Reassembly
1. Replace all o-rings and backup rings on the inside and outside of the brass sleeve (7). Drop the brass
sleeve into the front of the housing (1). Turn the brass sleeve until the hole is aligned with the matching
hole in the bottom of the housing.
2. Install new 1046-045 o-rings and 1046-044 backup rings on the transfer tube (part of the handle sub-
assembly). Note that the o-rings go on the ends of the tube and the backup rings will be towards the
middle.
3. Place the small 1046-012 o-ring in place on the housing before installing the handle. Install the handle
assembly (6) onto the housing with four socket-head screws, using a 5/32-inch hex driver. The transfer
tube will go into the hole in the brass sleeve, which was aligned in Step 1.
4. Replace the rear cylinder (2) and tighten until snug using a strap wrench. Tighten the lockring (9) against
the housing using the spanner wrench (30).
5. Replace 1046-113 T-seal on the end of the piston assembly (4). Backup rings are included with T-seal,
these are installed on both sides of the seal.
6. Install the threaded end of the piston assembly (4) into the housing (1). Thread the piston through the
housing and push to the full forward position.
7. Replace 1046-043 U-seal on back end of threaded adapter or chuck assembly (17).
8. Wrap Teflon tape around the threads of the piston rod, then install the threaded adapter or chuck
assembly (17). Tighten the locknut (10) against the threaded adapter or chuck assembly using two
1-5/16-inch wrenches.
9. Replace 1046-058 o-ring and install the front barrel (5). Tighten with a strap wrench, then tighten the
lockring (8) against the housing using the spanner wrench (30).
10. Install the end cap (5) and tighten using the spanner wrench (30). Next, tighten the lockring (9).
11. The puller is now ready for use. Select the appropriate mandrel/nosecap combination and install.
Important: (1) Thoroughly clean all parts prior to reassembly.
(2) Install o-rings toward hydraulic pressure, with backup rings “behind.”
