INSTALLATION OF BUSHINGS
When installing carbon graphite and silicon carbide bushings,
extreme care must be taken to prevent breaking. Carbon
graphite and silicon carbide are brittle materials 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. Note:
Bushings cannot be replaced in Acetal or PEEK idlers.

2. For standard end clearance, back off the thrust bearing
assembly the required length measured on the outside
diameter of the bearing housing. See Table 3.
3. Tighten the two setscrews in the outboard face of the
bearing housing with equal force against the bracket. Your
pump is now set with standard end clearances and locked.
NOTE: Be sure the shaft can rotate freely. If not, back off
additional length on outside diameter and check again.
Best practice is to verify pump end clearance with a
feeler gauge or a dial indicator.
4. Operating the pump at higher temperatures or viscosities
may require additional end clearance. Contact your
local Viking representative for specific clearance
recommendations. The additional length on the outside
diameter of the bearing housing for an extra 0.001” of
end clearance is shown in Table 3.
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.
5. Silicon carbide bushings require a shrink fit. Heat the
770 stainless idler to 450°F (232°C) before installing a
cool silicon carbide bushing.
