hydraulic press

[len]

has anyone experience of buying a hydraulic press for example a Sealey one , my use would be items such as wheel bearings and the dreaded bush replacements on my TR,
Thanks in advance

Dear Len,

The factory tool is a puller.

The triumph hub can easily be damaged by using a press, as many have found out.

The force needed to break the taper is often over 50 tonnes on a press.

There are drawings on this forum of a suitable puller.

There is a poor transition from the thread to taper, which is where the stub axle can break after an over-load, e.g. disassembly force on a press.

Additionally the drive flange is quite easily distorted when using a press, unless it is very carefully & substantially supported.

The bushes can be changed using large sockets & all-thread / long bolts.

Hope this helps.

P.S. I have a puller that works which you can borrow, but I'm in the midlands. (other people have to live there too!)

This thread might give you a lead to a close by puller:-

As jbuckl says it is easy to damage hubs using a press unless everything is correctly supported. The next thjng to say is that the cheaper 10 ton presses are of limited use. Ok for pressing most bearings in and out but useless for breaking tapers etc. I have 10 ton press, I do use it a lot but not as much as my old hydraulic puller. If I got another one I would spend a lot more on a 50 ton floor standing press. In conclusion if your interest is purely stag hubs and bushes don't bother and stick with pullers, bench vice and a range of large sockets. If its for wheel bearings and the like then it maybe worth it if you think you will be doing lots, just be aware it is not always as easy to support the hub perpendiculer to the press.

Would agree with the above replies. Recently I had to replace the seals on the diff drive shafts and I damaged the shaft flange on my 12Tonne press and still couldn't shift the things. Went to a local gearbox fettler who had a 50T press and he separated them and cleaned up the flanges for £15.00.
Ask at your local back street garage, they'll either do it or know someone who can.

Len,

If you are going to buy one for general use, I recommend the Sealey / Machine Mart 15 Tonne (not 10 Tonne) item as it is a lot 'beefier'.

As with any tool the max. performace should be taken with a pinch of Salt, i.e. if you want to be sure you can get 10T pressure the 15T item is the way to ensure that, especially with reliability.

I would not depend on any such machine for large hub bearings - My diff. output shaft flanges took 20T to push off and it's always worth going to a machine shop with the right kit and the knowledge to use it without distortion. A good back up which can avoid any damage is to cut most of the way through a bearing collar with a disc cutter (without going through) and then crack the rest with a chisel, sideways. Two grooves like this, 180 deg, apart can see a bearing collar simply fall off with no damage to the item it is fitted to.

Regards

Hi Len,

I have a floor standing one purchased from Machine mart - I think it is about 50 Tonnes but will check tonight; You're welcome to bring your parts up and use it.

Cheers
