(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
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
cooling fi ns up. Attach ground lead to outer screw
and washer, then tighten mounting screws to torque
specifi cation. Connect plug to rectifi er-regulator.
