connecting rod small end bush extractor and inserter.
this tool will fit ANY engine
this is a very delicate job, as the bushes are sold slightly undersize, and need to be reamed out to fit the piston pin perfectly.
You must be highly skilled to ream the bush to the correct size. You can use a standard 20mm reamer or an expanding one or a 20mm end mill. This will get you to almost the correct size which is 20.002mm. It is a split bush made of steel and bronze? I think, 22mm outside and 19.95mm inside. the piston pin is 20.00mm diameter. You have to ream out 0.052mm, approx 0.0025 thousands of an inch [2.5 thou]
