Types of bearing press tools

Post by Wookey » 03 Sep 2013, 00:34

I was considering buying a set of bearing removal tools as I've had much fun an games in the past managing without one. Looking online I see two different designs:
VS7023A: http://www.sealey.co.uk/PLPageBuilder.a ... ctid=16098" onclick="window.open(this.href);return false;
VS7026: http://www.sealey.co.uk/PLPageBuilder.a ... ctid=16474" onclick="window.open(this.href);return false;
(I'm not planning to pay those prices - you can get that for more like £100-£120 on ebay)

So the top one (VS7023A) has a set (20) of 5mm wall-thickness cylinders with separate caps. The bottom one (VS7026) has a number cylinders-with-solid-ends. I'm not sure how many, but it looks like 22 in the pic.

Is one of these better than the other? It looks like the 7023A set might be more versatile as you could use a couple of cyloinders inside each other to press on a wider area? But maybe in practice you always just use the biggest one that will fit, and they seem to have the same set of progressions in OD. I guess the cup-shaped once are perhaps a little easier to make sure the press stays square? The 7026 type is a bit cheaper, presumably because the depth is less (60 vs 94mm). For my purposes 60mm is fine.

Can anyone who has used both comment? It would be a bit of an investment so I'd like to get it right. Don't suppose anyone in Cambridge already has something like this and is happy to lend it out?

To be honest Wookey these kits are pretty useless in the real world as you need much more force to replace bearing on a teenage car in the UK due to corrosion. I know Mr. Haynes in his book of lies says you can use something like you link to for wheel bearings but actually he's talking cobblers.

The best investment I ever made was in a 10 ton bench press. You have to remove the hub or whatever you want to press from the car but that's a small price to pay for the guarantee it'll work.

They are short of mandrels and press-plates as they come from the factory but a selection of old wheel bearings and thick scrap steel plates do the trick nicely. I have that other most useful tool, a lathe, so if I need a specific mandrel I can whip one up easily.

The bench press has proved very useful and its scope goes way beyond just pressing bearings.

A proper hydraulic press does indeed look like a fine piece of kit, but it takes up quite a lot of shed. And surely you need something like that kit of cyclinders as well in order to have something the right size to press stuff out? I was thinking about getting a press as well, but was thinking more like: http://www.ebay.co.uk/itm/1-2-TON-500kg ... 2a1e5a52c4" onclick="window.open(this.href);return false; or http://www.ebay.co.uk/itm/RDGTOOLS-2-TO ... 565735588f" onclick="window.open(this.href);return false;
but it seems to me that you won;t get that much force witha rack and pinion like that? (less than the threads bar of the VS sealey kits?)

BTW how does this work: http://www.ebay.co.uk/itm/Small-Bench-P ... 7675.l2557" onclick="window.open(this.href);return false;
I see a machine base and a rack/pinion mechanism, but there seems tobe no top-plate/arm to push down with?

A large vice and an old socket set have usually worked for me. For the odd thing that has defeated me and need to be pressed I've just taken the assembly in question to my tamed garage. Bushes etc have usually been about a fiver a pop. Saves a lot of work, and the expense and storage of equipment I wouldn't otherwise use regularly.
