7. Deceleration shift parts assembly
The mounting process is as follows:
(a) If the parts are taken apart for change, assemble the shift
toggle fork assembly with a new pin-contact roller
assembly. Press the pin-contact roller in the deceleration
fork hole until the detent passes the hole completely and
seizes the right location. Ensure that the contact roller can
run freely.
(b) Mount two inserted faces of toggle fork on the decelera-
tion toggle fork assembly.
(c) Engage the deceleration fork assembly and deceleration
gear sleeve and put them in the housing, and the decelera-
tion gear sleeve shall be put in the planetary mechanism
assembly that is assembled already. Mount the rear
output shaft and joint the bearings at the ends of output
shaft and input shaft as well as the spline of the gear
sleeve.
Remarks: the output shaft assembly can be delayed until the oil
pump is mounted on the output shaft. The oil pump may be
dipped into the lubricant through the oil pump screen, turn the
output shaft in clockwise from the output shaft direction to see
whether there is lubricant pumped out so as to check whether
the oil pump can work normally or not. The parts mounted
readily may be encased in the transfer box housing as an
assembly
8. Oil pump assembly
Ensure the parts of oil pump are completely lubricated when
assembling, and the oil can be pumped out from the conical
hole of the oil pump front cover. The mount of oil pump is as
follows:
(a) Mount the pin on the rear output shaft.
(b) Slide the oil pump assembly on the rear output shaft
along with the pin.
(c) Put the gripping hoop at the end of oil pipe that is
mounted on the oil nozzle of the pump housing, screw up

Washing, Checking, Up-Keeping and Exchanging (Washing)
1. Washing
Notice: check the metal rag around the magnet first before washing, large granule or irregular metal
granule shows the disintegratation or similar damage. Small or fine metal granule shows the uneven
or serious wear. If the metal rag is founded, notice shall be taken on damage and wear inspection
during checking the rotating parts and the element matched with the rotating parts.
(a) Common washing
Wash the parts in cleaning agent to clean away the old lubricant and deposit. Clean away the deposit in oil hole
with brush. Take notice not to scrape the metal coupling face when washing the parts cannot be cleaned with
brush.
(b) Dry the washed parts by blowing
Dry the washed parts by blowing the low-pressure compressed air (max pressure is 137.9kPa), because cloth
thread may be left during cleaning the parts with cloth. The bearing shall be held by hand to prevent it from
rotating when blowing it.
(c) Bearing lubrication
The ball bearing and needle bearing shall be lubricated with the lubricant for transfer box after washing. As
the non-lubricated bearing may cause damage when be dry. Cover the lubricated bearing to prevent dust
entering in.
