Curry Care: Tip of the Month
Get Ready for spring with preventive maintenance – Service Trucks
Spring is coming and it’s the perfect time of year to do a complete preventive maintenance check of your compressor and crane. As your owners manual points out, there are daily, weekly, monthly and even hourly service checks that should be done to ensure long life and proper operation of your equipment. Here are just a few items on your compressor that should be checked routinely:
- Fluid levels
- Fittings and airlines
- Air intake valves
- Cooling fins on radiator
- Check valve
- Compressor valves
- Hydraulic filter
- Air filters
- Fittings and fasteners
- Electrical connections
- Air check valve
If you find yourself in need of any of these routine maintenance items, we have the parts that were built for your specific model truck and can ship them fast. Want us to do the service work for you? Give us a call at 800-345-2829
We can help to make sure that your truck is ready to work when you need it to.
Curry Care Tip of the Month – March 2015: Fighting Rust
Rust. Anything made of metal is susceptible. Once it starts it is very hard to stop. Here are some tips to help prevent it from starting:
Remove road grime and salt frequently. Remove any large deposits of dirt that get caked on. Those large deposits hold moisture which can penetrate the paint over a long period of time and get to the metal surface.
Touch Up Paint
Exposed bare metal is an invitation for rust. Inspect any areas that have exposed metal as a result of stone chips, scratches, or dents. Make sure to thoroughly clean the surface imperfection before applying the paint.
Keep Inside Areas Dry
Inside areas can be as vulnerable as those on the outside. Whether inside the cab or inside the body compartment, those areas will allow rust to start with long term exposure to moisture so keep it dry.
Curry Care Tip of the Month – January 2015: Two Types of Compressors
The two types of compressors that are used on mechanics and service trucks are: Reciprocating or Rotary Screw. In this two-part article we examine both types.
Uses a piston that moves inside a cylinder to compress the air. Typical reciprocating compressors have 2 or 4 cylinders and are available in single stage or two stage. A single-stage compressor is where air
is drawn into the cylinder, compressed, and then sent to the air tank. A two-stage compressor draws air into the first cylinder, compresses it, and then sends it to a second cylinder to be compressed again. A two-stage compressor allows for a higher p.s.i. (pounds per square inch).
• Relatively inexpensive
• Easy to maintain
• Suitable for high pressures
• High outlet temperature of compressed air
Draws air in, traps it between two rotors, and pushes it to the pressure side. These screws rotate side by side and have very little clearance between them. This is a much more precise design compared to a reciprocating design.
• Low noise level
• Large amount of air supply
• Relatively low end temperature of compressed air
• Purchase price is higher than piston-type compressors
• Maintenance very important due to the design
• Extended use is advised to avoid water condensate forming

Curry Care Tip of the Month – December 2014: Causes of Wire Rope Wear
Last month we covered the importance of inspecting your wire rope for wear. This month we will take a look at the causes of that wear and how to avoid it.
Here are some of the common causes of wire wear:
- Using the incorrect size, construction, or grade of wire rope. When your equipment is new, it is supplied with the correct wire rope. If you need to replace it, make sure you use the correct size, construction, and grade.
- Dragging the rope over obstacles.
- Improper lubrication.
- Operating over sheaves and drums of inadequate size.
- Overriding or cross winding on drums.
- Operating over sheaves and drums with improperly fitted grooves or broken flanges.
- Jumping off sheaves.
- Attaching fittings improperly.
- Promoting internal wear by allowing grit to penetrate between the strands.
- Subjecting it to severe or continuing overload. Note: Overload is not just a static load that is over the
- capacity of the rope but it is also severe acceleration of moving a load.
This subject is far too large to be covered in one article. To ensure that your wire rope is in properly working order, have it checked by an authorized crane inspector. When it is time for wire rope replacement, contact Central Hydraulics, a Curry Supply company, at 800-567-5127.
Curry Care Tip of the Month: Wire Rope Inspection
When well maintained and used properly, your wire rope (also known as steel cable) should last the life of your equipment. Periodic inspections are required to ensure long wire rope life. Here are some examples of what to look for:
- Severe kinking, crushing, cutting or fraying
- Presence of broken, cracked, fatigued, or corroded wires
- Evidence of heat damage
- Corroded, bent, cracked, or broken wires at end connections
- Dry or non-lubricated rope
If any of the above are present it is recommended to replace your wife rope immediately.
Wire rope failures can result in injuries, property damage, and lost production, as well as costly maintenance and repairs. Because there are many factors in determining deterioration, and many different types of equipment, all inspections of wire rope should be done by an authorized inspector.

KEEPING IT CLEAN WILL KEEP IT COOL
The one thing that will shorten the life of any vacuum pump is heat. If dirt or mud is packed on the pump, it will act like insulation and keep heat from escaping. Make sure fans are free from debris and are working properly on fan cooled pumps. Liquid cooled pumps need coolant from the engine to keep them cool so make sure the engine’s coolant system is working properly also.
