I did try to move it the other day and they seamed tight and greased them before trying it but the middle one didn't spin byIf you mean a noisy spindle, there should be grease fittings on them and they are easily rebuildable. Easy to tell a bad spindle, just grab each blade and wiggle it. If it wiggles, the bearings are shot and need replaced. Waiting can destroy the housings however. As with most used equipment, people don't trade in in or sell it because it's perfect. On the contrary. Usually, a piece of equipment, especially one that is older, will need work yo make it right.
I did grease all the pto parts before I ran it I will use the ziplock trick when storing it that's a good idea and check on the stubYou need to keep the PTO stub shaft CLEAN AND GREASED. Your local dealer will have a plastic PTO cover cover / guard that slips over the stub to keep it that way and same applies to the female coupler on ANY implement. They need to be clean inside and greased as well as the U joints on the PTO driveline. As a rule, I use a ziplock bag over the female end on all my implements to keep them clean and out of the weather. Easy on, easy off. All my hydraulic connections are always dust and dirt capped when not in use (tractor and implements) as well.
I will check it out don't remember a nut but I'll look and not sure on the dust shields as to where theyIf there is a nut on top of the spindle, they are not pressed on, If there is a nut, the nut secures the assembly and there will be a spacer inside that pre loads the bearings (how mine are on my mower deck). Even if they are pressed on, I suggest removing the inner dust shields on them so the grease can get in them when you grease the spindles.
I used to replace bearings every year until I figured out that removing the inner dust shields actually allows the bearings to get sufficient grease Have not replaced a bearing since.
You can probably get them cheaper at a bearing place like Motion Industries. Each bearing will have a catalog number etched into the body and you and bearing place can cross that number to various manufacturers. Bearings have been standardized for decades.
Pressed on isn't an issue here, I have a hydraulic arbor press.
Ok I'll check them out and see I appreciate the helpYep, 9 is the pre load spacer and 1 is the preload nut. Part 5 is the expansion (tapered bush) that secures the assembly together. That is a 'Browning' bushing as it's called. and the drive pulley (6) is keyed to the shaft.
The upper and lower bearings (8) may have dust shields on both sides and if the do, remove the inner facing dust shield with a sharp edged knife or pointed pick and toss it. That will allow grease from part 21 to get into the bearings and prolong the life of them Your spindles are very similar to mine actually.
