Repairing a manual gearbox is a difficult task for a novice auto mechanic. In addition to having to remove and install a large number of small parts, you will need to accurately measure and, if necessary, adjust numerous gaps by selecting gaskets. Therefore, it is recommended to entrust the bulkhead of the gearbox to a specialist or purchase an already restored unit.
However, a motorist with some experience, if he has the tools, may well sort out the manual transmission on his own. Work carefully and methodically so as not to miss anything.
The tools needed for the overhaul are pliers to remove the inner and outer circlips, bearing pullers, a slip hammer set of punches, a micrometer, and possibly a hydraulic press. In addition, you will need a large, sturdy workbench and a vise.
During manual transmission disassembly, carefully record how each of the components is located to facilitate subsequent installation.
Before disassembling the transmission, try to find out which of its components is malfunctioning.
