Bush extraction tool, to pull out bushes pressed tightly into drillings in an IC motor block, has a clamp to grip the bush to be pulled out within a support tube on the surface around the drilling

摘要

The tool (80) to extract a cylindrical tube (81) from a drilling, e.g. a bush fitted tightly into a drilling in the block of an internal combustion motor, has a clamp (1) which is inserted into the bush to be extracted and clamped against it. The clamp is within a support tube (65), placed over the top of the bush against the surface around the bush drilling. A pull system (58,69,70) is fixed axially to draw the bush into the support tube. The surfaces of the clamping segments (15,16) are hardened.
