How to make a do-it-yourself reverse hammer to remove the hub
Content
Make sure that the inner tube has a larger section than the main pin of the tool: the do-it-yourself weight for the reverse hammer must always move freely along the rod.
Dirt, water, technical fluids get on the hubs, CV joints, bearings. The elements “stick” to the seat, and at the time of repair of the running vehicle, the first and most difficult task arises - how to dismantle the elements. Often, drivers build a reverse hammer to remove the hub with their own hands. A universal tool will later come in handy for removing ball bearings, bearings, nozzles.
Features of making a reverse hammer with your own hands
When it is not possible to knock out a “dried”, “adhered” part from its place with a hammer blow, a highly specialized reverse action hand tool is used. The design is simple: a do-it-yourself reverse hammer for removing bearings is easy to make on a workbench. There is suitable material for the puller in the garage.
Features of making a reverse hammer with your own hands
Find a pin (metal rod) up to half a meter long, with a diameter of 18-20 mm. Pick up a thick-walled pipe of a larger section with a palm length - this is the so-called weight, which slides freely along the pin. Attach a handle to the back of the rod. Install a fixing element from the other end of the rod: it can be a suction cup, a threaded nut, a hook.
Homemade reverse hammer for removing the hub
Your goal is to remove the hub with a reverse hammer. This means that you need to cause a retracting force of the tool - an impulse opposite to that created by an ordinary hammer. Start with a plan.
Device design
Think over the design of the mechanism, draw a diagram of the device. On the drawing, apply the dimensions of the reverse hammer for removing the grenade with your own hands.
Ready-made schemes can be found on the Internet. But, as a rule, you will make your own adjustments to them, because the reverse hammer for removing the hub with your own hands is not created from store spare parts: the parts are selected from the garage "good".
Required details
A do-it-yourself mechanical reverse hammer for removing bearings can even be made from anchors, and a square profile tube is used for the hubs.
Do-it-yourself mechanical reverse hammer
However, make a solid structure that will serve more than once, from used rear car racks, for example, from the VAZ 2108. They need:
- two metal pipes up to 12 cm long;
- old handle from a power tool;
- washer with an outer diameter of 60 mm and an inner diameter of 22 mm;
- lead.
You will need:
- grinder or hacksaw for metal;
- welding machine;
- gas-burner.
Manufacturing algorithm
Make a removable tool based on racks as follows:
- Step back from the stem 2 cm, cut the rack.
- Remove the cylinder and rod.
- Do the same with the second rack.
- Connect the two stems with the non-threaded ends. Weld the parts, clean, grind - the main core of the structure has turned out.
- On one side of the pin, weld the prepared washer, put on the handle, secure with a nut.
- Prepare an impact weight, put it on the rod, secure it with a washer so that it does not slip off.
Manufacturing algorithm
Do-it-yourself reverse hammer for removing bearings is ready. At the end opposite the handle, attach a detachable XNUMX- or XNUMX-arm attachment.
How to make a handle
The handle should fit comfortably in the palm of your left hand. It’s not worth messing around with manufacturing: remove the rubberized handle from the side of the power tool.
How to make a handle
If there is nothing suitable, cut off a piece of pipe that fits tightly on the pin, wrap it with electrical tape for convenience. use and anti-slip hand. It is necessary to fix the handle with a nut.
How to make a moving kettlebell
Take two pieces of pipes 12 cm long, one should enter the other with a gap. Weld a washer on one end. Fill the space between the parts with lead, heat the outer tube with a gas burner. The lead will melt. After cooling, the weight is ready.
Make sure that the inner tube has a larger section than the main pin of the tool: the do-it-yourself weight for the reverse hammer must always move freely along the rod.
