on the brake shaft. Late #SO10 transmissions and replacement transmissions of both models were pro-
'
duced with needle bearings. To insure receiving the correct side covers, please order as follows:

BRAKE SHAFTS
A.
Original equipment brake shafts used in ball bearing type transmissions cannot be used with needle
bearing
side
covers.
B.
Presently stocked brake shafts and those used in needle bearing transmissions are interchangeable.
To
install in ball bearing transmissions, use four 1197 Shim Washers between the brake shaft gear
and the left side cover plate.
SPLINE
SHAFT AND MATCHING GEARS
All tractors and replacement transmissions produced previous to tractor Serial No. 11628, contain Part
NO. 3521 Spline Shafts with 10 straight
sides
splines and matching gears, Part
Nos.
3523, 3524 and
3526.
All tractors and replacement transmissions produced after tractor serial number 11628, contain Part No.
3521 Spline Shafts with 11 involute tooth form splines and matching gears, Part Nos. 3523, 3524 and
3526. The matching gears for
the
two types of Spline Shafts are NOT inter-changeable, although the
part numbers are identical.
It
is
suggested that, when ordering the #3523 High and Second Gear, the #3524 Low and Reverse Gear
or the #3526 Splined Pinion Gear, the number of Splines on
the
#3521 Spline Shaft be noted.
This
will
eliminate the possibility of receiving gears which will not assemble on the Spline Shaft.
The ordering of the #3521 Spline Shafts should be handled in the same manner.
#3559
BRAKE SHAFT
The original #3559 brake shaft has been replaced with a new design. The new shaft has more strength and able
to carry more load.
The #3502 differential case and gear has been replaced with part #7243 and #3559 (See Figure A). If
either
the
original #3559 or #3502 are required, order
both
new parts #3559 and #7243. The new parts are shown in Figure
A. The original construction
is
shown in the exploded view drawing.
