ABSTRACT:
A tool for lifting the fork rod of a diesel engine for ready replacement of a fork blade. The lifting tool includes a base having an upper arcuate edge for engagement with a maintenance manhole of the diesel engine. A fulcrum plate projects from the base and has a bore formed therethrough. A two-shafted lifting arm has a complementary bore for pivotal movement with respect to the base by insertion of a fulcrum shaft through the aligned bores. A handle is insertable into one of the shafts, and a fork into the other. The fork includes a fork head having a pair of spaced apart tongs including means for engagement with the fork rod. By depressing the handle, the fork arm may be pivoted into a raised position, thus lifting the fork rod when it is engaged with the tongs. Means are also provided for fixing the fork head into the raised position.
