ASS&~BLYANDDISASSEMBLY 54. Disassembly and reassembly of most elements of the projectile hoists are readily apparent from the general arrangement drawings. The speed gear and the hoist hydraulic cylinder are exceptions, the former is disassembled according to the instructions for the A-end unit as described in. chapter VIII. Instructions as to removal of the hydraulic cylinder are given in paragraph 55. 55. Hydrau lie cy l i.nd er remoua l. - Because of the size, posi tion and arrangement of the hydraulic cylinder, removal is difficul t. The following outlined routine will enable removal
256 without dis~urbing any of the hoist casLlngs. This operation is prescribed for disassembly of the piston group. The reassembled cylinder can be installed in the ~everse procedure. (a) Disconnect the pipe flange (216383-2) from the upper cy.l i.nder- head (216381-1~ center and left hoists; 216381-2, right hoist) and lower cylinder head (216382-1). (b) Remove set screw (12-2-4-112) from piston rod (216380-2) and drive piston pin (216384-2) from crosshead (230700-1, center hoist; 230701-1, right hand or left hand hoists). (C) Disassemble the four bolts that secure upper cylinder head (216381-1, center and left hoists; 216381-2, right hoist) to the intermediate r~ck casings (230711-1 and 230719-1, center hoist; 217294-1 or2 and 217295-1 or 2, right hand'and left hand hoists) and remove the two' keys (216384-4) from same. (d) Lower the hydraulic cylinder approximately 30.0 inches so that the' upper cylinder head 1rTill clear the upper proj ectile handling platform (230702-1, center hoist; 230723-1 or 2, right hand or left hand hoist). ( e) Tilt the hydraulic cylinder to the side (for center hoist) and to the rear (for right hand and left hand hoists) and remove.
