Remove outer ring/tapered-roller bearing from gearbox housing A -  Countersupport (e.g. -Kukko 22/2- B -  Interior extractor 46 through 58 mm (e.g. -Kukko 21/7-)

Press in outer ring/tapered-roller bearing in the gearbox housing –  Position adjusting washer under outside ring. –  Support the gearbox housing with a pipe section -MP 3-450 - directly below the bearing support.

Removing inner ring/tapered-roller bearing –  Before inserting the extractor position pressure plate -MP 3-431- on the differential housing.   Note Both inner rings/tapered-roller bearings of the differential housing are removed in the same way.

Pressing on inner ring/tapered-roller bearing   Note The inner ring/tapered-roller bearing for the gearbox housing and clutch housing are pressed on with the same pressure tools.

Remove outer ring/tapered-roller bearing from clutch housing A -  Countersupport (e.g. -Kukko 22/2-) B -  Interior extractor 46 through 58 mm (e.g. -Kukko 21/7-)

Press outer ring/tapered-roller bearing into the clutch housing   Note No adjusting washer is fitted at the side of the clutch housing. –  Support the gearbox housing with a pipe section -MP 3-450 - directly below the bearing support.

Remove the dust cap of the flange shaft A -  With Two-arm extractor (e. g. -Kukko 20/10-) with hook (e.g. - Matra V/170-)

Press on the dust cap of the flange shaft

Press out the differential bevel gear shaft –  Remove the circlips of the differential gear shaft. –  Position the counterholder -MP 1-223- on the front side of the shaft with centering hole -arrow- and press on shaft.

Install differential bevel gears for gearbox up to 06.00 –  Oil thrust washer compound with gearbox oil. –  Position the circlip on the side of the differential bevel gear shaft with a large diameter. –  Slide the differential bevel gear shaft with the smaller diameter (side with centering hole) into the differential gearbox housing. –  Slide the differential bevel gears onto the differential bevel gear shaft → Fig.. –  Press the differential bevel gear shaft up to its end position and secure with a second circlip. –  Insert the large differential bevel gears into position with a 180° offset and rotate into end position -arrow-.

Press on the differential bevel gear shaft

Installing large and small differential bevel gears for gearbox after 06.00 –  Insert the thrust washer compound moistened with oil. –  Insert both large differential bevel gears and secure (e.g. with flange shaft). –  Insert both small differential bevel gears with a 180° offset. –  Circlip on the side of the differential bevel gear shaft with a large diameter. –  Slide differential bevel gear shaft -arrow A- with smaller diameter (centering hole side) up to the first small differential bevel gear. –  Insert the threaded parts -arrow B- in the large differential bevel gears. Fitting position: Heel towards large differential bevel gears –  Press the differential bevel gear shaft up to its end position and secure with a second circlip.
