Large clutch release arm

[C4UKPOR]

Trying to remove the large clutch throw-out arm on the bottom of the gearbox. I've removed the smaller arm, retrurn spring etc and according to all the books, the larger arm should just pull off the shaft.
Mine is well and truly stuck, almost as if it's been pressed on.
Any suggestions gratefully received.

Mine also seemed to be pressed on. Maybe a gear puller setup would work, but I didn't have one. I did a transmission drop to check the clutch anyway. I had to remove the shaft from the transmission and spent a lot of time with a block of wood and hammer.

on some model, there is a pin holding it in place.
Otherwise, a puller, some heat, a hammer,

There is what looks like a pin that runs through the arm but is off centre from the shaft so does not appear to go through the shaft, plus the shafts has to rotate with the clutch action whilst the arm stays put therefore I assume the arm is fitted loose on the shaft if that makes any sense?
I'll try the torque release device(hammer) as suggested.
Thanks.

Remove the pin - it is holding the arm in place. How do I know? My '78 has one - they stopped doing this during the SC run. Only the Haynes manual actually shows this - Bentley does not.

Do not wrench on that arm until the pin is out.

Yup....you'll need to drive the pin out as it fits into a groove in the shaft (allows it to rotate on the shaft).

Another reason you should specify year and model of car, or add it to your signature.
The PET shows a pin on early omega spring arms, part 15, but does not use it on later models. My '86 transmission has no pin or hole for one.

well, if you have a pin, then it absolutely needs to come out first. And then the arm should slide off.

[C4UKPOR]

That makes sense. Can't always rely on bentleys.
Thanks for the help.

I try not to purposely destroy parts to remove them, but unfortunately, from my position lying on the ground), I had to destroy the clutch arm to remove the pin ('78 915). Seriously, was this German engineering at its best?

Sherwood - surprised to hear this, and sorry as well - that sucks. I will assume a PO took something to it prior to your work. For me, it was an excuse to purchase a really nice pin tool set and some (more) PB Blaster.

Made sure there was no pull on the lever, soaked it, and moved the arm back and forth in between punching the pin with the pin tool. slowly wormed its way out such that I could reuse it.

One tip I might give is to push the clutch lever back upwards, towards the trans, to be sure it is not binding the pin due to pulling it down. This is akin to the tightening of a stubborn bolt prior to attempting to loosen. Surprising how well that can work.
