Recommend a bearing puller

[TrewithickFarm]

Hi all, need to small pulley on the belt drive on my reco sm270 mower.
My puller won’t go wide enough to pull it. It’s 160x90mm deep
Anyone recommend a puller that will do the job?
Thanks steve

I'd say a Sykes pickavant would do it. They are pretty robust and you can buy replacement arms etc separately

I'll second the sykes pickavent. I have one of these here.
18610000 - Hydraulic Thin Jaw Twin Leg Puller
I usually place a clamp over the jaws to stop them spreading/ breaking.
Replaced the cylinder a couple of years ago after about 30 years faultless service.

Sykes pickavant is about the best you can buy but you can get a set from spaldings very similiar in fact my spaldings ram may have actually lasted longer than my Sykes one. The biggest killer for the rams are when the pulley etc you are pulling is hot and transfers too much heat to ram

Don’t do what I did on our tarrup kv machine and reach over on the sides of where the belt sit, as there won’t be long before you hear bang and it’s then a three belt drive ( don’t ask how I did it or how much the replacement pulley was from kv, went for a taper lock and pulley still best end of 200.00.... ) try heating the pulley to expand it with gas and putting gentle pressure on it

Get a Kennedy set from Cromwell. A fraction of the price compared to pickavant but good quality stuff.

I had three cheap bolt type ones for years and they all died so bought a ten ton draper hydraulic one. How do people know when they're on their limit? The instructions say " do not use excessive force".

when you put a bit of small tube on the Tommy bar and bend it I'm fairly sure that's about it.

Fair enough. Wondered if it just can't go over a certain pressure. The old ones just creaked or bent so you know their limit!

Yes I can see that can be easily done. Will give it some heat.

SKF make the best pullers in the world. Nothing else comes close.
...also nothing else come close to price

Can you fabricate a strong fork to go other side of it? Heavy plate this side with a nut welded onto it, two legs from fork to the plate and wind bolt against shaft as tight as it will go then give the bolt head a proper wallop with sledge.

Went and rummaged around in my Late grandfathers tools and found these two beauties. Hopefully should do the job. big one is a Sykes pickavant

 

[Mur Huwcun]

That hydraulic one will do the job

if you pull that pulley with either of those two there's a very strong chance you'll pull a piece out of the pulley at the back where by then there's a good chance your pulley will be dickered depending on how much breaks away.
its cast so it wont take any pressure.

a pulley like that isn't simple to remove from the shaft, hopefully it wont be on that tight but id say there's a bigger chance it is than not.

you really need to be putting equal pressure all around, or as best as possible, like a plate behind it at the back of the pulley and then pull the plate and not the pulley, normally with two threaded bars 180dgs apart to a puller up front.
tbh id say there's more work in it than you want to do but when someone brings the likes of that to me its what i have to do a lot of the time.
id be inclined to shock it first with a copper hammer, drive it on further so to speak even tho its up against a shoulder, it ill help waken it up.

Maybe price a new pulley first and id imagine when you have that done you wont race into it too quick.

Well the pulley had an escape, neither of those pullers would fit. So went for another plan of attack.
managed to get to the culprit bearing. Just need to get the gear box off now.

 

[Munkul]

If you're a bodger and lucky, you'd be able to get that bearing out with blind hole bearing pullers. Then tap a new one in with a blunt chisel, being VERY careful to keep inner and outer even.

I would really like to check the gearbox for any other damage
