2001 Toyota Tundra Parts Questions & Experts Answers

• Q: How to service and repair the starter motor on 2001 Toyota Tundra?

  A: Service and repair operations on the starter motor should start with a process of disassembly that includes removing the nut and disconnecting the lead wire from the magnetic switch terminal at 5.9 N.m (60 kgf.cm, 52 in.lbf) before extracting the 2 through bolts at 5.9 N.m (60 kgf.cm, 52 in.lbf) for 1.2 kW and 1.4 kW versions and using 9.3 N.m (95 kgf.cm, 82 in.lbf) for 1.8 kW versions. Reassemble the magnetic switch assembly by aligning both the field frame protrusion and the cutout as you reintroduce the field frame with armature assembly. The O-ring needs removal before installing a new one as part of assembly. To continue disassembly you should remove two housing screws applying the same torque values as during the first step. After that remove the starter housing and its components which include the return spring, bearing, idler gear, and clutch assembly. The procedure calls for using a magnetic finger for steel ball retrieval from the clutch shaft opening. The brush holder requires 2 screw removal with specified torque settings for both 1.2 kW / 1.4 kW at 1.5 N.m (15 kgf.cm, 13 in.lbf) or 1.8 kW at 3.8 N.m (38 kgf.cm, 34 in.lbf) to separate the end cover and O-ring before dissembling the 4 brushes. Reassemble the parts in the opposite order while applying high-temperature grease on bearings, gears, return spring, and steel ball. Special Service Tool: 09286-46011 provides necessary functions to remove existing rear and front bearings before pressing in new bearings which must face their correct direction. The magnetic switch terminal kit repair requires removal of magnetic switch end cover before evaluating contact plate wear (0.9 mm (0.035 in.) maximum) and necessary component replacement. The installation requires Special Service Tool: 09810-38140 for terminal nut loosening followed by precise part replacement from terminal C and terminal 30 with correct positioning of terminal insulators. The terminal nuts should be tightened first to 17 N.m (170 kgf.cm, 13 ft.lbf) with 981 N (100 kgf, 221 lbf) of force using a wooden press block sized at 20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.) which prevents contact plate tilting. Reinstall the plunger together with a new gasket while tightening the 1.8 kW type lead clamp (3 bolts) to 2.5 N.m (25 kgf.cm, 22 in.lbf) and the 1.2/1.4 kW types to 2.5 N.m (25 kgf.cm, 22 in.lbf).
