Read the instructions carefully. The items refer to the parts list and service kits section.
6.5 Reassembly
General Notes
All parts must be cleaned thoroughly before reassembling.
Any deposits remaining on the parts can cause difficult
disassembly the next time the Alfa Laval Gamajet needs servicing. Also, it may cause misalignment of parts and the potential
for premature failure.
Unless otherwise stated, apply a dab of a
Teflon-based anti-seize compound
to
all threads when reassembling; this will
prevent galling of threads and ease any future disassembly.
To ease installation of all O-rings, they should be lubricated prior to reassembly. Lithium-based soap grease is acceptable, for
Viton
O-rings; however, a Silicon based lubricant must be used for EPDM O-rings.

Gear Train
Turn to drawing 5: Insert the Planetary Gearbox Screws (31) through the Planetary Gearhead (12).
Push the Input Shaft (drawing 3) through the Input Shaft Lower Bearing Housing (drawing 2).
While installing the (drawing 2) onto the (12), ensure the Input Pinion (56) meshes properly with the top layer of gears.
Using a #1 Phillips, screw the (31) into the (drawing 2).
Turn to drawing 6: Install the Gearhead (drawing 5) back into the Gearbox (1).
After aligning the screw holes, thread the Gearhead Short Screws (47) back into the (drawing 5) using a #2 Phillips
screwdriver. Make hand tight.
Turn to drawing 8: Install the Gearbox Static Seals (39) into the Gearbox (drawing 6). The internal spring of the (39) should be
face out and be visible.
Install the Input Shaft Upper and Lower Bearing Housing (drawing 1) and (drawing 7) into the proper ends of the Gearbox
(drawing 6) by using equal pressure around parts. They will snap into place.
Turn to drawing 10: Place the Rotor (35; drawing 9) over the end of the Input Shaft (36).
Install the Input Shaft Lockwasher (58) and Nut (59)
using an 11/32” socket. Hold the (35) stationary with a pair of pliers while
tightening the (59).
Place the Output Shaft (11) into the output side of the Geartrain (drawing 10). Ensure the slot of the (11) is aligned with the
flats on the Gearhead
’s shaft.
Drawing 15
Body Assembly
Slide the Tee Housing Bevel Gear (14; drawing 14) over the end of the Stem (3; drawing 11). Align the hole in the (14) with
the Dowel Pin (50).
Place the first Tee Housing Bearing (20) and Seal (24) (spring side up) onto the (3).
Push the Tee Housing (4; drawing 12) over it until it is flush and fully seated.
Install the second (24), spring side down, over the (3).
Tip
: Now, Place the second Tee Housing Bearing (20) into the Stem Base (19; drawing 13), aligning its hole with the Bearing
Locating Pin (34). Now, invert the (4)/(3) assembly and place it over the (20)/(19) assembly. This technique ensures correct
alignment of (20) and (34). Apply pressure to the (19) to drive the (20) and (24) into the (4).
Align the through holes of the (19) with the threaded holes in the top of the (3)
. Using a 5/32” Hex Key, thread Stem Screws
(26) and Stem Screw Lockwashers (46) into the (3). Tighten in a star pattern.
Thread the Tee Housing Cap (13) to the end of the (4).
Note
: This is a
Left-Handed
thread.
Drawing 16
Geartrain Installation
Insert the Geartrain (drawing 10) from into the Body Assembly (drawing 15). Rotate the Tee Housing (4) until the Output Shaft
(11) falls into the slot of the Tee Housing Cap (13).
Thread the Cap (2) into the Body Assembly (drawing 15). Be sure to use the flats provided on the (2). Tighten.
Warning: Hold or turn on Stem (3). DO NOT hold or turn on Tee Housing (4) or Tee Housing Cap (13). Doing so will
damage the Geartrain (drawing 10).
