How to replace a drill chuck?

During the operation of the drill occasionally jams or fails the chuck. Because of this it has to be disassembled, repaired or replaced with a new one. In this article we will discuss how to change the chuck on the drill.

Types of chucks

All drill chucks are interchangeable, so you can always replace one type with another. (it is only important that the threads in the bushing match). First you need to decide on the type of chucks:

• wrench (universal). This type cartridge consists of cams (petals) with a thread in the base, which are seated in an adjusting sleeve. It has a toothed jaw (round slot) where the wrench is inserted and the cams are tightened/released. Accordingly, the tool is clamped or released, depending on the direction of rotation of the wrench.

• quick disconnect. The socket of the quick-action chuck has no keyhole, but is adjusted by running in the thread of the petals. Turning it counterclockwise moves the jaws apart and clockwise brings them together. Adjustment is done manually, without additional tools.

Tools needed to change the screwdriver cartridge

The following tools are used to replace the chuck on the drill:

• Slotted screwdriver and Phillips screwdriver;
• lithol;
• Anti-rust agent like WD-40;
• vice;
• Pliers or hexagon socket;
• wrench (for keyhole chuck).

Chuck replacement

The procedure for replacing a universal type chuck is as follows:

• First, use a wrench to open the cams to create a hole into which a Phillips head screwdriver can fit. Then use a screwdriver to unscrew the fixing bolt. Note that the bolt has a left-hand thread, so unscrew it in a clockwise direction. If the bolt is corroded and does not come off, you must add a little WD-40 inside and wait 2-3 minutes. After that, the bolt should be easy to unscrew.

• The next step is to remove the chuck. To do this, place the drill on the edge of the table so that the cartridge hangs all the way out. Then unscrew the body of the drill and remove the cover. With one hand we press the pinion and the cooling carriage, and with the other we put the wrench into the gear engagement, and with a sharp downward movement “tear off” the fastening of the element. Then it can be easily unscrewed by hand in a counterclockwise direction.
• Before installing a new part, it is necessary to lubricate the shaft with lithol. Notice the thread pitch on the new chuck must be the same as on the old one. Otherwise it will not tighten on the shaft. Screw the new part out so that the blades come apart completely. After that, hand-tighten the cartridge onto the shaft that has already been lubricated with lithol. Replace the plastic body of the drill and tighten all the screws with a screwdriver or an electric screwdriver.
• The final step is to install the fastening screw. It should be lubricated with lithol, so that the next time it unscrews more easily. Screw in the bolt counterclockwise, but do not tighten it as far as it will go. Then we check the performance of the device by installing the drill, and start the drill in operation.

Changing the quick-action chuck

By design, a quick-action chuck is almost identical to the key chuck, the only difference is the absence of a key hole. How to remove the chuck from the drill, if it has a rapid-clamping design? The following sequential steps will help in this:

Particulars of fastening the bits

There are two main options for fixing chucks for a drill, an electric screwdriver. This is the threaded connection and installation on the cone. In the first case, there are metric or inch threads inside the clamping mechanism and on the shaft. A special screw with a left-hand thread is mounted on the axle to hold it firmly and prevent it from spontaneous unscrewing.

The latter uses a tapered shaft, also known as Morse taper. It has a characteristic shape, the same as the inner channel of the nozzle. Locking is performed by tight fit of one part into another. This variant is more often found in the clamping mechanisms of screwdrivers.

For ease of use, many manufacturers resort to special designation of the tool’s characteristics. The chuck mounting scheme can be identified by the marking. When you start with the drill and study the manual, you should pay attention to the type of the chuck and how it is connected. The following designations are found on modern equipment:

• Metric external thread. M, internal. MJ. The number after the letter, for example M9, indicates the connection diameter. It also determines the maximum size of the drill chuck, the minimum value of the shank.
• The presence of a UNF marker indicates the use of the inch system, which is typical of many foreign manufacturers. Therefore, you should carefully check the fitment of the new part before starting repair work.
• The tapered connection is marked with KM (Morse taper). The digits 0 to 7 following the letters indicate the chuck size.

Usually during the operation the wear and tear of the clamping mechanism itself, the seating. Then the drill can not be fixed firmly. When the equipment is working, it starts to wobble, it starts to throb. Chuck has to be changed in order to fix the problem.

Maintenance of the Bosch PSB 650RE Impact Drill

I decided to write a few articles on the simple disassembly of power tools and basic maintenance. I should warn you right away, I disassemble the tool without warranty or with warranty already expired, though frankly speaking I haven’t been addressed to warranty service yet. Let’s start this series of openings with a simple “green” impact drill BOSCH PSB 650RE. The drill is old, bought in Germany in 2007. The drill is made in Hungary. At one time decided that this drill is a full-fledged peorator, so the impact function at this time is almost absent, in the dissection will see why. But the overall impression of the drill is very positive, chuck runout are present, but they are very minimal, the chuck ROHM is very decent, jaws clamp perfectly and hold well. There were some problems with the reverse switch, but were cured by simple lubrication of the rubbing parts, otherwise no claims to this model. Currently, this drill is used as a regular drill, there is a peorator at home, so I no longer use it as a peorator 😉

So, let’s start the dissection. First let’s disconnect the additional handle and unscrew 7 screws, we will need a screwdriver with a “star” (torx T20), it is also possible to unscrew slotted screwdriver (places of screws are marked with red).

In order to undock a panel, it is necessary to pick up something thin and pass along the panel perimeter. After opening we discover the following picture. The electronic part (trigger) is connected to the motor with the quick-release terminals. Carefully disconnect them (you can not remember which wire is fastened to what, they have different length and connect the other way will not work). We pull out the motor and the mechanical part of the drill, having previously removed the reversing lever and the metal plate under the gearbox (marked green in the photo). Having examined the brushes, I decided not to take them out, they have a decent condition and they do not require replacement, so we carefully take out the stator unit and the switch of rotation (reverse) from the rotor axis. Brushes in this drill are changed by depressing the “tendrils” of the brush holder. ) Carefully unclamp the brush and spring and put the new ones in. The reversing unit from the stator as it is disconnected elementary, the unit turns clockwise by about 90 degrees and disconnects. After removing the reversing unit, let’s check the condition of the contact plates. In my case they are in good condition, no molten spots and development.

Let’s move on to the mechanics. Disconnect the rotor with the impeller from the gearbox by simply pulling it carefully out of the gearbox. Next we need to remove the plastic cover of the gearbox, by gently squeezing the two tabs and pulling the cover up. I must say the chuck was not taken off so I spent the further overhaul and cleaning in disassembled condition. The splines on the pinion which made the chuck were worn out, but since I was not going to recreate a good chuck, it was not recreated. If you want it can be replaced with a new one and the shock function will appear again. The grease was black or missing, but all bearings (needle) were in good condition and strangely enough German. Cleaned out all old grease and put new one in. Only found mineral-based, cast-based grease for friction units in gearboxes in my area. Ideally, it is better to lay the proprietary, which can be purchased at service centers BOSH, as an excuse I can say that I tried but decided to use what is available. The grease needs to be applied carefully, do not force it to the point where it comes out of all the cracks.

Carefully clean both panels from dust and other things, also carefully clean all other parts and then reassemble. Reassembly is done in the reverse order and won’t cause any difficulties. You might have some troubles with the locking system of the shaft and switching of the modes.

When closing the top panel, pay attention to the gaps and the absence of “bitten” wires. Fasten the screws, check everything rotates and there is no rattle. Switch it on and check it again. I think this scheme is suitable for most impact drills and with minor differences it can be used in other drills.

Thank you all! Let your tool serve you for a long time and bring only positive emotions! I would be glad if someone needed or found my review useful and will try to write a couple more in the near future.
