Rear Brake Lever; Recommended Transmission Lubricant - Arctic Cat Alterra 90 Preinstallation Manual

 NOTE: Inspect the area around the drain plug for
leaks.
2. On the transmission, check the lubricant level using
the level plug. If the lubricant is not visible at the
level hole, add recommended lubricant until the level
is visible at the bottom of level hole. Do not over-fill.
Recommended Transmission
Lubricant
The recommended transmission lubricant to use is SAE
80W-90 hypoid.
Checking Front Wheel Brake
System
The front wheel brake system will need to be adjusted
before delivery. To adjust the system, use the following
procedure:
1. Raise ATV enough to allow the wheels to spin freely.
2. On the brake lever/cable assembly (A), loosen both
jam nuts (B). Turn both cable adjusters (C) counter-
clockwise until both front wheels do not spin freely.
3. Turn both cable adjusters in 1/4 turn increments
(clockwise) until wheels spin with a very slight
amount of drag.
4. Lower ATV, push ATV forward, and compress brake
lever.
5. If front wheels lock, adjustment is correct.
6. If front wheels do not lock, additional adjustment is
necessary.
Checking Hydraulic Brake System
The hydraulic brake system has been filled and bled at the
factory.

Rear Brake Lever

1. With the hydraulic brake reservoir in a level position,
check the fluid level. It must be visible in the sight
glass.

2. Compress the brake lever several times to check for a
firm lever. If the lever is not firm, the brake system
must be bled.
3. To bleed the brake system, use the following procedure:
A. Remove the cover and fill the reservoir with DOT
4 brake fluid.
B. Install and secure the cover; then slowly com-
press the brake lever several times.
C. Install one end of a clear hose onto the bleed
screw and direct the other end into a container;
then while holding slight pressure on the brake
lever, open the bleed screw and watch for air bub-
bles. Close the bleed screw before releasing the
brake lever. Repeat this procedure until no air
bubbles are present.
 NOTE: During the bleeding procedure, watch the
KC555A
reservoir very closely to make sure there is always a
sufficient amount of brake fluid. If the fluid level gets
low in the reservoir, refill the reservoir before the
bleeding procedure is continued.
D. Repeat step C until the brake lever is firm.
4. Carefully check the entire hydraulic brake system
that all hose connections are tight, the bleed screw is
tight, and no leakage is present.
