GENERAL IMPORTANT NOTES
Worn parts should be replaced as required.
Synthetic rubber "0" ring seals may be pried out of their
grooves in the rear journal and the rear plug and replaced.
Replacement of the Front Bushing, in housing, involves
pushing the old bushing inward from the front end of the
body and forcing a new bushing into place from the inside
of the body.
The rear bushing may be pushed out of the rear journal in
either direction, preferably rearward. To replace, observe
that longitudinal pin is in place, align the groove in the
bushing with the pin and press into place from the rear until
the front of bushing and front face of the journal is flush.
Great Care should be taken to avoid damage or distortion to
the 3/8" diameter scavenger tube, force-fitted into the end
of rotor. This tube must run concentric with the rotor, other-
wise leaks may develop.
The motor should be run a short time at low speed, after assem-
bly, without any scavenging flow to fully seat the sealing sur-
faces. Do not run at free (no load) speeds over extended per-
iods. Be sure to introduce lubricating oil into the operating
air line whenever the TP-302 is in operation.
Keep the oil-impregnated front bushing and thrust ball bearing
supplied with oil by filling the reservoir through the oil hole
in the nose of the body. Remove Set Screw, key 3.
