Auxiliary section
Same procedure for all aux sections, but spool assembly components may vary.
The spool assembly should already consist of the proper aux spool, 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
