ALIGNING MAINSHAFT TO CRANKSHAFT
As viewed looking down from rear of machine, spot
screws (A. Fig. 17) in the couplings must align with
the spots in the looper drive crank (B) and set screws
(C) must align with the flats on crankshaft (D) and
mainshaft (E).
Mainshaft must be positioned laterally with .045 inch
(1.14mm) clearance between the right side of its
head and the bed .045" (1.14mm) casting as shown
in Fig. 18.
Looper drive crank (B, Fig. 17) must be positioned
laterally with 1/32 inch (.8mm) clearance between it
and mainshaft (E) as shown in Fig. 17. Once these
settings are made, it is very important that the
coplings are tightened in the following sequence for
best performance.
Tighten spot screws (A) temporarily, to the looper
drive crank. Tighten set screws (C) temporarily, to the
crankshaft and mainshaft. Torque screws (F) to 19 -
21 in. lbs. (22 - 24 cm/kg). Loosen spot screws (A)
and set screws (C). Re-torque screws (F) to 19 - 21 in.
lbs. (22 - 24 cm/kg), then torque screws (A and C) to
19 - 21 in. lbs. (22 - 24cm/kg).
The oil drip plate (A, Fig.19) located in the oil reser-
voir should be positioned with its tip in the recessed
cut out in the bed casting, as far to the left as pos-
sible without touching. It has elongated mounting
holes and can be adjusted by loosening (2) screws
(B) in top of the oil reservoir back cover to position as
required, retighten screws.
