Surface grinder help

[DSEL74]

Ok I have a problem, well a few actually but one in specific I want to ask about.

I bought a Power Surface grinder last year and am trying to get it running again. It is flat belt driven and the previous oven had started to modify it.

It has a interesting pulley set up and a weighted tension arm. There is one short belt for the auto feed. The longer one drives the head.

No issue there I think I have the belts butted out.

My problem is the long belt with no join is no longer attached to the grinder head spindle.

He has also machined grooves into that pulley to take rubber belts. I need to replace this with an original one but I can't see how to get it out?

At the back of the head is a single nut and a bearing race.

The front is a bit more elaborate and I don't have the spanners for it.

A few of you have rebuilt other machines is this similar and any tips on the way to tackle it???

Dale, while you're waiting for an answer, I think it might be a good opportunity to make a few spanners to help disassembly.

Is the diameter of the head pulley small enough to pass through the casting once you remove the bearing in the back of the head? If it wont then you will need to release it from the shaft to get it out.

And is this the tack weld you are referring to? Sure looks like one to me.

Not much room in there to try and see. But yes that is what I thought may be a weld. I only spotted it in the photo myself.

The pulley may fit through the hole in the back if the bearing was removed. The bearing would have been pressed in?


i don't know know if it should come out to the front or rear either.

Just realised I some how put this in the smithy rather than general section. If mids can shift it please.


Thanks to a C-spanner from the Swapmeet I got this loose so there is some hope yet.
