CENTER HINGE ADJUSTMENT
00074
1. Place boom and bucket control lever in FLOAT position (WP 0005).
2. Adjust hinge spacing so frame tongues (Figure 2, Items 4 and 7) are centered between rear frame ears
(Figure 2, Items 3, 5, 6 and 8), such that A dimensions as shown in Figure 2 are the same. (A dimension may
not be the same as B dimension.)

WARNING
Do not loosen bottom nut more than 30. Failure to follow this warning may result in injury
or death to personnel.
3. Loosen bottom nut (Figure 3, Item 10) before any adjustment.
4. If front frame tongues are too high, loosen top nut (Figure 3, Item 1) until tongues are centered.
5. Install retainer plate (Figure 3, Item 2). Note that two retainer plate positions are available by turning plate over.
6. Once adjustment has been made, tighten bottom nut (Figure 3, Item 10) to 225 to 250 lb-ft (305 to 339 Nm) to
seat mating parts in hinge assembly. Loosen bottom nut.
7. Tighten bottom nut (Figure 3, Item 10) using retainer plate (Figure 3, Item 9) as a wrench. Hinge should be just
snug at this point. DO NOT OVER-TIGHTEN.
8. If holes in retainer plate (Figure 3, Item 9) line up with tapped holes in frame, install plate. Note that two
positions are available by turning retainer plate over.
9. If holes in retainer plate (Figure 3, Item 9) do not line up with tapped holes in frame (in either retainer plate
position), loosen bottom nut (Figure 3, Item 10) until plate holes line up with frame holes. (Because two retainer
plate positions are available, the amount of nut loosening required will always be less than 30.)
10. Install retainer plate (Figure 3, Item 9).
11. Lubricate upper and lower hinges (WP 0018).
