After the replacement (spare) belts have been installed onto
the clutch and lower pulley, it will be necessary to install
a new set of spare drive belts onto the spare belt holder.
Perform the procedure shown below to install new drive
belts back onto the spare belt holder:
1. If necessary, place the trowel on suitable supports
(jack-stands) and observe all safety precautions.
2. Starting at the left-side gearbox, use a 1/4" allen
wrench and remove the 3 bolts and lock washers that
secure the CV-joint (Figure 24) to the left-side gearbox.
Retain mounting hardware for later use.
