Inspection (Miata) 

1. Inspect disc for loose rivets, worn 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. If flywheel ring gear is replaced, ensure 
chamfer on flywheel teeth faces engine.  

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.

Installation (Miata) 

1. Lightly coat input shaft splines, release bearing, and fork contact areas with molybdenum disulfide 

grease. Align clutch cover dowel holes with flywheel dowels. Tighten clutch cover bolts evenly in a 
crisscross pattern to specification. See TORQUE SPECIFICATIONS .  

2. Place a wooden block on jack, and position jack under front of oil pan. Raise front of engine to ease 

transmission installation. Install transmission. Tighten transmission-to-engine block bolts to specification. 
See TORQUE SPECIFICATIONS . Place jack (from front of engine) under transmission.  

3. Raise transmission until level with engine. Position Power Plant Frame (PPF) in place. Install 

PPF/differential mounting spacer, and tighten bolts to 27-38 ft. lbs. (37-51 N.m). Install and tighten PPF 
side mounting bolts. 

4. Install sleeve into PPF housing block. Install spacer and bolts. Install reamer bolt into front hole, and 

tighten bolt. See Fig. 5 .  

5. Install transmission-to-PPF bracket. Install remaining PPF bolts, and tighten to specification. See 

TORQUE SPECIFICATIONS . To complete installation, reverse removal procedure.  

RELEASE BEARING & FORK 

Removal (B2300, B2500, B3000 & B4000) 

With transmission removed, twist release bearing and carrier assembly until preload spring pushes bearing
