OK so I just bought a used Sheng Shing (Sunhill) SDM-25 wide belt sander. I would like to go through the machine and replace all of the wearable parts to get this thing ready to operate efficiently and effectively.

Admittedly I haven’t hooked it up yet. It might be some time before I can get it plugged up, and I know that the best thing would be to hook it up and see how it runs to know what needs replaced. But it is a three phase machine and I have to wait and buy a phase converter which might be a month down the road.

So in the mean time I want to kind of go through the machine and replace all of the stuff that is typically needing to be replaced on these models of this age and make. That way when I get the phase converter I can plug it up and be (hopefully) ready to start sanding.

With that being said, here is what I know of when it comes to these machines and the parts that typically need replaced. I was thinking the tracking eyes, the diaphragm on the piston that controls the oscillation of the belt, and the air lines. What do you think? Anything else that I should possibly consider? The conveyer belt is in good shape. Where can I find parts to these Sheng Shing SDM-25’s? Are there any other mainstream suppliers of wide belt sanders that are identical to this machine? Such as Grizzly or Powermatic? Does anyone know where to find a manual? The main thing that I am concerned about is the oscillation of the sanding belt. I don’t know much if anything about wide belt sanders, however I have torn down and rebuilt other machines such as table saws and shapers. Any advice or answers to my questions would be great.

Any advice on where to get parts for this unit?

Does anyone know what models match this unit from the more mainstream manufactures such as Grizzly or Powermatic?

I have spent hours searching and can’t find anyone that sells parts for a Sheng Shing!

It’s made by Jun Shiau Machinery Company if that helps.

Check your Platen, mine has graphite attached to it.

Ok so my platen apparently has the graphite hanging off of it. Any suggestions on how to replace it? It looks to me like the only way to get the platen out is to remove the entire cast iron 3 drum assembly or whatever you would call it.

Mine just slides out. (It’s out about 8” in my picture.)

Have your say...
