Dry / sealed tracks
A sealed track is not necessarily oil-lubricated. Identify the track design, pins and bushings before selecting tooling.
TRACK, PIN AND MACHINE
Pin diameters by machine and track design
Track pin presses are used to service steel link tracks on excavators and dozers. For Caterpillar, Hitachi, Liebherr, Komatsu and Volvo, the installed track design determines the appropriate setup.

Pin diameters by machine and track design
Dimension examples for initial orientation. Always retain the model suffix and track type: “D6” alone is insufficient.
| Manufacturer | Model / variant | Track type | Approx. pin Ø [mm] |

| Caterpillar / Cat | D5K | SALT | 33.5 |
| Caterpillar / Cat | D6H | SALT | 44.5 |

Orientation values researched from tooling charts, converted from inches and rounded to 0.1 mm. Not OEM approval or machining dimensions. The source lists generic pin dimensions; a separate master pin size is not identified for every row. Year, serial number, replacement track and pin type may differ. Check the actual pin before selecting equipment. SEALED = sealed track; SALT = sealed, oil-lubricated track.
D4, D5, D6, D8, D9: The variant matters.
These designations identify Caterpillar dozers. Even D6H and D6N have different pin diameters in the SALT examples listed. LGP (low ground pressure), HD versions and additional pin retention such as PPR also need consideration. A machine series is not a unique track part number.
Track types and manufacturer details
Which track is on your machine?
Track pin presses are used to service steel link tracks on excavators and dozers. For Caterpillar, Hitachi, Liebherr, Komatsu and Volvo, the installed track design determines the appropriate setup.
Distinguish lubrication from the track joint
Grease-lubricated tracks · GST / GLT
Grease lubricates the pin-to-bushing joint. Komatsu uses GST and Caterpillar uses GLT. These terms do not specify a common pin size.
Oil-lubricated tracks · SALT
Sealed joints retain oil between pins and bushings. These undercarriages are documented on dozers, among other machines. Seals and assembly requirements must be considered.
Master pin joints
A special pin joins the track ends. A press-fit master pin needs matching pushing and receiving tooling; its design can differ from regular track pins.
Split master links
A split master link is a different joint design from a press-fit master pin. Establish whether the job is to open the track or service another track joint.
Endless rubber tracks
An endless rubber track does not have a removable master pin like a steel link track. No HTPP suitability is stated here for these tracks.
Track designs documented by machine manufacturers
| Manufacturer | Documented example | For your enquiry |
|---|---|---|
| Caterpillar / Cat | Cat documents GLT tracks with press-fit master pins. | Provide the machine model, serial number and part number of the installed track. |
| Hitachi | Hitachi lists dedicated pins and master pins for Selected Parts tracks, including ZX200 applications. | Hitachi states that Selected Parts internal components are not interchangeable with genuine track internals. Identify the track variant. |
| Liebherr | Liebherr lists oil-lubricated tracks and split master links for PR 746 / PR 756. | Photograph the joint and describe the intended work. |
| Komatsu | Komatsu distinguishes excavator GST from dozer SALT, with additional systems such as PLUS. | Specify the exact undercarriage design and pin and track dimensions. |
| Volvo CE | Volvo offers different undercarriage parts ranges as well as rubber tracks. | Distinguish steel link tracks from rubber tracks; identify installed parts and dimensions. |

What helps us select your equipment
Request a check of your pin dimensions- Machine manufacturer, model and serial number
- Track manufacturer and part number, if known
- Pin diameter and length; track pitch (pin-centre spacing)
- Track width at the pressing point, clearance and photos of the pin and joint
- Required work: open the track, remove or install a pin

FAQ
Good questions. Clear answers.
01Will a track pin press fit Caterpillar, Hitachi, Liebherr, Komatsu or Volvo?
The brand alone is insufficient. Selection depends on the installed track, joint, pin dimensions, clearance and required force. WSD reviews the appropriate Power Team HTPP setup using your information.
02What does Master Pin Pusher mean?
A Master Pin Pusher is a press for the track master pin. Track Pin Press is another common term. The available pin operations depend on the press, tooling and track design.
03Is 100 tonnes enough for my excavator track?
Force alone does not determine suitability. Pin dimensions, frame opening, throat depth, tooling and track condition must also match. The HTPP-100 data sheet specifies tooling for pin diameters of 19.3–60.2 mm; this is not universal machine approval.
