EAR BENCH
• Place the bench as shown in the side picture.
Fig. 5.1
Mount the pump’s feet and the lifting rings as
originally received. The oil draining-groves must
be directed toward under-part as shown in the
side picture.
• Both flanges have to be complete with related seal-rings correctly
glued. Make sure that said seals are not sized or damaged and are
properly lodged in their seats, even with the cast-iron surface as shown
in the side drawing. If not properly fixed don’t try to re-glue them: if
necessary replace the whole assembly.
Fig. 5.2
• Insert 2 plastic bushings (tool no. 8. Inner dia. 50mm – Outer dia.
84,5mm) in the front bench. Fasten the plastic bushing with screws
M8x16 (6 pcs) and washers Øe 24 (6 pcs).
• Mount the spacers (2 pcs) and the seeger rings (2 pcs) in the rear
bench.
• Upset both the benchs.
Check the integrity of the here shown bushings
and seal-rings. Remove carefully all the
incrustations on the seal-ring bushing using an
iron scratch brush.
Replace all the parts with wear-off marks. The
seal-rings must run into their seats free from
fiction and jam.

• Re-fit the seal-rings in their seats in both benchs using high-
temperature grease as lubricant around the seats. Use the related
elastic-band (tool no. 5 - Fig. 5.4) for inserting the bushing-assembly in
the flange lodgment.
• Front bench: push said assembly until it rests against the plastic
bushing on the bottom.
• Rear bench: push said assembly until it rests against the spacer
fastened by the seeger ring.
Each couple of seal-rings must be facing at 180°
as shown here under.
Mount the bushing with the 3x45° chamfer faced
to the top (upward directed)
• Insert no. 10 Viton OR 108 in the seats on the machined side of
each flange assembly in the screw’s bores. The O-rings have to be
lightly pushed in to grant their lodgment also by vertical positioning of
the flange. Should be necessary: use a rubber hammer and pushing-
pad to insert the O-rings.
