Anyone got any spare round bar off cuts ?? Specifically 50-53mm OD if possible.

[tedmagnum]

Hey there.

Just bought myself a Hydraulic press...

What an AMAZING bit of kit. I can't believe I've been struggling with hammers and drifts on bearings for all these years.

Well, I'm doing a bearing job on a van which was such a b**tard job it inspired me to buy the press.. (Automotech 20T - £250 and EXACTLY the same as the £500 Sealy one).

Anyway, I got the massive old bearings out with a large socket but I need something to push the new one in as the socket is too small.

It's got a 55mm OD so I need something 52-53mm OD ideally. I'll have a go with 50 or 53 at a push.

I don't want to spend £50 on a short length of round bar just for this job.

I have a bearing press set but they're in-between sizes... TYPICAL !!


Cheers in advance.

I've got that exact set....

The 49.9 is a touch too small... With the amount of force I'll need to get this HUGE bearing in, I fear it will damage the bearing.

2" round bar is 50.8 and I think that's even a bit small..

Bloody Renault and their stupid French awkward sizes

Could you grind the edge of the old bearing a bit smaller then use that to press the new one in?
I used to have loads of old wheel bearing outer track ground down just for this, might need to use a spacer on the top.

Yup.. Considered this.. Still might do it.

It's just going to take a LONG time as the bearing is 55mm OD and 50mm long :9

I've changed a few rear wheel bearings on the old TVRs I drive; the bearing is 73mm dia and 45mm wide (from the Mk. 2 Granada!), usually use outer races from old bearings to get them most of the way in.
Pre-heating the hub carrier also helps.

Yeah... Done that a few times in the past..

These are REALLY tight though. I needed a press to get them out. If I use the old bearing I think that will get jammed in again. Unless I grind it right down which I might end up doing.

How I wish I hadn't sold my dads old Myford Super 7 lathe

If the old bearing has come out in one piece can you clamp it in a vice so the outer rotates then use a sanding disc to reduce the diameter? I've done this many times and if you get the sanding disc at the correct angle to spin the bearing slowly they grind down really nicely. Just make sure to wash the grit off before using it to prevent contaminating the new bearing.

Ivegot some 65mm round bar. How much of a slug would you want. Do you want it machining to size

if you are only going to use the old outer part of the bearing cut it with a thin disc, put it in a vice to close it to the size you require and weld it saves a lot of grinding

Ive done hundreds of bearings of varying sizes, and rarely have to use anything but the old one ground down enough to clear the hub and a bit of plate to bridge the top for the ram to push on, make sure you give the inside of the hub a manual whip round with some emery, clean off with brake cleaner etc and give the new bearing a slight smear of grease on the leading edge so it is less likely to bind and less likely to stick in should you have to change it again!

if it's a Reno Master type i have a new bearing in the shed for one and it's normally a 60 ton+ press for them and hub damage a lot of people just fit a new hub or another hub
it is a big bearing hub in oven bearing in freezer
best of luck

Alas, all I have is the outer race. It's the stock bearing so has a very thin sidewall..

haha don't say that..... It's a kangoo van and I hope I'm okay with my new 20T. The old one came out easy enough with it.

I totally agree... The new bearing was £20... If I knew I could of got the entire drum with the fixed bearing for only another £30, I would of done that

But, hey... What fun would that be

Sorry Ted, I didn't trigger with me that you were guy looking for advice on buying a press previously.I am surprised how quick your stuff came.

This is the way I have done it for years. I just whip through the old outer race with a 3mm cutting disc, and then use it to press the new bearing in. It should just pop out easily with a screwdriver. I have a box of split outer races in the garage that I have collected over the years. Try it - it really works, but its easier to remove if you put the thiner end in first as you have the fat end of the taper to get the lever under.

use some off cuts of flat bar 4-6mm thick. Lay the old bearing over them them scribe round it and cut/grind to fit the hole your pushing into and use your socket ontop of the flat bar to push it in nicely.

Or get Dave- shox dr to make you a bit up or what windy millar suggested

Yup..It all came NEXT day.

Automotech were FANTASTIC !! The press is great too.



Right guys. It's sorted now. I got some 52mm tube from a local workshop.

Bearing is in and working well.


Thankyou for all your help guys and for the offers of machined bar.

This is a great forum.
