Re: 85 Force Bearings
Since with the exception of the top ball bearing, all other crank bearings are roller that ride on either the crankpin or crank journal as the inner race, if the bearings are spalled or destroyed, the crank will usually be also. Using a crank that is even slightly spalled will result in short service life and another rebuild. So: Check the crank carefully.
The big end and the small end of the rod is also a bearing surface and again, if damaged at either end, the rod must be replaced. If the small end is damaged carefully check the wrist pin. Wrist pins must be pressed out using at least a 4 ton press. There is a special tool to remove and re-install wrist pins. It must be used to prevent damaging the needle bearings and wrist pin keepers in the small end.
The top ball bearing is a standard part that can be purchased at the local auto store or a bearing supply store. It was used in the rear end of some rear wheel drive Fords.
To replace it you need a heavy duty bearing puller ( the kind that is two halves that clamp together under the bearing) and a 10 to press.
To install the new bearing, simply heat it on a 100 watt light bulb for about 10 minutes. Using a glove, quickly slide it down over the crank and seat it.
