Additionally, if the chains in the tandem box are too slack, adjust the brake after
adjustment the chain tension to make the brake always assembled in the positions
(Point 3 and point 9) where the exhaust vent is located.
c. Disassembly (See attached figure)
○
1 Remove the exhaust vent assembly 7, and turn two locking screw 5 off on
one end of the clamps. Turn screw M10 to get the pin 6 out and remove
friction disc assembly 2.
○
2 Remove locking screw 5 on the other end to get the other pin out.
○
3 Record the positions of top and bottom caps. Screw the bolt 8 of cylinder cap
off, and get cylinder cap 9 off. Remove O-ring 10 from cylinder cap.
○
4 Push oil piston I out from the hole outside the clamp. Inside the hole remove
rectangular gasket 4 and dust-proof ring 11.
d. Inspection
○
1 Inspect friction discs of ht assembly for wear extent. Replace if the rear limit
which is mentioned above has been reached.
○
2 Replace if there is any damage on oil seal and dust-proof ring.
○
3 Clean the clamp (Use mineral oil).
○
4 Inspect the piston hole for scratches and corrosions. Replace the clamp if
there is any heavy damage.
○
5 Inspect the piston for scratches and corrosions. Replace if there is any

○
6 Replace if the pin is so worn that it cannot guide for friction discs.
e. Assembly
○
1 When assembling, all of the parts will be cleaned and it is forbidden to use
braking liquid;
○
2 Screwing torque for cylinder cam is 60N·m.
f. Inspection of braking performance
The braking performance is referred to the running safety and efficiency. After
repairing, the braking performance also should be inspected. The braking distance
can be considered as the constant braking index. On the straight and dry concrete
road, when braking speed is V=30km/h, the braking distance will be S
≤ 13.2km/h.
