Rammax RW 1504 HF, RW 1504 HK, RW 1504 HFK Parts Catalog – Factory OEM Specs

If you’re rebuilding a vibratory trench roller and the exploded diagram you obtained looks like it was faxed three times, I know exactly where you’re at. Twenty-eight years wrenching on German iron has taught me one thing: aftermarket parts lists for these Rammax rollers are garbage. The Rammax RW 1504 HF, RW 1504 HK, RW 1504 HFK Parts Catalog is the only document that shows you the real exploded views with genuine factory part numbers. No reprints. No third-party garbage. This is the original print from Rammax, valid as of serial number 1506704.

That 129-page catalog covers everything from the drum bandage to the Dieselmotor mounting. You’ll find the exact scraper sets, crankcase bolts, and even the HD-hose routing. Page 5 lists the 3-90206 scraper set for the 630mm standard drum and the 3-90200 drum set for the 850mm version. Need the engine side? The Dieselmotor section (listed as section 18/3 in the table of contents on page 3) gives you every part for the diesel powerplant.

RW 1504 HF, RW 1504 HK, RW 1504 HFK Parts Catalog – Bandage Standard Drum Assembly

The “Bandage standard” section (page 5) is where you start. You’ve got four scrapers per side, retaining washers, hex bolts – all with Verbus-Tensilock threads. The part numbers are printed right next to the exploded drawing. No guesswork. If you need a 630mm drum set, order 3-90202. If you’ve got the 850mm, it’s 3-90200. The catalog even separates the “Bandage separate” section (11/1) for the split-drum configuration found on some HFK models. That alone saves you a parts-counter argument.

Find the Correct Part Numbers for the Dieselmotor

The “Dieselmotor” group is section 18/3. You’ll see the motor fastening (19/1), exhaust silencer (20/1), air cleaner (20/2), and air intake (21/2). Each subassembly has its own exploded diagram with callouts. The part numbers are the same ones Rammax uses at the factory. Trying to order a replacement air cleaner? Look up the 3-58333 retaining washer or the 3-55946 hex bolt – the catalog gives you the exact DIN spec. Pair this with the Rammax RW 1504, RW 1504 HF, RW 1504 HFS 2001 Operators Manual – Factory Specs for maintenance intervals.

Does the Catalog Cover Hydraulic Motor and Vibrator Assemblies?

Yes. Sections 12 and 13 cover the “Hydroantriebe” – hydraulic motor and pieces. Section 14 handles the “Unwucht” (vibrator), and section 15 the “Unwuchtantrieb” (gear motor). The pump (section 21/1) is also there. If you’ve got a leak in the hydrostatic drive, the exploded view on section 12 shows every seal and O-ring. You won’t find that in a generic parts cross-reference. Aftermarket catalogs often skip the hydraulic motor detailed breakdowns because they don’t want to print 129 pages.

129 Pages of Exploded Views and OEM Part Numbers

That 129-page count isn’t fluff. Every page is used. The catalog includes sections like “Konsole-Cockpit” (23/1, 23/2, 23/3) for the cockpit console, “Senderhalteblech” (04) for the transmitter holding sheet, and “Empfänger” (05) for the receiver. Even the emergency stop bumper (24/1) and valve groups (24/2, 25, 26) are broken out. The OEM part numbers are directly from Rammax – no aftermarket substitutions in the margin notes. You order what Rammax designed, not what a third-party decided to substitute.

That page alone can save you an hour of cross-referencing.

Ventile: Valve Group Breakdown for RW 1504 HFK

Section 26 splits the valves into “Ventile, Einzelteile HF” (08 and 26/1) and standard valve groups. The HFK variant uses different manifold configurations; the catalog flags those sections with “HF” in the title. If you’re working on an RW 1504 HFK, you’ll want section 08 for the HF-specific valve components. The standard valves in section 24/2 and 25 cover the base models. Without this catalog, you’d be ordering a valve bank that doesn’t fit.

If you need operating procedures for other Rammax models, the Rammax RW 3000 S/SP/SPT Operators Manual – Factory OEM Documentation and Rammax RW 2900-HF 1996 Operators Manual – Factory OEM Specs for Trench Roller are also factory-printed.

Is this a genuine Rammax factory parts catalog?

Yes, printed by Rammax in Germany. Referenced serial number 1506704.

Does it include part numbers for all three models (HF, HK, HFK)?

Absolutely. The catalog covers the RW 1504 HF, HK, and HFK variants. Sections like “Ventile, Einzelteile HF” are marked specifically for HFK models, while the standard drum and engine sections apply to all three. The table of contents shows which sections belong to each subassembly. You’ll find the part numbers for the Dieselmotor mounting, the HD-hose routing, and even the receiver (Empfänger) – all with the exact OEM digits Rammax uses. No guessing which parts interchange across models.

Can I use this catalog to order parts from Rammax directly?

Yes. Every part number in this catalog is the same number Rammax’s parts department uses. Show them the 3-90206 scraper set or the 3-00422 drum, and they’ll ship it.

What if I need an operator’s manual instead of a parts catalog?

This is strictly a parts catalog – no operating instructions. The Automotive Industry Overview on Wikipedia explains why OEM documentation is separate. For operator procedures, get the Rammax RW 1504, RW 1504 HF, RW 1504 HFS 2001 Operators Manual – Factory Specs from our site.
