Cat D10 Series Dozer Hydraulic Cylinders
This category covers ripper cylinder groups, ripper pin puller cylinders, and hydraulic cylinder tubes for Caterpillar D10 series crawler dozers — the D10N, D10R, D10T, and D10T2. The D10 is one of the largest production dozers Caterpillar builds, and its ripper and blade cylinders handle enormous loads breaking rock and moving overburden. Broken Tractor stocks complete ripper cylinder groups, pin puller cylinders, and replacement tubes ready to ship, all built to accept OEM-style seal kits.
Fits Models At A Glance
D10N, D10R, D10T, D10T2 — with shared ripper and pin puller cylinders fitting 854G wheel dozers and the full D8, D9, and D11 ripper lineup
Fitment note: Verify your serial number, blade configuration (SU or U), and ripper type (single-shank vs multi-shank) before ordering. The pin puller cylinder is shared across the D8 through D11 range, but the ripper lift and tube parts are specific to the D10.
What's In This Category
Ripper Cylinder Groups
Ripper cylinder group (1926446) for the 854G wheel dozer, D10R, and D10T. This is the heavy lift cylinder that raises and lowers the rear ripper beam on single-shank and multi-shank setups. The D10 ripper runs both lift and tilt cylinders, so confirm which function you need before ordering.
Ripper Pin Puller Cylinders
Ripper pin puller cylinder group (6E3113) — one of the most widely shared cylinders in the Cat dozer line, fitting the D8N, D8R, D8R II, D8T, D9N, D9R, D9T, D10N, D10R, D10T, D10T2, D11, D11N, D11R, D11T, and DV232. The pin puller hydraulically pulls the shank pin so the operator can change ripper shank depth without leaving the cab.
Hydraulic Cylinder Tubes
Semi-finished left-hand cylinder tube (9J0669) for the 977K, 977L, and D10N. Replace the tube when the bore is scored but the rod, gland, and piston are still serviceable — a big cost saver on cylinders this size.
Fitment Tip
The D10 splits into two eras. The D10N is the older elevated-sprocket machine and shares the 9J0669 cylinder tube with the 977K and 977L track loaders. The D10R and D10T are the modern high-drive machines and use the 1926446 ripper cylinder group. The 6E3113 ripper pin puller cylinder is the exception — it's a common part that crosses the entire large-dozer range from the D8 up through the D11. When ordering ripper cylinders, confirm your ripper configuration (single-shank vs multi-shank) and serial number, since the ripper lift and tilt cylinders differ by setup. The D10 serial number is on the rear of the machine, left side, high on the frame rail, and is usually hidden by the ripper. Pre-2001 machines use an 8-digit serial (like 3KR00424 or AKT00311); 2001 and newer use a 17-digit VIN. Call us with your serial and configuration and we'll confirm the right cylinder before you buy.
Frequently Asked Questions
What ripper cylinder fits my Cat D10R or D10T?
The ripper cylinder group 1926446 fits the D10R and D10T, along with the 854G wheel dozer. It's the main ripper lift cylinder for raising and lowering the rear ripper beam. The D10 ripper uses both lift and tilt cylinders, so confirm whether you need the lift group, the tilt cylinder, or the pin puller before ordering, and verify your single-shank or multi-shank configuration.
Does the ripper pin puller cylinder 6E3113 fit other Cat dozers besides the D10?
Yes — the 6E3113 ripper pin puller cylinder group is one of the most widely shared cylinders in the Cat dozer line. It fits the D8N, D8R, D8R II, D8T, D9N, D9R, D9T, D10N, D10R, D10T, D10T2, D11, D11N, D11R, D11T, and DV232. If you run multiple large dozers, this is a common spare worth stocking since it covers the whole fleet.
Can I replace just the cylinder tube on my Cat D10N?
Yes. The semi-finished left-hand cylinder tube 9J0669 fits the D10N, along with the 977K and 977L track loaders. If the cylinder bore is scored but the rod, gland, and piston are still good, replacing just the tube saves money over a complete cylinder. Because it's a semi-finished tube, confirm your machining requirements before ordering. Inspect the rod and gland first to make sure they're reusable.
What's the difference between the D10N and the D10R/D10T cylinders?
The D10N is the older elevated-sprocket machine and uses the 9J0669 cylinder tube shared with the 977K and 977L loaders. The D10R and D10T are the newer high-drive production machines and use the 1926446 ripper cylinder group. They don't interchange on the main cylinders. The one part they all share is the 6E3113 ripper pin puller cylinder, which spans the entire large-dozer range.
Why is my Cat D10 ripper slow to raise or won't hold position?
On a D10, a slow or drifting ripper usually points to worn internal seals in the ripper lift cylinders or a leaking control valve. These are very large high-pressure cylinders, so even minor internal bypass shows up as visible drift. Pressure-test the cylinders individually — if they hold when plugged but drift when reconnected, the control valve is the issue. If the cylinder bypasses internally and the bore is scored, replace the tube or complete group rather than reselling.
Where is the serial number on a Cat D10 dozer?
On the D10 and other large Cat dozers, the serial number is on the rear of the machine, left side, high up on the end of the left frame rail — it's usually hidden by the ripper attachment. Pre-2001 machines use an 8-digit serial (like 3KR00424); 2001 and newer machines use a 17-digit VIN. You need this number, plus your blade and ripper configuration, to order the correct cylinder.
