10. Install two new Autolube Hoses (6) as shown from Connection Block (8) on engine frame to the Autolube Pump (B) at back of the machine. Refer to Illustration 6.

11. Secure Autolube Hoses (6) using five Clips (9) and retained Bolts (E) and Washers (F). Refer to Illustration 6.

12. Install two shorter Autolube Hoses (7) as shown between Distribution Valve (C) at machine hitch area to Connection Block (8) on engine frame. Refer to Illustration 6.

13. Install two new Clips (3) on shorter Autolube Hoses at machine hitch area. Reuse the bolts and washers retained from earlier removal of old configuration. Make sure that the left edge of green locating tape on shorter Autolube Hoses (7) aligns to the left edge of left hand Clip (3) at the machine hitch. This action will ensure maximum slack in the hoses at machine hitch for all articulation positions. Refer to Illustration 6.
