Transmission, Installing
Installing
-- Install the manual transmission together with the bevel box.
Refer to "Transmission, Removing" to get a list of the special tools needed. Refer to TRANSMISSION, REMOVING, AWD .
Replace self-locking screws and nuts after removing them.
Replace bolts that were tightened with an additional turn after removing them.
Install any cable ties that were loosened or cut off during removal at their same location.
Clean the input shaft splines and (on used clutch plates) the hub splines. Remove any corrosion and then apply a very thin coat of Grease for Clutch Disc Shaft Splines: G 000 100 on the splines. Then move the clutch plate back and forth on the input shaft until the hub moves freely on the shaft. Excess grease must be removed.
-- If the transmission is replaced, transfer the transmission shift lever and the selector relay lever.
-- Clean all threaded holes for self-locking bolts with a thread tap to remove any locking fluid residue.
-- The alignment sleeves for centering the engine/transmission must be present inside the cylinder block. Install them if they are missing.
If the alignment sleeves are missing, it will be difficult to shift, there will be clutch problems and the transmission may make noises (loose rattling).
Engage the intermediate plate on the sealing flange and push it onto the alignment sleeves -arrows-.
-- Check the release bearing for wear. Replace the clutch slave cylinder with release bearing if necessary. Refer to CLUTCH SLAVE CYLINDER WITH RELEASE BEARING, REMOVING AND INSTALLING .
Align the : 3282 with the : 3282/33 in order to install the transmission.
-- Align the arms of the Transmission Support so that they match up with the holes in the Adjustment Plate.
-- Install the Support Elements -A- as illustrated on the Adjustment Plate.
-- Install the Mounting Element -C- instead of the : 3282/29 .
-- Place the transmission on the : VAS6931 .
-- Align the Adjustment Plate so that it is parallel to the transmission.
-- Install the : 3282/29 into the rear hole for the pendulum support bolt on the transmission.
-- Secure the : VW771/40 inside the threaded hole in the transmission housing as illustrated.
-- Secure the transmission on the : 3282 with an M10 x 20 bolt -A-.
The needle bearing drift -B- must be flush with the guide on the : 3282 -arrow-.
-- Position the : VAS6931 under the vehicle. The arrow on the adjusting plate points in direction of travel.
Pay attention to the lines when installing the transmission.
-- Using the spindles on the : 3282 , position the transmission slightly upward in the area of the differential/bevel box.
-- Lift the transmission carefully.
-- Guide the bevel box and flange -C- past the driveshaft -A- and exhaust system -B-.
-- Turn the transmission into it installed position using the spindles on the : 3282 .
-- Line up the transmission and the engine and install it.
- Brake fluid can escape from the bleeder on the transmission.
-- Install the engine/transmission connecting bolt -C- (→ illustration above) and tighten. Refer to TRANSMISSION TIGHTENING SPECIFICATIONS .
-- Install the engine/transmission connecting bolts -1 and 2- tighten them. Refer to TRANSMISSION TIGHTENING SPECIFICATIONS .
-- Install all engine/transmission connecting bolts and tighten them. Refer to TRANSMISSION TIGHTENING SPECIFICATIONS .
-- After transmission is bolted to engine at bottom, remove the : 3282 from transmission.
-- Install all upper engine/transmission connecting bolts and tighten. Refer to TRANSMISSION TIGHTENING SPECIFICATIONS .
-- Attach the gearshift lever to the transmission gearshift shaft. Refer to Figure and tighten the nut. Refer to OVERVIEW - SELECTOR MECHANISM .
-- Install the selector relay lever together with the cable retainer. Refer to Figure.
Risk of damaging the threads in the transmission support by inserting bolts crooked.
- The transmission mount and bracket must be parallel to each other in order to prevent the transmission support thread does not become damaged.
-- Install transmission bracket -1- with new bolts -arrows-. Refer to OVERVIEW - SUBFRAME MOUNT .
-- Tighten the : 10-222A spindles until the transmission support -1- touches the transmission mount -2- to align the engine/transmission sub-assembly in installed position.
-- Install new bolts -arrows- and tighten. Refer to OVERVIEW - SUBFRAME MOUNT .
Install the engine/transmission mount free of tension. Refer to ENGINE, INSTALLING .
-- If present, connect ground cable -arrow-.
Risk of accident!
- Only remove : 10-222A when all subframe mount bolts are tightened to the tightening specification.
-- Connect hose/line assembly with bleeder. Refer to Fig 9.
-- After removing the : 3094 , the supply hose must be formed back into its original shape.
-- Bleed the clutch system. Refer to CLUTCH MECHANISM, BLEEDING .
-- Make sure the vacuum hose for the brake system is installed correctly. Install a vacuum hose, if necessary. Refer to OVERVIEW - BRAKE BOOSTER/BRAKE MASTER CYLINDER .
-- Mount the cable bracket on the transmission and tighten the bolts and nuts -arrows-. Refer to OVERVIEW - SELECTOR MECHANISM .
-- Install the selector cable in the cable retainer.
-- Apply a small amount of grease on the pins -arrow- for the gearshift lever -2-.
Grease allocation. Refer to the Parts Information.
-- Replace the lock washer -1- each time it is removed.
-- Adjust the gearshift mechanism. Refer to SELECTOR MECHANISM, ADJUSTING .
