SERVICING THE BRAKE PEDAL SHAFT BUSH - the ends of the two pins ride in the peak of the INGS : crease : See Figure 19.19 . â¢ If there is insufficient travel in the linkage to fully apply the brakes , a simple visual inspection should identify the cause . 20.1 . Confirm that the brake pedal is firmly attached to the pedal shaft . See Figure 20.1 . Brake Pedal Figure 19.19 â¢ The brake arm pivots on a square - headed stud . â¢ The two pins are forced against the backing plate when force is applied to the arm .

Series 1000 and 1500 21.2 . Remove the battery hold down , battery and bat - tery tray from the unit . See Figure 21.2 . NOTE : Lubrication with grease may accelerate bushing wear . If lubrication is applied it should be in dry form such as graphite or PTFE ( Teflon ) . 20.8 . Secure the inner bushing with a new cotter pin Battery hold down and the flat washer that was previously removed . 20.9 . Move the pedal through itâs range of travel to check for binding . If binding is encountered : â¢ Bind in just a portion of the travel may be caused by a bent pedal shaft . â¢ Constant bind is likely to be caused by a bent bracket . â¢ Also check for interference between the parking brake and cruise control interlocks .

TRANSAXLE REPLACEMENT : CVT â¢ The single speed transaxles used in our CVT riders has evolved over the years . Internals have changed . Some have had the Variable Speed Pulley integrated into the transaxle . If you are replacing a transaxle it is very important to care - fully match the transmission part numbers between the old and new . A part number on the transmission case might be the number of the case half . Visually compare the IPL drawing with Figure 21.3 the actual transaxle to assure a match . â¢ Before condemning a transaxle , check to make sure the brake is not locking up the transaxle . â¢ Check the drive belts for damage or wear and make sure they are the correct belts and are not the cause of drive problems . â¢ When replacing a transaxle within the warranty period , we have a like - kind exchange program . â¢ Out of warranty transaxles can be serviced . 21.1 . Disconnect the battery cables ( negative first and then positive ) . 34
