8. Remove fasteners that secure transaxle to frame:
A. Cap screw (item 17) and pyramidal washer (item
19).
B. Four (4) cap screws (item 5) and pyramidal wash-
ers (item 4).
C. Four (4) cap screws (item 30), lock washers (item
8) and nuts (item 31). NOTE: One of these cap
screws is used to secure belt guide (Fig. 8).
9. Carefully lower transaxle and remove from machine.
10.If necessary, brake disc (item 29) can be removed
from transaxle brake shaft by loosening two (2) set
screws (item 27) and sliding disc from shaft. Locate and
retrieve woodruff key (item 16).
11. If needed, remove pulley from transaxle input shaft:
A. Remove three (3) cap screws (item 15) and lock
washers (item 14) that secure taper lock bushing to
pulley.
IMPORTANT: When removing taper lock bushing,
tighten cap screws progressively and evenly. Ex-
cessive or unequal pressure on the screws can
break the taper lock bushing flange.
B. Insert cap screws into threaded removal holes of
the bushing. Tighten screws progressively and even-
ly until the pulley is loose on the bushing.
C. Remove pulley and bushing from transaxle shaft.
D. Locate and retrieve woodruff key (item 16) that lo-
cates bushing on transaxle shaft.
Installation (Fig. 7)
1. If brake disc was removed:
A. Position woodruff key in transaxle brake shaft slot
and slide brake disc (hub first) onto shaft so disc hub
is .060” (1.5 mm) from transaxle housing.
B. Apply Loctite #242 (or equivalent) to threads of
two (2) sets screws (item 27). Secure brake disc on
shaft with set screws.
2. If pulley was removed from transaxle input shaft:
A. Make sure that tapered surfaces of pulley and ta-
per lock bushing are thoroughly clean (no oil, grease,
dirt, rust, etc.).
B. Place woodruff key (item 16) in input shaft slot.
Slide pulley (item 13) and then taper lock bushing
(item 12) onto transaxle shaft making sure that ta-
pered surfaces of pulley and bushing align.
C. Align threaded holes of pulley with non–threaded
holes of bushing. Loosely install three (3) cap screws
with lock washers into pulley threads.
IMPORTANT: When tightening cap screws, tighten
in three equal steps and in a circular pattern to pre-
vent bushing flange damage.
D. Align the outside of bushing with the inside of the
groove on the input shaft (approx 1/8” from end of
shaft). Tighten three (3) cap screws to a torque from
90 to 120 in–lb (10.2 to 13.6 N–m) in three equal
steps and in a circular pattern to secure pulley and
taper lock bushing.
3. If sprocket (item 11) was removed from transaxle
shaft, apply antiseize lubricant to transaxle shaft before
installing sprocket. Also, apply Loctite #242 (or equiva-
lent) to set screws (item 6) before installation.
4. Position transaxle to the frame. Attach transaxle to
the frame with fasteners removed during disassembly:
A. Four (4) cap screws (item 30), lock washers (item
8) and nuts (item 31). NOTE: Leave front cap screw
on input shaft side of transaxle loose until belt guide
is installed (Fig. 8).
B. Four (4) cap screws (item 5) and pyramidal wash-
ers (item 4).
C. Cap screw (item 17) and pyramidal washer (item
19).
5. Install knob to shift lever.
6. Install drive belt to transaxle and engine pulleys (see
Traction Drive Belt Installation in this section).
7. Install brake caliper to machine (see Brake Caliper
Installation in Service and Repairs section of Chapter 6
– Chassis).
8. Install drive chain to both transaxle sprockets (see
Drive Chain Assembly in this section).
9. Check and adjust transaxle oil level (see Operator’s
Manual).
