RE-ASSEMBLY
Refer to Section 6.0 for parts lists. All numbers below refer to location numbers in Figure 6.4-1.
IMPORTANT:
1. Thoroughly clean all parts prior to reassembly.
2. Check to see if O-rings are installed toward the hydraulic flow with Teflon backup rings
behind.
1. Place the sleeve (5) into front of housing (2) as shown (note the orientation).
2. Replace the puller unit sleeve retainer (6) and tighten until snug.
3. Install the piston assembly (3) into the housing (2) by gently threading the piston through the sleeve (5).
Then push the piston (3) to the full forward position. Lubricating the piston rod and threads with hydraulic
oil will help prevent damage to the sleeve seals.
4. Install the handle assembly (11) with hydraulic adapter onto the housing (2) using four hex-head bolts. The
Teflon backup rings (2, Figure 6.2-1) may be partially sheared off during the installation process. Remove
the bolts and handle assembly to remove any Teflon material sheared off during the installation process. Re-
install the handle assembly (11) onto the housing (2) using four hex-head bolts.
5. Install the air seal adapter (7) on the piston rod assembly (3). Install the spring pin (26) if present.
6. Install the threaded adapter (8) or chuck assembly.
7. Reassemble the barrel (4) to the housing (2).
8. Install the end cap (9) and tighten the lockring (10).
9. Select the appropriate mandrel/nosecap combination and install.
