Continuing on with the babbitting (whitemetalling) job.
The whitemetalling turned out really good, I didn't face much off the bronze flange, just took off the high spots, the few marks there won't cause any problems.
Both mains sitting on crank, arhh I'm slowly getting there.
I cut the groove in with a tungsten carbide ball end cutter in a hand held die grinder.
This is out of sequence. I made this measuring stick to measure the parrallism of the compressor crankcase before machining the main bearings.
Close up of one end of the measuring stick.
I adjusted the measuring anvil on one place of the crankcase face then checked the at different places around the face.
Cutting gaskets,they are 0.25mm (.010 inch) thick.
Crank assembled in crankcase and checking the end float. I found there was too much, so I set the main housings back up in the lathe and machined the necessary amount off each cast iron flange so I ended up with about 0.16mm (about .006 inch). The crank turns really nicely with no tight spots.
This should be a new window, minimise or close it to return to Home Page or press
