2. Calculate the lower case standard(R/100).
S69j6585
NOTE:
• "R" A stamped on the trim tab mounting face
refers to the deviation of the lower case di-
mension from the standard. The numeral is
in 1/100mm.
• If the numeral is unknown, assume that “R”
is zero, and check the backlash when the unit
is assembled. Shimming shall be readjusted
if the backlash is out of specification.
3. Calculate the forward gear shim thickness.
Calculation formula:
Forward gear shim thickness
(T2)= M2 - 29.50 - R/100
Example:
If "M2"= 30.5, and "R"= -5, then :
T2 = 30.5 – 29.50 – (–5/100)
= 30.5 – 29.50 + 0.05
= 1.05
4. Select the forward gear shim(s) as follows.
Example:
If "T2" is 1.16mm, then the reverse gear
shim is 1.15 mm.
If "T2" is 1.20mm, then the reverse gear
shims is 1.18 mm.
Selecting the propeller shaft shims
NOTE:
Obtain the propeller shaft shim thickness(T4)by
using the specified measurement(s) and the
calculation formula.
Calculation formula:
Propeller shaft shim thickness
(T4) = 29.00 - A/100 + B/100 - M5
- M6
1. Measure the height of the roller bearing
outer race 1 from the inner race. (M5)
60h61660
NOTE:
Set the thrust bearing and the race on the roller
bearing, turn them two or three times to make
them seated properly.
Measure the bearing height at three points and
obtain the average.
2. Measure the thickness of propeller shaft
flange 4 and the thrust bearing 5 (M6)
