DYT4000 loose blade

One of the blades on my DYT4000 spins freely even though the nut is tight. I now cannot loosen the nut to get the blade off for examination. How can I stop the spindle from turning as I try to loosen the nut. I'm guessing I hit a root or something and chewed up the star center so need new blades. Any help appreciated

The blade does not tighten on the spindle and just spins freely. Even tightened down the center nut does not make a good connection to the blade.

There is a positioning "washer" that needs to be in place. If you don't line up the blade and position the washer it will not tighten. The blade will just spin around. Some even have a washer in front and in back. Be sure you have correct diameter of arbor that matches your blade too.

What will cause blades on J.Deere G100 mower to Freely turn by hand without causing Spindles or belt to turn even though Bolts are still tight and when installed Blade turned only if spindle turned

Do Ray:
If the blade engagement lever is in the disengaged position, the belt will be loose, allowing you to turn the blades by hand. If you place the blade engagement lever in the engaged position (with the motor off) it will be hard to turn the blades because of the tension on the belt. If the blades are still easy to turn with the blade engagement lever in the engaged position, you need to replace the blade drive belt!

How do i adjust a chainsaw

I like to loosen the blade quite loose, then hold the saw by the blade and tighten the blade retaining nuts. This puts the right amount of tension on the blade without making it too tight.

To remove the circular saw, which way do you turn the nut hold the blade on the saw?

For any saw blade or grinding wheel, the rule is this. Pushing against the points of the teeth should be the direction that tightens the nut. So you must loosen it in the same direction that the blade spins. For example, if your saw blade is on the right side of your saw, then the blade spins counterclockwise, and the wood pushes against blade clockwise - so you turn it counterclockwise to loosen it (which is in the same direction that the blade spins.). If the blade is on the left side of the saw, you loosen it clockwise. Good luck, Al K

Cannot loosen or tighten a loose impeller blade bolt on a ryobi leaf blower, rgbv3100

After taking the housing apart grab the opposite end of the impeller shaft with a good set of channel locks (my old standbys weren't sharp enough). Then while holding it tightly hit the old impeller blade with some sharp raps with a hammer, knocking the blade loose (hit the blade at a tangent, it loosens to the left like a regular nut and bolt). Once the impeller is loosened it can be unscrewed by hand and replaced.

I have a Superior brand slide mitre saw,quite new,but the centre nut for the blade is so tight wouldn't come loose,I used wd40,good vise grip,the nut quality is so soft,starting to wear out,even I griped...

This applies to the blade sitting to the left of the motor shaft. Try jamming a piece of 2x4 into the blade teeth, then using either a long-handle box-end wrench, or a 6-point socket fitted with a breaker bar to turn the nut by pushing down at the saw front. If the blade sits to the right of the motor shaft, then the reverse of the above should loosen the nut. However, the block of wood in the saw teeth will not help--you must freeze the blade with large 'vise-grips' at the rear of the blade and lift up on the wrench or socket. There should be a shaft lock to hold the motor shaft from turning. Good luck!

The blade on my B&D sawcat spins even with nut tightened. cold it be the blade is worn, but i put a new blade on and it doesnt spin as freely but still spins

Hole in the blade is greater than spindle on the saw, you did not put bush washer/reducer in, or if that bit is correct, you are puting holding nut wrong way in.

Do not use saw till you rectify the problem, switch off the saw, remove power cord from socket.

1. raise saw table up for maximum cut
2. retract slide-in protector to maximum
3. remove nut from spindle, following by blade (and bush if used)
4. check internalholding washer if it is correctly inserted.
5. orient correctly internal washer (it have notch or notches and will go freely only one way - check if that is the case)
6. insert blade, with reducing bush if required
7. if external washer is used put it in
8. screw in the holding nut, hand tighten and check mobility of the blade, tighten up about 1/8 to 1/4 turn with spanner, this should be sufficient to hold blade in place without any slipage. If slipage is still present, you are doing something wrong, you need then to supply me with exact model and I will describe exact part look and order in which they must go in.
9. connect to electrical outlet
10. short switch on and off
11. check blade for wandering and slipage, if none then make test cut
12. use as usual if 11 is correct

Hope this will solve your problem :-)

Hello. Most likely the nut which holds the blade tight has loosened enough that the motor spins the shaft but the blade just sits there and doesn't spin. This is an easy repair. You will need a large crescent wrench, or the properly sized open end wrench and a 2 foot long piece of 2x4 lumber. Use the lumber to "lock" the blade against the frame once you have the nut fairly tight. Then give it one more turn to be sure the nut doesn't loosen up on you again. It is best to do this job without turning the mower upside down as doing that will cause the oil to go into the air filter and then it will not start. If this is all basically greek to you ask a neighbor or a friend for help. It is really only a two minute job. J.

There is not a lock on this saw. If the blade is to tight to hold by hand you need to use an impact wrench. It will loosen the nut before the blade has time to start spinning.

Hello daobrien,
Not to worry, I think I can help you with your problem. You can try the WD-40, but first try the following. (Sounds like the repair shop wants you to come back.) First what I recommend is that you use your adjustable Vise Grip pliers and clamp it to the front of the blade. If there is a plastic shroud in the way, you may have to remove it temporarily. Doing this may give you enough leverage to loosen the nut. Apply the WD-40, then try to twist off the nut. The idea of using the pliers is allow you to not have hold the brake lock and give you the ability to apply enough torque to do the job. I have done this same thing when my framing saw nut was on to tight and it worked for me. Let me know if this is successful for you. If you would, please a positive feedback for me. I will very much appreciate it. Good luck! :o) Regards, NormanZ
