HYDROSTATIC REMOVAL & RE-INSTALLATION
14. If the bevel gear on the end of out-
put shaft is going to be removed, note
the number of shims between the gear
and hydro-the same number must be
re-installed during assembly.
HYDROSTATIC REPAIR
If the hydrostatic transmission is in
need of repair, refer to the Eaton
Service and Repair Manual. This
manual is available from the Bolens
factory.
INSTALLATION
(Fig 3-4)
1. Clean the mounting surface (on the
hydro and transaxle) of all oil, grease
and dirt before re-installing the hydro.
Run a thin bead of silicon rubber
around the mounting surfaces and
around bolt holes (not In the bolt holes).
Secure with the four (4) capscrews and
lockwashers removed earlier (C, Fig.3-
4). Coat mounting .screws with loctite
242 (or equivalent) and torque them to
24 ft.-lbs. (32.5 N-m) when fastening.
2. Check for pinion to bevel gear
backlash using a dial indicator to check
the end play of the brake shaft (Z, Fig
3-4), backlash at this point should be
.015" to .020" (this will give the proper
backlash between the bevel and pinion
gears. If end play is not within these
tolerances it will be necessary to
remove the transmission from the
differential, remove the pinion gear (Y)
from the transmission, and reshim. If
the end play is less than .015" you will
need to add shims. If il is more than
.020", you will need to remove shims.
Coat bolt with Locktite 242 (or
equivalent) and re-install gear washer
and bolt and torque to 24ft-lbs. Re-
assemble and check for end-play.
Reinstall suction line on BOTTOM of
hydro and rear axle.
3. Re-install return line between filter,
base and side hydro.
4. Re-install pressure line to TOP of
hydro.
5. Re-install control shaft. Torque
locknut to 75 in-lbs.
6. Install drive shaft on input shaft.
(Apply anti-seize to shaft). Tighten both
set-screws.
7. Install fuel tank (on 2-speed
Models, route shift shaft through left
hand tank support). Secure tank with
hardware removed earlier (Fig. 3-3).
8. Route fuel line and sending unit
wires under fuel tank and install. Tie-
strap wires and fuel line as needed.
9. Install range light panel and tighten
hardware (Install new tie straps to
secure wiring harness away from
rotating parts).

10. Install fender. Route seat switch

11. Hook up seat switch wires. Install
seat.
