure and tooling used to install the seal? there is a front and rear main seal installation tool. Let me know
Thanks for the update. Maxxforce 9, 10, 11?
If the crankshaft seems to have too much radial or end play it will be a good idea to get a dial indicator on it and see if possibly it is bent, worn out of spec journals or bearings and thrust washers ( Remove pan/visual inspection). If the crank runout does not reveal a bent crank it may be possible a bearing roll in will cure your problem if the bearings are excessively worn on inspection. If they are OK then inspect the crank for imperfections that would interfere with the wear ring sealing on the shaft properly. I use a thin coating of green loctite/ bearing mount for the wear ring.
Hi, Did you get this resolved?
