• As an alternative to the above measuring tool,
a tool used for pulling out the following
propeller shaft housing can be used to secure
forward gear (A gear).
• When performing the work, assemble propeller
shaft ass'y and housing ass'y and bolts to
tighten to specified torque.
Propeller Shaft Housing Bolt :
13 N·m ( 9 lb·ft ) [ 1.3 kgf·m ]
Puller Claw 1 :
P/N. 3AC-99736-0
Puller Plate 2 :
P/N. 3AC-99737-0
Center Bolt 3 :
P/N. 3AC-99738-0
Tightening Torque for Inspection :
Tighten bolt gradually until propeller shaft stops
to turn.
3. Perform shim adjustment as necessary based on the gauge
value obtained. The table shows relation between dial gauge
readings and shim adjustments.
1.Values in this table indicate dial gauge
readings that are obtained when using special
tool.
2.Add or remove shim(s) to adjust the thickness.
"+" means to add shim(s) and "–" means to
remove shim(s).
3. Check backlash measurements again.
Case example : Proper backlash ranges from 0.33 to
0.54mm of gauge reading, which means
that no shim adjustment is required when
backlash in within this range.
For example, if the gauge reads 0.85mm,
shim of 0.15mm is to be added.
