Tilt section
The spool assembly should already consist of the tilt spool(with tilt plunger and spring inserted
into the bore on the spring end), the return spring, one spring seat on either end of the spring, the
seal plate, a spool seal, and a dust wiper. All of these are assembled on the end of the spool
opposite the clevis.
Insert the clevis end of the spool into the right-hand side of the spool bore(the tallest end of the
housing). Place the spool cap over the spool and spring assembly and connect the cap to the
housing using two bolts. Torque both bolts alternatively until a torque of 1.0~1.5kgf

Install the second spool seal and dust wiper over the clevis end of the spool and retain with a seal
plate and two bolts. Torque both bolts alternatively until a torque of 1.0~1.5kgf
