I bought a older 16' slab saw and it needs to be cleaned throughly. Can i use engine degreaser to clean the old oil and compacted oil and dust from the inside without doing any damage to it? Got a brand new Star diamond blade with it for $550.00. I think that it was good buy. The only problem that I see is the clamp arms for the auto feed are stripped but I think I can get brass brazed on it then re-thread it. Thanks for any help.

I wouldn't think degreaser would hurt it any. I would cover the motor and not get anything in but otherwise...I'd use degreaser to clean my saw...

Degreaser should be fine. Just be sure to re-grease everything after you're done cleaning up. Covington recommends white lithium grease for the rods and threaded shafts.

I used some on mine last year --- remember it was laying on it's side in the yard ( pics) --- I also used the high pressure washer on it to get some of that caked on stuff off --- you don't really have to worry about greasing it up if you are going to use it right away -- the saw oil will coat EVERYTHING inside & out ;D as soon as you start using it ----- are the clamp arms made of brass to start with? -- if so you may be able to just mill them down a little and then recut the threads

I used garage floor cleaner, which I presume is degreaser to clean a saw and it worked great for the caked on stuff. I found it ate away at the paint a bit so you have to be careful. That's not an issue if you are going to repaint it in the end. I also used simple green cleaner to finish the job up. It didn't feel so toxic and did a fine job. Steve

Yes they are brass but both clamps arms are stripped pretty good. I don't know it there is enough left to rethread. I guess that all I can do is try that and if it doesn't work then try something else. It was suggested to take a nut of the right size and thread cut in half and braze the halfs to each arm. Can you braze steel to brass?

Does it look like this? This is from an 18" Highland Park saw. Yes you can braze brass abd steel but be careful to not distort the brass with too much heat. connrock

Yes it does. It is stripped where it clamps on the threaded rod.

Another fix would be to drill and ream the brass to accomidate a brass "bushing" .
Align the brass and clamp it in a vise so it is laying perfectly flat.
Drill and ream a hole to fit a brass "bushing" that is thick enough to re-tap the same size thread as the original clamp had.
The bushing can be brazed using a low temp silver solder without distorting the brass and the fix will be like brand new.
