Inspection (Tacoma - 2WD)
- Check wear on facings of clutch disc by measuring depth of each rivet head. Minimum depth at any rivet is .012" (.30 mm). Check clutch disc runout. Maximum runout at facing on clutch disc is .031" (.80 mm). Replace clutch disc if not within specification.
- Using a dial indicator, check flywheel runout. Replace flywheel if flywheel runout is greater than .004" (.10 mm).
- Using a caliper, measure depth and wear on diaphragm spring on clutch cover. See Figure. Maximum depth is .024" (.60 mm) and maximum width is .197" (5.00 mm). Replace clutch cover if necessary.
- Turn release bearing while applying axial force and ensure clutch release bearing rotates smoothly. Turn pilot bearing at end of crankshaft while applying force in direction of rotation and ensure pilot bearing rotates smoothly. Replace clutch release bearing or pilot bearing if bearing sticks or has much rotational resistance. If it is necessary to replace pilot bearing, see PILOT BEARING .
- After clutch cover installation, using a dial indicator, check diaphragm spring tip runout. If diaphragm spring tip runout is greater than .020" (.50 mm), adjust clutch cover spring tips using Tip Adjustment Tool (09333-00013).
