IFS Installation Instructions: Notes: ***Measurements in these instructions are based on a 15 Diameter Tire (Size 11L-15SI @ 35PSI) and frame width of 22 across the top, if you have different tires diameters and frame width please contact Wipe Out Enterprises Inc. for additional information.*** 1) Tractor must be placed on level surface 2) Set rear tire pressure as if you were setting tractor up to go a pulling event. 3) Remove Fuel/Water Tanks, Wiring, plumbing and etc. from front end of frame. 4) You will need to support front end of frame at desired ride height and place on jack-stands. (See Picture B ) Picture B 5) Center-Line of front axle needs to be determined, if unsure take straight-edge and mark both sides of front axle and centerline will be located half-way between marks. 6) From axle centerline make a mark on the Frame 6 Forward and 6 to the rear. These marks represent the center of the tubes on the A -Arm frame mount structure. You need to measure from the floor to the bottom of the frame at the rear mark, and then you need to subtract 11-5/8 to determine the distance from the frame to lower A -Arm pivot point. From floor to center of lower A -Arm mount should be 11-5/8 (See Picture C ) 4 P a g e
Picture C 7) Cut A -Arm frame mount structure to determined length from lower A -Arm pivot to top of tubing. a. Cut lower A -Arm frame to achieve the 4 Max distance at ride height. 8) Tack weld A -Arm frame mount structures to bottom of frame, maintaining the width between the lower A -Arm pivots at approx. 24-1/2 to 25-1/2 (See Picture D ) ***This might change depending on your frame width, measurement is for a 22 Wide Frame*** a. A -Arm frame mount structures need to be parallel to one of another and perpendicular to floor. Picture D 5 P a g e
9) Build X Bracing between A -Arm frame mount structure and tack weld into place, bracing should start in-line with bottom A -Arm Pivot and run to opposite side as high as you can without interfering with any other components. (See Picture E and X Frame highlighted in Picture) Bracing is required on front and rear A -Arm Frame Mount Structures. Picture E 10) Side bracing is required, needs to start at bottom front and extend towards rear of frame. (See Picture F ) 6 P a g e
Picture F 11) Upper Shock Mount needs to be located on outer frame rail approx. 15 above lower A - Arm Pivot bracket. Upper mounts need to be located straight above lower A Arm Shock brackets and tack weld in place. (See Picture G ) Picture G 7 P a g e
12) Locate Steering Cylinder, center of steering cylinder body ( X ) should be centered between Y and Z lines. Center of Steering Cylinder Ram ( A ) should be centered between B and C lines. (See Picture H ) Picture H 13) Install Upper and Lower A Arms (Parts A7 & A9) along with coil-over, spindle steering knuckle assembly and spindle pivot. After installed move components to verify that there is no binding between the components. Also verify that the ski s hit the ground before the shocks bottom out. 14) If you are satisfied with the test fit from step #12 then finish welding all the components complete. If not make adjustments as needed and then finish welding the components. 15) Once finish welding is completed, we recommend that components be painted before final assembly. 16) Assemble components as in step #12 and also install springs on shocks. 17) Put Front tires back on tractor and remove jack stands 18) Place weights on tractor, as if you were setting tractor up for a pulling event. 19) To achieve desired ride height, the nut located under the spring will need to be adjusted. To make adjustments, tractors front wheels will need to be jacked up off the ground. 20) The Standard kit comes with 500 pound springs, if overall compressed spring length is less than 5-5/8 then springs will need to be upgraded to either 600 or 650 pound springs. 21) Once springs have been verified, the A -Arms will need to be adjusted so the front wheels are straight vertically. When you check this the tractor needs to be sitting on the ground with the weights in place as you were going to a pulling event. 8 P a g e
22) Steering cylinder needs to be adjusted so the same amount or ram is showing outside of the steering cylinder body, then adjust Heiman bearings so the center to center distance is the same as the A Arm Pivots. (See Picture I ) Picture I 23) With steering cylinder still centered, place a string past the rear tire to create a straight line running past front tire. Take a measurement from string to edge of from rim, make adjustments to outer Heiman bearings on outer tie-rod to achieve parallelism with rear tire. (See Picture J & K ) Picture J 9 P a g e
Picture K 24) Front rims need to be parallel to each other in the horizontal plane, to complete this task a straight edge will need to be placed on outside of both front tires horizontally and a measurement taken in front of tire and rear of tire. Measurements need to be with ¼ of each-other, make adjustment to outer tie-rod end located on opposite side of tractor from step #22. (See Picture L ) a. Front tires being towed-in is preferred over being towed-out Picture L 10 P a g e
25) Make sure all fasteners are tightened. 26) If Coil-Over Shock needs either Compression or Rebound adjustment, See Picture M Picture M C:\desktop\qualitycontrol\instructions\WOEI-0009-IFS Installation.docx 11 P a g e
