8. Make sure that wave washer (item 4) is pressed into
reel drive shaft bore of transmission cover.
9. Note transmission belt routing for assembly pur-
poses (Fig. 35).
10.Remove transmission belt from drive and idler pul-
leys in transmission.
11. Check condition of all pulleys and idler components.
12.Clean inside of transmission before reinstalling new
belt.
Drive Belt Installation (Fig. 34)
IMPORTANT: During assembly, make sure that
transmission cover is installed with fasteners prop-
erly torqued before applying tension to transmis-
sion belt.
1. Install new transmission belt onto pulleys in trans-
mission. Make sure that belt is correctly routed around
drive and idler pulleys (Fig. 35).
2. Make sure that wave washer (item 4) is pressed into
bearing bores of transmission cover. Also, make sure
that two (2) dowel pins are pressed into bores in the
transmission housing.
3. Position new gasket to transmission assembly. Align
gasket to two (2) dowel pins in transmission housing.
4. Install transmission cover. If necessary, use a rubber
mallet at dowel locations (Fig. 36) to seat cover to trans-
mission.
5. Install seven (7) washer head screws to secure cov-
er to transmission. Tighten screws as follows:
A. First, using an alternating crossing pattern,
torque all screws from 15 to 40 in−lb (1.7 to 4.5
N−m).
B. Again using an alternating crossing pattern,
torque all screws from 85 to 95 in−lb (9.6 to 10.7
N−m).
6. Apply tension to transmission belt by rotating the en-
gage/disengage shaft counter−clockwise (see Trans-
mission Belt Tensioner in the General Information
section of this chapter).
7. Install key (item 6) to transmission shaft. Apply anti-
seize lubricant to top of key.
8. Slide coupler (item 11) onto transmission shaft until
it is flush with the end of the shaft. Secure coupler with
two (2) set screws (item 12). Torque set screws from 60
to 65 in−lb (6.8 to 7.3 N−m).
9. Secure coupler guard (item 10) to transmission.
10.Slide telescoping coupler onto transmission shaft so
that drive shaft wire engages hex shaft on transmission.
Make sure that telescoping coupler is properly attached
to cutting unit hex shaft.
11. Install engine to machine (see Engine Installation in
the Service and Repairs section of Chapter 3 − Engine).
