Transmission housing, shift mechanism, input shaft, output shafts (pinion shafts), differential and selector rods, removing and installing: Installing
WARNING: This page is about a different car, the 2004 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.
Fig 1: Inserting Input Shaft, Output Shaft For 5Th/6Th Gears Together With Selector Rod, Shift Fork And Reverse Shaft
- Insert input shaft - 1 - , output shaft for 5th/6th gears - 2 - together with selector rod - 3 - , shift fork - 4 - and reverse shaft - 5 -.
- Insert differential - 1 -.
- As shown in illustration, take output shaft for 1st to 4th gears - 3 - with selector rods - 4 - in right hand.
- Lift differential slightly with left hand.
- At same time, second technician must slightly lift input shaft, output shaft for 5th/6th gears and reverse gear - 2 - together with reverse shaft.
- Insert output shaft for 1st to 4th gears in direction of - arrow -.
Splines of input shaft, output shafts and final drive gear/differential must engage.
- Together with second technician, displace shafts and differential in their bearing seats.
- Secure bracket 30 - 211 A for input shaft on clutch housing.
NOTE:
- For the sake of illustration, clutch housing is depicted rotated 180 °.
- Screw in bolt - A - far enough until input shaft rises slightly.
- Heat transmission housing using Hot air gun , e.g. V.A.G 1416 in area of bearing seat for grooved ball bearing/input shaft to 100 ° C for approx. 10 minutes.
- Install transmission housing.
- Install circlip - 1 - for grooved ball bearing/input shaft.
- Remove bracket 30 - 211 A for input shaft.
- If lock sleeve for selector shaft has been removed, drive it in now using drift T10168 until tool makes contact.
- Turn transmission with opening for selector shaft in assembly stand upward.
- Insert selector shaft - 1 - into lower bearing - 2 - and into shift forks - 3 -.
NOTE:
- The cap is removed in the illustration for reasons of clarity.
- Press selector shaft - 1 - against lock sleeve - 2 - in direction of - arrow - and guide downward with shift finger - 3 - through shift forks up to stop.
Shift cover - 4 - must stand parallel to bolting surface on transmission housing during this operation.
NOTE:
- If shift cover stands at an angle to bolting surface, selector shaft is not inserted in lower bearing.
- Selector shaft must be able to be moved slightly in selector motion (up- and downward).
- Tighten bolts - 3 - for cover/selector shaft - 4 -.
- Install mounting screw - 2 -. Lock elbow - arrow - must lie outside.
- Install switch for back-up lights - 1 -.
- Install flanged shaft and stub shaft with compression springs, thrust washers and tapered rings.
- Drive in seal for input shaft.
- Install slave cylinder with release bearing.
- Shift through all gears.
- Drive cap into transmission housing to stop of thrust piece T10042
Install bevel gear transfer case as follows:
Fig 11: Identifying O-Ring For Sealing Bevel Gear Transfer Case/Manual Transmission & O-Ring For Sealing Sleeve For Oil Supply
- Always replace and lightly oil O-ring for sealing bevel gear transfer case/manual transmission - arrow A - and O-ring of sealing sleeve for oil supply - arrow B - and - arrow C -.
- Slide bevel gear transfer case completely on manual transmission by joining splines of input shaft/bevel gear transfer case centrally with connecting sleeve/differential.
- Bring right axle shaft splines and differential bevel gear into alignment; rotate flanged shaft if necessary.
With proper tooth position and central guiding, the bevel gear transfer case slips up to stop against the manual transmission.
NOTE:
- Do not pull bevel gear transfer case against manual transmission with mounting bolts, otherwise bevel gear transfer case is canted and mounting eyelets can break off.
Fig 12: Identifying Bevel Gear Transfer Case/Manual Transmission Bolts, V.A.G 1669, V.A.G 1331 & VW 353
- Tighten four connecting bolts (only three depicted in illustration) for bevel gear transfer case/manual transmission - arrows -.
- Tighten conical head bolt for right flanged shaft using socket V.A.G 1669 or 6 mm socket insert, commercially available. Use a drift to prevent turning.
