APPENDIX B

HULL/EJECTOR INTERFERENCE MODIFICATION

PURPOSE:

The purpose of the Hull/Ejector Interference Modification is to eliminate contact between the new pressure relief

valves, located below the main hydraulic filters, and the ejector when it is fully retracted. This is accomplished by

adding a spacer block behind the ejector cylinder mount. To accommodate the extra travel distance of the ejector

rollers when the ejector is fully extended, wheel support wedges are welded to the hull in bowl area.
