INSTALLING SPINDLE/A-ARM Setup Instructions This snowmobile has been prepared at the factory to minimize required setup items; however, there are some items and inspections that must be done at a dealership or by the owner/operator. Please pay close attention to all items on the following pages. Be sure to read these instructions thoroughly before starting to set up the snowmobile.
OIL-INJECTION PUMP 3. With the rubber ski damper and damper plate SYNCHRONIZATION installed in the ski saddle, place the ski into posi- tion on the spindle axle and install the spacer NOTE: Verify the mark on the control arm is (positioning the spacer for the desired ski stance).
2. If the brake fluid level is below the low mark, remove Checking/Adjusting Deflection the reservoir cover and add Arctic Cat approved brake Drive belt length, condition, and deflection are all fluid until the fluid level is just below the high mark.
STEERING SPEED RATIO ADJUSTMENT NOTE: The lower steering post bearing housing is not symmetrical; therefore, rotating it 180° moves the steering post closer to or farther away from the drag link which changes the steering ratio. The lower speed ratio (standard position) is when the steering post is adjusted closest to the drag link.
CAUTION Do not use white gas or gasolines containing metha- nol. Only Arctic Cat approved gasoline additives should be used. 0743-091 NOTE: For optimum performance, do not exceed the 7.
