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: Blade Won

Stanley Snowden

I have model 315 Rockwell Porter Cable saw. All of sudden I can't get the blade to tighten down.

It seems to me that the bronze spacer(clutch) is worn too thin and needs to be replaced. This happens when a blade spins on the shaft because it was not properly tightened.

Question: Gear Lubricant

Ken Potter

I have owned a Rockwell 315 for 30 years. I am replacing the armature and gear for the third time now. Maybe because I use masonry abrasive blades sometimes. What is the best lubricant to use in the gear case?

Question: Porter Cable 315

Jim Hostetler

I cannot loosen the nut to change the blade on my Porter Cable 315 circular saw. I have changed blades on quite a few other circular saws, so I know the process. However in this case the hole shaft just spins even tho the blade is locked w/a piece of wood.

Hi Jim,

This is a fairly common problem with your model of saw. It has to do with the bronze washer and the sprung blade bolt wearing out. You will likely need to remove the blade bolt using an impact wrench. After the bolt is removed you will want to replace the bolt and the bronze washer. The blade bolt is part #846781 and the bronze washer is part #801669. Both are available from http://ereplacementparts.com.

Good luck with your repair!

You need the back wrench. A large flat wrench that fits the flat spots on the back washer. Your blade is spinning on the shaft and you can't hold the shaft still by jamming the blade. I have 2 315s and have used them since they came out.

Rockwell made a thin wrench that fits behind the blade to keep the blade from spinning for the spring type bolt/washers.
