4.4.3 Assembling input shaft seal
Apply thin coat of Loctite 574 on periphery of new radial
shaft sealrings (item 1, Fig. 4-3a and items 1-2, Fig. 4-
3b) and grease lips with KLUEBER STABURAGS NBU
30.
For transmission ZF 63 IV ratio I=1.56 only use grease
Fa KLUEBER AMBLIGON TA 15/2.
Put a new shaft sealonto the mounting mandrel.
Drive shaft sealuniformly into the housing by tapping
slightly onto the mounting mandrel.
NOTE
The sealing lip (A) on the shaft seal should point into
the inside of the housing. The radial shaft seal must
be adjusted so that the sealing lip does not run on
the former running point of the shaft.
Only for transmission size i = 2.0and i = 2.5.
The radial shaft seal ring (item 1, Fig. 4-3b) of the in-
put half of the housing can only be mounted after
the housing halves have been mounted with the
gear set.
ALTERNATIVELY (Fig. 4-3c)
For models ZF 63 IV - ZF 80IV - ZF 80-1 IV
.
Smear Loctite 574 on the outside diameter of the
input shaft seal using a roller.
.
Lubricate the inside lip with Kluber Staburags
NBU30 grease.
.
Insert the input shaft seal(item 2) into input shaft
using the appropriate bushing p/n 20.0012.01 (item 1).
.
Use mandrelp/n 20.0012.02 (item 3) to position the
input shaft sealin the correct way.
For models ZF 85 IV - ZF 80IV (ZF 85 IV DERIVATE
VERSION)
.
Smear Loctite 574 on the outside diameter of the
input shaft seal using a roller.
.
Lubricate the inside lip with Kluber Staburags
NBU30 grease.
.
Insert the input shaft seal(item 2) into input shaft using
the appropriate mandrelp/n 20.1072.01 (item 1).
.
Position the input shaft sealin the correct way.
4.4.4 Mounting the breather filter
NOTA
Due to the taper thread, the breather (item 1, Fig. 4-
4) do need not to be coated with Loctite 243.
Apply thin coat of Loctite 574 to the breather (item
1, Fig. 4-4).
Tighten
carefully
during assembly (hand-tight).
Check leakage during a later test run. Retighten slightly
if it leaks.
