PROCEDURES
Calculating Thickness Of Last Outer Plate -A-





- The thickness of the outer plate is determined by gap "x, and is selected from table below.

Gap x = a - b - 3.2mm
A - Outer plate

NOTE: First outer plate -arrow- is always 3 mm thick

Calculating "a":





- Clutches installed, refer to Planetary Gearbox Disassembly/Assembly. Service and Repair
- Measure from pump flange/housing to last inner plate with depth gauge "A".

Example:

Reading for "a" = 30.2 mm

Calculating "b":





- Place straightedge "B" onto stator support (arrow) and measure with depth gauge "A" to gasket of pump flange.

Example:

Reading minus Straightedge Thickness equals Calculated size b

40.1 mm - 19.5 mm = 20.6 mm

Calculating and Selecting Thickness Of Last Outer Plate

Gap x = a - b - 3.6 mm
= 30.2 - 20.6 - 3.2 = 6.4 mm

2nd And 4th Gear Brake Table Of Plates:

- Determine thickness of outer plate according to table above:
- Determine thickness of outer plate according to table and obtain from parts supplier..
Two outer plates can be installed.
