Installation Instructions
This kit is for engines with an existing spin--on bypass filtration system.
1. Identify the existing engine bypass filter location. Verify that it is the BYPASS filter location and NOT
the normal full--flow filter location.
2. Remove the existing bypass filter and thoroughly clean the filter location and the engine’s threaded spud.
3. Remove the canister from the LFS 802--S filter head by turning the head in a counter--clockwise rotation
(use a strap wrench if necessary). Also remove the filter element from the head by turning the element
in a counter--clockwise rotation.
4. Lubricate the three O--rings (see photos below) on the LFS 802--S head with oil. Apply Loctite 277 on
the engine spud and the LFS 802--S female mounting threads and spin the head onto the engine. Use
a 1 1/8” socket wrench to securely fasten the head to the engine. Tighten until the head stops rotating.
5. Apply Loctite 277 to the two 3/8”--16 set--screws and thread them into the bottom
of the LFS 802--S filter head until contact is made with the engine.
Tighten
set--screws evenly.
After initial contact turn each set--screw approximately 1/8 to
1/4 turn with a 3/16” Allen wrench to allow the cupped point to securely engage the
engine.
NOTE -- It is possible that both set--screws will not engage the engine at the same
time. This may be because one of them it is located within the oil entrance port.
In this case, continue to thread the loose set--screw until it does engage the engine.
