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.

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.
