properly seated.
2. Install larger spring into fi lter housing.
3. Insert oil fi lter cup, aligning cutout with
corresponding section in housing.
4. Install nipple in housing and tighten to torque
specifi cation.
Installation
1. Make sure all sealing surfaces are clean and all
three dowel pins are in position. Install or check new
O-rings are around all three oil fi lter adapter dowel
pins.
2. Install oil fi lter housing assembly to adapter and
secure with M8 hex head screw. Make sure housing
is fl at on crankcase and all O-rings remain in
position. Tighten screw to torque specifi cation.
3. Oil fi lter may be installed now or upon completion of
engine assembly.
Install Backing Shroud Assembly
NOTE: New hose clamps are recommended for
reassembly, or if clamps have been loosened
(expanded) several times to avoid leakage.
1. To aid assembly, install lower oil cooler hose onto oil
fi lter housing prior to installing backing shroud
assembly, and secure with a clamp.
2. Install backing shroud assembly and secure to
crankcase with four M6 screws. Tighten screws to
torque specifi cation.
Install Stator, Wiring Harness, and Rectifi er-
Regulator
1. Apply pipe sealant with Tefl on
®
(Loctite
®
PST
®
592™
Thread Sealant or equivalent) to stator mounting
holes.
2. Position stator, aligning mounting holes so leads are
at bottom and toward rectifi er-regulator mount on
No. 1 side.
3. Install and tighten hex fl ange screws to torque
specifi cation.
4. Route stator wires under two molded clips in backing
shroud assembly.
5. Check terminal on end of B+ charging lead to be
sure locking tang is angled upward. Insert terminal
into center location of connector until it locks into
place.
6. Install wiring harness under molded clips in backing
shroud assembly.
7. Position rectifi er-regulator onto mounting posts with
