8. Replacing the Timing Belts

Part 2: Maintenance

164

Installation : U2 Belt

(1) Pass a new U2 belt and the Z belt through the shaft from above, and lift the spline plate

to make those belts through.

(2) Place the Joint #3 motor unit in the arm. The motor cables should be facing Joint #2.

(3) Fit the new U2 belt around the U3 and the small U2 pulleys. And, fit the Z belt

around the Z2 and the Z1 pulleys. Ensure that the gear grooves of the belts and
pulleys engage properly.

(4) Secure the spline plate with three bolts (M4

10).

(5) Position the Joint #3 motor plate, Joint #4 countershaft unit and Joint #4 motor plate

on the arm. Be careful not to slip the belts from the pulleys while maintaining proper
interval between the units. Secure them lossely for the time being using the following
bolts: 4-M4
