CAM LOBE RE030747, RE030748 1999 Parts Catalog

You ever tear into a steerable cam lobe motor and find yourself staring at a pile of parts with no idea which bearing matches which seal? That scenario costs hours, sometimes a whole day, and a phone call to a parts counter that doesn’t know the difference between a 50-series and 60-series quill cover. This 34-page factory CAM LOBE RE030747, RE030748 Parts Catalog from 1999 is the antidote. I’ve spent 28 years in the trade, and I don’t trust aftermarket parts breakdowns for hydraulic motors—they transpose lines, miss revision codes, and leave you holding the wrong adapter shaft. This is the genuine OEM document, printed by the manufacturer, with all the original part numbers and grid locations.

What the Grids Cover – Section A, B, and L

The catalog uses a grid system—sections A, B, and L—to organize every component. Section A runs from A02 through A25. That group covers the steerable CAM LOBE motor, the fixed-mount motor, the serial number plate, and the entire alphabetical index. Section B (B01 to B07) handles the destroke pump, check valves, and brake components. Section L (L24 and L25) ties in additional steering yoke detail for both 50 and 60 series. Each grid cell contains exploded diagrams and part callouts. You don’t flip pages randomly; you go to the grid that matches the assembly you’re holding.

Steerable vs Fixed-Mount: Two Motor Families

Two distinct motor part numbers are covered: RE030747 (steerable) and RE030748 (fixed-mount). The difference is more than a bracket. The steerable version includes a steering arm, yoke assembly, and pivot components. The fixed-mount uses a flanged or splined shaft and a pentastar mount. Flip to the chapter labeled “STEERABLE COMPONENTS” (page 10 in the section index) and “FIXED-MOUNT COMPONENTS” (page 20). You’ll see separate illustrations for the carrier, pistons, and cam assembly. If you’re swapping a motor between a steerable and fixed mount application, this catalog lays out exactly which parts differ.

Why You Need the Serial Number Plate Decoded

Every CAM LOBE motor has a serial number plate on the inner cover. The catalog dedicates two full pages (5-2 and 5-3) to decoding that plate. You’ll see how to read the producing factory, displacement in cubic centimeters and cubic inches (800 cm³/49 in³, 1000 cm³/61 in³, etc.), mount type, shaft style, steering option, brake option, and destroker option. Motors prior to serial number 004400 have different coding. I’ve seen guys order a replacement quill bearing for a 60-series when they actually had a 50-series because they ignored the master machine code (248 vs 249). This catalog kills that guesswork.

That’s the kind of detail that separates a factory parts catalog from a generic online list.

3 Reasons to Stick with OEM Parts Catalogs

First, the part numbers are verified at the factory—every asterisk and revision note matches the production line. Second, the alphabetical index at the back lets you locate any component by name: from ADAPTER SHAFT to YOKE, STEERING (50 SERIES). Third, the torque specs (not in this catalog, but referenced in the companion service manual) are keyed to these exact part numbers. If you’re holding a Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide in your other hand, you’re set for fastener data. For hydraulic motors, you need this CAM LOBE catalog.

Using the Index to Find Parts Fast

The alphabetical index covers everything from “BEARING AND COVER, QUILL (50 SERIES)” to “VALVE, SHIFT.” Each entry directs you to the correct grid letter and number. For example, if you need the porting block, look under “P” and it points to the appropriate grid. No flipping through twenty pages trying to match a blurry diagram. The index is your roadmap. Combine it with the Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs if you’re working on multiple brands, but this CAM LOBE manual stands alone for these motors.

Understanding Camshaft Operation helps when diagnosing motor performance, but for parts identification you need the exploded views in this catalog. Get the wrong steering arm, and you’ll fight camber angle for days. Camber Angle setup is easier with the right parts numbers from this book.

One more tip: if your motor is a fixed-mount RE030748, check the “DESTROKE PUMP, CHECK VALVE AND BRAKE COMPONENTS” section (grid B). It covers the destroke pump, parking brake housing, and shift valve. Don’t skip the notes on earlier designs—some parts changed after serial number cuts. And if you need agricultural machinery specs, the Longagribusiness 410 DTC, 450, 450 DTC, 470 DTC, 530 DTC 2002 Parts Catalog covers those.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque values are in the service manual.

I have a RE030748 fixed-mount motor. Will this catalog cover the destroke pump?

Yes. The destroke pump, check valve, and brake components are covered in section starting on page 30 of the catalog. You’ll find exploded views with part numbers for the destroke pump assembly, including the shift valve and check valves. Make sure you reference the serial number plate to get the right revision. Some early motors have different part numbers for the destroke option. The catalog notes that motors prior to serial number 004400 may have variations. Cross-check the part number on the second line of the serial number plate.

Don’t waste shop time chasing wrong parts. Access the Factory Manual and get the exact OEM breakdown for your CAM LOBE motor. Your wallet—and your next job—will thank you.
