FRONT CLUTCH

Disassembly

Remove retainer plate snap ring. Remove retainer plate, drive and driven plates and dished plate. See

Fig. 15

. Note position of dished plate

for reassembly. Using appropriate compressor, compress return springs to remove spring retainer snap ring. Remove spring compressor.
Remove spring retainer and return springs. Apply air pressure to front clutch oil passage and remove front clutch piston.

Inspection

Inspect all parts for wear or damage and replace as needed. Return springs must have free length of .992-1.071" (25.20-27.20 mm). If free
length is not within specification, replace spring(s). Check inside diameter of clutch drum bushing. If diameter exceeds 1.735" (44.08 mm),
replace bushing.

Reassembly

1. Reverse disassembly procedure to reassemble. Install new seal rings on piston and install piston by applying even pressure on perimeter

while rotating piston. Install front clutch return springs and retainer. Compress spring retainer. Install snap ring.

2. Install dished plate. See

Fig. 15

. Install drive and driven clutch plates, retaining ring and snap ring. Using feeler gauge, measure

between snap ring and retaining plate. Clearance should be .063-.071" (1.60-1.80 mm). If clearance is not correct, select correct
thickness retaining plate. Retaining plates are available in thicknesses of .205" (5.20 mm) to .244" (6.20 mm) in .20 mm increments.

3. Place front clutch assembly over oil pump and apply air pressure (57 psi maximum) to front clutch oil passage in oil pump to check for

proper front clutch operation. See

Fig. 16

.

GOVERNOR ASSEMBLY

Disassembly & Reassembly

Secure governor assembly in vise. Using hammer and pin punch, drive out governor shaft gear spring pin. Remove gear. Remove sleeve from
shaft. Remove oil screen clamp and screen. See

Fig. 17

. Clean all parts as needed. Lubricate parts with ATF. To assemble, reverse

disassembly procedure. Replace spring pin.

IDLER GEAR ASSEMBLY

Disassembly & Inspection

Attach Idler Shaft Holder (J-35286) or hex wrench to idler shaft and support assembly in vise. Remove lock nut. See

Fig. 18

. Remove

bearing, spacer, idler gear, adjustment shim(s) and remaining bearing. Press bearing outer races from idler gear. Check all gear teeth for wear or
damage and bearings for breakage or unusual wear.

Reassembly

1. Place idler shaft holder or hex wrench in vise and place idler shaft on wrench. Install outer races in idler gear. Place bearing, idler gear,

adjustment shim, spacers, bearing and nut on idler shaft and tighten nut to 94-130 ft. lbs. (127-176 N.m).

2. Measure bearing preload. Mount idler gear in vise. Using INCH lb. torque wrench, measure idler gear shaft turning torque. Turning

torque should be .26-8.0 INCH lbs. (.03-.90 N.m). If preload is not within specification, change selective shims. Selective size shims are
available from .004" (.10 mm) to .008" (.20 mm) in .04 mm increments. One .020" (.50 mm) shim is available. DO NOT use more than
7 shims. Once correct preload is obtained, retighten idler gear locknut to 94-130 ft. lbs. (128-177 N.m)

LOW-REVERSE BRAKE

Inspection

Check all components for signs of damage or excessive wear. Check free length of return springs. See

LOW-REVERSE BRAKE SPRING

SPECIFICATIONS

. If not correct, replace spring(s).

LOW-REVERSE BRAKE SPRING SPECIFICATIONS

OIL PUMP

Disassembly

Remove pump cover retaining bolts and separate cover from pump body. Remove pump flange. See

Fig. 19

. If gears are to be reused, match

mark gears to reassemble in same position. Remove drive and driven gears.

Inspection

1. Check the condition of the gear teeth and surfaces. Check seal rings for signs of cracks or breaks and replace as needed. Check condition

of pump housing sleeve and inner gear bushing. See

Fig. 20

. See the

OIL PUMP SPECIFICATIONS

. Check sleeve outer diameter

and bushing inner diameter.

2. If sleeve diameter is less than 1.492" (37.90 mm) or bushing diameter is greater than 1.499" (38.08 mm) replace sleeve and bushing as a

set. Check pump clearances and compare with values shown in the

OIL PUMP SPECIFICATIONS

.

Reassembly

Apply ATF on all parts. To assemble, reverse disassembly procedure. DO NOT tighten pump cover to oil pump housing. Oil pump reassembly
is completed during transaxle reassembly.
