Crankcase Repair

This highly specialized work is priced strictly on time @ $65.00/hour and material. I will attempt to give an estimate, however, this work can be extensive and involved and you will be charged for actual time spent on the repair. You can save a money by disassembling the cases and ensuring they are generally clean and drained. Most of the damage I see is to the bottom and rear right side case. Usually a gear breaks and the broken parts get jammed up against the case, the case will fail. Do yourself a favor, at first signs of hard shifting and missed shifts, investigate and repair the problem before you have to deal with the situations in the pictures below. Each weld repair is custom designed to address your particular damage in the best possible manner. The early cases are very thin in the countershaft boss area, very often the best option is to plug the speedo drive and weld reinforcement around the boss.

When doing large weld repairs the cases are bolted together and heated in an oven to preserve alignment and prevent warping. After welding they are reheated and cooled slowly to relieve stresses.
I also weld inside the case to ensure the deepest possible penetration, greatest strength and best leak prevention. Additionally, a deep "V" is ground into all cracks before welding to achieve deep penetration.
