PUMP SERVICING
NOTE:
Air motor is lubricated with a life tested
synthetic grease (Balcrank
®
P/N 826733) at
the factory. This grease coats all parts and
repels air line moisture to inhibit corrosion. It
is imperative that any grease removed during
routine maintenance be replaced. Contact your
local Balcrank
®
Distributor, using the above part
number, for replacement grease.
NOTE:
The following steps and item numbers
pertain to the stub pumps. Except for a few fluid
section components (pump tube, pump rod, fluid
piston, etc.), stub and drum pumps are alike.
When repairing a drum pump, pay close attention
to different parts that may carry the same item
number as their stub counterparts, such as the
pump tube (35).
Repair Kits:
There are three kits available to
repair the stub and drum “Bobcat 130” pumps:
* 827711 (air piston parts for all pumps)
** 828069 (fluid seals for carbon steel pumps)
*** 828070 (fluid seals for stainless steel
pumps).
