We thoroughly wash all parts in kerosene or diesel fuel and inspect them. The teeth of gears and couplings should be free of chips, scoring, fatigue chipping and noticeable wear. The surfaces of shafts, axles and shift rods must be completely smooth, free from scoring, pits and severe wear. There should be no cracks or nicks on the crankcase, and there should be no wear or traces of turning in the bearing bores. Corrosion and traces of crushing and galling are unacceptable on the shaft splines. Minor damage can be repaired with fine sandpaper followed by polishing, but it is better to replace damaged parts with new ones.
All rolling bearings, both ball and roller, must be in perfect condition, their radial play must not exceed 0.05 mm, any defects on the tracks and rolling elements are unacceptable. Separators should not have breaks, touching rings and melting (for plastic ones). In general, if the "mileage" of the box exceeds 120 thousand km and the unit is being repaired with disassembly, it is better to replace all bearings with new ones, regardless of their condition, especially if severe damage to gears and gear clutches was noticed. We replace the cuffs with new ones in any case. When assembling, we lubricate all the parts of the box, incl. the bearing seats and the bearings themselves with transmission oil, the joints of the crankcase and covers are covered with a thin layer of oil-resistant sealant, and the parts of the switching mechanism are coated with SHRUS-4 grease.
We assemble the gearbox in the reverse order of disassembly. The spring of the reversing fork rod retainer is different from others in stiffness and has a black coating. Before installation, the working surface of the cuffs is coated with a thin layer of Litol-24 grease. We tighten the bolt of the intermediate shaft bearing clamping washer with a torque of 8.1–10.0 kgf.m. We tighten the nut of the rear end of the secondary shaft with a torque of 6.8–8.4 kgf.m.
On the VAZ 2106, four and five-speed gearboxes are installed (hereinafter referred to as gearbox). The five-speed box is made on the basis of a four-speed box, both units are interchangeable, the main parts are the same.
Our manual will clearly show you how a five-speed VAZ 2106 gearbox is repaired - we begin the repair with a fault diagnosis.
Malfunctions in which box repair is necessary.
- Worn bearings;
- Worn gear teeth or synchronizer teeth;
- The shafts in the housing loosened; during operation, their axial displacement occurs.
- The spherical hinge of the lever is worn out, there is no lubricant in the switching unit;
- The shift lever is deformed;
- (rods) burrs, deflections have arisen, rod seats are dirty, blocking crackers are jammed;
- The splines of the coupling or the splines of the hub are clogged;
damaged shift forks.
- The holes for the balls or the balls themselves on the rods were worn out, the springs of the retainers broke;
- The blocking ring on the synchronizer is worn out;
- The synchronizer springs have broken;
- Worn teeth of synchronizer couplings or ring gear.
- The shaft seals of the box are worn out;
- The fastening of the gearbox covers to the body is loose, the sealing gaskets are damaged;
- The fastening of the clutch housing to the box body is loose.
Warning: The listed malfunctions are caused by other reasons, for the elimination of which it is not necessary to remove and disassemble the gearbox. Since the removal and disassembly of the gearbox are very laborious processes, be careful when diagnosing faults, be sure to make sure that such a repair is necessary.

Before assembly, we rinse all parts with white spirit or kerosene and blow with compressed air. We wash and blow through the bearings with compressed air. We inspect and replace worn parts. The parts should be free of damage and traces of excessive wear, and on the mating surfaces of the parts there should be no scuff marks.
The crankcase walls must be free of cracks, and the bearing seats must be free of signs of wear or damage. The contact surfaces of the connectors of the gearbox housing, clutch housing and rear cover must not be damaged, causing divergence of the shaft axes and insufficient tightness.
Damage or excessive wear of sliding surfaces and splines is not allowed on the shafts. Minor surface irregularities may be removed with fine-grained emery paper; if there are large damages or deformations, the shaft must be replaced with a new one.
The bearings should show no signs of destruction of the tracks, cages, balls or rollers; when the bearing rings are turned, the rolling should be smooth.When repairing gearboxes with significant mileage (100 thousand km or more), it is advisable to replace all bearings with new ones, regardless of their current condition.
Excessive wear and chipping of gear teeth and synchronizers are not allowed, the working surface of the teeth must be smooth.
Also, deformation of the forks for engaging gears is not allowed, the rods of the forks must slide freely without a significant gap in the holes in the crankcase.
There should be no traces of binding on the hubs of the gear clutches.
The friction surfaces of the locking rings must be notched. In case of wear of the notch, replace the locking ring with a new one.
