Dongfeng Military Truck Adjustment and Maintenance - Adjustment of Chassis and Common Troubleshooting - Gearbox

The second quarter Gearbox

First, Gearbox Adjustment of the manipulation

EQ2102G belongs to the double-type manipulation mechanism, due to the larger, the middle conversion bracket is more, in assembly, the adjustment time is more, and therefore the following points should be noted when adjusting:

1. In the assembly, the position and assembly length of the selection, shift lever joints should not be changed.

2, the swing arm on the support should be substantially located in the vertical direction, can not be offset too much (refer to the position of the gear position), otherwise adjust the size of the corresponding other, the shift lever until satisfaction

3. If there is no selection operation, the cab can be turned to the cab, check the shift holder assembly on the cab floor with a selection ball, the ball head is stretched in the arms There is a plastic ball bowl on the head. If this plastic ball bowl is damaged, the ball is in the ball box of the ball box, which will cause the elective trip to be too large.

4, the entire rod system cannot be squeezed with other systems, otherwise interference occurs.

5, if the phenomenon of the armband or the lever position is not satisfactory, the maximum two trip rods (No. 3) in the steering mechanism can be adjusted, and the thread thread threads are threaded on both ends of the rod. Loosen the lock nut, turn the rod Adjustment purposes can be achieved: the quantity of the two trip rods is 10mm;

Acceptable gear rod, shift lever length (mm)

Secondary gear transmission mechanism principle

Second, common faults

1. Optional file, change difficulty

   1) When the shift rod is adjusted.

   2) The clutch separation is not thorough.

   3) The shift lever is removed from the groove and shifting the bar.

   4) Fork deformation or damage.

   5) The synchronizer fails or damaged.

2. Chart

   Most of the reasons for the chaos are due to the failure of interlocking mechanisms, and should be cleaned and inspected on the Gearbox cap.
