Inspect PTO Clutching Belt
Tension
Service Interval: After the first 2 hours
Check every 2 hours
for the first 8 hours of
operation.
Every 40 hours thereafter.
1. Stop engine and wait for all moving parts to stop.
2. Engage PTO lever.
3. Look through the round hole in the left rear
corner of the engine deck to inspect blade
clutching belt tension. Bolt on blade engagement
linkage bellcrank and indicator arm should align
within 1/16 inch (1.6 mm) (see Figure 15). Refer
to PTO Engagement Linkage for adjustment.

Thread Locking Adhesives

Thread locking adhesives such as "Loctite 242"
or "Fel-Pro, Pro-Lock Nut Type" are used on the
following fasteners:
• Pump sheave setscrews.
• Square head setscrews on hydro pump control
arms.
• OPC lever setscrews.
• Lower sheave retaining bolt on clutch arm.
• Shoulder bolts in ends of speed control crank.
3. Align bolt to indicator
within 1/16 inch (1.6
mm)
4. Turnbuckle
• Sheave retaining bolt in end of engine crankshaft.
• Fuel tank bulkhead fitting threads
Adhesives such as "Loctite RC/609 or RC/680" or
"Fel-Pro Pro-Lock Retaining I or Retaining II" are
used on the following:
• OPC lever hubs and cross-shaft.
Note: Care must be used not to bond the
bearing, next to each OPC hub, to the cross-shaft
which could cause binding of the OPC levers and
erratic operation.
• Fuel tank studs, where studs are inserted into tank.
Mobil HTS Grease (Or
Food-Grade Anti-seize)
Mobil HTS grease (or food-grade anti-seize) is used
in the following locations:
• Between the cutter housing spindle and bearings.
• Between the cutter housing spindle and sheave.
• Under top cutter housing bearing guard.

Copper-Based Anti-seize

Copper-based anti-seize is used in the following
locations:
• On threads of Blade Bolts. See Check Mower
Blades section.
• Between engine crankshaft and pump and blade
drive sheaves.
• On clutch arm assembly between bearings and
shaft and between lower sheave and shaft.
• Between pump shafts and sheaves.

Dielectric Grease

Dielectric grease is used on all blade type electrical
connections to prevent corrosion and loss of contact.
Dielectric grease should not be applied to sealed
connectors.
