Hydraulic floor press?

[oldcorollas]

this is the unevennessness on the top bit
is also present on the bottom, ie the U-channels were welded while uneven.
simple to fix if i cbf.. will see if it affects things


48(?)mm ram (which has replaceable end that slides on, and held by o-ring)
bottom collar is.. 30-35mm? top collar is 15ish


overview...

[oldcorollas]

actually, the more i look at it.. the more i wanna fix it before using
might break out the welder this weekend...

[Supra967]

why bother? it's not going to affect anything. 20t will have those flanges flat and parallel in no time Looks good though, nice buy.

[oldcorollas]

have only loaded it up to abotu 10 ton so far.. frame seems ok there... should be enough.
going to make up either new bed, or thing to sit on top of stock bed to allow 150mm flange to pass through.. later maybe..

[petergoudie]

There is no doubt you get a lot for your money.

Before getting the welder out get a tape measure and 90 degree square. Check that the flange on the channel is not angled slightly and use the tape to compare left & right dimensions. Some of the dimensional (and angular) tolerances on Chinese steel is woefully bad.

Thanks for the info on the threaded collars. I might try to find out if they are available. As I said earlier, as far as I can ascertain all the dimensions on the rams are standardised (meaning they all copied the original U.S. Enerpac brand or whoever was the original manufacturer of high pressure hydraulics). If you were not aware, the rated force is at 10,000psi.

[oldcorollas]

yup, defintiely to check the channel is square

I can measure the collar and thread more accurately if you would like?

[oldcorollas]

picked up soem offcuts today..
100mm Uchannel, which is nearly twice as thick as the current press bed (which is 125 or 150?, but thinner steel).
going to make a hub pressing frame... basically just 4 bits of the Uchannel welded together to give 160-170mm space for axle/hub flange to pass though. (160 will be enough?? 170??)
will sit it on top of current bed.. should be ok

will check everything else is square at same time whikle the welder is out.

also got some 10mm thick right angle stuff.. to cut down on one side and use to get under bearing separator..
plus some various thicknesses (10-15? 20?) as spacers etc.

[oldcorollas]

new press bed.
100mm channel, 160-165mm square hole for hub flanges

bearing separator.. not sure how this will go yet
10mm thick right angle, (angle) ground to 6mm..

sometimes I wish i had a mill wait.. all the time...

[Supra967]

like it OC, should work a treat.

[oldcorollas]

worked awesome
little bit of flex geting the inner race off, but it did come off

now just need to create an arsenal of shapes to press with..
already used dumbell handle, synchro sleeve for K40 box, made 89mm plate out of a lintel(? above window thing) that was lying around..

need to get some various length rod to reduce pumping distance.. and various sizes of pipe for pressing seals and bearings..

[andrew_mx83]

Oc get yourself a cheap 3/4 socket set, will be majorly handy. Maybe visit a scrap steel joint for some more cheapies...

[dnegative]

Yeap, 3/4 socket set makes pretty good press tooling for wheel bearings and all sorts of shit

Can get a chapie for $150

[petergoudie]

1) Oldcorollas, thanks for the offer of more dimensional info but it's OK for the time being.
2) I just found in a Mazda 323 manual that 2.5 tonnes is required to push both wheel bearings at the same time onto the axle flange.
3) In regard to your bearing separator, they are usually held together by two long bolts to stop them flying apart under pressure.

[oldcorollas]

no worries, can check any time.

i haven't neeeded more than a couple of ton (indicated), but the dial is for 60mm ram. not sure if that is body or ram diameter
all i know is that "10" is enough to start crushing hardwood LOL

yup, i had a couple of G-clamps keeping them in position to stop them moving apart. thought I might need to clamp them to bed also, but seemed ok for now.
am wary of them bending or flying about.. they are only "standard" hot rolled steel, so not that strong either

[petergoudie]

The nominated ram diameter might be larger than the piston because the seal might be on its own flange and the bearing on the head end could be smaller than the tube bore so as to fit inside it. For instance, the ram piston might be 50mm and the cylinder bore 60mm.
