Question: BLADE/BOLT W/ Star Washer

TVH

My saw is an older Rockwell model 315. I came w/ a 7/16" blade bolt w/ a star washer locked in a groove on the bolt. The old washer has broken off teeth and needs replaced, but the 7/16" blade bolt w/ washer is no longer available. There is a 5/16" bolt and washer still available. Has anyone else come up w/ this problem? I can use the old 7/16" bolt without the original
washer, if I could find a separate tooth type star washer in a 7/16" diameter, or one that could be drill out to 7/16". Any ideas on where such a washer might be available? It's been a fine saw and I hate to junk it for lack of a washer.
Thanks for any ideas. TVH

Reply: BLADE/BOLT W/ Star Washer

WJA

Hello TVH,

For the Rockwell model 315 the blade bolt is a part number 846781 and the part number for the washer is 801669. For the model 315-1 the blade bolt is part number 684398. The same washer is used on both models.

Hope this helps,
-WJA

Question: Change The Blade

Don Nesper

I have had this saw for many years. I do not have to change the blade very often at all. I am trying now and I cannot get the blade to tighten on the shaft. I believe there is a shaft lock button that I cannot find or is broken. Can you explain how to change the blade? What am I doing wrong? Thank you, I love this tool. I only have very limited use of my left hand/arm. This saw is well balanced making it usable by me.

I just read the responses below. I probably have the needed wrenches if I knew what they look like?

Question: Blade Bolt/Washer

Patrick

Which blade bolt/washer should I buy as replacement for my 315-1 Type 2? The original setup won't handle thin kerf blades. Thanks in advance for your help!

Question: Wrenhes

Bigstone

I have a 315-1, Type 2 and I need the open end wrench used to secure the shaft while the blade is being changed. Can you help?

Hi Bigstone,

The jackshaft wrench (part #48321) is unfortunately discontinued. You can still get the blade bolt wrench part #882456 if it is needed.

Hope this helps!

I still have my wrench which came with the saw. I can provide you with dimensions/drawing if you want to try to make one yourself. My 315-1 just broke last night--fell off the bench and cracked the depth adjust slide [ref. # 69, p/n 684587. So I'm looking for a used one for spare parts. It still runs great and there's nothing like it on the market anymore. Everything's made in China now...

I took an old circular saw blade and the width is the same as a 1 1/8" open end wrench for the jack shaft. I marked the wrench on the saw blade (marks a lot) and used my chop/abrasive saw to cut out a rough wrench shape and open the 1 1/8" opening to fit the jack shaft. Polished it up with a small (4 1/2" grinder) ... homemade part#48321... jack shaft wrench. I started with an old 1 1/8" wrench to grind it thin but that was too much work to fit in the space and the old circular saw blade was perfect in thickness and strength. AMERICAN MADE... nothing like the good ole' USA... to Hell with China Made.

I lost my wrench years ago, I've always been able to swap blades using the old "wedge the teeth into a black of wood" method. A normal wrench grabs the outside nut in this case.
ie: with the saw upside down, insert a the edge of a block of wood, like a 2X4 between two teeth to keep the blade from sinning while you apply torque to the outer nut.

Review: Porter Cable 315-1 - Last Of A K...

CyberDyneSystems

To the best of my knowledge, this is the last Porter Cable Circular direct drive saw that included the ability to easily grease the main bearing via a grease cap.
That in part is what has kept mine working as a front line portable saw in the contracting trades from 1985 until 2010 with no trips for service.
I have also always preferred the depth adjustment on these saws to the tilting type more commonly found.

New blades and grease kept mine going. It's final demise only occurred after a fall from a roof which has altered it's ability to cut a straight line. The saw still works, but the housing and bed are bent. Alas no replacement parts available.

If you find one working at a good price, it could last a lifetime.

Would you be willing to sell parts off your 315-1 to keep another good saw running?
I am in bad need of a good 7/16" blade bolt/tooth washer for my Rockwell 315-1, purchased in 1971 and still running fine.

Thanks, TVH
