Service Manual

RECENT MODIFICATIONS IN MODEL 140 and 147
1. The Check Valve, 140-6 and O-Ring, 130-32 assembly has been replaced by a solid Teflon Check
Valve, 140-6T. When it is necessary to replace this assembly, the new Teflon Check Valve, 140-6T
should be used on all models.
2. A modification has been made in the method of securing the Trigger Casing Assembly to the
gun. When it is necessary to repair a gun having the new Trigger Casing Assembly, all the
changes as described in drawing 5.5 must be made, these changes are as follows:
a. Replace 140-13 Rear Breech Screw with 140-97 Screw and Washer Assembly.
b. File corners of Trigger Casing as noted on Drawing. 5.5.
c. Use a 140-95 Lockwasher under the head of each casing screw. (No's 140-59 and 140-62.)
d. Replace Knurled Locating Screw Nut, 108-14 with the 140-94 Locating Screw Nut. Use a 140-
47 Washer under the nut. NOTE: This change must be made on all guns of this model.
3. A nylon detent has been incorporated in the lever link to hold the lever in the up position. When
repairing a gun having this type of lever, the pump should be set so that the plunger just touches
the valve at the bottom of its stroke. There should be no resistance due to the pump rod
bottoming on the end of the valve.
