How do you remove the pulley from a spindle, without destoying the pulley


Before you put the socket on the nut on top of the pulley, you need to take a piece of wood and place under the deck in such a manner as to stop the of the blade when you turn the nut. You can also use a set of vice grip locking pliers or a large c-clamp to stop blade rotation also by clamping to side of deck. Then you should have no difficulty removing the nut from the spindle releasing the pulley.

I need a diagram for the timing belt on my castel garden 20/122


pauly46_0.gifpauly46_1.gif hi there winger1886

pauly46 here


with 20/122 the blade timming must with one blade vertical and one blade horizontal
doesnt matter which one but as long as there is 90 degrees between blade as the rotate
in the picture the r/h blade rotates anticlockwise and the l/h blade rotates clockwise

the picture for belt / blade timming is straight forward - loosen tensioner rod and back it off completely , loosen 2 x bolts under the two toothed pulleys and remove the 2 belt guide/ stoppers from the l/h side - place both blades in the rqd position ( you may need someone to hold other blade in rqd position - fit the belt onto pulleys as in the diagram- continually check while fitting that timming has not moved from where you placed them ( they have to be 90 degrees from each other ) and then tighten the tensioner rod to hold position - rotate by hand recheck timming - if good loosly fit guide the 2 guide stoppers to l/h side and place 3.5 kg of tension at the middle point of the longest run of timmed belt ( belt should only deflect 10 mm with 3.5 kg of tension )
once tensioned tighten the 2 bolts under the toothed pulleys and tighten loc nut on adjuster
tighten the 2 stopper / guide nuts

in the picture the left hand blade is a l/h thread undo it right and tighten it left

the blade on the right is a normal thread left loose - righty -tighty

cheers hope it helps

Shaft turns while trying to remove blade on B&D MM875 elec. mower


Here's the scoop on the MM875: it has a plastic piece called a "blade insulator" (part # 241381-01) that "locks" the shaft to the blade, so that you can remove the nut by stopping or blocking the blade. If it has been damaged or stripped out, then stopping the blade won't do anything. However, the metal spacer directly under the nut IS still locked to the shaft (because of its shape), so you can use a pipe wrench or something to hold that in place and unscrew the nut. You might even be able to get someone in a home improvement store to do this for you. But you will still need to replace the insulator, which is only a few dollars.

Are the nuts holding on the blades reverse threaded?


If a blade, when viewed from above, rotates clockwise, it will have right-handed threads. This is because the shaft is turning to the right, and the resistance imparted on the blade will tend to tighten a right-handed fastener. If a blade rotates counter-clockwise it will have a left-handed fastener. I don't know this mower, but this is a universal thing.

Changing blades.To loosen the blades nut, which way does it turn?


hi. you dont say what make or model but I offer the following. if it's just a single bolt or nut holding the blade it will rely on a bellville type washer (dished ) or will be pegged either side of the nut or bolt, if the later try to drive the pegs down level with the mounting boss, now get a couple of friends to lift the whole deck so you can secure the nut or bolt in a vice (vise) and using both hands turn the blade itself the opposite way that you would turn the nut, this has never failed for me, if the blades counter rotate, one will be left hand thread the other right hand. bear in mind that a rotary blade spins at around 150-200 mph, every time you hit an obstruction (and you will) the blade will tighten particularly if secured with a belleville type washer. best of luck

Troy Built Ride-on, stalls when blade is engaged.


You may have a short in one of your safety switches. There is usually one on the seat that shuts it off if you try to get up and one on reverse if you try to back it up. I would look there to see if somehow they are grounding out

If you can get it where you can grab the blades, check and see if they float easy. You could have a seized bearing on one of your blades that is stalling out the motor as well.

Hope this helps
