11 I Checking the compressor parts
Checking compressor parts for damages and wear
Before re-using removed compressor parts we recommend that they be checked for usability.
The wear limits listed below should be taken into consideration:
1 Piston - cylindre bore
2 Connecting rod - piston pin 0.03 mm
3 Crankshaft - connecting rod 0.08 mm
Other components have to be examined according to the following criteria:
Cylinder liners
The cylinder liners should not have any visible damages in the piston movement area.
If there is fluting, the casing should be replaced.
Crankshaft
The bearing surfaces should not have any damages. The oil channels should be clean so that an
unhindered oil flow is ensured.
CAUTION Remaining oil can cause eye injury!
When compressed air is used, remaining oil can splash out of the oil channels.
Wear protective googles.
Clean the oil channels with compressed
air and check for passage
