Early models (without reverse gear lock cable)
35. Set the gearbox to neutral and check that the levers on the box are in the correct position (see b/fig. 12.51). Due to the lack of main splines, it is quite possible to set the levers in the wrong position after disassembling the box.
36. Measure the length of the gear engagement rod and the gear selection rod and compare the values obtained with those shown in B / fig. 12.52. If necessary, adjust the length of the rods by loosening the locknut and screwing the rod into the threaded end (or turning her out of it) (ball joints must be disconnected).
37. Working in the cabin, disconnect the rubber boot of the gear lever and move it up the lever. Engage 2nd gear.
38. Measure the gap between the plastic cam and the stop in the shift lever housing. If the gap is not equal to that shown in B / fig. 12.53, remove the spring clip and lift the cam from its spline. Move the cam to obtain the desired clearance and secure it with a spring clip. Apply a little grease to the side of the cam where it rubs against the stop (see photo).
39. If, after adjusting the cam, 1st and 2nd gears are difficult to turn on, it is necessary to measure the stroke of the lever in the direction of the 1/2 gear plane.
40. Set the shift lever to neutral, then carefully move it to the left until resistance is felt.
41. Attach a ruler to the gear lever knob so that the zero mark is aligned with the 1/2 gear line on the knob.
42. Move the lever all the way to the left without moving the ruler, and measure the distance that the handle will move. Repeat this operation 2-3 times. The required amount of movement should be 38±2 mm.
43. If necessary, move the plastic cam (see above), to get the desired stroke.
44. If the cam is moved to the position corresponding to the maximum travel of the lever, but the required amount of travel has not been reached, it is necessary to lengthen the gear selector rod by 6 mm and measure the travel again.
45. If the cam is moved to the position corresponding to the minimum lever travel, but its travel still exceeds the required value, it is necessary to shorten the gear selection rod by 6 mm and check the lever travel again.
46. Upon completion of the adjustment, check the inclusion of all gears and make sure that the reverse gear cannot be engaged without lifting the ring on the lever.
47. Install and secure the rubber boot of the gear lever.
Latest Models (with reverse gear lock cable)
48. In 1985, a new type of gear lever mechanism began to be installed on the model in question. It can be recognized by the presence of the reverse gear lock cable.
49. A new type of gear lever mechanism does not require adjustment. The length of the engagement and selector rods is adjusted in the same way as indicated in paragraph 36.
Shift and select levers (models since February 1987)
50. Starting in February 1987, the shift levers and gear selectors are attached to the stems with cylindrical pins, and not with a key with a nut.
