1. Scrape all debris from the gasket mating surfaces
on the front cover (12) and the pump housing
(1), then clean with acetone or brake cleaner to
remove any residue. This is critical to ensure a
leak-free assembly.
NOTE:NOTE:
NOTE:
The pump housing and front cover must
be free of dirt, debris and residue to ensure a
leak-free seal.
2. Place a bead of compatible sealant on the gasket
surface of the front cover (12), to hold the gasket
in place during assembly.
NOTE:NOTE:
NOTE:
The hole pattern of the front cover (12),
gasket (11), and housing are asymmetric. This
ensures that the gasket and cover go on in only
one direction.
3. Line up the holes in the gasket (11) with the holes
in the cover (12) before placing the gasket on the
sealant bead. Place the gasket on the cover.
4. Line up the front cover and gasket with the pump
housing (1) by placing a socket head cap screw
(14) and washer (13) in the top hole and screwing
it into the pump housing (1).
5. Install the remaining front cover screws (14) and
washers (13). Torque the screws oppositely to
25 in-lb (2.8 N•m).
NOTE:NOTE:
NOTE:
Do not over-tighten the front cover
screws. This will cause the gasket to deform and
the pump to leak.

Overlling the pump
housing with hose lube will increase pressure
in the pump housing, causing hose lube to leak
from the cover or the clamp area. Pre-measuring
the correct amount will help prevent overlling.

3. Wrap the vent plug (15) threads with PTFE tape
and screw it into the vent port carefully.
NOTE:NOTE:
NOTE:
Higher operating speeds provide more
vigorous lubrication, which may cause splashing of
oil. When operating at a speed of 85 RPM or greater,
reduce the amount of hose lube as shown in the
table below.
