Electric part repair tool

Same great tools, with only a new name. Genuine Ingersoll Rand replacement part. Designed for use with Ingersoll Rand power tool s.

The purpose of the Blade Pulley Tire is to keep the blade tracking correctly. Over time they will become brittle or stretched out. You then will have the problem of the blade coming off the pulleys or not tracking properly.

The tires simply stretch onto the pulleys. No tear down of any parts is needed. Please note shipping times may be longer than expected due to carrier delays. Shopping Cart. Submit Search.

If the brush really is chipped, taking a look at the armature for chips is a good idea while the tool is dismantled. Installing a new brush into a tool with a chipped or worn armature will probably just cause the new brush to be chipped as well. Checking an armature for chips and wear is explained below under Armature.

A burr can cause the same problems as other brush issues by preventing the brush from sliding into its brush holder correctly. Luckily, most carbon brush burrs only need to be filed down a little to be fixed. But a new burr might just form again if the worn armature that caused it isn't replaced. What to look for: Just look for the burr and file it down. Checking the armature for wear or chips is a good idea while inside the tool. For a "Brush Diagnosis" article--Click here.

An armature is the first major half of the motor assembly. An armature is a shaft -like assembly piece that spins as the tool operates. Armatures connect to the tool's brushes at one end of the armature called the commuator , which is the copper, segmented section on the left-hand end of the armature assembly pictured below. Commutators are important because they are the site of contact between the electrical current in the tool and the tool's motor assembly.

The commutator is located at one end of the armature shaft. Most armatures also include fans to remove dust from the tool and to keep it cool. Most aramtures pretty tough. A tool's brushes are much more likely to wear down before a tool's armature suffers heavy wearing or chipping, but overheating the tool will speed up armature wear a great deal.

Wear-Damage and Chipping: Commutators are segmented , with each segment divided by a groove. If a place between the grooves is chipped or worn down low, then the comutator will not be able to deliver consistent power to the rest of the armature and motor assembly.

Chipped or worn armatures commutators can chip brushes in turn, increase a brush's wear, or develop a burr on a carbon brush. If the armature is worn or damaged in this way, replacing carbon brushes will not fix the problem until the armature itself is replaced. A damaged armature must be replaced. What to look for: Always look for wear-damage and chipping on the armature's commutator, where it touches the brush.

Worn armatures will have low grooves where the commutator is separated into segments. Chipped armatures will will be missing segments of the commutator or have pieces of segments missing. Worn-down or damaged commutators cause the same kind of conduction problems as worn or damaged brushes and will show the same off-and-on service problems. Hint: If hitting or shaking a tool seems to help it turn on , it's probably a chip in the commutator or brush. When struck, the armature spins a little, lining up its gapped or chipped area s differently.

Heat Damage: Sometimes the armature suffers from overheating the most. The signs of a fried armature are very obvious. What to look for: Heat, sparks , and smoke. An armature meltdown will be pretty dramatic , and with good reason.

Enough head has to be collected in the motor assembly to melt the insulation surrounding the wires of the armature assembly. Discoloration and melted insulation will be plain as day on the armature assembly if it has indeed suffered a meltdown.

This means that the armature must be replaced for the tool to work again. The example picture below is of an overloaded field assembly, but the damage to an overloaded armature looks very similar. Sometimes the wire damage is more than just discoloration, as wires can break, chip, and become misshapen: Tips for preventing this kind of overheating can be found above in the Power Cords section of this article. Together , a field assembly and an armature assembly work together to create physical energy.

A field assembly is a ring -like piece that fits around the armature. The armature spins inside the field when the tool is in operation. There are two major reasons why a power tool field will fail. Broken Armature: The first reason a field assembly might fail is because of a broken or overheated armature.

What happens to one part of the motor assembly quickly affects the rest of the motor assembly. Overload: The second reason a power tool field might fail is from overload. Using a power tool for a work load that exceeds its specifications will cook a field assembly in a hurry. What to look for: A damaged field will act up a lot like a damaged armature.
