TLD-2500 TUBE TESTING GUNS
OPERATING INSTRUCTIONS
4. Replacing the Shaft Support Tube Assembly:
The TLD Test Guns are shipped from the factory with three sets of seal stems (Fig. 1 & Fig. 2
Item 3) tube assemblies. Tube test inside diameters (ID) are:
Stem I - .28” - .48” (7.1 mm – 12.3 mm)
Stem II - .49” - .83” (12.4 mm – 21.2 mm)
Stem III - .84” - 1.23” (21.3 mm – 31.3 mm)
1. Remove all seal and washer sets as described in “Installing Replacement Seals” on page 3.
2. Using an open ended wrench on the wrench flats machined on the actuating piston (Fig. 1
& Fig. 2 Item 5) and a pipe wrench on the seal stem (Fig. 1 & Fig. 2 Item 3), loosen the tube
from the piston inside the cylinder in a counter clockwise manner.
3. Determine the correct size seal stem that is required for the tube ID being tested. All three
seal stems are the same dimension at the cylinder base to fit into the piston. Use PTFE
tape or similar product to lubricate and seal threads. Do not over tighten seal stem when
reinstalling.
4. Inspect the seal stem for any scars left from disassembly or reassembly phases. File or sand
smooth if any irregularities exist.
5. Reinstall seal and washer sets per previously outlined procedure in “Installing Replacement
Seals” on page 3.
