Drain reservoir into a suitable container.
5. Disconnect remaining hydraulic hoses from reser-
voir. Label the hydraulic hoses to show their correct
position on the reservoir for assembly purposes.
6. Remove hydraulic reservoir using Figure 112 as a
guide.
7. If hydraulic fittings aretoberemoved from reservoir,
