SUPPORT POUR POINTE KNOCK-ON KVERNELAND

Kverneland Knock-On Tip Holder 160 × 70 × 25 mm – Part No. CAM199750

The Knock-On CAM199750 Tip Holder is a part designed for soil-working equipment Kverneland using a compatible, state-of-the-art Knock-On quick-attach system. It connects the tine of the subsoiler or cultivator to the tip that works directly in the soil.

This stand has stated dimensions of 160 × 70 × 25 mm. Its total length is 160 mm. It must be installed carefully to ensure even support and prevent the development of stresses that could cause cracks.

It is strongly recommended that you Do not tighten screws and nuts with a pneumatic tool. An impact wrench can apply excessive or uneven torque and damage the wear part. Tightening must be done gradually using appropriate hand tools and in accordance with the manufacturer’s installation instructions.

Technical Specifications

Since the shape, hole patterns, center-to-center distances, and mounting method are not specified in the information provided, they must be compared with the disassembled mounting bracket before placing any order.

Important Assembly Instructions

Do not tighten screws and nuts with a pneumatic tool. Tightening with an impact wrench can damage the wear part and cause stress cracks.

This recommendation must be followed when installing the mounting bracket and related parts.

A pneumatic tool or an impact wrench can:

• applying too much torque ;
• produce repeated impacts ;
• tighten the fasteners unevenly ;
• create local tension ;
• deform the contact surfaces ;
• weaken the part ;
• to start a crack ;
• damage the threads ;
• make it more difficult to disassemble later.

It is best to start tightening the screws by hand, then gradually and evenly tighten them with an appropriate wrench. When the tightening torque is known, use a torque wrench.

What is the Knock-On mount used for ?

The tip is the first part to penetrate the ground. It must be held in a precise position to maintain a consistent working angle.

The CAM199750 bracket serves several purposes:

• receive the Knock-On tip ;
• ensure that it is securely attached to the tooth ;
• maintain the angle of penetration ;
• transfer the force to the tooth ;
• maintain the alignment of the wear part ;
• allow for quick replacement of the tip ;
• protect certain parts of the tooth ;
• withstand tensile forces ;
• be resistant to vibrations and impacts ;
• to make it easier to maintain the subsoiler.

A warped or heavily worn holder may prevent the tip from locking into place properly.

How the Knock-On System Works

The system Knock-On is designed to make it easier to install and replace the tips. The tip is positioned on a specially shaped holder and then secured by the mechanism designed for this technology.

The main advantage is the speed of repair. When the tip is worn out, it can be replaced without removing the entire holder, provided that the holder is still in good condition.

In particular, the system allows users to:

• quick replacement of the tips ;
• a reduction in downtime ;
• a reduction in operations involving the support hardware ;
• easier maintenance during construction ;
• rapid return of the machine to service ;
• Regular visual inspection of the parts.

The CAM199750 mount must be used with a Knock-On tip that has a compatible attachment profile. Not all Knock-On tips are automatically interchangeable.

Difference Between the Shank and the Tip

The base and the tip are two separate components.

The tip :

• works directly with the soil ;
• ensures penetration ;
• wears out gradually ;
• must be replaced regularly ;
• can be quickly installed on a Knock-On mounting system.

The support :

• remains attached to the tooth ;
• receives the tip ;
• transfers the force ;
• determines the working position ;
• must be replaced when it is worn, cracked, or warped.

A new tip cannot be held properly if the mount has significant play or a damaged gripping surface.

Dimensions of the CAM199750 Mount

The listed dimensions are:

• length: 160 mm ; ;
• width: 70 mm ; ;
• Specified overall height or thickness: 25 mm ; ;
• Confirmed total length: 160 mm.

These dimensions help distinguish this product from other items that look similar.

Total length: 160 mm

Length affects the position of the tip and the way force is transferred to the tooth.

A support that is too short or too long may:

• change the angle of penetration ;
• prevent the fasteners from aligning ;
• make contact with another part ;
• move the tip ;
• change the depth ;
• put stress on the tooth ;
• prevent locking ;
• cause uneven wear.

The length must be measured on the removed bracket in the same orientation as the new part.

70 mm wide

The stated width is 70 mm. It must correspond to:

• To the point ;
• On the support surface ;
• to clamps or fasteners ;
• to the shape of the tip ;
• Depending on the available space on the device.

A different width may prevent the holder from seating properly or cause a misalignment between the tip and the tooth.

Specified height of 25 mm

The third price announced is 25 mm. It corresponds to the height or overall dimensions specified as L × W × H.

This rating must be monitored, as it affects:

• the positioning of the bracket ;
• the engagement of the tip ;
• the contact surface ;
• compatibility with the tooth ;
• the effective length of the screws ;
• system alignment.

A heavily used part

The support works between the tip and the tine. It therefore bears a large portion of the forces generated during stubble cultivation.

He must bear:

• penetration efforts ;
• tensile loads ;
• impacts with rocks ;
• vibrations ;
• lateral forces ;
• changes in depth ;
• soil erosion ;
• mud ;
• plant residues ;
• temperature fluctuations ;
• the forces exerted by the tip.

A bracket that is not securely fastened or that is mounted on a dirty surface may shift and be subjected to localized stress.

Use on soil-working implements

The Knock-On tip holder can be used for various tasks performed with compatible Kverneland equipment:

• stubble plowing ;
• softening ;
• destruction of regrowth ;
• false sowing ;
• incorporation of residues ;
• soil preparation ;
• superficial cracking ;
• recovery after harvest ;
• a mixture of soil and stubble ;
• Preparation before sowing.

Compatibility must be verified based on the complete machine model and the installed tooth.

Effect of the Substrate on Penetration

The support determines the orientation of the tip relative to the ground. A correct angle makes it easier for the tine to penetrate the soil and helps maintain the depth.

A warped backing can cause:

• a tip that is too slanted ;
• insufficient penetration ;
• wear on only one side ;
• an increase in the pulling force ;
• an uneven depth ;
• poor cracking ;
• a difference in the amount of work between the teeth ;
• rapid wear of the tip.

When inspecting the machine, compare the orientation of the various pins.

Symptoms of a Worn-Out Support

It may be necessary to replace the CAM199750 if the bracket exhibits the following:

• a crack ;
• a deformation ;
• wear on the bearing surfaces ;
• a rounded Knock-On profile ;
• significant movement at the tip ;
• an oval-shaped mounting hole ;
• a recessed support surface ;
• a loose fastener ;
• a moving tip ;
• a tip that's hard to lock in place ;
• abnormal wear on one side ;
• a difference in angle compared to the other teeth ;
• a steady decline in peak performance ;
• signs of stress around the screws.

Even a small crack can spread rapidly due to vibrations and impacts.

Common Causes of Deterioration

The media may be damaged by:

• natural wear and tear ;
• a tip that has been used for too long ;
• a major impact ;
• excessive depth ;
• excessive speed on rocky terrain ;
• installation on a dirty surface ;
• misalignment ;
• a loose screw ;
• over-tightening ;
• the use of an impact wrench ;
• inappropriate fasteners ;
• a misshapen tooth ;
• an incompatible leading edge profile ;
• the presence of play ;
• incorrect positioning of the support.

The cause must be identified before installing the new part.

Why can an impact wrench cause cracks ?

An impact wrench doesn't just produce a steady rotation. It delivers rapid impacts to the fastener.

When the support or wear part is trapped between multiple surfaces, these impacts can cause:

• excessive compression ;
• a stress concentrated near the hole ;
• local deformation ;
• the beginning of a crack ;
• a screw extension ;
• damage to the threads ;
• a loss of control over the actual couple.

The crack may not be visible right away and may appear after a few hours of work.

Fasteners and contact surfaces

The fasteners must be compatible with the Kverneland assembly. Before reusing them, check the following:

• the diameter of the screws ;
• the thread pitch ;
• their length ;
• their strength class ;
• the condition of the heads ;
• the lack of stretching ;
• the condition of the nuts ;
• the washers ;
• the locking mechanism.

Support surfaces must be clean and level. A stone or a layer of soil wedged behind the support can cause uneven support and a concentration of stress.

Things to Check Before Ordering

Before selecting part number CAM199750, please check:

• the Kverneland brand ;
• the model of the subsoiler or cultivator ;
• the serial number ;
• the tooth reference number ;
• the inclusion of the Knock-On system ;
• the reference number of the old document ;
• 160 mm in length ;
• 70 mm wide ;
• a height of 25 mm ;
• the general shape ;
• the holes ;
• the center-to-center distances ;
• guidance ;
• the profile of the compatible tip ;
• fasteners.

A photograph of the disassembled mount, taken from the front and the side, makes it easier to compare.

Tooth Examination

The new abutment must be placed on a tooth in good condition.

Check:

• the flatness of the contact surface ;
• the absence of cracks ;
• the absence of deformation ;
• the holes ;
• threads ;
• areas of friction ;
• alignment ;
• welds ;
• the tooth's safety system.

A bent tooth can place constant stress on the shank and the tip.

Knock-On Tip Control

Before mounting a tip on the CAM199750 holder, check the following:

• its mounting profile ;
• its width ;
• the type of housing ;
• the lock status ;
• the direction of installation ;
• the absence of cracks ;
• the absence of compacted soil ;
• compatibility with the machine.

A poorly set point may be lost during the process.

Disassembly Tips

Before the procedure:

1. Park the tractor on a level surface.
2. Lower the tool all the way down.
3. Turn off the engine.
4. Remove the key.
5. Secure the cultivator with mechanical supports.
6. Clean the dirt around the assembly.
7. Remove the Knock-On tip.
8. Determine the orientation of the material.
9. Gradually loosen the fasteners using a hand tool.
10. Remove the bolts.
11. Remove the bracket.
12. Clean the tooth.
13. Check the contact surfaces.

Never work under a machine that is supported only by its hydraulic lift.

Installation of the CAM199750 Mount

General Procedure:

1. Compare the new part with the old bracket.
2. Check the dimensions: 160 × 70 × 25 mm.
3. Check the holes and center-to-center distances.
4. Clean the tooth.
5. Check the bolts.
6. Position the bracket the right way.
7. Tighten the screws by hand.
8. Check that the part is properly supported.
9. Tighten gradually and evenly.
10. Do not use an impact wrench.
11. Follow the recommended tightening torque.
12. Check for any abnormal stress.
13. Install the compatible Knock-On tip.
14. Check that it is locked.
15. Compare the alignment with the adjacent teeth.
16. Check the installation after the first few hours.

The Importance of Gradual Tightening

Gradual tightening allows the bracket to seat properly on the tooth. It prevents the bracket from pulling on one side only.

When there are multiple fasteners:

• Tighten all the screws before securing them ;
• Bring the pieces closer together gradually ;
• Alternate between the screws ;
• Check the support ;
• Finish tightening with a torque wrench if the torque value is known ;
• Use the locking mechanism provided.

The torque should not be calculated based solely on the screw's diameter. It also depends on the strength class and the design of the assembly.

Check-up After the First Few Hours

The parts that come into contact with the soil fall into place during the first few passes. After a few hours:

• Clean the assembly ;
• Check that it is tight ;
• Check for cracks ;
• control the game ;
• Check the tip ;
• Check that it is locked ;
• Compare the alignment ;
• Look for signs of movement.

If the mounting has shifted, you should determine the cause before simply tightening it.

Maintenance of the Knock-On System

To extend the product's lifespan:

• Replace the tips before they are completely worn out ;
• Clean the mounting profiles ;
• Keep an eye on the game ;
• Check the supports after an impact ;
• Check the fasteners ;
• Replace any damaged screws ;
• Keep the removal tool in good condition ;
• Do not solder the tip to the holder ;
• Do not enlarge the holes ;
• Follow the installation instructions ;
• Adjust your speed on rocky terrain.

Preparations Before the Stubble Plowing Season

Before a period of intensive work:

• Check all the tips ;
• Check the media ;
• Check the teeth ;
• Prepare the appropriate fasteners ;
• Keep a few extra pieces on hand ;
• Check the safety features ;
• Adjust the depth ;
• Check the rear roller ;
• Check for cracks ;
• Check that the machine is level.

A thorough inspection minimizes downtime during the season.
