Assembly Instructions - SS57 Sno-Skat

Unpacking the Kit:

Care must be exercised in unpacking the Kit to avoid bending or scratching the

various components. As the parts are unpacked lay them out neatly and check theparts against the enclosed Parts List. Notify us immediately of any shortages.

Setting up for Assembly:

It is best to set the Body in an upright position on the edges of two saw-horses

or on top of a crate. This will allow you to easily work around and underneath the

Sno-Skat. NOTE: The directions 'Left & Right' and 'Upper & Lower1

referred to

in the following instructions are determined by standing behind the Sno-Skat and

looking forward. 'Inside' refers to the side of a part which is closest to an imagi-nary center line running down the length of the Sno-Skat. 'Outside' refers to the

side farthest from the above defined center line.

Lubrication:

All Bearings are lifetime lubricated and sealed. Follow manufacturer's re-

commendation on Engine and periodically oil #24 Drive Chain with light oil.

ASSEMBLY:

1. Insert threaded ends of #3 Pulls into 1/2" holes on inside of # 1H Brackets.

Slide 3/8 WI Washer over each protruding threaded end of #3 Pulls and loosely turn

on two 3/8 Nuts. (Note: #3 Pull must lie flat against inside of #1H Bracket)

2. From the right side insert the #15 Pivot Rod through the 5/8 slot in#lH Bracket

and then into the 5/8 hole in #3 Pull. In proper order slide onto #15 Rod, #14, 12

and 13 Tubes spacing them with #26 Track Idlers. Insert end of Rod into left #3Pull and #1H Bracket. Shim out ends of #15 Rod with 5/8 WI Washers on each side

of Body and secure with 5/8 Snap Ring.

Secure each Bearing with 1/4 WI Washer, Lock Washer, and Nut. Secure the two

set screws in #27 Bearings with Allen Wrench provided.

6. Insert each #7 Leg Assembly in their respective #1I Tubes. (Note: on each

side the #7B Stop must point forward - note drawing showing proper location of

#7 "left" Leg). Slide #8 Arm over end of respective #7 Leg and secure by driving

in 5/16 x 2 Spring Pin. (Note: any play can be taken up with 7/8 WI Washer be-

tween top of #11 Tube and #8 Arm).

7. Insert #4 Tiller Assembly into the center #1I Tube of #1 Body Assembly.

(Note: use 7/8 WI Washers between top of #1I Tube and #4C Plate to raise #4C

Plate so it is level with the #8 Arms on each side). Below use 7/8 WI Washers to

shim out lower end of #4A Tiller and secure with 1-1/2 x 1/8 Cotter Pin.

8. Following the Drawing, insert Pin ends of #9 Links into respective 3/8 holes of

#8 Arms and mating 3/8 holes in #4C Plate. Secure both left and right Links below

using 3/8 WI Washers and 1 x 1/8 Cotter Pins.

9. Slide #10A Bracket of #10 Ski Assembly onto the end of its respective #7 Leg.

Shim with 7/8 WI Washers and secure with 2-1/2 x 1/8 Hitch Pin. (Note: at this

time check steering mechanism by moving #4 Tiller back and forth to see that

everything moves freely without binding and that all parts are secure - #4C Plate

should move approximately 23 off center both left and right before hitting #1F

Stop).

10. Mount #11 Bracket against Engine Case using 5/16-24 x 1/2 Cap Screws and

5/16 Star Washers over each Screw end. Slide #16 Clutch Assembly on Engine

Shaft and shim out (between Engine Case and Clutch) with 3/4 WI Washers until

Clutch rotates freely and clears the above 5/16-24 x 1/2 Cap Screw heads by

approximately 1/16". Remove Clutch from Engine Shaft. Remove Snap Ring re-

tainer from Clutch Shaft and remove the Sprocket and Clutch Drum Assembly from

the Clutch Body. (Note: do not tamper with Clutch Shoes) Insert 3/16 square Keyon Engine Shaft and slide the remaining Clutch Body Assembly (less Sprocket and

Drum Assembly) onto Shaft and up tight against the previously determined 3/4 WI

Washers above. Using the Allen Wrench provided tighten both set screws on

13. Take the end of the Control Cable from the #20 Control (mounted on the left

side of the #4B Tiller Handle) and insert it into the hollow #19 Bushing. Slide the

#23 Brake Return Spring over the Cable and insert the end of Cable into the single

1/4" hole in end of top "loop" of #17 Brake Band. From the side slide the #18

Connector into the above "loop" and engage the Control Cable in the Connectors'

slot. With a Phillips screwdriver tighten this Connector so it is squeezing down

on the Control Cable. (Note: at this point check the left #20 Control so that

squeezing the Control will apply sufficient pressure on the Brake Band so as to

completely stop the #16 Clutch from rotating - you may want to cut off some of the

end of the Cable as only about 1/8" can be protruding out the other side of the #18

Connector inside the upper "loop" of the #17 Band). NOTE: The #19 Bushing can

be screwed in or out to make finer Brake adjustments.

14. In a similar fashion insert the remaing #20 Control Cable into the #19 Bushing

mounted on the Engine and pass it through the slotted arm below. From below

mount the #18 Connector, locating it such that when you squeeze the #20 Control on

the right side of #4B Handle you open the throttle on the carburator. (Note: to

achieve the safest operation you must set this adjustment so that when the #20

Right Control is released the throttle will return to the idle position by itself).

Again, this finer setting can be accomplished by screwing the #19 Bushing in or

out.

15. Loop the #24 Drive Chain over the 42 tooth Sprocket on the #6 Drive Shaft

Assembly and connect the Chain ends with connector link provided. By tilting the

Engine slightly, drop the Engine into the Engine Compartment of #1A Body Assem-

bly. (Check that #20 Brake Control Cable is not being pinched against the edge of

Engine Compartment - it should make a large loop as it comes out of the Engine

Compartment). Slide Engine rearward and loop other end of #24 Chain over the

Sprocket on the Clutch. Slide Engine forward and align Engine mounting holes

with slots in the #1B Mount. Slip a 5/16 WI Washer over end of each 5/16-18 x 1Cap Screws and from inside the Engine Compartment insert into Engine mounting

holes and pass through slots in # IB Mount. Below slip a 1" square plate over

each protruding Cap Screw followed bya 5/16 WI Washer Lock Washer and Nut

18. Assemble Track Segments using steel pins provided. (Note: put light oil on

pins before inserting to make them slide - check that pins are pressed completely

into Track and recessed each side). Before inserting last pin, thread Track over

#26 Track Idlers, around Sprockets on #16 Drive Shaft Assembly and under #5

Boggie Assembly. Join the two ends of Track with final pin. (Note: check that

arrows (molded into Track) point in the direction of forward travel and that the

smooth side of the Track is to the inside.

19. In the rear draw up evenly on the threaded ends of the #3 Pulls until the slack

is out of the Track (without stretching it). Check that the Track moves freely by

hand - loosen if necessary - and then tighten the second 3/8 Nut against the first

to hold position.

20. Mount the #2 Hood Assembly over the Engine and line up the three 5/16 holes

on each side with their respective mating holes in the #1D Braces. Using a 5/16

WI Washer on each 5/16-18 x 3/4 Cap Screw insert (from outside) into holes and

secure inside with 5/16 WI Washer, Lock Washer and Nut.

21. Take the roll of plastic Trim Edging and on the lower front corner of the #2

Hood start sliding the Edging on, working your way neatly around the two corners

and down to the bottom of the other side - at this point cut off remaining Edging

cleanly with a "tin snips". Repeat this procedure again on the inside edge making

sure you have pushed the Edging on as far as it will go.

22. At this point you have completed Assembly of your "Sno-Skat". It is now

important that you take time to go completely over the machine again following

the above assembly instructions and check your work. Constantly look for tight-

ness of bolts and proper location and fit of various components. Especially im-

portant are the two Control Cables - they must be adjusted and secure so they

tighten and release their respective Brake Band and Throttle. Also that the

Cables are not cut or pinched and that they are free to move.

OPERATION:

Again, before starting the Engine check that the Track, Clutch and Drive Chain

rotate freely. Straddling the machine, standing onthe running boards, squeeze
