Extremely tight freewheel removal

[reohn2]

I`ve always used a similar technique you would use for getting tight car wheel nuts off-get the lever(Usually a half inch drive socket bar)horizontal after jamming the wheel in a corner like Mick does.
By standing on a bar only a foot long i can generate 200ftlb. That`s before putting any`bounce`onto it!
I did break a large half inch drive socket once many years ago trying to undo an Austin 1100 hub nut with the help of a scaffold tube.It turned out to be a LH thread!

I had a mate who had a Transit like mine with HD axles.He phoned me up utterly frustrated and on the brink of exhaustion with a punctured on a nearside tyre,complaining bitterly that he couldn't get the nuts off.
I simply replied,''LH thread''.
Two minutes later he phoned me back saying he'd got them of easily

FWIW Record/Irwin 135 cramps are a world away from the cheap stuff.
There's also the cheap ones with an Alu box section bar which IMO would fold under pressure.
All sash cramps aren't made alike IME.

sure;
135 series clamps are rated to 500kg and
136 series clamps are rated to 1000kg

I think you could easily exceed the load rating of either if you held a freewheel removing tool with one.

cheers

Going off your calcs yep that's a possibility.

Just as well we didn't know, then .

We have two, one a Record 135 and one a 136. It takes two of us to remove the freewheel from the tandem - I steady the wheel and OH provides the welly, but the freewheel comes off quite easily.

The clamps are brilliant pieces of kit. I paid about £5 each for them 40 years ago and they have been used regularly enough to have been well worth the initial investment. DIY, furniture making and repairs, as well as less orthodox uses such as cold setting the rear end of a bike.....they've always done the job for us. Mind you, they look flimsy compared to the ones I once saw in a piano repair workshop, wide enough to reach over the width of piano, with a T cross section and massive jaws!

That would be the LH rear. It's the only LH thread on the BMC/BL vehicles.

That`s right i remember it well, as i do the noise the socket made as it split!
