Resurected My Sears 917.353762

Those used the D176 mount number, so if you go to Oregon's chain website, the same bars were used on Poulan 3400 series. In other words, select the 3400 Poulan to pick the bar out.

Only 3/8" pitch is available for the nose sprocket, so you'll have to run 3/8 chain.

Your mileage may vary on the chain drive length count though, as the shaft to bolt center may be different than the Poulans, but I think they're the same.

Most of those later Ropers used a rim drive clutch drum, so I bet someone changed the rim from .325 to a .375 (3/8"), which is why you can run 3/8" pitch now. I probably could have told you from the pictures, if the dam things weren't upside down, a gravity defying saw LOL!

I was wrong, it is a .325 chain. I may have to change the drive sprocket. I found a spec drawing for the D176 mount, and it does look proper, but they are .375. It says otherwise use a D196 mount.

Is Oregon the only people that make bars and chains?

No, of course not.

A lot of different companies make bars & a few others make chains. But no other bar sources are easily found for your old Roper saw.

If you could find a roller nose bar, or hard nose tipped D176 mount bar, then you wouldn't need to change your chain or drive sprocket.
Post a "Want to Buy" ad here on AS, or watch evilBay for those specific bars I guess...

I have learned a bunch of info about this saw here. I bought it in the late 80's from a gal who had divorced and needed some cash. But I don't have the passion that you guys do to mess with the old saws. Give me an old truck and it's a different story!

Anyway, the bar is worn, but I'm going to try and "fix" it. The sides are not even, uneven pressure while cutting I assume. The groove width varies here and there. So I have the bar on my mill table and I will grind the edge sides square with the bar. Then I'll try to tighten the groove to .050" like you would on a 1911 Colt slide. I can get a chain, a .325/.050/74 tooth chain can be had. But I'm working on the one I have first.

If at that time, it doesn't cut well, and I'm not trying to make furniture here with it just a fairly straight cut, I'll post it here for sale and buy a new saw. Seems like there are several folks that like these things.

Nothing like a freshly divorced gal seller off her ex old mans stuff, I hope you got a great deal LOL!

Stuff a piece of 0,045" sheet metal between the grooves and flail it with a 3 pound hammer to close the rails, then grind or mill the edges square.
