CLUTCH REPAIRS.
ASSEMBLY AND ADJUSTING THE DRIVE CLUTCH

Before assembly, all parts of the main cylinder and working closely Rinse with fresh alcohol or brake fluid. Mirrors Desktop and the main cylinder, wipe with a clean cloth dampened with in alcohol or brake fluid and inspect them, preferably with illumination. If the mirrors are small cylinders of corrosion, minor scratches or wear, scuff the cylinder, or a mirror othoninguyte it. At the same time allowed an increase in diameter cylinders up to 22.17 mm. In this case, the assembly, use Standard (new) rubber sealing cuff. As a rule, uniform wear of working surfaces of the main and clutch slave cylinder has no significant effect on the performance, clutch, as sealing sleeves are installed in cylinders with a significant interference fit, so the wear of friction pair components is compensated the elasticity of the cuff. In the presence of shells in the cylinder bores, replace with new ones. Rubber sealing cuffs, pistons and cylinders in front of mirror assembly grease with castor oil or fresh brake fluid. When cleaning the working cylinder, remove the dirt from the sharpened match groove at the bottom of the cylinder. Even the tiniest particles of dirt, falling under the collar after assembly, can cause leaking and missing the air. Also clean the hole for supplying a liquid. Inspect the threaded holes in the cylinder, threaded fitting in the master cylinder. Cut and crumpled thread is not allowed. If cuff or have hardened on the edges of workers defects, replace them. If the protective rubber covers hardened covered with cracked or broken off, and replace them. In the master cylinder gently clean the bypass B (see Fig. 67) outlet openings pointed match, and wear With the hole - a soft blunt wire -0.6 mm. Also Clean the vent hole in the tube filling tank. The connecting pipe between the master cylinder and work well thoroughly wash and rinse. Peruse connecting cones and thread fittings. Dimensions of all capillary tube after expanding shown in Fig. 73. Check to see whether the tie loosened and the return springs. Efforts they must conform to Table. 9. If the springs are weak, replace them. It is recommended to examine the ends of plastic sleeves and the presence of burrs on the ends gently clean them. 1.Sborku worker and the main cylinder produce cohesion in the reverse order to that specified in Sec. "Removal and disassembly of the drive clutch" (§ § 13, 14 - for the working cylinder, and in § § 7.11 - for the main clutch cylinder) with the following additional Guidelines: after assembly of all parts of the master cylinder clutch check Do vigor comes back under the action of the piston return Spring to lock in a thrust washer 12 (see Fig. 67) after a full press on it a pusher, and there is in the initial position (piston rests on the thrust washer) clearance between the spherical head and the socket pusher piston. Absence and the gap is unacceptable. Its value of 0.2-1.0 mm provided the size of incoming parts. If the piston sluggish returns to its original position after a full pressing the pusher on it, check the elasticity of the return spring (Data for the spring are shown in Table. 9). If the spring has lost elasticity, replace it; making a full withdrawal of the piston, check with a soft wire - no more than 0.6 mm, the wear is not covered if the hole On the edge of the cylinder piston sleeve 16. If it is closed, Disassemble the cylinder, determine the cause and eliminate overlapping holes it. If necessary, replace defective parts, after then perform final assembly of clutch master cylinder; if dismantling the cylinders were turned out of the flange bolts 6, Wrap them in a flange, to bear the size of 18-19 mm from the end flange to protruding end of the stud. 2.Soberite the clutch pedal by inserting both sides of the hub of a plastic sleeve to lock it into fillets ends of the hub. Prior to delivery, the inner surface lubricate the bushings thin layer of grease LSZ-15 or graphite lubricant. On the outer diameter of the hub wear snatch spring 21 (see in Fig. 56), and the platform pedals - the rubber pad 22. 3.In the opening bracket, insert the upper end clutch pedal, the holes in the bracket with a hole in the cheeks hub pedals and a small hook spring resting on the cheek bracket. 4.Legkimi hammer blows xtextolite paste axis of the pedal all the way into the opening bracket, aligning the first wrench flats on the axis of figure with flat holes in the bracket, then zashplintuyte it. Check the easy swing to the pedals a fixed axis. Under the action of the spring to the pedal vigorously to return to its original position. 5.Ustanovite clutch slave cylinder on the engine, and then paste it into the cylindrical bore tide clutch housing so that the cylinder of his special pad rested on the bottom end of the cylinder. Then fix it on the displacement in the axial direction of the locking ring 31, which is installed in the groove on the outer diameter cylinder with special kruglogubtsev. 6.Vozmite plunger 27 fork assembly and insert its rounded end into the recess of the working piston of the cylinder, and then the tip of the pusher 26, insert the plug off traction. The length of the pusher assembly with the tip should be approximately Of 105 mm. Then put the snatch spring 20 (see Fig. 54) at one end the hole in the clutch housing and the other in the slot the forks. 7.Otreguliruyte, as indicated below, the free outer end w clutch fork, ravii 4.5-5.5 mm. The indicated value freewheel Wiley corresponding magnitude of the gap S podshila between the ball and the fifth (the gap S is equal to about 2.5 mm), set with adjustable length pushrod (See Fig. 56) clutch fork. Pre-determine the value of the plug 5 is moved (Fig. 74) with respect to the tip 4. To do this, move the plunger 2 to the left of the working piston Upolu cylinder and push the plug 5 to either nechniku rod in a direction the opposite direction X - the first position. Next, move the tip of the plug relative to the direction arrow X to lock the bearing to the second position. Movement the end of the fork from the first position to the second should be 4.5-5.5 mm. If it is less than 4.5 mm, cut the pusher, and if the gap more 5.5 mm, lengthen the pushrod forks. After adjustment, tighten the locknut 8.Vstavte the outside of the shield in front of the car punched holes in it pins in the clutch master cylinder assembly. 9.Ustanovite on pins 6 (see Fig. 56) Bracket with a clutch pedal assembly nuts and profit 5 with planted washers. The upper part of the bracket is bolted to the 9 planted washer. Bottom of the mount nuts. 10.Soedinite 15 foot finger grip 16 with pusher piston master cylinder 12 so that the head pin was on the left with respect to the pedal (in the course of the car). Then put on washer 17 on the protruding end of the finger, zashplintuyte it. 11.Proverte complete with respect to the clutch pedal RF Input of the way into the floor mat, which should be is equal to 150-155 mm. If necessary, perform adjust the starting position the clutch pedal. Adjustment by varying the length of the plunger 12 by means of its vvertyvay or screwing out of the tip 14. To increase the lengthen the stroke pedal pusher, ie Remove the plug from the ero, for reduce speed - shorten the pusher, then screw it in there the tip. After finishing the adjustment of the pedal a reliably secure plunger from turning, tighten it a nut 13. Care should be taken to the site and the clutch pedal brake pedals were on the same level as the difference between the levels must be no more than 5 mm. 12.Predvaritelno washed with fresh alcohol or brake fluid connecting tube melzhdu main cylinder and working to installing a car blow compressed the air. Then connect the lower end of the tube with the working cylinder by tightening the threaded hole of the cylinder connection nut to failure. 13.Prisoedinite upper end of the connecting tube to the main clutch cylinder, wrapped in a threaded hole nozzle the master cylinder coupling nut before failure. 14.Zapolnite clutch system with fresh special brake fluid. Not allowed to mix brake fluids different brands, as well as adding to the system at least very small amount of mineral oils, gasoline, kerosene, as they cause the destruction of rubber parts. Keep in mind that brake fluid stains on the leaves painted surfaces and other body parts. After filling the system with liquid, remove it from the air the following sequence: Fill the tank with liquid to a level between the diametral ring on the body of a tank (see Fig. 67); removing the protective cap 8 (see Fig. 70), wear the crown Valve rubber hose. The free end of the hose to soak brake fluid, poured into a clean glass jar; sharply tap your foot on the clutch pedal is consistently 2-3 times (With an interval between presses 1-2), and then, leaving the pedal pressed to loosen the valve 7 1/2-1 turn release the air. Under the pressure created in the system, the liquid and contained in it come out the air through a hose into the vessel with fluid (air from the hose will come out as bubbles); after the liquid will flow from the hose, tighten the valve venting to failure; Repeat the operation until such time as full stops release of air from the hose submerged in a vessel with liquid (It takes up to 75-80 pedal). When pumping systems do not allow the reduction in nutrient tank for more than two thirds of normal size. After termination of the hose out of the air bubbles, hold pedal is depressed, tighten up the valve failure, then remove the hose, Put on the head of the valve cap and top up liquid in the feed tank to normal levels. After pumping Click to failure on the pedal and measure the value of movement of the pusher, it must be not less than 19 mm. At a lower value - continue pumping until the complete removal air from the system and obtain the necessary movement of the pusher. For a complete filling of clutch requires approximately 150 grams of brake fluid. Properly pumped system Clutch must provide a shock-free reverse gear in the gearbox. If the all the way down to the floor the clutch pedal there is a shock reverse gear is engaged, you should verify the accuracy of installation of the free outer end of the course forks off coupling (see section 7) and the serviceability of the mechanism of adhesion. 15.Pri down all the way to the floor, check the clutch pedal tightness of the main tube and the working cylinder. In case of leakage of fluid tighten the connection nuts to eliminate leaks. 16.Pustite engine and press several times on the clutch pedal to the lock it into the floor mat. At the same time should not be detected seizure, knocks, noises or other defects. Москвич-412 Москвич-412
