MULTI-COUPLER MAINTENANCE TIPS:

+ Familiarise yourself with the correct operation procedure
We recommend that you – and anyone operating your excavator using a Multi-Coupler - watch our operational video before useDo not force the Multi-Coupler onto attachment, as this may damage the Multi-Coupler or the excavator boom – follow the correct pick-up sequence.

 

+ Perform Visual Checks
Check the Multi-Coupler body and lifting eye for any wear, cracks or excessive movement outside of the acceptable range. Apply common sense and if in doubt – do not use!

 

+ Grease Regularly
Ensure you perform greasing regularly according to the guidelines in the Multi-Coupler Operations and Maintenance manual - Page 6.1 Manual

 

+ Clean grease nipples before greasing
This avoids getting foreign bodies (earth/sand) into the attachment and causing a rough paste to form. This roughness will grind against attachment parts with use and cause premature wear.

 

Multi-Coupler Troubleshooting

 Problem

 

 Possible Cause

 Solution

Difficulty picking up the Attachment with Multi-Coupler

 

Firstly, please take the time to watch our operational video.

 

Do not use excessive force to ram the Multi-Coupler onto an attachment -use pick-up sequence as instructed.

If you cannot pick up attachment using suggested sequencethen check the following possible causes:

 

Hydraulic Pressure is incorrect.

 


 
 

If the Multi-Coupler has been forced onto the attachment, the Safety Latch may have bent.

 
 

Check Multi-Coupler cast itself is not bent.

 

 

Correct Hydraulic Pressure should be between 2800–3000 PSI - see page 4.5 of Multi-Coupler manual.

 

 

Safety Latch is a cast part and so if bent, it needs to be replaced. We have replacement Safety Latches available.

 

If the Multi-Coupler is continuously used whilst the Safety Latch is bent, it can cause the Slide Hook to bend. Replacement Slide Hooks are available.

Attachment is difficult to release off the Multi-Coupler.

 

 

If the Multi-Coupler hasbeen forced onto the attachment, the Safety Latch may have bent.

 
 

Check Multi-Coupler cast itself is not bent.

 

Safety Latch is a cast part and so if bent, it needs to be replaced. We have replacement Safety Latches available.

 

If the Multi-Coupler is continuously used whilst the Safety Latch is bent, it can cause excessive wear and the Slide Hook to bend. Replacement Slide Hooks are available

Slide Creeping

In the event of the slide creeping check the cylinder pressure and check-valve.

Cylinder may be leaking

Check Valve may be faulty.

Test, repair or replace Cylinder as needed. Calibre Contracting Equipment have parts available.

HELITILT MAINTENANCE TIPS:

+ Familiarise yourself with the correct operation procedure
We recommend that you – and anyone operating your excavator using a HeliTilt Multi-Coupler - watch our operational video before useDo not force the Multi-Coupler onto attachment, as this may damage the Multi-Coupler or the excavator boom – follow the correct pick-up sequence.

 

+ Perform Visual Checks
Check the HeliTilt Multi-Coupler body and lifting eye for any wear, cracks or excessive movement outside of the acceptable range. Apply common sense and if in doubt – do not use!

 

+ Grease Regularly
Ensure you perform greasing regularly according to the guidelines in the HelitTilt and Multi-Coupler Operations and Maintenance manual - Page 6.1 Manual

 

+ Clean grease nipples before greasing
This avoids getting foreign bodies (earth/sand) into the attachment and causing a rough paste to form. This roughness will grind against attachment parts with use and cause premature wear.

 

+ Flush
Flush old oil out of your attachment on a regular basis and replace with new oil. Please refer to instructions in the HelitTilt and Multi-Coupler Operations and Maintenance manual - Page 6.1 Manual 

 

+ Pre-load - IMPORTANT!
You will get best performance and longevity from your PowerTilt if, after every 1000 hours (approx.), you check the shaft end play - Page 6.2 Manual 
If required pre-load HeliTilt as per instructions: 

Torque Wrench

With the lock ring removed, torque the end cap according to the End Cap Torque Specifications chart. HeliTilt Operations Manual - refer to page 10.7.

Tightening the end cap beyond ½ turn can cause the end cap to gall the shaft. If excessive end play still exists, the thrust washers should be replaced.

 

HeliTilt Troubleshooting

 Problem

 

 Possible Cause:

 Solution

Squealing Sound

Squealing sound may indicate a fault.

 

Faulty Relief Valve

Test, repair or replace Relief Valve as needed. Calibre Contracting Equipment has parts available.

 

HeliTilt is not holding position (Creeping /Relieving)

If this is occurring it means that oil is being transferred from one side of the piston to the other. To determine what is causing the HeliTilt to relieve, check the following possible causes:

Faulty Cross-Port Relief Valve.

 

Internal Seals may be leaking.

 

 

 

 

 

If it defective, you will need to replace the Relief Valve.

 

If these are defective, you will need to replace these and Calibre has Seal Kits available.

 

If you do replace the seals, we fully recommend that you also replace the Bearings while you are servicing your HeliTiltBearing Kits are available and prevent wear through reducing housing contact with the actuator.

HeliTilt swings in only one direction

There is a problem with the set-up of valves or the valve may be faulty.

Single Directional control valve is being used.

 

Cross-Port Relief Valve damaged.

 

Both lines connected to either both P1 or P2 ports of HeliTilt.

 

Replace with bi-directional control valve.

 

If it defective, you will need toreplace the Relief Valve.

 

Refer to the HeliTilt / Multi-Coupler Operational Manual for correct port connection location. Diagram on page 7.0 – ensure diagonally connected – one in P1 and one in P2.  

 

Spongy feel side to side.

 

Air in HeliTilt or Hydraulic circuit.

 

Diameter of tubing/hoses larger or longer than recommended.

Bleed air from circuit and check for cause.

 

Install new tubing/hoses with recommended diameters.

Install pilot operated check valve in lines as close as possible to HeliTilt.

Forward and backward movement of the shaft in the housing (shaft end play)

 

End-play may be too great – pre-load end cap.

 
 

Worn or missing thrust washers.

 

Tighten end cap according to End Cap Torque chart on Page 10.7 of the PowerTilt / Multi-Coupler Operations Manual.

 

Replace or install thrust washers if necessary – see tip on Pre-loading above. Refer toPage 6.2 of the PowerTilt / Multi-Coupler Operations Manual.

Won’t accept grease at fittings

 

Grease relief valve is not functioning, or has been replaced with a grease fitting or plug.

 

Clean or replace Relief Valves.

Oil Leaking

The location from which the oil is leaking will help determine the HeliTilt fault:

 

If oil is coming out of the Grease Relief Valve, Torque Foot & Idler, it is likely to be an issue with the Internal Seals.

 

 

If these are at fault, you will need to replace these and Calibre has Seal Kits available.

If you do replace the seals, we would recommend that you also replace the Bearings while you are servicing your HeliTilt. Bearing Kits are available and prevent wear through reducing housing contact with the actuator.

 

Problem with Base pick-up

 View Multi-Coupler Troubleshooting above.
