Terex PT-70 2010 Parts Catalog – Factory OEM Parts Breakdown

If you have ever ordered a replacement hydraulic hose for a PT-70 only to get the wrong bend angle, you know the frustration. Aftermarket parts lists are guesswork. With this 33-page factory Terex PT-70 2010 Parts Catalog, you get the exact OEM part numbers sorted by serial number breaks. No guessing which revision of the undercarriage you have. The manual carries part number 2046-306 and was printed 09-10. That matters because Terex changed components mid-production – and this catalog accounts for every one of them.

Assembly Groups by Serial Number – Why It Matters

The PT-70 went through at least two major undercarriage changes around serial DTH 00720. This catalog splits sections 17 (right undercarriage) and 18 (left undercarriage) into sub-sections 17-A for serials DTH 00682-00719 and 17-B for serials DTH 00720-current. If you order chain adjuster parts without checking your serial, you’ll get the wrong components. The same serial-number logic applies to every assembly – cab, hood, hydraulic reservoir, lift arm control valve, engine, and even the optional air conditioning package. You’ll find the exact breakdown starting on page 1 of the catalog.

Hydraulic System Parts – Pumps, Valves, Cylinders

One section covers the Hyd. Drive/Auxiliary Pump Assembly (Section 11). Another isolates the Pilot Generation Block (Section 12). If your PT-70 loses pilot pressure, you can pin down the block part number and o-ring kit without tearing the whole system apart. The Lift Arm Control Valve Assembly (Section 10) and Cylinder Service Items section list current hydraulic cylinders with manufacturer part numbers. Don’t trust a universal seal kit – get the OEM part that fits your serial range.

Engine and Powertrain Breakdown

Engine Assembly (Section 13) and Intake/Exhaust Assemblies (Section 14) give you the full air and fuel system parts. The Torsion Axle Assembly (Section 16) and Drive Table Assemblies (Sections 19 and 20) cover the drive train. Every part has a Terex number – not a vague “fits many models” aftermarket number. Need a fan belt or primary air filter? Those are listed in the General Service Items section on page 3. Belt part numbers, filter numbers, oil filter – all factory-specified.

Cab and R.O.P.S. Exploded Views

Sections 1 through 4 cover the Cab (R.O.P.S.) Assembly, Cab Interior, Cab Door (optional), and Enclosed Cab (R.O.P.S.) assembly. Each section starts with an exploded diagram and a parts table. If your cab door latch broke, you get the spring, handle, and hinge part numbers. The optional A/C and heater assemblies are in Sections 25 and 26 – complete with compressor and evaporator part numbers. You can cross-check the part against your actual machine before ordering.

General Service Items & Lubricants – Page 3

Flip to page 3 and you get a quick-reference list of engine oil filter, primary and secondary air filters, diesel fuel filter, fan belt, A/C belt, antifreeze/coolant (by the gallon or case), and engine oil (quart or case). No need to cross-reference a separate service manual for routine maintenance parts – it’s all here. If you prefer the full service procedure, pair this parts catalog with the TEREX PT-70 PT-80 2009 Service Manual”>TEREX PT-70 PT-80 2009 Service Manual for torque specs and repair steps.

Source Authenticity – OEM vs. Aftermarket

Aftermarket parts catalogs often combine multiple machine models into one list and omit serial number splits. That leads to wasted return shipping and downtime. This is a direct Terex factory print – not a reprint or third-party compilation. The document structure mirrors the original binding. You can verify the part number (2046-306) and print date directly on the first page. For a compact track loader that works in mud and gravel, you need the right undercarriage part the first time. This catalog gives you that. See the Terex PT-70 2010 Parts Catalog – OEM Factory Manual”>Terex PT-70 2010 Parts Catalog – OEM Factory Manual page for the full product details.

Every part number in this catalog comes from Terex’s own engineering release – not a dealer’s guess.

Frequently Asked Questions

Does this parts catalog include torque specifications?

No – it is a parts catalog, not a service manual. Torque values belong in the factory service manual.

Why are there different serial number ranges for the undercarriage?

Because Terex changed the drive sprocket and chain design after serial number DTH 00720. The catalog splits Sections 17 and 18 into 17-A for serials 00682-00719 and 17-B for 00720-current. If you order a sprocket for serial 00685 using the later section, you will get the wrong part – the bolt pattern and tooth count differ. Always confirm your machine’s serial number before placing an order. The manual lists each assembly with the exact serial range it covers, so you match parts to your machine’s build date.

If you need to replace a hydraulic cylinder, a fan belt, or a cab seal, do it once with the right part number. This 33-page catalog puts every Terex PT-70 component in front of you with serial-specific breakdowns. Access the Factory Manual now and keep your PT-70 running without ordering twice.
