1.1.1

General Introduction to the CLAAS REPAIR MANUAL The CLAAS REPAIR MANUAL is divided into main groups and subgroups.

Pages and illustrations are numbered consecutively throughout each main group. The first figure at the bottom of each page refers to the main group whereas the second figure following the point indicates the subgroup; the figure behind the second point indicates the page number. In each subgroup, the figures and pages are numbered consecutively, starting at 1.

Where differences between the machine types must be observed, this is indicated in headings. Where a service procedure applies to all machines covered by this book, the machine names are not specifically given.

When supplements are to be added, the subgroups are supplemented or exchanged. All supplements are inserted into the respective main group / subgroup and the table of contents is updated.

The symbols communicate brief messages when recurring service procedures are described. Their meaning is explained at the beginning of this manual.

The section “GENERAL REPAIR INSTRUCTIONS” at the beginning of this manual contains useful practical hints. Read and follow these fundamental instructions.

They are the basis for reliable service and durability of parts after repairs have been carried out.

The description of a particular service procedure can easily be found by checking the table of contents of the appropriate main group / subgroup.

General repair information GENERAL REPAIR INFORMATION

Removal:

Reason of damage

After loosening the axial clamping, loosen the taper ring fasteners with a sharp blow, using a block-ended tube.

Identify reason of damage, limit the case of damage and safeguard the machine.

Spare parts Use genuine CLAAS spare parts and corresponding CLAAS special tools.

Indicate the machine number of the round baler and also the respective serial numbers when ordering spare parts and in case of technical questions. This is necessary as otherwise, incorrect spare part deliveries may result.

Transmission When removing the transmission, first drain the oil and then remove the transmission. Separate parts which are firmly connected with each other by means of a soft metal-tip or plastic-tip hammer.

Tensioning the steel roller chains Find the centre point in the slack span between sprockets. With the tight span slightly under load, push in the centre point of the slack span with the thumb.

The chain tension is correct when its slack span deflects about 2% of the centre distance between shafts. Check chain tension more frequently when using new chains.

Example: For a distance between centres of shafts of 500 mm, the slack span of the chain should deflect about 10 mm.

Taper ring fasteners Taper ring fasteners provide a safe mechanical connection, even when transmitting high forces from the driving element on the shaft and vice versa, if they are properly prestressed.

Caution!

The inside diameter of the block-ended tube must be large enough to extend over the tapered ring.

Self-locking bolts (with microencapsulated adhesive) Replace self-locking bolts, e.g. Verbus-Plus / Imbus-Plus and similar types every time such bolts are removed. In exceptional cases, they may be reused up to three times. Always observe the specified tightening torque.

Always tighten self-locking bolts with microencapsulated adhesive rapidly to the specified tightening torque. When removing these bolts, quickly unscrew them completely. These self-locking bolts must not come into contact with sealing compound (e.g.

“Epple 33” or similar products).

In individual cases, bolts with liquid locking compound can be used instead of self-locking bolts only where these bolts can be heated up to approx. 200 °C for removing them. Ensure that the specified quality grade of bolts (8.8/10.9 or similar grades) is observed here as well.

Self-locking bolts with microencapsulated adhesive may be used only where operating temperatures will not exceed +90 °C max. These bolts can be subjected to full stress after 24 hours at +20 °C. To speed up the curing time, heating may be applied (e.g. to 15 minutes at +70 °C).

Installation:

Liquid locking compound

When installing taper ring fasteners, it is important that the shaft, hub, parallel key and the taper rings have been thoroughly cleaned, that semi-fluid lubricant of NLGI class 00 (e.g. Shell Retinax G or similar brands) is applied and that the components are tightened to the specified torque in the correct order of assembly.

(e.g. Delo-ML 187 / Loctite 242 or similar types)

Caution!

Use liquid locking compound only where specified by the manufacturer.

Correct application: Metal surfaces where liquid locking compound is to be applied must be absolutely free from grease. Use the “Aktivator” included in the workshop package for cleaning.

No solid grease must be used when assembling the parts.

298 332.0 - RHB ROLLANT 250 / 250 RC

1.3.1

General repair information Before applying the liquid locking compound, the metal surfaces where Aktivator has been applied must have dried. Especially in blind holes, no Aktivator (cleaning agent) residues are allowed.

When installing bolts, apply the liquid locking compound only to the internal thread (nut) if possible in small quantities (drops). In blind holes only wet approx. 1d (d = nominal diameter of bolt) at the thread bottom. The same applies to any extra-long female threads. When applying the liquid locking compound to the bolt or at the top end of a female thread, the liquid locking compound will spread over the entire thread length when screwing the bolt in. As a result, too much break-away torque is required to remove the bolt – Danger of breaking!

Threaded assemblies secured with liquid locking compound can be easily unscrewed by heating them up to approx. 200 °C.

Correct installation of lock collar bearings Lock collar bearings are tightened on the shaft by rotating the eccentric ring over the inside bearing ring.

Prior to installation, apply semi-fluid lubricant of NLGI class 00 (e.g. Shell Retinax G or similar brands) to the inside ring and the shaft to make bearing removal easier during future repairs.

Always fasten the eccentric ring moderately in the direction of rotation of the shaft and lock by means of a set screw. To remove the bearing, loosen the eccentric ring in opposite direction of rotation of the shaft.

Correct installation of adapter sleeve bearings Adapter sleeve bearings do not require a specially machined bearing seat. They may be mounted on any drawn or scalped shaft. This is an advantage because it allows the shaft to be axially moved as required to obtain correct alignment.

Always install adapter sleeve bearings according to the conical inside ring. Clean the taper lock adapter sleeve and the shaft and check that the sleeve nut runs easily so the taper lock adapter sleeve will not turn on the shaft when tightening.

Tightening the bearing: First tighten the sleeve nut to the point where the taper lock adapter sleeve has no more play and is under slight preload. Now tighten the nut by approx. 90° and continue turning until the next nearest slot fits the tab.

Secure sleeve nut with the tab.

Loosening the bearing: Bend up the tab which secures the sleeve nut and first back off the nut a few turns only (the thread must still fully grip). Loosen the taper lock adapter sleeve with a sharp blow, using a block-ended tube.

Ferrule fittings on hydraulic lines When pre-assembling the unit and for pre-assembled factory-delivered ferrule fittings, the following applies: installation is in the associated, well-oiled threaded joint with half a turn of the union nut beyond the point where resistance is felt.

Pre-assembly: 1. Cut off the tube at right angles. Do not use a pipe cutter because this will slant the tube wall, causing heavy inside and outside burrs. Slightly deburr the tube end on the inside and outside (do not chamfer!) and clean it. In case of tube bends, the straight tube end up to where the bending radius starts must be at least twice the height of the union nut.

2. Push the union nut and the ferrule on the tube.

3. Push the tube against the stop in the union and tighten union nut until the ferrule grips the tube (the tube must not rotate with the nut). This point can be felt because increase power is needed from here.

4. Tighten the union nut half a turn beyond the point where resistance is felt.

5. Check the cut made by the ferrule edge: A visible shoulder must fill the space before the ferrule front end. The ferrule may rotate, but axial displacement must not be possible.

Installation: Insert the pre-assembled tube into the well-oiled threaded joint, tighten the union nut up to the point where resistance is felt and then half a turn beyond this point.

1.3.2

RHB ROLLANT 250 / 250 RC - 298 332.0

General repair information Re-installation:

Re-installation:

Every time the ferrule fitting has been loosened, retighten the union nut without using increased force.

Every time the progressive ring fitting has been loosened, retighten the union nut until resistance is felt and then continue for half a turn beyond that point.

Ferrule fitting leaks: If a ferrule fitting leaks, first loosen the union nut until some oil escapes and then tighten it as specified.

Important: Back up the threaded joint with a wrench!

Progressive ring fitting leaks:

Progressive ring fittings on hydraulic lines When pre-assembling the unit and for pre-assembled factory-delivered progressive ring fittings, the following applies: installation is in the associated, well-oiled threaded joint with half a turn of the union nut beyond the point where resistance is clearly felt.

If a progressive ring fitting leaks, first loosen the union nut until some oil escapes and then tighten it as specified.

Caution!

Failure to observe the tightening torques reduces the nominal power and the service life of the fitting, resulting in leaks and in the tube slipping out.

Pre-assembly: 1. Cut off the tube at right angles. Do not use a pipe cutter because this will slant the tube wall, causing heavy inside and outside burrs. Slightly deburr the tube end on the inside and outside (do not chamfer!) and clean it. In case of tube bends, the straight tube end up to where the bending radius starts must be at least twice the height of the union nut.

2. Push the union nut and the progressive ring on the tube.

3. Push the tube against the stop in the union and tighten union nut until the progressive ring grips the tube (the tube must not rotate with the nut).

This point can be felt because increase power is needed from here.

Taper fittings on hydraulic lines Montage: Apply oil to the O-ring on the taper. Tighten the union nut a third of a turn beyond the point where resistance is felt.

Important: Back up the threaded joint with a wrench!

Caution!

Failure to observe the tightening torques reduces the nominal power and the service life of the fitting, resulting in leaks and in the tube slipping out.

4. Tighten the union nut half a turn beyond the point where resistance is felt.

5. Check the cut made by the progressive ring edge: A visible shoulder must fill the space before the progressive ring front end. The progressive ring may rotate, but axial displacement must not be possible.

Installation: Insert the pre-assembled tube into the well-oiled threaded joint, tighten the union nut up to the point where resistance is felt and then half a turn beyond this point.

Important: Back up the threaded joint with a wrench!

Welding Caution!

When carrying out electric welding work on the machine, proceed as follows: 1. Turn off the battery isolating switch!

2. Disconnect the connector to the display monitor.

3. Pull out the electrical plug-in modules in the central terminal compartment.

4. Always connect the earth clamp of the welder in the near vicinity of the area where the welding is being carried out.

1.3.3

General repair information Some advice for speedy and correct repair work: – Mark machine parts prior to disassembly to ensure their correct left-to-right positions and balance when reassembled.

– Fit expansion pins with the slot facing the side under load. When fitted with a quarter turn from this position, they will get loose, fall out or shear off.

– Replace cotter pins, locking wires, locking plates, tab washers and lock washers when carrying out repairs.

– Fit lubricated ball and slide bearings with high-quality grease.

– Align chain wheels and V-belt pulleys towards each other.

– Care for strict cleanliness when working on hydraulic systems.

– Never mix different oil types.

– Run the machine or operate machine assemblies at low speed after any repair.
