By-Pass Filter
A by-pass filter is often used in conjunction with a full-
flow filter, never use a by-pass filter instead of a full-flow
filter.
DISASSEMBLY

Remove clamping ring capscrew and lift off cover.
2.
Unscrew upper support element hold-down assembly
and lift out hold-down assembly and element.

1.
Inspect hold-down assembly spring/seal, drain plug,
connections and filter cover "0" ring.
Replace if
damaged.
2.
Clean orifice in tee-handle or orifice hole in standpipe;
these are very important and control amount of flow
through the by-pass filter.

Install new element.
2.
Replace upper support element hold-down assembly
in filter and tighten down to stop.

Mountings (Fig.
7-3) Vertical Mounting
Vertical or up-right filters can be mounted with up to 45
deg.
inclination.
The inlet should be positioned at the
highest location to minimize drain back of oil when
engine is shut-down.
None of the vertical mounted filters
contain anti-drain back valves on either the inlet or outlet.
Horizontal Mounting
Horizontal mounted filters can also be mounted up-right
when it is desirable to have both inlet and outlet hose
attached to bottom end of filter.

Flow Characteristics And Specifications
With a 180 deg.
F [82 deg.
C] oil temperature and with
engine at high idle, oil flow through the by-pass filter
should be a minimum of 1-1/2 to 3 gal.
[5.7 to 11.4 lit]
per minute maximum (total flow through both filters) to
insure maximum filtration and maintain adequate oil
pressures.
