UNDERCARRIAGE TMS800E SERVICE MANUAL
If not absolutely sure of correct bolt-to-piston engagement,
repeat step 5 until sure.
5. Turn the release-bolt 1/4 turn clockwise and pull the bolt
out to lock the formed end into the piston. If the bolt does
not lock into the piston in less than 13 mm (1/2 inch)
outward movement, repeat steps 4 and 5 until it locks.
6. Holding the bolt locked into the piston, install the
flatwasher and the release nut on the end of the release-
bolt, and turn down the nut against the flatwasher until
finger tight (Figure 8-40).
7. Using a 3/4 inch hand wrench turn the release-nut
clockwise until 8.2 cm (3.25 in) length of bolt extends
above the nut (Figure 8-41). Do not use an impact
wrench.
8. For easier manual-releasing, apply 6.2 - 8.6 bar (90 -
125 psi) air pressure to inlet port marked “SPRING
BRAKE” before step 4, but make sure to exhaust all air
pressure after step 7 and 8.
9. To reactivate the piggyback/spring brake from its
manually-released position, reverse the order of steps 8
through 1.
10. When re-installing the release-bolt, flatwasher and
release-nut into the storage pocket, apply 13.5 Nm (10
lb-ft) torque on nut against the flatwasher (Figure 8-42).
CAUTION
Do not exceed the length as stated in step 7. Do not
exceed 67.7 Nm (50 lb-ft) torque on release nut at any
time or damage may occur which could prevent any future
correct manual-releasing of the piggyback spring brake
chamber.
