TABLE 1
When installing carbon graphite bushings, extreme care must
be taken to prevent breaking. Carbon graphite is a brittle
material and easily cracked. If cracked, the bushing will
quickly disintegrate. Using a lubricant and adding a chamfer
on the bushing and the mating part will help in installation.
The additional precautions listed below must be followed for
proper installation.
1. A press must be used for installation.
2. Be certain bushing is started straight.
3. Do not stop pressing operation until bushing is in proper
position. Starting and stopping will result in a cracked
bushing.
4. Check bushing for cracks after installation.

Carbon graphite bushings with extra interference fits are
frequently furnished for high temperature operation. These
bushings must be installed by a shrink fit.
1. Heat bracket for idler to 750ºF.
2. Install cool bushing with a press.
3. If facilities are not available to reach 750ºF. temperature,
it is possible to install with 450ºF. temperature; however
the lower the temperature the greater the possibility of
cracking the bushing.
4. Consult factory with specific questions on high
temperature applications.
