DESCRIPTION
T h e 2.100 t o 1 r e d u c t i o n g e a r box
operates i n c o n j u n c t i o n w i t h any o f
the following models: Model 70, 70R,
7 0 C , 70CR, 7 1 , 7 1 R , 7 1 C , 71CR, 7 2 ,
72R, 72C, and 72CR.
T h e reduction gear box consists o f a
planetary gear set which is always
engaged and reduces the input revolut i o n b y a 2.100 t o 1 ratio.
The
splined output shaft of the reduction
g e a r b o x is c o a x i a l w i t h t h e i n p u t
shaft o f the m a i n unit and w i t h the
transmission operating in forward its
direction o f rotation is the same as
that o f t h e e n g i n e rotation.
Lubricating oil is supplied b y the pump
i n the main t r a n s m i s s i o n and is
returned to the main transmission by
gravity and jet flow.
Location of several transmission
details are shown in (Figures 10 and
11). as follows:
A. Oil Filler Plug
Oil outlet Opening to Cooler
C. Oil Inlet Opening from Cooler
D. Mountings Pads and Mounting Bolt Holes
E. Shift Lever
F. Oil Drain Cap
G. Breather
H. Drive Gear
I. Valve Cover

CAUTION
NOT1:: Either item 17 or 18 on the preceding page is used depending upon
the transmission rotation. As can be seen 1;y checking the two parts in
