Do this to both Right & Left Track Expanders. On ends of each Cap Screw, loosely apply
two (2) 3/8 Nuts with 3/8 Lock Washer between. Insert 3/8-16 x 3" Cap Screw into a
3/8 WI Washer and then through the two holes in rear of each Expander (you may have to
rotate Rear Axle so Cap Screw will pass through) and secure with 3/8 WI Washer and
3/8-16 Locknut. NOTE: Do not over-tighten this Cap Screw and crush the Expander.
4. Take 3/8-16 x 1 Cap Screw and insert into one"looped" end of #41 Spring. Insert
this Cap Screw Assembly into the 3/8" hole in lower outside rear of #1B Plate (right
"inside" of Body) and secure inside with 3/8-16 Locknut (see drawing for correct
positioning). NOTE: Insert Cap Screw so that Spring's "looped" end can lay "flat"
against #1B Plate. In a similar manner, attach the other "looped" end of #41 Spring to
the top inside of #11 Bar and secure with 3/8-16 Locknut. NOTE: In both cases, leave
The Cap Screws sufficiently loose to allow the Spring moderate swiveling action.
5. Attach #19 Drawbar under #1G Rear Pan with two 3/8-16 x 3/4 Cap Screws and secure
inside #1G Pan with 3/8 WI Washers and 3/8-16 Locknuts.
6. Take Gas Tank and Mounting Bracket Assembly and mount onto #5 Tank Mount - note
how the four holes and slots line-up with each other. Insert each of four 5/16-18 x 3/4
Cap Screws into 5/16 WI Washers and then into the (above) aligned slots and holes.
Secure each Cap Screw on other side with 5/16 WI Washer and 5/16-18 Locknut.
7. Mount the (above) Gas Tank Assembly to the top rear of Tractor Body aligning the
two 5/16" holes in #1D Brace and two 5/16" holes in the #1G Pan with the four remaining
slots in #5 Tank Mount. Insert each of four 5/16-18 x 3/4 Cap Screws into 5/16 WI
Washer and from outside, insert into the four slots of #5 Mount. Secure these Screws
inside Body with 5/16 WI Washers and 5/16-18 Locknuts.
8. Mount #10 Bearings (with 10R on right side and 10L on left side and with 10C Pull
pointing up) between #lB Plate and their respective #1AL or 1AR Left or Right inside
body wall, being sure #10C Pull protrudes up through 1/2" hole in top rear of #1AR and
1AL Wall. Loosely secure 3/8 WI Washer and 3/8-16 Locknut to protruding #10C Pull.
NOTE: Holes in #10 Bearing must line up with slots in its respective #1B Plate and #1AL
or 1AR Wall. Using 5/16 WI Washers over 5/16-18 x 3/4 Cap Screws, insert into slots of
#1B Plate and #1AL or 1AR Wall. Loosely secure inside with 5/16 WI Washers and 5/16-18
Locknuts.
NOTE: Check that above Cap Screws on #1B Plate and #1AL or 1AR Wall point toward each
other on each side and that Locknuts are against #10 Bearings in each case.
9. Slide three 7/8 WI Washers onto the end of each #20 Sprocket and Shaft. From out-
side the Body, insert each shaft into the Oilite Bushings in #10 Bearings. Take a
straightedge and align the faces of the 54 tooth Sprocket on the #22 Drive Wheel with
the 8 tooth Sprocket on the #20 Sprocket & Shaft. This alignment can be accomplished by
adding more or removing 7/8 WI Washers from the #20 Shaft.
10. On each side of Tractor body, wrap a length of #38 Roller Chain around 8 tooth
Sprocket, on #20 Shaft and around 54 tooth Sprocket of #22 Drive Wheel - secure with
Connector Link. Draw up on each #10 Bearing Assembly and secure by now tightening the
six (5) 5/16-18 Locknuts on each #10 Bearing.
NOTE: Tighten 3/8-16 Lock Nut on #10C Pull just enough to hold #10 Bearing in place,
but do not over-tighten and draw #10 Bearing up any further as it will cause #38 Chain
to be over-tightened and result in premature wear of chain. (The #10C Pull is just
used to keep the #10 Bearing in place when Dozer is working under extreme loads.)
