How to take out bearings out of housing on castlegarden 17,5/102 deck

debris --rust--release failure

could be the blade is loose or already came off. the belt may be loose.

By loose blade I assume you mean that it can be moved up and down at the tip of the blade. It is most unlikely that the central nut has come loose, but check anyway. If this nut is tight and the shaft is loose in the bearing this means the bearing has worn out. Remove the deck from the machine. Photograph the run of the belt as this has to be removed. Also the direction of the grease nipple. Remove pulley from loose spindle. Turn deck on its edge or mount on two saw horses or similar so you can get to top and bottom of spindle bolts. Remove cutting blade. Remove spindle housing and clean area so no rubbish gets caught when reassembling. Otherwise spindle may be set different and mower will leave a line of differing cut. Take spindle to vise and remove any retaining nuts or circlips from shaft and clean as clean as new. Apply light oil or CRC etc to help move bearing along shaft. Open vise wider that outside of bearing, usually 44 to 50mm [1 3/4" to 2"] and refit nut on thread. Check nut is always spaced free of top bearing. With cushion of hardwood or nylon tap the shaft to move it down with lower bearing coming out of spindle housing. To remove top bearing from housing, turn housing up other way and use a wooden shaft such as a broom handle to tap bearing free of housing. Clean out grease and replace when reassembling. Do not reuse other bearing. They are cheap and likely to fail shortly anyway. These bearings usually have no seals on inside.

Remove deck and place on two boxes or saw horses so that you can access both top and bottom of bolts holding spindle housing. Remove drive pulley from spindle. Remove cutting blade. Remove four bolts holding spindle housing to deck frame, noting which way grease nipple is pointing. Take spindle housing off and scrub deck frame clean of rust etc and also clean housing with wire brush. To remove bearings, look for retainers such as nuts or circlips. Remove these and ensure that the shaft is clean so bearing can be slid off. Apply CRC or light oil to assist bearing removal. Use a vise and set jaws wide enough that the bearing outside can fit between. This is usually 45 to 50mm. [1 3/4" to 2"] Place a hard wood block [or something that will not bruise the thread such as solid nylon] and screw nut well on to thread but make sure there is space for movement between nut and bearing. Firmly tap spindle end. Shaft should go down into top bearing and bottom bearing should start to emerge between vice jaws. Make sure that there is always space between nut and bearing before knocking end of shaft again. To knock top bearing out, place it on bottom over vise jaws and take a length of wood such as a section of broom handle and knock it out. Normally there should be no seals on the inside of these spindle bearings as they are greased from a grease gun thru the grease nipple.

To replace spindle bearings: Remove deck and either rest on two saw horses or similar mounts, or stand on its side and fix to make safe and secure. Photograph the belt layout and also the grease nipple so you can easily refit.The object is to access the top and bottom of the spindle. Remove cutting blade. Remove pulley on top side. I reccomend that you also remove the spindle housing from the deck. You can remove bearings while still fitted but it is not so easy. Clean the shaft and remove any circlips or retaining nuts from spindle. Take the unit and clean shaft as clean as new. Use emery paper if necessary. Use light oil or CRC to lube the shaft to slide bearings off. Do not hold shaft in vise as this will cause deformation of the shaft surface and jam the bearing. Place lower side of housing on vise which should be open slightly more than bearing outer diameter. Take hardwood or industrial nylon [to protect the thread from bruising,] after refitting nut on shaft thread, and ensuring there is space between nut and bearing, tap down firmly with hammer. The shaft will move more easily after the initial freeing up. When it moves easily remove nut and tap down with wood between hammer and thread end. To remove the top bearing use a wooden shaft, a broom handle is ideal. The replacement bearings should have no seals on the inside. Remove if necessary. Make sure to scrub clean both housing end and deck where the housing fits. Any rubbish there will cause lines in the mowing as it can tilt the blades. The thickness of paper can mean 3mm at the end of the blades!

Remove deck belt from blade pulleys and Tri to spin blades by hand. If they don't spin freely, you probably need new spindle bearings but if you do need a new spindle I would replace the whole spindle housing... Just make sure the one (s) you buy has housing, spindle, bearings, nut and washer.

Are your blades upside down? Mower deck level?Proper air pressure all 4 tires?Correct blades for the diameter of cut? Deck bent? Deck hangers bent?

I assume you are referring to the deck bearings. The easiest way to replace the blade drive bearings is to remove the deck from the mower. You can then easily remove the blades, clean the deck and be able to easily get to the bolts holding the bearings and pulleys in place. This is normally a straightforward repair and can be accomplished with common hand tools. You will need to purchase the parts from the dealer who sells the mower. Replace all 3 set of bearings. On a 3 year old mower ask yourself why the bearings failed. Are you washing under the deck when the bearings housings are hot? That will cause premature failure. Are you greasing the bearings regularly?

first take the blade off the spindle, then take the belt off the top, now there should be a nut on the top of the spindle you will have to remove that nut once you get that one off the pully will come off the spindle, now you will have to remove the bolts holding the spindle housing to the deck, put the spindle housing in a vise, put the nut back on the top of the spindle so that if you mass the threads with the hammer you are going to hit it with them you can fix them with the nut by taking it off again... now you have the nut on the top of the spindle and its in the vise, now hit the spindle to knock the bearing out of the bottum once you push the bearing out, you can remove the spindle out the bottum, now flip the housing over and take a punch and push the other bearing out if you are going to replace the bearings when replacing the spindle, i would reconend it... if you need anything else just xomment and ill repost...
good luck
