Idler Gear
DISASSEMBLY
1. INSPECT IDLER LOW GEAR RADIAL AND THRUST CLEARANCE
a. Using a feeler gauge, measure the idler low gear thrust clearance.
Standard clearance: 0.125 - 0.275 mm (0.00492 - 0.01083 inch)
Maximum clearance: 0.275 mm (0.01083 inch)
b. Using a dial indicator, measure the idler low gear radial clearance.
Standard clearance: 0.015 - 0.068 mm (0.00059 - 0.00268 inch)
Maximum clearance: 0.068 mm (0.00268 inch)
2. REMOVE FRONT TAPER ROLLER BEARING
Using SST, remove the front taper roller bearing.
SST 09950-40011 (09951-04010, 09952-04010, 09953-04030, 09954-04010, 09955-04061, 09957-04010, 09958-04011), 09950-60010 (09951-00330)
NOTICE: Set the claw of SST to the bearing inner race securely.
3. REMOVE REAR TAPER ROLLER BEARING
Using SST, a press and socket wrench, remove the rear taper roller bearing.
SST 09950-00020
NOTICE: Set the claw of SST to the bearing inner race securely.
4. REMOVE IDLER LOW GEAR AND NEEDLE ROLLER BEARING FROM IDLER GEAR
5. REMOVE HIGH AND LOW CLUTCH SLEEVE FROM IDLER GEAR
INSPECTION
1. INSPECT IDLER GEAR
Using a micrometer, measure the idler gear diameter.
Standard diameter: 38.48 - 38.50 mm (1.5149 - 1.5157 inch)
Maximum diameter: 38.50 mm (1.5157 inch)
2. INSPECT IDLER LOW GEAR
Using a cylinder gauge, measure the idler low gear diameter.
Standard diameter: 45.52 - 45.54 mm (1.7922 - 1.7930 inch)
Maximum diameter: 45.54 mm (1.7930 inch)
REASSEMBLY
HINT: Coat all of the sliding and rotating surfaces with gear oil before reassembly.
1. INSTALL FRONT TAPER ROLLER BEARING
Using SST and a press, install the front taper roller bearing.
SST 09316-60011 (09316-00011, 09316-00031)
2. INSTALL HIGH AND LOW CLUTCH SLEEVE
HINT: Make sure to install the high and low clutch sleeve in the correct direction.
3. INSTALL NEEDLE ROLLER BEARING AND IDLER LOW GEAR TO IDLER GEAR
a. Apply gear oil to the needle roller bearing.
b. Install the needle roller bearing and idler low gear.
4. INSTALL REAR TAPER ROLLER BEARING
Using SST and a press, install the rear taper roller bearing.
SST 09316-60011 (09316-00011, 09316-00071)
5. INSPECT IDLER LOW GEAR RADIAL AND THRUST CLEARANCE
