Rear cover Assembly Mount the parts into the rear cover according to the following process: (a) Locate the rear cover on the suitable press machine, the coupling face of the rear cover shall face upward and parallel with the work face of the press machine. (b) Locate the needle bearing, of which the marked end facing upward, and press it in the rear cover until the upper end of needle bearing is 40.47 40.97 lower than the coupling face of the rear cover that matches with the front housing. (c) Press the ball bearing in the rear cover and mount the snapping ring well. (d) As for the electric shift transfer box, the parts shall be encased according to the following process: (1) Confirm the four O-rings are set on the clutch washer assembly (one O-ring is located on the coil, the other three on studs). Mount on the clutch coil assembly, of which the wire and stud shall protrude out the rear cover, take notice not to damage the wire when screwing up the nuts. Fastening torque (811)Nm (2) Encase the motor bearing and oil seal in the rear cover. (e) As for the electric shift transfer box, encase the as- sembled electric shifting cam group and clutch shell in the process as follows: (1) Put down the electric shifting cam group as shown in the drawing. (2) Hold the shift guide shaft downward and raise lightly the toggle fork assembly. Run the electric shifting cam group in place, so that the contact roller on deceleration toggle fork assembly enters in the groove of shifting cam, and the projecting part of lock toggle fork is at the rear end of the shifting cam, and then take reduce the component elements in the transfer box housing, meanwhile, joint the shift shaft on the pin in transfer box housing. (3) Locate the clutch shell well through the shift exter- nal gear sleeve and mount on the snapping ring. 8 |
