BODY, STEERING AND SUSPENSION Frame Straightening and Reinforcement Because the frame is hidden beneath all of the fenders, fuel tank covers, seat, etc very little attention is usually paid to itMost owners and technicians never think about it because it requires so little maintenanceHowever, the frame is the base of the ATV, and if it ever needs any attention, knowing something about it and how it relates to the rest of the machine can be very helpfulThe purpose of the frame is 1) to hold all of the parts in correct relationship with each other so proper steering and handling can result, and 2) to deliver power to the ground in straight, smooth mannerIf damaged ATV enters the shop, inspect the frame carefully for cracks or bends in the tubing and welded areasNOTE: This procedure is for returning slightly bent frame to its original strengthSevere bending will require frame replacementIfthe machine will be subjected to extremely heavy use this reinforcement should be installed priorto vehicle deliveryBrace Kit PN 2870730 will fit model numbers W857527, W867527, W867627, W877527, W877828 and W8875271Remove the fuel tank2Drain the carburetor3Remove the battery4Invert the vehicle as shown5Remove the front wheels6Remove the strut spring on the side the jack will be positioned
