An Enerpac hydraulic pin puller uses a hollow cylinder and stackable columns to pull seized pivot pins out of excavators, loaders, cranes and other heavy equipment, without hammering. Enerpac makes two kits: the PPH40 (40 ton) and the PPH66 (66 ton).
PPH40 vs PPH66
| PPH40 | PPH66 | |
|---|---|---|
| Pulling capacity | 40 ton | 66 ton |
| Cylinder stroke | 3.94 in (100 mm) | 3.94 in (100 mm) |
| Cylinder oil capacity | 31.18 in³ | 51.68 in³ |
| Standard quick nut | 1-1/4"-12 UNF | 1-1/2"-12 UNF |
| Kit weight | 22.1 lb | 48.9 lb |
| Cylinder | Single-acting, spring return, 10,000 psi | |
Each kit includes the hollow cylinder with coupler, three column sections, the standard quick nut, an eyebolt, a shackle and a storage case. The threaded pulling rod, pump and hose are not included.
What you need to pull a pin
- A threaded rod through or into the pin, and a quick nut that matches its thread. 40 ton quick nuts: 1"-14, 1-1/4"-12, M27, M30, M33. 66 ton quick nuts: 1-1/4"-12, 1-1/2"-12, M36, M48.
- Enough column height to clear the pin. Add PPH40C or PPH66C locking columns for longer pins.
- A single-acting pump that holds more oil than the cylinder plus hose. A P392 (55 in³) covers the PPH40. For the PPH66, use a P80 (134 in³) or a cordless XC2202MB.
Pin puller questions
What if the pin is longer than the stroke?
The cylinder stroke is 3.94 in. Longer pins are pulled in steps: retract the cylinder, run the quick nut down the rod, and pull again. Locking columns add height when the pin must travel farther.
Which pin puller do I need?
Use the PPH40 for pins that need up to 40 tons to break free and the PPH66 above that. Seized pins often need far more force than a clean pin, so when in doubt, size up.
Are service parts available?
Yes. Quick nut service kits (PPH40QK, PPH66QK), saddles, adaptor plates, lock keeper plates and eyebolts are listed below. We also repair Enerpac pin pullers. See Enerpac repair service.
