REASSEMBLY OF PUMP DRIVE
For reassembly, use the reverse procedure of 1 through 8.
NOTE: Plastic cord used for gasket material under pump adaptor plates and input housing is not reusable. Replace
with new material when reassembling. See Figure 3 for installation of cord gasket. Place bolts should not be
reused. Clean the old Locktite out of the bolt hole threads. Install new place bolts with Locktite 262, on the
engine adaptor and pump pad. Place bolts are used in pump drive pad, torque studs to 150 ft. lbs..
Do not attempt to reuse this gasket. For assembly use new
gasket material.
On flywheel housings involving more than 4 bolt holes, be
sure cord gasket lap joint falls behind one hole location which
will be used for a bolt or stud fastener. Do not lap ends
behind an unused bolt hole.
Remove protective paper strip from cord and with adhesive
side next to metal, install around pilot. Cross ends, as shown,
behind bolt hole and let ends extend beyond flange. Use
caution in assembly to case, to prevent gasket dislocation.
REPLACEMENT OF OIL SEAL
Install oil seal from engine side of engine adaptor. The rubber lip of the oil seal must point toward the inside of pump
drive gear box.
NOTE: Drive in direction of arrow.
Drive Plate Models:
When installing drive plate on flywheel, be sure the long end of the drive plate hub is toward the engine. The hub
should slide into the pilot bearing bore of the flywheel to ensure proper alignment of the drive hub and drive shaft.
NOTE: Arrow indicates engine side.
