Low-Intermediate Servo
- Install spring from Low-Intermediate Servo Kit (T86P-70023-A). Install servo piston (without seal) and rod in case. Install servo piston gauge from kit and secure in case using servo cover bolts. Tighten bolts to 90 INCH lbs. (10 N.m). Tighten gauge screw to 30 INCH lbs. (3.4 N.m). See Fig 2 .
- Attach a dial indicator and position stylus through hole in gauge. Be sure stylus has contacted piston on a flat surface. DO NOT contact step on piston. Zero dial indicator.
- Back off gauge screw until piston movement stops and read indicator. The amount of piston travel indicated will determine rod length to be installed. Reading should be .216-.255" (5.5-6.5 mm). If a new low-intermediate band was installed, reading should be .196-.236" (5.0-6.0 mm).
- Install correct piston rod and repeat steps 1)-3). Install seals on piston. Install servo piston and spring being sure they are fully seated. Install new gasket, cover and bolts. Evenly tighten bolts to specification.
NOTE:
Be sure and align low-intermediate servo cover tab with port on case.
