1. Using Clutch Disconnect Tool (T88T-70522-A), disconnect hydraulic line at transmission. See Fig. 2 .
Clean reservoir cap area. Fill reservoir with DOT 3 brake fluid. Maintain fluid level in reservoir during
bleeding procedure.
2. Using small screwdriver, press and hold internal mechanism of male coupler to open valve. While
holding valve open, have an assistant slowly press and hold clutch pedal to floor.
3. Remove screwdriver to allow valve to close. Release clutch pedal. Refill reservoir.
4. Repeat steps 2) and 3). Install reservoir cap. Reconnect hydraulic line. Tug hydraulic line lightly to verify
secure connection.
5. As rapidly as possible, operate clutch pedal for full 5-10 strokes. Wait 3 minutes. Repeat this step at least
3 more times.
6. Loosen bleed screw, located next to release cylinder connection. Have an assistant press and hold clutch
pedal. Tighten bleed screw. Release pedal. Refill reservoir. Check clutch operation.

Submerge other end of hose in container of brake fluid.
2. Fill reservoir with DOT 3 brake fluid. Have an assistant press and release clutch pedal several times, then
hold pedal down. With pedal pressed, loosen bleeder screw to let air and fluid escape.
3. Repeat step 2) until no more air bubbles emerge from hose. Tighten bleeder screw. Fill reservoir. Operate
clutch while inspecting for leaks. Check clutch and brake operation.
REMOVAL & INSTALLATION
CLUTCH ASSEMBLY
Removal (B2300, B2500, B3000 & B4000)
1. Disconnect negative battery cable. Shift transmission into Neutral. Remove gearshift lever. Raise and
support vehicle. Mark drive shaft flanges for installation reference. Remove drive shaft. Using Clutch
Disconnect Tool (T88T-70522-A), disconnect hydraulic line at transmission. See Fig. 2
. Plug hydraulic
line to prevent contamination. Disconnect wiring at transmission.
2. Remove starter. Remove exhaust components as necessary for clearance. On 4WD models, remove skid
plate and transfer case. On all models, secure transmission jack under transmission. Remove transmission
mount-to-crossmember nuts and bolts.
3. Remove nuts securing crossmember to frame side rails, and remove crossmember. Lower transmission
enough to gain access to transmission-to-engine block bolts. Remove transmission-to-engine block bolts.
Remove transmission.
4. If clutch parts are going to be reused, mark clutch cover and flywheel for reassembly reference. Loosen
pressure plate bolts evenly in crisscross pattern until springs are not under tension. Remove clutch cover
and clutch disc.
Inspection (B2300, B2500, B3000 & B4000)
1. Inspect disc for loose rivets, worn or defective springs, excessive wear, or oil contamination. Inspect
flywheel and clutch cover for burns, scoring, or grooves.
2. Measure flywheel and clutch cover runout. Resurface or replace flywheel and clutch cover if beyond
specification. See CLUTCH RUNOUT (MAXIMUM)
table.
3. Measure clutch disc runout. Replace disc if it is not to specification. See CLUTCH RUNOUT
(MAXIMUM) table. Inspect disc hub and input shaft splines for excessive wear. Hub must slide
smoothly on input shaft splines.
4. Inspect pilot bearing for wear. Apply inward pressure while rotating pilot bearing. If bearing sticks or has
excessive resistance, replace bearing. Check for tight fit in crankshaft. Replace as necessary. Inspect
release bearing for smooth operation, wear, damage, or looseness. Replace bearing as necessary.

GENERAL INFORMATION
Computer Relearn Procedures
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may require a relearn procedure after vehicle battery
is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum
driveability and performance. When vehicle battery is disconnected, this memory is lost. The computer will use
default data until new data from each key start is stored. As computer memorizes vehicle operation for each
new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during relearn stage because vehicle acts differently then
before being serviced. Depending on type and make of vehicle and how it is equipped, the following complaints
(driveability problems) may exist:
Harsh Or Poor Shift Quality
Rough Or Unstable Idle
Hesitation Or Stumble
Rich Or Lean Running
Poor Fuel Mileage
These symptoms and complaints should disappear after a number of drive cycles have been memorized. To
reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle
should be road tested.
GENERIC COMPUTER RELEARN PROCEDURES
Some manufacturers identify a specific relearn procedure which will help establish suitable driveability during
relearn stage. These procedures are especially important if vehicle is equipped with and electronically
controlled automatic transmission or transaxle. Always complete procedure before returning vehicle to
customer. The following general procedures are to be used if driveability problems are encountered after power
loss or battery has been disconnected. These procedures may provide an aid in eliminating these problems.
Automatic Transmission
Set parking brake, start engine in "P" or "N" position. Warm-up vehicle to normal operating temperature
or until cooling fan cycles.
Allow vehicle to idle for one minute in "N" position. Select "D" and allow engine to idle for one minute.
Accelerate at normal throttle position (20-50%) until vehicle shifts into top gear.
Cruise at light to medium throttle.
Decelerate to a stop, allowing vehicle to downshift, and use brakes normally.
Process may be repeated as necessary.

Manual Transmission
Place transmission in Neutral position.
Ensure emergency brake has been set and all accessories are turned off.
Start engine and bring to normal operating temperature.
Allow vehicle to idle in Neutral for one minute.
Initial relearn is complete, and process will be completed during normal driving.

Removal (MPV)
1. Raise and support vehicle. Remove rear wheel and tire assembly. Remove brake caliper and support
aside. Remove brake disc plate. See Fig. 5
. Using dial indicator, measure axle bearing play. Replace axle
bearing if play exceeds .023" (.57 mm).
2. Remove hold pin from parking brake shoe assembly and remove parking brake shoe assembly.
Disconnect parking brake cable. Using Flare Nut Wrench (49-0259-770B), disconnect brake pipe. Plug
brake pipe openings.
3. Remove rear axle shaft assembly-to-axle shaft housing retaining nuts. Using Puller (49-0223-630B) and
Attachment (49-8501-631A), remove rear axle shaft, backin
