LUBRICATION<br />
The engine is lubricated by oil<br />
mixed with the fuel. Correct fuel-oil<br />
ratio is 20:1. Only regular gasoline and<br />
a branded Air Cooled Two Cycle Engine<br />
Oil is recommended.<br />
Some models use a guarded, open<br />
drive chain which is automatically lubricated<br />
by a tube leading from<br />
crankcase bleed valve. Chain should<br />
be spray lubricated after storage and<br />
inspected regularly to see that end of<br />
tube is directly above center groove<br />
Fig. 2—Schetnotic view of steering armt,<br />
tie rodf and drag iink (early modeis) showing<br />
proper method of oHachment. Loter<br />
modeis use two identicol tie rods and ski<br />
iink (steering arm) has oniy one attaching<br />
hole; refer to Fig. 3.<br />
Fig, 3—Schematic view of steering arms<br />
and associated parts us«d on late models.<br />
of lower chain sprocket and that tube<br />
is open and clean.<br />
On models with enclosed chain case,<br />
fluid level should be maintained at<br />
lower housing plug opening using<br />
SAE 50 engine oil. SAE 90 Multipurpose<br />
G^ar Oil may be substituted if<br />
SAE 50 oil is not available.<br />
Ski legs (spindles) are equipped<br />
with pressure gun fittings and should<br />
be lubricated after each 25 hours with<br />
low temperature grease.<br />
Drive train and track are equipped<br />
with self aligning sealed bearings<br />
which do not require lubrication.<br />

modeis with open chain, ioosMi the two<br />
bolts (A) and tum adfusting bolt (B)<br />
ttnsion is correct.<br />
ADJUSTMENT<br />
STEERING SKIS. Steering skis<br />
should be parallel with each other and<br />
with vehicle frame when handle bar<br />
is in a normal straight driving position.<br />
Tie rod or drag link can be adjusted<br />
after disconnecting either end<br />
and steering arms are interchangeable<br />
from left to right side. On <strong>1969</strong><br />
models, refer to Fig. 2. Connect tie<br />
rod to inner hole of both steering<br />
arms, and drag link to outer hole of<br />
right steering arm as shown.<br />
On later models, two interchangeable<br />
tie rods are used as shown in<br />
Fig. 3. With handle bar properly positioned,<br />
disconnect either tie rod as<br />
required and adjust to correct length<br />
making sure threads are equalized on<br />
both ends of rod.<br />
DRIVE CHAIN. Drive chain should<br />
have V4'% inch deflection measured<br />
from a straight edge midway between<br />
upper and lower sprockets. To adjust<br />
the open drive chain on models so<br />
equipped, loosen the two bolts (A—<br />
Fig. 4) and turn adjusting screw (B)<br />
until tension is correct. Hetighten bolts<br />
(A) after completing the adjustment.<br />
On models with enclosed drive<br />
chain, remove large plug (A—Fig. 5)<br />
to check tension and adjust by loosen-<br />

Push cap screw down in slot to<br />
tighten chain, or up to loosen. If cap<br />
screw bottoms in slot before slack is<br />
removed, install bolt in alternate<br />
threaded hole which has appeared at<br />
top of slot. Tighten cap screw securely<br />
and reinstall plastic plug when<br />
tension is correct.<br />
BRAKE. Friction disc for the caliper<br />
type disc brake is combined with<br />
the main drive (upper) sprocket<br />
on early models (see Fig. 6). Late<br />
models use fixed face of driven sheave<br />
as friction surface as shown at (C—<br />
Fig. 5).<br />
Brake should not drag when released<br />
but should fully engage before hand<br />
lever touches handlebar grip. To adjust<br />
for wear, remove cotter pin (Fig.<br />
6) and turn castellated nut until there<br />
is a slight drag on brake disc, back off<br />

Hand lever travel is adjusted at the<br />
two anchor nuts.<br />
TRACK. To adjust track tension,<br />
raise rear of machine until track is<br />
clear of ground, then measure distance<br />
between running board and lowest<br />
point of swing arm as shown at<br />
(D—^Fig. 7). Measurement should be<br />
3-3% inches for <strong>1969</strong> models; four<br />
inches for 1970 models and as follows<br />
for 1971 machines:<br />
Models 295 & 340<br />
4% in.<br />
Model 292<br />
4H in.<br />
To adjust the track, loosen the two<br />
clamp bolts (1) and turn adjusting<br />
bolt (2) until measurement is correct.<br />
NOTE: Whenever track tension has<br />
been adjusted, alignment MUST be<br />
checked as outlined in TRACK SERV-<br />

OVERHAUL<br />
SKIS. Steering skis, spindles and associated<br />
parts are interchangeable<br />
from right to left. Skis have renewable<br />
wear runners. Ski springs are<br />
equipped with a conical rubber<br />
bumper which should be installed to<br />
rear.<br />
IMPORTANT: DO NOT tighten<br />
locknut on bumper stud tight against<br />
spring leaf, or action of the spring will<br />
be restricted.<br />
TORQUE CONVERTER. Refer to<br />
Fig. 9 for an exploded view of torque<br />
converter drive sheave and to Fig.<br />
10 for driven sheave. Torque spring<br />
(13—Fig. 10) should be preloaded<br />
4 turn (one cam) when unit is<br />
assembled.
