Groeneveld TWIN 2, TWIN 3 Parts Catalog

I’ve been wrenching for 28 years, and I can tell you the difference between a genuine parts catalog and a xeroxed mess. This one’s the real deal. Groeneveld TWIN 2, TWIN 3 Parts Catalog – a factory OEM document that gives you 212 pages of exploded views, part numbers, and callouts for every component in the TWIN 2 and TWIN 3 grease pump systems. If you’re maintaining a fleet of automated lubrication systems on earthmovers, mining trucks, or industrial machinery, you need this on your tablet, not some third-party PDF that swaps a M16x1.5 fitting for a 5/8-UNF and then you’re chasing leaks all afternoon.

Twin Pump Breakdown: 12cc/24Vdc/2L/250bar

Open to the twin_pumps section (17_1) and you get the full parts list for the pump assembly. Item numbers cross-reference to the drawing: reservoir guide pin, cover with O-ring, reservoir kit, follower plate, support, cable harness, body, grease outlet M16x1.5, filter kit, pump unit, test button kit, low level switch, sealing kit, timer clip, control unit, protective cover. The table on page 4 lists every kit number – F112484 for the 2-liter, 24Vdc pump, F111956 for 3-liter, F111842 for 4-liter. All metric specs as OEM intended. If you need imperial conversions, do the math yourself. Aftermarket? Don’t bother.

Brackets and Mounts: Factory Fitment

Section 17_2 covers brackets – 9 sub-sections (17_2_1 through 17_2_9). Each one shows the exact mounting plate, bolt pattern, and orientation for installing the pump on a chassis or frame rail. I’ve seen people use generic L-brackets and wonder why the pump vibrates loose. Use the factory bracket listed here and you won’t have that problem. The parts catalog doesn’t give torque specs for the bracket bolts, but if you’re smart you’ll hit them with a torque wrench anyway – those pumps see 250 bar of pressure and will shake anything loose that’s not properly torqued.

Wiring Diagrams or Guesswork? The Electrical Parts Section

Section 17_4 (electrical_parts) includes cable harness drawings and connector pinouts. You get the pump cables section (17_3) and pressure switch cables (17_5) as separate PDFs within the catalog. The low-level switch test circuit wiring is shown with item numbers. For installation steps, grab the Groeneveld TWIN-3 858 Installation Manual – this catalog alone won’t teach you how to wire a control unit, but it will tell you exactly which cable harness part number to order. That’s the whole point of a parts catalog.

7 Coupling Types and 9 Hose End Fitting Groups

Section 17_7 (couplings) breaks down 9 sub-sections covering different coupling styles – from straight to 90-degree to banjo. Section 17_8 (hose_end_fittings) gives you 9 more groups for crimp-on and reusable fittings. Need a special connection? Section 17_11 covers adapters and custom blocks. This catalog doesn’t leave you guessing which fitting goes where; it shows the O-ring seal part number and the thread size. Background on lubrication system design? Read the Automotive Industry Overview for context, but for part numbers, stick here.

Check the Tools Section Before You Start

Section 17_14 (tools) lists the special tools required to service these pumps – ring spanners, seal drivers, and the test button tool (item 87401, page 5). Don’t start a pump rebuild without confirming you have the tool for the filter kit retaining ring. Nothing worse than getting halfway through a seal replacement and realizing you need a tool you don’t own. This catalog saves you that trip to the tool truck.

Source Validity: OEM Groeneveld Documentation

This is not a reprint or a third-party scan. It’s the original Groeneveld Parts Manual F210846R00, 212 pages, released by the manufacturer. The cover page clearly states “Parts & Accessories TWIN 2 & 3” with the Groeneveld logo. I’ve seen aftermarket catalogs that list the wrong reservoir kit for a TWIN 2 because someone mixed up the 2-liter and 3-liter follower plates. That doesn’t happen here because the OEM part numbers are verified. For the engine-side applications (diesel engines on heavy equipment), check the Internal Combustion Engine resource – but for the lubrication system itself, this catalog is the final word.

Who Actually Needs This Catalog?

If you’re a home-garage mechanic who owns a piece of equipment with a Groeneveld TWIN 2 or TWIN 3 pump, you need this. If you’re a fleet maintenance shop that sees these pumps every week, you need this. If you’re a parts counter guy trying to look up a hose end fitting for a customer, you need this. Beginners will appreciate the clear exploded views; experienced techs will appreciate having the factory part number instead of calling the dealer and being put on hold. The only people who don’t need it are those who enjoy ordering the wrong part twice.
