and supplied by OEM, refer to your equipment
manual for reassembly detail.
NOTE: Earlier engines were built with spring clamps
securing oil cooler hoses. New spring clamps
are recommended any time disassembly is
performed, or if clamps have been loosened
(expanded) several times.
Newer engines are built with Oetiker clamps
securing oil cooler hoses. Refer to position of
each Oetiker clamp as noted in disassembly,
before installing and crimping.
1. Connect hoses between oil fi lter adapter and oil
cooler. Secure with new clamps. When Oetiker
clamps are used, only use an Oetiker clamp pliers to
crimp them.
2. Align oil cooler with bosses in backing shroud
assembly. Secure with screws and washers but do
not tighten at this time.
Install Ground Lead and Rectifi er-Regulator
Connector (Standard Ignition)
1. Attach ground lead to outer rectifi er-regulator
mounting screw and washer, then torque mounting
screw to 2.5 N·m (22 in. lb.).
2. Install wiring harness clamp mounting bracket with
harness ground lead to inboard #1 side cylinder
boss.
3. Install rectifi er-regulator connector.
