SOURCE: I need to know how much oil goes into a skilsaw worm drive resvr.

Haven't heard anything so I checked the Milwaukee worm drive saw and they recomment about 1/2 oz. Make sure you use an oil for a worm drive that is not foaming. Hope this helps. Also when checking oir level have the shoe set for max depth and on a flat surface remove the oil plug, when filling tip the saw on its side and fill, turn back over and allow excess oil to run out if overfilled.

Need manual sabre saw model 900.272510


That's a discontinued Craftsman model.
If you need replacement parts, you'll probably find that parts are difficult to find and way overpriced from Sears.
I'd check into used saber saws on CraigsList.

I needed a blade hub for a worm drive saw for a Craftsman saw and they wanted $46 and it would have to be ordered. (Its a flanged spacer that has the diamond shape that fits in the diamond knock-out in the blade.) The exact same part was used on several other brands including Milwaukee, Hitachi and Bosch. I bought a Bosch one from a local tool store for under $7.

Need to know how to get the blade off the miter saw to replace the blade


First, make sure it's unplugged.

On many saws the guard mechanism partially covers the bolt that holds the blade in place. Loosen and move the part out of the way as recommended by the manufacturer. On this saw you loosen a screw and then slide the mechanism up and towards the rear.

Press the spindle lock to lock the blade in place. Turn the bolt clockwise - opposite the normal direction - to loosen and remove it. Remove the outer blade washer and the blade. Leave the inner blade washer in place. Wipe a drop of oil on the surfaces of the blade washers that touch the blade.

Put the blade on the saw so that the teeth point down. Putting the blade on with the teeth facing in the other direction can result in serious injury. Put the outer blade washer in place. Turn the bolt counterclockwise until it is snug, plus another 1/8 to 1/4 turn. Replace the cover and you're finished.

My Craftsman 7&1/4 inch 12 amp Circular Saw(Model 315.108330) slips while cutting. The motor keeps spinning but the saw stops rotating. Can I Fix it?


Most circular 7-1/4 saws have a bolt and a compression washer that acts as a brake shoe that holds the blade secure but under dire circumstances will allow the blade to slip some rather than hold the motor shaft and allow burn out. The compression washer under your bolt has become worn and doesn't grip the blade securely. You can find a split washer that will fit under the blade and give you some more friction, or go to sears and order another compression washer for your saw.In the Sears Parts List found at: http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Saw-Parts/Model-32018780/0247/0744410/50035950/00001?blt=06&prst=&shdMod=

Blade continues to turn even with a screwdriver holding the blade


take the blade back off and make sure that you have the inner flange on correctly and see if there was a spacer between the bearing and inner flange.

Blade stops going once it hits the metal to be cut.


inside the motor/arbor section of the saw, there is a helical gear and worm drive on the motor. the front of the motor is supported by a bearing in the aluminum arbor section. sounds like most of the bearing balls are disintegrated and the worm disengages when a load is put on it but spins when there is no load. I would check and replace the front bearing.

My 3051 worm drive circular saw has he bade


Just for your information there are not many parts available for this model any longer.

With that said, it may be something rather simple. I get this type of problem all the time. Does the blade have the diamond punchout still in the blade or has it been punched out? Make sure that the the type of mount is the same as the hole for the blade. Another thing to check is to make sure the clamp washer is there under the blade. This is the part that will have a raised lip that goes through the hole in the blade just enough to center it. If that is missing you can replace it with a new one: part #143783-00 . If those 2 solutions do not work, it is your main drive gear. The worm is probably ok but the gear is probably shredded. This part is unavailable and renders your saw useless.
