The Versatile 87740 Motor

87740 cOMPONENTS

The 87740 motor is the driving force behind some of the most popular pipe threaders in the industry, including the RIDGID 300 and 535. The Steel Dragon Tools version of the 87740 motor powers the Steel Dragon Tools 300 and 7090i. The 87740 motor is a versatile work horse and can be used across a variety of platforms thanks to interchangeable gearboxes. This motor is reliable, durable, and easy to service should the need ever arise.
IMG_2417

The 87740 motor has three main components; the field, the armature, and brushes.

 

The brushes are the item most likely to wear out first. The brushes are designed to make constant contact with the commutator of the armature. While the brushes are considered a wear item to be replaced on occasion, it is also important to inspect the armature and especially the commutator. After many years of use, the commutator can be worn away due to the constant contact with the motor brushes. This wear will result in a slight indentation in the commutator (fig. 1). New brushes will not be able to make solid, constant contact with the commutator, resulting in sparking, higher current draw, and loss of power. If the commutator shows this type of wear, it is easier and more cost effective to replace the entire armature.

 

The motor field is not a wear piece and will rarely need to be replaced unless it is damaged. Damage is most likely to occur during operation or maintenance. The field can be damaged by an electrical surge or if an internal wire is pinched.

 

Steel Dragon Tools offers replacement parts that will fit any 87740 model. Steel Dragon Tools is also a full-service repair shop specializing in reconditioning pipe threading machines. Steel Dragon Tools technicians have decades of experience and can quickly diagnose and repair most 87740 motors.

Obscure Fact About the 535

6

Steel Dragon Tools has over a decade of experience refurbishing pipe threading machines and accessories. The RIDGID® 535 is a prime candidate for reconditioning and can be found quite often in the Steel Dragon Tools shop. The 535 debuted on the market in 1957 and has been running in one form or another for over 50 years. Despite the years of experience, the technicians in the Steel Dragon Tools shop are always learning something new. In this case, the technicians pointed out that an 815A die head is not compatible on a 535 Version 1 machines that is equipped with a 340 Reamer.

 

This is a very specific issue that won’t affect most customers who use a 535 Version 1 machine. While the 815A die head is compatible with the 535, most customers will use the 811A die head. The 811A die head is much more common and is included with all reconditioned RIDGID® 535 packages offered by Steel Dragon Tools. For customers who have a 535 Version 1 machine and want to use an 815A die head, be sure to check which reamer in on the machine.
RD-RF-535-V1_01

 

Over the years, as the 535 machine changed from Version 1 to Version 2 to Version 3, the attachments changed slightly as well. The 811 die head became the 811A die head and allowed for automatic oiling. The 815A die head was later introduced with an automatic opening feature that opens the die head when threading is complete. The 340 reamer was updated slightly to become the 341 reamer.

SDT-815A_01

 

The 341 reamer is standard on later model 535 machines but will also fit the original 535 design. The difference between the 340 and 341 is nominal. The only thing that has changed over 50 years is the shape of the reamer arm. The 341 reamer has a shallow arm while the 340 reamer has a much more pronounced arm. It is the arm of the 340 reamer that will contact the 815A die head trigger, preventing the reamer from raising or lowering on the machine. This is only an issue when using an 815A die head on a RIDGID® 535 Version 1 machine that is equipped with a 340 reamer.

Comparing 4″ Pipe Threaders

SDT-1224-CRT_01

Steel Dragon Tools offers two models  of pipe threading machines that thread, cut and ream up to 4-inch pipe, rod, and bolts. The Steel Dragon Tools 1224 and the Steel Dragon Tools 6790 pipe threading machines both thread, cut, and ream a wide range of  black, galvanized, and plastic-coated pipe, as well as stainless steel, IMC, and heavy-wall conduit.  Both machines are equipped with a foot switch, reversible motor, and come with die heads and dies, and an optional stand.  The Steel Dragon Tools 6790 has a threading range of 1/2 in. to  4 in. The Steel Dragon Tools 1224 has a threading range of 1/4 in. to 4 in.

There are four major difference between the 1224 and the 6790:

 

1: The Steel Dragon Tools 1224 is compatible with universal RIDGID® brand dies, die heads, and jaw inserts.  RIDGID® or Steel Dragon Tools 711 and 714 die heads are interchangeable between the Steel Dragon Tools 1224 and the RIDGID® 1224 pipe threading machines. All universal dies will fit both die heads and machines. The Steel Dragon Tools 1224 comes with a Steel Dragon Tools 711 and Steel Dragon Tools 714 die head. The Steel Dragon Tools 6790 pipe threading machine also includes two die heads but the dies and die heads for the 6790 will only fit other compatible Steel Dragon Tools pipe threaders.

 
SDT-6790-CRT_01

2: The Steel Dragon Tools 1224 pipe threading machine is adjustable to thread both NPT (National Pipe Thread Tape) and  NPSM (National Pipe Straight Mechanical) threads.  The 6790 only threads NPT. The ability of the 1224 to thread both NPT and NPSM makes it an easy choice for electrical contractors who may have to do both.

 

3: The Steel Dragon Tools 6790 pipe threading machine has a two-speed transmission and 750-watt induction motor. The Steel Dragon Tools 1224 has a three-speed transmission and a 1,500-watt motor. The 1224 will handle 4-inch pipe threading much easier than the 6790 due to a larger motor motor and more-powerful transmission.

 

4: Price. The Steel Dragon Tools 1224 is considerably more expensive than the Steel Dragon Tools 6790. Both machines, however, cost significantly less than other machines built but name-brand competitors.

“A” is for Automatic – 811A and 815A

SDT-815A_01

Die heads for most Steel Dragon Tools and RIDGID® power pipe threading machines will either be automatic or non-automatic. Automatic refers the die head’s ability to automatically oil the pipe during the pipe threading process. These die heads will have a through-head oiling system. Automatic die heads will also have an “A” designation in their name like 811A or 815A.

 

The die head will connect to the pipe threading machine’s oil reservoir, if the machine has one (Steel Dragon Tools and RIDGID® 300 Power Drives do not have an oil reservoir and require a separate, manually operated oiler – like the Steel Dragon Tools 418 Oiler).

 

A pump in the pipe threading machine will push pipe threading oil to the die head where it will be distributed over the pipe during the pipe threading process. The automatic-style die head is now used across the industry. Non-automatic 811 and 815 die heads are typically not sold as new but can be found used or reconditioned. Steel Dragon Tools buys and reconditions used and broken pipe threading machines and accessories, including RIDGID® 811, 811A, 815, and 815A die heads.

811 vs 815 Die Head Debate

SDT-811A_01 A die head (or two) is a requirement for most industry-standard pipe threading machines. Using a Steel Dragon Tools 300, 300C, 7090-PRO, 7090i, 7090e, or a RIDGID® 300, 300A, 500A, 535, 535A, 800, 801, 802, or 1822 pipe threading machine will require a die head. Pipe threading professionals can choose between the 811- or the 815-style die head. (Most 811- and 815-style die heads are now being manufactured with automatic oiling operation, designated by the letter A — more on this next week.)

 

The main difference between the 811 and the 815 comes in operation. The 815 die head has a trigger mechanism that will automatically open the die head and stop the threading process once a certain number of threads have been cut. The 811 die head has a quick open lever that must be opened manually to stop the pipe threading process. Both die heads can be used to thread pipe and bolts, both thread in the right-hand direction, and both have the same threading capacities.

 

Seems like an easy choice, right? However, the 811 die head allows for a flexibility in threading that the 815 cannot accommodate. The 815 die head will always cut the same number of threads per pipe size before the pipe hits the trigger and stops the threading process. The 811 die head can thread further down the pipe should the need arise.

SDT-815A_01

 

The 811 die head will also be more reliable in the long run since there are no extra mechanical pieces to break or malfunction. Price-wise, the 815 will be slightly more expensive than the 811 but not by much.

 

Steel Dragon Tools manufactures an 811A and 815A die head that will fit most industry standard pipe threading machines including Steel Dragon Tools and RIDGID® machines. Steel Dragon Tools 811A and 815A die heads are offered with an automatic oiling feature for use on pipe threading machines that have a pipe threading oil reservoir.

Making Pipe Dies Last

SDT-477-Alloy_01Quality pipe threading dies should last a very long time if care is taken to keep them in good working order. Steel Dragon Tools manufacturers dies that are compatible with several brand-name die heads and pipe threading machines. Steel Dragon Tools dies are made from a composite alloy or high-speed steel and, under proper working conditions, should last a very long time.

 

To get the most out of a set of Steel Dragon Tools dies, here are some important tips to keep in mind when threading pipe. The following tips should be applied to powered and manual pipe threading machines.

 

  • Always use a high-quality pipe threading oil. High-quality pipe threading oil will reduce the friction between the dies and the pipe. The oil will also absorb heat during the threading process. Excess heat during the threading process can damage the dies and the pipe. Excess heat can cause metal chips to become welded to the dies. Metal chips in the die teeth will affect the consistency and shape of the threads.

 

  • Keep the dies clean. Clean dies make for clean threads. After threading pipe, use a stiff-bristle wire brush to clean any debris that may be stuck in the die teeth.

 

  • Install the dies properly into the die head. Dies that are not properly installed can result in damage to both the die teeth and the pipe. Double check to make sure the dies are properly installed before threading pipe.

SDT-477-Alloy_03

 

Following these steps will help ensure that the Steel Dragon Tools dies enjoy a long operating life and provide you with many perfectly threaded pipes.

Tips and Tricks for the 535

One of the common complaints from users of the Steel Dragon Tools Reconditioned RIDGID® 535 is that the chuck or the pipe wobbles, resulting in unusable threads.

 

If the machine is not threading properly, check the dies first. A good set of dies should last a very long time. Unless the die teeth are chipped or otherwise damaged, the dies should work without issue. Next, check the installation. Dies will fit into the die head only one way but should be installed securely and in the proper order. If the dies are installed properly, check the rear centering chuck. The rear centering chuck simply keeps the pipe centered in the machine. Do not over tighten the rear chuck. Only hand tighten the rear chuck, do not use tools.

 

The front chuck does most of the work when threading pipe. The front chuck should only be hand tightened. Do not use tools to tighten the front chucks.

 

To tighten front and rear chuck, spin chuck forcefully in a counter clockwise motion. The chuck will tighten around the pipe. Do this several times to ensure a snug fit. The sound the that the chuck makes will change as it tightens. Once the sound changes, the chuck is tight. A tightened chuck will give off a short, dull sound as the chuck has already tightened around the pipe.

 

Other Tips to Remember:

The guide marks on the die head are not exact. Always run a simple threading test before threading the actual work piece. Use a properly-sized fitting to test the threads. A properly threaded pipe will allow the fitting to turn one and a half to two turns before meeting any resistance. If the fitting continues to turn easily or does not turn at all, the die head settings will need to be adjusted.

 

Threads should only be cut to the width of the die head. Cutting threads too far down the pipe may result in unusable threads. Some dies are designed to cut tapered threads. Cutting beyond the width of the die head will result in straight threads instead of the desired tapered threads.
