Simple hydraulic bearing puller from scrap vehicles

Простой гидравлический съёмник подшипников из подручных средствHello dear friends, DIY! In today’s article we take a closer look at how to make an interesting and useful homemade. Namely, consider how to make a bearing puller or similar, with any shaft. The couple often there are such situations when the repair machine tools or automobiles, there is such a need as the removal of the bearing from the shaft, and make it very difficult at times with a simple hammer can be very long to be busy, and still to no avail. So this hydraulic puller will facilitate this task, and most importantly, will accelerate it. Homemade will be collected from virtually junk, I mean, from what you can find at hand, the only thing you need is a simple hydraulic Jack.
This hydraulic bearing puller will need the following, namely:
– Simple hydraulic Jack
– Old Bicycle chain
– The thick metal “U” shaped profile
– Sheet thick metal
Bolts
– Nuts
– Washer
– A small segment of a thick-walled tube
– Metal corner
– A small segment of profile square tubes
– Metal cone
Enamel paint (optional)
Tools also need the following:
– Wrenches
Construction area
– Line
Welding machine with all necessary welding accessories
– Angle grinder with sanding and of course cutting discs
– Drill press or drill with drill bits
– Hammer
– Clamp or vise
Build a simple hydraulic bearing puller:
Let’s start with the basics, where will be located the Jack. In General, the design we have released a versatile and suitable for most simple hydraulic jacks. That is, if suddenly one day you come out of the Jack and acquiring other, new Jack, with high probability, the new Jack will come to our device. The author of the handmade as the basis decided to use a thick “U” shaped metal profile. Its width and length should be such that it could not be located to bulge beyond the Jack.

Plugs for added base stiffness and generally home-made with them will take on a more finished look. The stub should be cut out of sheet metal. This applied to the cap a metal plate and a marker to note the size of the awakening of the plugs, and do this twice. Then simply hold the plate and saw off the excess using a grinder and cutting disc.

Weld the stub to the metal “U” shaped profile, as shown below. First, fix the plugs a couple of spot welds and then carefully proverjaem the entire area of contact elements. Then after all proverili need to be sanded down all the welds, to our billet look monolithic part.

To do this, put on the base of the Jack and in places where the Jack will be nothing to interfere with, note the token space for the holes (the ends). These holes should be 3pc. Noting the location for the piercing of the holes, drilled them, and move on to the next step.

Bolts with a length of about 5 cm, not more. Sami bolts so that they do not fall prior to welding, fix the nuts as shown below, well and then with the internal side of the weld head bolts to the base.
Простой гидравлический съёмник подшипников из подручных средствПростой гидравлический съёмник подшипников из подручных средствПростой гидравлический съёмник подшипников из подручных средствGo to manufacture the clamp of the Jack. For this clip you need to pick up a pipe of suitable diameter. The author of the homemade cut out a ring of thick-walled pipes. To this clamp it was possible to compress and decompress, you must do the following. Namely, to make the saw cut a width of about 1 cm, this metal ring. Then on each end of the saw cut need to weld a couple of ears.

From this sheet sawn off the small rectangles, of a width not exceeding the width of the ring, and a length of about 2-3 cm Before you weld the lugs to the ring, in the center of each eyelet needs to be done through the holes under the bolts. After making a hole, weld the lugs to the ring, as is shown below.

Insert the lugs on the bolt and fix it with the nut, put a collar on your Jack and tighten the nuts. If the clamp after tightening the nut sits securely on the Jack, then everything is fine, and move on to the next step.
Простой гидравлический съёмник подшипников из подручных средствПростой гидравлический съёмник подшипников из подручных средствUntil we remove the clamp of the Jack. Set Jack on the ground in its working position. The clamp should be welded three bolts, these bolts are connected with bolts on the base using old Bicycle chain. This means that is necessary on the clamp to mark the space for the welding of bolts parallel to the bolts already welded to the base. And then weld bolts to the marked locations.

The circuit should be divided into three equal parts length of about 30-50 cm Length of chain depends on your needs (hereinafter will be more clear
what what).

For most of these claws will need a small cut square shaped tube and cut a metal bracket the same size. Cut corners and profile into three equal pieces no longer than 2 cm.

Once welded together workpieces, they make a through hole. In the end, we should get about the same billets, which are shown in the photo below.

Also still need to cut out from sheet metal of little triangles. These triangles it is necessary to weld in these photo places.
Простой гидравлический съёмник подшипников из подручных средствПростой гидравлический съёмник подшипников из подручных средствGo to manufacture of the stop, which will abut a subject that you want to remove the bearing. This emphasis will be done as a special attachment for a foot hydraulic Jack. It is necessary for this nozzle to select the right diameter pipe, cut from her cut was no longer than 3-4 cm, one of these parties need to stop, privaris metal round the plug.

This is the cone should be welded to the cylinder/nozzle that produced earlier, proverjaem strictly around the perimeter. Then zashlifovyvajut the welded joints and thereby give the form of a monolithic part.
Простой гидравлический съёмник подшипников из подручных средствПростой гидравлический съёмник подшипников из подручных средствPaint all components (optional). Now begin to collect all of the workpiece is made earlier together. Set the Jack to the ground on the Jack, put on the clamp. Next, put on the welded bolts of the chain as shown below and fix the chain nuts. The ends of the chain are put on the claws, also using bolts and nuts.
Простой гидравлический съёмник подшипников из подручных средствYou’re done! The end result is a simple and useful homemade. The results of the tests and methods of application can watch below:
