Tensioning the steel roller chains

The steel roller chains are correctly tensed when you

can push down the slack section with your thumb by

around 2% of its length (gear interaxial distance), while

the tense strand is under low stress. Verify the tension

on new chains more often.

Note!

All information regarding this subject-matter

can be found in the current Operator's manual

Example: interaxial distance 500 mm = thrust stroke

on the slack strand, around 10 mm.

116379

Taper ring fasteners

Conical ring assemblies represent a safe connection,

even if high forces are transferred from the drive com-

ponent to the shaft and vice-versa, as long as the

prestressing is correct.

During installation, it is important that the shaft, hub,

sunk keys and tapered rings be carefully cleaned

and then greased with gearbox fluid grease, NLGI-

class 00,suchas:CLAAS AGRIGREASE LC 00 / 000,

and then assembled in the correct order and tightened

to the recommended torque.

Dismantling:

After unlocking the axial stop, release the tapered ring

assembly with a driver tube, applying a firm and clean

strike.

85677

Gib head key joints

Prior to installation, the shaft, the hub and the keyway

must be cleaned so they are free of grease, paint and

rust.

When delivered as a spare part, the gib head key is in

its raw condition, it is therefore too high and would

stick out too far after arresting it. Consequently the gib

head key must be matched to the component in ques-

tion by milling or grinding of the bottom face so that it

will not stick out more than necessary after arresting,

but can still be dismounted perfectly using the CLAAS

special tools (straight or cranked key extractor). The

conical top face must not be machined. Treatment

with a file is not recommended.

Caution!

Sticking on tapered ring assemblies.

–Never mount parts using thick lubricating

grease.

Warning!

Damage to the taper ring fastener.

– The inside diameter of the block-ended

tube must be large enough to extend over

the tapered ring.

Caution!

Damage to the gib head key joint.

– Arrest the gib head key with a suitable

hammer that is not too heavy and with the

right touch.

Introduction

General repair instructions

81213

Never use force for arresting the gib head key in order

to avoid damage to the components (especially the

brake discs) and to enable loosening with the CLAAS

special tool.

14029

Self-locking bolts with micro-encapsulated

adhesive

Replace all self-locking bolts, e.g. Verbus-Plus and

Imbus-Plus, every time when removing them. In

exceptional cases, such bolts can be reused up to

three times.

Always tighten self-locking bolts with micro-encapsu-

lated glue quickly to the specified tightening torque.

Always observe the specified tightening torque.

When unscrewing self-locking bolts, unscrew them

quickly. Self-locking bolt must not get in contact with

sealing compound.

Self-locking bolts with micro-encapsulated glue can be

used only in locations where the operating tempera-

ture will not exceed +90°C.

The full load capacity of these bolts is achieved after

24 hours at +20°C. Full hardening can be accelerated

by heating-up, e.g. to 15 minutes at +70°C.

In specific cases, bolts with liquid locking compound

can be used instead of self-locking bolts only where

such threaded joints can be heated up to around

200 °C for slackening off. The specified bolt quality

grade, e.g. 8.8 or 10.9, must be observed here as well.

14031

Liquid locking compound

Use liquid locking compound only where this is speci-

fied by the manufacturer.

Proper application:

Metal joints intended for liquid locking compound use

must be absolutely free from grease. Clean such joints

with the "Activator" enclosed in the workshop package.

Before applying the liquid locking compound, the acti-

vator (cleaning agent) must have dried on the metal

surfaces. No more activator residues may be present,

especially in blind holes.

Apply the liquid locking compound of threaded joints

only to the inside thread of the nut drop by drop if pos-

sible. In blind holes, wet only around 1 d (d = rated Ø

of threaded pin) at the thread bottom. Proceed in the

same way with all excess-length screw threads. When

applying the liquid locking compound on the threaded

bolt or at the beginning of the screw thread, it will

spread over the entire thread length while screwing it

in and the breakaway torque is too high when slacken-

ing the bolt off later – danger of bolt tearing.

Introduction

General repair instructions

81213

Threaded joints secured with liquid locking compound

can be slackened off easily after heating them up to

around 200 °C.

14033

Lock collar bearing

Lock collar bearings are arrested on the shaft by twist-

ing the eccentric ring over the inside bearing race.

Before inserting, it is useful to apply some semi-fluid

lubricant of NLGI class 00, e.g.

CLAAS AGRIGREASE LC 00 / 000 to the inner race

and the shaft to enable easier dismounting of bearings

at a later date.

Always arrest the eccentric ring moderately indirection

of rotation of the shaft and lock it with a set screw. To

loosen the bearing, drive off the eccentric ring against

the sense of rotation of the shaft.

14035

Adapter sleeve bearing

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:

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.

Slackening off:

Slacken off the released sleeve nut for some turns only

for the time being. The thread must still be fully load-

bearing. Loosen the taper lock adapter sleeve with

a sharp blow, using a block-ended tube.

14037

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:

– Cut the tube at a right angle.

Do not use a tube cutter! This would cut the tube

wall at an angle and would cause a significant

amount of burr lines on both the interior and

exterior.

Introduction

General repair instructions

81213

– Lightly deburr the interior and exterior tube ends.

Do not chamfer!

– Clean the tube ends.

If the tube is angled, the straight edge of the tube lead-

ing up to the beginning of the curve's radius must be at

least twice as high as the box nut.

– Push the box nut and the cutting ring onto the

tube.

– Press the tube against the stop on the connection

sleeve and tighten the box nutuntil the cutting ring

surrounds the tube.

The tube must not turn during this process. This

may easily happen due to a significant increase in

force.

– Tighten the box nut a 1/2 turn beyond the resist-

ance point.

– Check the notch on the cutting edge.

A visible raised shoulder must fill the space in

front of the front surface of the cutting ring. The

cutting ring can turn, but may not shift axially.

Final assembly

– Fit the pre-assembled tube in the well-greased

threaded connector.

– Tighten the box nut until the resistance point is

felt.

– Tighten another 1/2 turn beyond this point.

Repetitive assembly

– After each time the cutting ring bolt connector is

loosened, the box nut must be re-tightened using

only the minimum amount of force necessary.

Unsealed cutting ring bolt connector

– If the connector is not sealed, it is necessary to

first loosen the box nut until a small amount of oil

flows out.

– Then re-tighten as directed. 14039

Progressive ring fittings on hydraulic lines

When pre-assembling the unit and for pre-assembled

factory-delivered profiled 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.

Pre-assembly

– Cut the tube at a right angle.

Do not use a tube cutter! This would cut the tube

wall at an angle and would cause a significant

amount of burr lines on both the interior and

exterior.

– Lightly deburr the interior and exterior tube ends.

Do not chamfer!

– Clean the tube ends.
