Claas ROLLANT 66, ROLLANT 46 2002 Repair Manual

You are looking at a 97-page Claas ROLLANT 66, ROLLANT 46 2002 Repair Manual pulled straight from the Claas Service Department. Not a third-party reprint or a scanned copy with missing pages. This is the same binder that every Claas technician had on the shop bench in 2002. If you are maintaining a ROLLANT 66 or ROLLANT 46 round baler and want to keep it running without chasing phantom failures, this is the document that tells you exactly what to torque, what to adjust, and in what order.

Group Index: How the Manual is Organized

The manual is split into main groups, each covering a major system on the baler. Page numbering resets within each group, so the table of contents in the beginning is critical. The introduction on page 3 explains that pages are numbered by group first, then page within the group—for example, “3-12” is group 3, page 12. This sounds like a small detail until you are hunting for a specific adjustment while covered in chaff. Remember that.

Key to Symbols: What Those Icons Mean

Flip to page 4 and you will see the DIN 30600 symbols used throughout the manual. One symbol means “remove/dismantle,” another means “grease,” a third means “prevent damage to material.” These are not decorative. When you see the “prevent damage” icon, stop and read the note—it usually warns about crushing a seal or bending a pick-up tine. Ignoring symbols is how you end up with a parts order you did not want.

General Recommendations for Repairs – Read This First

The section at the front of the manual titled “General Recommendations for Repairs” contains practical hints from Claas service engineers. Do not skip it. It covers things like supporting the baler frame before removing heavy assemblies, which tools work best for specific fasteners, and how to prevent contamination when opening hydraulic lines. These are the kind of notes that save you a blown O-ring or a bent shaft.

Does This Manual Cover Both ROLLANT 66 and 46?

Yes. The cover says Claas ROLLANT 66 and Claas ROLLANT 46, and the introduction notes that differences between models are indicated by sub-titles or text headings. If a procedure applies to both machines, the manual does not repeat the model name—just the steps. Pay attention to headings that say “ROLLANT 66 only” or “ROLLANT 46 only.” They show up in the roller adjustment section and the pick-up drive section.

Roller and Pick-Up Adjustments: Factory Specs vs. Guesswork

The pick-up system on these balers uses a cam track and tine arms that wear unevenly if clearances are off. The manual lists the exact gap between the pick-up tines and the rotor—I would need the file open to give you the page, but it is in group 2, somewhere around page 15 of that group. You will also find the torque for the roller end bolts and the chain tensioning procedure. That is the kind of data you do not get from a generic ag repair website. Speaking of transmissions, the Manual Transmission section inside this manual covers the gearbox disassembly and shaft end float. Use the specified lock washer thickness or you will have play in the PTO drive. Another copy of the same external reference is available through the Manual Transmission article on Wikipedia if you want background theory, but for the actual bolt torque, stick with the OEM page.

Source Validity: Why OEM Beats Aftermarket Every Time

This is a factory binder from Claas OHG Service Department, published 2002. The introduction on page 3 states plainly that the manual is filed in a folder allowing supplemented pages—meaning this is the master document, not a condensed version. Aftermarket manuals often copy the torque table from the wrong model year or omit the “prevent damage” notes. If you have a ROLLANT 66 built mid-2002, the running changes are reflected here. Period.

7 Systems Covered – From Pick-Up to Discharge

The group index lists at least these major areas: pick-up and feeding, rotor and cutting system, bale chamber, tying and wrapping mechanism, discharge ramp, driveline and PTO, hydraulic and electric controls. Each one has its own set of adjustments, wear limits, and torque values. The bale chamber section, for example, includes the chain tension procedure for the bale starter rollers—something that gets mis-set constantly on used machines.

Is this manual specific to the 2002 model year?

Yes. It covers only the 2002 production run. Earlier or later revisions had different pick-up tine patterns.

Does the manual include electrical schematics for the tying system?

Electrical diagrams for the tying mechanism appear in the hydraulics/electrics group. That group includes the solenoid wiring, the twine arm microswitch adjustment, and the wire tie tension settings. If your baler drops a bale without tying, those pages are where you start. The wiring colors are coded to Claas harnesses—no generic wire labels. I have had to correct a dozen DIY repairs where someone swapped a ground and a power feed based on a third-party diagram. This manual gives you the OEM pinout, which is the only one that matters. You will also find the torque for the twine disc retaining bolts—12 N·m, by the way.

If you work on agricultural equipment in Texas or anywhere else in North America, you know that a baler down during harvest is a financial problem. This manual puts the factory procedures on your bench, not in a cloud service that times out when you have grease on your fingers. Access the Factory Manual and get the specs you need to stop guessing.
