To prevent drive adjustment failure, when performing work related to disconnecting its elements, mark the relative position of the parts in advance in any available way. When reassembling, install the drive elements in accordance with the marks applied.
If the drive adjustment is slightly disturbed and the gears engage, albeit with difficulty, then if the performer has some skills, he can try to restore the adjustment by trial and error.
Loosen the tightening bolt of the clamp that secures the transmission control rod to the transmission lever and by moving the rod slightly along the lever, ensure that the gears are engaged clearly. If 1st and 2nd gears are not selected clearly, turn the rod slightly counterclockwise relative to the lever (if you look at the drive from the engine side). If the 5th gear and reverse gear are not clearly selected, turn the rod clockwise. If they are clearly selected, but are difficult to engage (or don't turn on at all) 1st, 3rd and 5th gears, move the rod along the lever forward in the direction of vehicle movement without turning it relative to the lever. If 2nd, 4th and reverse gears do not engage clearly, move the rod back along the lever. After each movement of the rod along the lever, tighten the clamp clamp bolt and check the adjustment result. If necessary, repeat the adjustment until the desired result is achieved.
