Thread: ACE chisel morticer, a bit of help please.

What you have there is identical to a Wilson Morticer I have here. I think the problem component in your assortment of parts is the driven pulley, it contains a cone clutch mechanism which needs only to seperate by a milimetre or two to disengage, hence the lack of travel on the clutch lever.

I will take a couple of pictures of mine tomorrow for you to compare the setup in case you haven't already found a solution.

Thanks, any help would be good at this point.
I can't see how it can disengage with the two long keyways but maybe i need to dig a bit deeper............

There is another post on here containing a Wilson morticer like yours:

In your 4th an 6th pictures you have the driven pulley/cone clutch assembly in one piece, they are probably seized together as they meet at quite a shallow angle.

The driven pulley is free to rotate on the shaft and the cone clutch is keyed to the shaft inside it though free to slide along the shaft. The 2 should be pushed together by a stout square wire coil spring.

do you mean this?

If i am understanding you then i am not understanding you
I will try dismantling and see what's inside.
I had the bearing off and cleaned it but didn't see any other obvious dismantling.

What you are saying sort of doesn't makes sense (YET).

IF i am on the right page the outer wheel (that the belt runs on) spins independently of the inner sleeve (with the keyways that engage with the shaft) engaging with each other by means of the brass 'sleeve/bearing' at the front of the assemble????

This sounds like bizarre engineering and i think i have it wrong

Anyways, is it the bit in the photo above (driven pulley) at or is there something going on with the driven shaft inside the cast iron housing/body of the machine (behind the flange in the photo below)?

Looking forward to enlightenment...........

Yes I do mean that. That I believe is 2 cast iron parts, forming a cone clutch assembly, probably locked together with the addition of a little bit of rust. If you study your picture, the flat belt pulley has 2 flanges sticking up, follow the left hand one over its edge and there is a shoulder there almost the same diameter as the pulleys belt surface. This is the seperation point for the 2 pieces, if you look into the right hand end of the pulley, are you able to drift the left hand section out from there? Or you might get some luck just by running boiling water or some other method of heat around the outside of the pulley, it may just pop apart without the intervention of the 'gentle persuader'. It probably wont take too much force as the 2 surfaces form a cone.

Most Excellent, I will investigate and let you know .
Thank You

thanks sion,
came apart beautifully........

Question.....
This should be well greased?

thanks Sion,
I have a couple more questions......
I've greased it and put it back together but the throw-out arm won't separate the two parts.
Is it supposed to be dry or greased?
Is there supposed to be a spring (or anything else) inside the pulley to help separate the cone clutch?
The old thrust bearing was so worn out that it had worn down the lip that it sits on and the body of the bearing was scraping on the flange so i have put a spacer between the flange an the bearing (which increases the anount of throw and should help) but it still wont separate.

Any more advice?

Thanks for the link back to my thread - I was trying to decide exactly how familiar your machine looked to me.

I'm happy to take whatever pictures you need of my machine.

I'm not sure you have the travelling pulley system on the LHS on yours??

But whatever you need just ask - I can get a video of it working from the rear perspective if you like.

Cheers,
Paul

Hugh,
I've not been able to give the computer full attention recently, so apologies for a slow response to your query this time. Here's a photo of my machine in the disengaged position:

You can see the travel is minimal from the mark you can just see around the seperation point, perhaps only 3mm of travel in total. I have never had any of this apart so i can't confirm what is inside. But i would assume that the only spring needed is the large one on the outside to create the drive. The driven pulleys position would have to be held positively along the shaft as cone clutches can 'grip' together quite well, as you have already discovered. As for grease, i don't know, i would think it should be fairly dry, there is no lubrication point that i have spotted and where i have come across this type of clutch on winches, they have been intended to be dry.
