Press new needle bearings, the outer ring of the upper bearing of the worm shaft and new oil seals into the steering gear housing.
Assemble the steering gear housing cover by adjusting the gap between the adjusting screw and the bipod shaft as follows. Turn off the adjusting screw until a gap of 0-0.05 mm is obtained between it and the bipod shaft. Tighten the locknut and recheck the clearance.

Install the worm shaft assembly with the bearing separators into the crankcase and press the outer race of the thrust bearing to the stop. Measure the value «A» sinking of the outer ring of the thrust bearing relative to the plane of the crankcase (let's say it is 1.35 mm). Measure thickness «IN» thrust disc washer (pos. 10 in the picture), which, for example, is equal to 1.50 mm. Determine thickness «WITH» installed shims according to the formula B-A \u003d X:
C \u003d 1.50 - 1.35 \u003d 0.15 mm.
Install turning tool 7015 on the worm shaft and, turning the worm shaft, gradually tighten the bolts for fastening the lower crankcase cover to a torque of 2.2 + 0.2 kgf·m.
Measure the friction torque of the worm shaft and, if necessary, install thicker shims.

Insert the bipod shaft into the crankcase and gradually tighten the top cover bolts to the required torque (before assembly, apply Atmosit type sealant to the gaskets of the covers).
Fill the steering gear housing with oil and set the steering gear to the straight-line position, aligning the marks on the housing and the bipod shaft.
Measure the moment of friction of the bipod shaft. If abnormal, adjust the gap between the adjusting screw and the arm shaft by loosening the adjusting screw lock nut.
Check dimensions «A» And «IN» bipod (see picture), which should be 112.5±0.5 and 26 mm, respectively, and put the bipod in place along the alignment marks.
