The piston Hand rotary valve E are inserted in the cylinder D , itmatches, the position with the plug S in outer of O-ring04 and rotary valve E is built, and it tightens with thesocket head cap screw 03 lightly.(Please be suitable and confirm it by the mark.)(Fig. 6and 9)10 ) Under such a condition, please install it in the spindleonce. And, please do the wick match so that run-out ofthe cylinder D and rotary valve E may become smallas much as possible. Afterwards, please tighten with thesocket head cap screw 03 .(run-out must aim at 0.01TIR or less.)(Fig. 10)Fig. 9Fig. 10KITAGAWA IRON WORKS CO., LTD.

It enters smoothly when doing while lightlybeating with the hammer etc. with a ring form specialjig in a right picture. At this time, please build it innoting that the sleeve doesn't twist. (Fig. 11)MANAGER CHIEF WRITE BY高 橋 優12 ) Flinger N is inserted in rotary valve E . Afterwards,please arrange the plug insertion hole and thedirection of the sleeve G and build in the sleeve bodyF .13 ) The plug L is wrung. (Fig. 2)14 ) The stopper L is installed with the socket head capscrew 02 . (Please insert S2091 or more withoutforgetting sheat-packing (C).)(Fig. 1)15 ) The fan K and fan-cover J are obtained with aCross-recessed head machine screw 14 、20 . (Fig. 1)16 ) After assembly, the cylinder is installed in the spindleaccording to the above-mentioned procedure.Afterwards, please adjust it so that run-out at theinstallation may become 0.015TIR or less by outer ofrotary valve E and 0.01TIR or less by outer ofsleeve body F .Fig. 1117 ) Please use it after laying pipes after assembly iscompleted and confirming operation.Notes of assembly・ When O-ring and the oil seal are damaged, it causes the oil leakage. Therefore, please assemble itmight not spread oil enough on the sliding area and each part O-ring, and to damage it.・ At assembly, When garbage etc. enter in the cylinder it causes overheating. Please assemble itvery carefully.KITAGAWA IRON WORKS CO., LTD.
