Spring pin removal - cutting wheel ?

[mopetta]

I tried to remove the spring pins on my A7. One side worked well, but the other side still does not move.

- I heated up the casing and cooled down the pin
- Used an extractor (large enough tube with big washer) to tear the pin out
- Used a hammer and a drift punch

but still there - any other ideas that might do the job ?
or is it now time for the cutting wheel ?

thanks, Oliver

Yes.

The pin very likely is worn and has grooves in it.
You may find jacking up the casing very slightly and using a big punch with a Big hammer shifts it.

I had a similar problem on a Big Seven.

I thought I would make a mess with a cutting wheel, and decided to try a hacksaw first.

Thinking it would be hardened, and not cuttable, but ..... worth a try.

To my surprise, the hacksaw worked.

I've found when fitting them, a pair of stilsons on the spring and twisting the spring a little can take the tension off the pin. Might be worth having a go like that whilst still giving the pin a good clout...

Today, I managed to cut the pin out and finally remove the axle from the car. But now, the next problem... My pinion has at least three damaged tooth. Are the new CWP set's available all the same quality ?

Hi,
New CWP sets are available with a slightly improved teeth design.

Looks like mine! David Cochrane is the man.
