6.4.2 Tank Flange and Shaft Prepping
The tank flange comes from the factory with the shaft bearing, grease, shaft seal
and scraper installed at the factory. All tank flanges are serialized and pressure
tested. Great care must be taken not to damage the shaft seals and the flange
gasket surface during the installation.
Calculate the necessary length of the main shaft from the length of the retraction
tank and cut off the extra length if necessary. If you have to cut the shaft, refer to the
shaft drawing located in Part 8 for the proper cutting procedure. If you do not follow
the proper procedure, you will damage the shaft seals and shaft scraper when you
pass the shaft through the main shaft bearing assembly.
See Part 8
“Attachments and Drawings”
for the tank flange and shaft cutting
detailed specification.
