Question about Skil 7 1/4" Magnesium "Mag 77" Wormdrive Saw With Twist Lock Model # SHD77M 72

1 Answer

Center bolt spins freely

Had to replace the outer flange/blade clamp on my Model 77 Skilsaw as it cracked from fatigue. I found the correct replacement part but now I find that the center bolt that hold the blade clamp on just spins freely. Easy fix or major repair?

There was probably a hole in the flange that you discarded that was used to put a pin/ nail/ bolt/ etc in from the body of the saw to hold that flange from turning while you did the nut up. Unless that hole is there you will have no way of holding the shaft to tighten the nut.

How do u remove the blade on a chop saw ls1013


Be sure the saw is switched off and unplugged. Use the Makita socket wrench on the side of the saw base if you still have it. If not make sure you use a socket or wrench that fits the bolts properly so you get them off and back on without damaging them. Lock the handle in the up position with the stopper pin. Loosen the hex bolt holding the center cover in place, this will let you raise the guard and center cover so you can get at the blade bolt. There is a button on the back side of the blade guard that locks the spindle. Push and hold the button in and turn the blade until it locks in place. Using the socket wrench, turn the blade bolt clockwise or in the same direction the blade turns while cutting to remove it, the outer flange and blade. Put the new blade on (check that the direction of the arrow on the blade is the same as on the guard), the outer flange and blade bolt. Use the spindle lock to get the bolt on tight. Return the center cover to it's original position and tighten it's hex bolt. Turn the blade by hand to make sure the spindle lock released then pull the stopper pin and make sure the blade guard works properly.

How do I replace the spring on the retractable blade guard on a model 77 worm drive skilsaw?


Bearings maybe......I'd also check the armature fan and see if it came loose. Either way it doesn't sound cheap!

How do you change the blade on a Husqvarna partner K750 concrete saw?


The blade bolt is 13mm,on the opposite side there is a hole in the belt guard to insert a 6mm pin to lock the front pulley, once locked undo the blade bolt counter clockwise, once removed, remove the outer clamping flange, you can then remove the blade, the standard arbour is 20mm, this can be changed if you wish to a 25.4mm, or a 22mm, depending on the arbour size of the blade you wish to fit, the arbour just pulls off the shaft with a suitable puller. Refit the the blade and outer flange, tighten the bolt securley.

Where is the blade lock button on a skilsaw 5150 2 1/8hp ???? i can't get the blade off and turning the saw bolt the same direction as it spins isn't working.


First, there is no blade lock button on the Skil model 5150. I called the Skil customer service and they emailed me the exact manual for this circular saw. The method I used to loosen a VERY TIGHT blade stud was: spray with WD-40, imbed the blade in scrap wood, set Skil wrench (usually found in back of foot under handle) on so it could be struck going in counter-clockwise direction. Use hammer to strike handle of wrench a couple of times. To replace blade, finger-tighten blade stud, then use wrench to tighten 1/8 turn or (45°).
