Component Inspection
COMPONENT INSPECTION^ Check each ball bearing for smooth rotation. If found abnormal, replace.
^ Check each spring for distortion or breakage and change it with new one as necessary.
^ Especially for locating springs (1), measure each free length "a" and replace if it is below service limit.
Locating spring free length "a"
Standard 19.5 mm (0.768 inch)
Service limit 18.0 mm (0.709 inch)
^ Check needle bearing and bearing contacting surface for damage. Replace as required.
^ Check gear tooth surface and shift mechanism in the same manner as with transmission. Correct or replace as necessary.
^ Check drive chain and sprockets for abnormal wear or damage. Replace as required.
^ Check oil seal for leakage and its lip for excessive hardness.
If either is found, replace.
Also, check corresponding surface of shaft where oil seal lip contacts. Correct or replace as necessary.
^ Check gear tooth surface of speedometer drive gear. Replace if it is damaged.
^ Put the synchronizer outer ring (1), inner ring (3) and the cone (2) together and then measure the step difference "b" between the outer ring (1) and the inner ring (3). And also check key slot or boss width "c" in synchronizer outer ring (1) and each chamfered tooth of gear and synchronizer ring and replace with new one, if necessary. Also, check gear tooth.
Difference "b" between the outer ring and the inner ring
Standard: 1.0 - 1.4 mm (0.039 - 0.055 inch)
Service limit: 0.5 mm (0.019 inch)
Slot or Boss width "c" in synchronizer outer ring
Standard: 10.1 mm (0.397 inch)
Service limit: 10.4 mm (0.409 inch)
^ Check chamfered part of each sleeve (1) for damage and excessive wear, and replace as necessary.
^ Using feeler gauge, check clearance "d" between sleeve (1) and shift fork (2) and replace parts if necessary.
Clearance "d" between sleeve and shift fork: Maximum 1.0 mm (0.039 inch)
^ Check each synchronizer key and synchronizer spring and replace as necessary.
^ Check splined portions and replace parts if excessive wear is found.
