Job:
Removing the Flange (see also page 3)
Normal Procedure
Remove flywheel (Job Card 04.09.01). Screw stud (4)
into crankshaft jounal. Fit crossbearer (2) and screw
nut (3) in place on stud (4). Unscrew plug (11) from
connection in flange (12) and screw adapter (6) in
place. Fill pump (1) with oil (Job Card 04.16.02),
screw into adapter so that pump will not foul
crossbearer (2). Tighten bolts between flange (12)
and adapter (6) plus bolts between adapter and
pump (1) so that the hydraulic oil used for flange
spreading will stay in.
After releasing valve screw (10) somewhat, operate
pump a few times until oil comes out through valve
screw (10) free from bubbles. Tighten screw (10).
Operate pump up to 2000 bar or so, whereupon
flange (12) will normally easily come off the cranks-
haft journal.
The flange must not "shoot off" the crankcase, but
come off in stages. To this end make sure that the
distance between bearer (2) and retaining nut (3) will
not exceed 5 mm in each stage.
Exceptional Procedure
To assist in the hydraulic action, additionally turn about crossbearer (2) and use puller bolts (7). To secute
bearer and flange, screw nut (3) up to bearer.
Whenn pulling off flange (12), be sure not to put your hands between flange and crossbearer.
This job should preferably be entrusted to
Deutz servicemen.
Tools:
- Standard tools
- Hydraulic flange spreader assy. (Sec-
tion 1.8.1).
