Instruction Sheet IS-13009B #660699 DRAG LINK INSTALLATION & ADJUSTMENT For X Series and H Series vehicles equipped with an I-beam front axle H Series: From R-1020 X Series: From Y-7046 Can replace the following drag links: 160959; 161329; 161378; 161870 PART NO 660699 Revision : B March 20, 2018 This revision supersedes any previous release Procedure: General revision. MATERIAL Kit #161458 includes the following parts: Part No. Description Qty 660699 DRAG LINK ASSEMBLY 1 502104 COTTER PIN 5/32X2 2 IS-13009 INSTRUCTION SHEET 1 FI-13009 FEUILLE D'INSTRUCTIONS 1 NOTE Material can be obtained through regular channels.IS-13009B Page 2 / 8 PROCEDURE CAUTION CONFORM TO THE PRESCRIBED TORQUES AND FOLLOW ASSEMBLY GUIDELINES TO ENSURE VEHICLE SAFETY. DANGER Park vehicle safely, apply parking brake, stop engine and set battery master switch(es) to the OFF position prior to working on the vehicle. PINCH HAZARD Keep hands and fingers clear of pinch zones around pitman arm. Pinch zones are between pitman arm and clamp, and between front of pitman arm and vehicle structure. REMOVAL OF EXISTING DRAG LINK 1. Raise the vehicle by the wheels using mobile column lifts. Doing so will prevent a change in direction of the knuckles and preserve the relative positions of the steering components involved i.e. the steering arm and the pitman arm. 2. Remove cotter pin and nut from drag link ball joint stud at pitman arm. 3. Disconnect drag link from pitman arm, using jaw style pullers (pressure screw type). 4. Remove cotter pin and nut from drag link ball joint stud at the steering arm (near knuckle) and then disconnect the drag link. IS-13009B Page 3 / 8 ADJUSTING THE DRAG LINK TO PROPER LENGTH - ELBOW BALL JOINT (KNUCKLE SIDE) 5. Check if the pre-adjusted length of the drag link is correct. To do so, try to install it between the steering arm and the pitman arm. If the length is not adequate, it must be adjusted to the required length. Use dimension “A” to adjust the length of the replacement drag link or you may use the replaced drag link for length reference. FIGURE 1 X3 series from Y-7046 length A = 52” 3/8”± 1/16” (1330mm ± 2mm) H3 series early model years R-1020 up to A-1604 length A = 52” 3/8”± 1/16” (1330mm ± 2mm) H3 series from A-1605 length A = 53” 3/8”± 1/16” (1356mm ± 2mm) 6. Screw the drag link elbow ball joint (knuckle side) fully in drag link tube. FIGURE 2 IS-13009B Page 4 / 8 X3 AND EARLY MODEL YEARS H3 ONLY 7. Unscrew the drag link elbow ball joint back out (not more than 1 turn) so the tapered shank points down as shown on FIGURE 1. FIGURE 3 X3 AND EARLY MODEL YEARS H3 ONLY 8. Unscrew the drag link elbow ball joint back out one (1) full turn. The tapered shank must point down as shown on FIGURE 1. 1 full turn FIGURE 4 H3 SERIES FROM A-1605 ONLY From A-1605 The limits of the adjustment sleeve do not provide enough extension. 9. Unscrew the drag link elbow ball joint out 1 inch. The tapered shank must points down as shown on FIGURE 1. FIGURE 5 IS-13009B Page 5 / 8 10. To prevent interference between the ball joint clamp bolts and other components of the steering system, the clamp bolt must be positioned vertically as shown on FIGURE 6. Tighten the clamp nut to 118-133 lbfft. CAUTION Do not re-use clamp hardware. Bolt and nut should be replaced every time they are unscrewed. While assembling the clamp, make sure the bolt does not touch the drag link tube. FIGURE 6: NOTE THE VERTICAL ORIENTATION OF THE CLAMP BOLT AT THE KNUCKLE END AND ON WHICH SIDE THE NUT MUST BE POSITIONED SLEEVE ADJUSTMENT PARAMETERS 11. On the drag link front end you will find an adjustment sleeve which has internal and external left and right threads. FIGURE 7 12. Fine adjustment of the drag link length if required should be performed exclusively by turning the adjustment sleeve while preventing the tube and joint from rotating. The only part rotating should be the sleeve To extend, turn the sleeve clockwise. To retract, turn counter clockwise. FIGURE 8 IS-13009B Page 6 / 8 GENERAL LIMITATIONS OF THE ADJUSTMENT SLEEVE Do not exceed the following maximum thread lengths and values. Max dimension V : 5/8” (16mm) ± 1 thread pitch Max dimension W : 5/8” (16mm) ± 1 thread pitch Max dimension X : 1” (25mm) Dimension V and W should be equal (V/W = 1) FIGURE 9 SLEEVE ADJUSTMENT X3 AND EARLY MODEL YEARS H3 ONLY 13. Adjust sleeve to the values of FIGURE 10. 5/8”=16mm 10/32”=8mm 14. Once the proper length adjustment is done, tighten the sleeve end ball joint clamp. To prevent interference between the ball joint clamp bolts with other components of the steering system, the clamp bolt must be positioned horizontally as shown on FIGURE 11. Tighten the clamp nut to 118-133 lbf-ft. FIGURE 10 CAUTION Do not re-use clamp hardware. Bolt and nut should be replaced every time they are unscrewed. While assembling the clamp, make sure the bolt does not touch the drag link tube. FIGURE 11: NOTE THE HORIZONTAL ORIENTATION OF THE CLAMP BOLT AT THE SLEEVE END AND ON WHICH SIDE THE NUT MUST BE POSITIONED IS-13009B Page 7 / 8 H3 SERIES FROM A-1605 ONLY 15. Adjust sleeve to the values of FIGURE 12. 16. Once the proper length adjustment is done, tighten the adjustment sleeve clamp. To prevent interference between the ball joint clamp bolts with other components of the steering system, the clamp bolt must be positioned horizontally as shown on FIGURE 13. Tighten the clamp nut to 118-133 lbf-ft. CAUTION FIGURE 12 Do not re-use clamp hardware. Bolt and nut should be replaced every time they are unscrewed. While assembling the clamp, make sure the bolt does not touch the drag link tube. FIGURE 13: NOTE THE HORIZONTAL ORIENTATION OF THE CLAMP BOLT AT THE SLEEVE END AND ON WHICH SIDE THE NUT MUST BE POSITIONED DRAG LINK INSTALLATION 17. Install the drag link. 18. Secure the ball joint with a castellated nut at both ends. Tightened the castellated nuts to 150-200 lbf-ft. 19. Install cotter pin p/n 502104 at both ends to secure the ball joint nut and bend to lock bolt in place (see an example of a correct installation of a cotter pin on the image below). 20. Apply a small amount of anti-seize compound on all exposed threads for corrosion protection. Be sure to avoid smearing the ball joint boot.
