system for the non-ferrous head, using a ferrous cover plate. This plate will need to be modified, adding a discharge tube
connection. (Ref 2)
WARNING!!!!!
ONLY A SLING APPROVED BY OSHA AND THAT IS RATED FOR THIS WEIGHT SHOULD
BE USED.
C. Move all tubing and wiring clear of the head, and CAREFULLY AND SAFELY place a sling or strap around the
head. This sling will be used in lifting the head from the column, so take care in placing this strap.(Figure B ref 3)
Step 3: Removing the gib plates. (Figure B ref 5/6)
A. With the head securely strapped, loosen and remove booth head lever cams from the “T” slot in the head. (Ref 4)
B. Remove the set screw from the lower lock nut on the head feed cylinder piston. (See gib plate detail drawing. ref A)
If this screw and nut are behind an obstruction, remove the upper and lower air lines, from the fittings on the head feed
cylinder. Place a compressed air nozzle in the upper or lower fitting on the cylinder, and move head up or down to
clear obstruction. (Move hoist with the strap to allow movement.)
C. Remove the lower locking nut from the head feed cylinder piston. (Ref b on gib plate detail drawing)
D. With the head disconnected from the head feed cylinder, gently lower the head down using the strap and hoist.
Lower until head has cleared the piston.
E. Eight allen head bolts hold the two gib plates to the head. From the back of the column remove these eight bolts.
(Ref C on gib plate detail drawing) Note: These bolts may be quite tight. An impact wrench may be useful for this.
Note: Step 6 may need to be repeated to raise or lower the head to allow access to the bolts.
F. With the eight bolts removed, carefully remove the two gib plates from the machines, and place in a safe location
where no damage will come to them. (Mark left top / right top for future installation)
Step 4: Removing the head.
A With all tubes, wires, etc. clear from the head, pull the head away from the column, (figure C ref 7) using a strap and
hoist. (Fork lift or engine hoist can be used)
Warning!!!!!
Head may be difficult to balance. Take caution when lifting the head
B Using extreme care set the head in a safe location in an upright position.
REPLACEMENT HEAD INSTALLATION
Installing head onto the column
A. Wipe all way surfaces clean of debris. Wipe the rear machined surfaces and oil galley rings of the head, clean of
debris.
B. With the replacement head carefully strapped and hooked to a hoist etc., lift the head to the column, and insert
between ways (figure D).
Note: When placing the replacement head keep it low on the column, below the cylinder piston threads.
Installing the gib plates
A. The gib plates that came with this head may need some grinding or adjusting. This procedure is a one time
operation, and will not be needed on future installations.
B. Bolt the two gib plates to the back of the head in reverse order from above. (Figure E ref 5)
C. Attempt to wobble these gib plates while on the machine. If they are tight, grasp the head and try to move it side to
side. Watch for gaps at the ways when moving the head side to side.
D. If there is slight movement, tighten the gib blocks up a half turn at a time. Adjustments are made with the screws
threaded into the top of the gib block, as shown in gib plate detail drawing ref e. (The two rear plates will show gaps
when the head is moved front to back, (Adjust the back gibs) the gib plate on the side will be responsible for side to
side movement. (Adjust these gibs for side to side movement)
Note: Refer to gib block adjustment.
E After any gib block adjustments are made, the head must be tested for free travel. Using the strap raise and lower the
head on the column and check that the head travels the full length of the column, without binding or jerking. There will be a
