Smooth riding a vehicle depends a lot on the gearbox.
Furthermore, it may be the last line incase of brake failure. Skillful use of transmission in complex and difficult circumstances, for example, ice or riding on heavy soil, allows the car to cope with them.
In order to always be confident in it, should regularly conduct technical PPC service.
In case of defective parts, they should be replaced immediately.
Remove and disassemble box gear. Details before inspecting, thoroughly clean the brush or scraper. Remove all debris and clean the holes and slots from possible dirt. Then rinse and remove all traces of oil. Blow parts with compressed air and wipe gently. Carefully blow bearings, making sure that there is no rotation of the ring.
Look at the cover and the transaxle case. The last should be no cracks in the nests of bearings for wear or damage. On the adjacent surfaces with covers and clutch housing also should be no defects that can cause lack of tightness and the divergence of the axes. Repair minor damage to a fine file. If you can not recover, replace parts. Check the condition of the front cover. Determine touch input shaft when it rotates. If this fact is the case, replace the damaged parts. Check the drain hole of the front cover, it should not be clogged, otherwise clean the plug.
Inspect the gaskets. At their working edges should not be nervousness and damage allowed wear on the edge of no more than 1 mm. In the case of minor damage - replace.
Inspect the trees. In Slots and working surfaces of the secondary shaft should be no damage or excessive wear. Flexible coupling must move freely in the slots. At the front end of the output shaft and input shaft in the bore on the running surface roughness visible needles should not be. On the intermediate shaft is not allowed excessive wear or pitting of the teeth. reverse gear axis should have a smooth surface without a trace of jamming. Small irregularities eliminate grit sandpaper M10-M40. In the case of large deformations and damage the shaft replaced.
Check gear. They are not allowed to wear their teeth or damage in excess of the allowable backlash in gearing. Pay attention to the condition of the ends of the teeth crowns on synchronizers. The work surface should be smooth and have visible signs of wear. Check the clearance between the gears meshed. Replace defective parts.
Inspect bearings. They have to be in perfect condition. Radial clearance should not be more than 0.05 mm. Squeeze the inner ring with your fingers to rotate the outer and one of them, rolling should be easy and smooth. Do not damage the surfaces on the balls or rollers and treadmills rings. Replace defective parts.
Check the plugs and rods. Not allowed deformation of shift forks. Stocks should move freely without clearance to the oil holes. Check the condition of the springs, the locking balls and crackers clamps. Replace damaged parts.
Inspect the clutch hub and the locking ringsynchronizers. Check the possibility of sticking to hubs enable transmission couplings. Pay particular attention to the coupling sliding surfaces. Check the ends of the coupling teeth. Significant deterioration of the surface of the locking ring are not allowed. Eliminate the malfunctions that impede the free slip, fine file. Replace defective parts.
