4-6 BLADE SPINDLE SERVICE
If shaft bearings or other parts require replacement, it is recommended that a Locke Turf dealer or other quali-
fied person service the blade spindle. If blade spindles must be disassembled, a special wrench kit must be
used to prevent damage to the assembly. This Wrench Kit (Part Number 50026073), including a sheave
wrench, carrier wrench and complete instructions, is available form Locke Turf. (Figure 4-6) Refer to “Blade
Spindle Service” at the rear of this manual.
