Can you tell me where you found your replacement bearings. I have the same spindle and the bearings I took out were peer 1641RLD and I can't find any on the internet
Bearings I got through my Gravely dealer for a ZT 2550 are Timken RA100RR. I had to heat the shafts with a propane torch to beak the spanner nut loose, even with an impact.
Guys-I sell bearings for a living. Given the harsh environment these bearings operate in, when you do replace those bearings, bet a quality sealed bearing. The deep groove ball bearings shown are shielded. they are not sealed bearings. Sealed bearings do a much better job at keeping contaminants out of the interior of the bearing.
Hey great video I knew they had to come apart, payed $75 for the first two last year now they want $$110-125. BS...I had the mall out trying to get it apart till I saw your vid. I made your rig twice, broke the first go. I still can’t get it, tried oil & heat with 3/4 impact hints the broke rig. Anyone else have trouble my grass is getting deep and I’ve got two bad spinals, just hate to spend $250
Freakin' amazing. I live in Florida, on five acres. We have sand, wild grass that shreds into 10 lb. string while mowing, moss, and sometimes a blue sky will turn black and soak us with raindrops the size of five gallon buckets (I exaggerate _a little,_ but), cold rain on a hot spindle can cause a vacuum so the bearings get wet. The mower is three years old, and it is an amazing machine, but nature works against the spindles. My neighbor has a huge lawn care business with big commercial mowers, and he can easily rebuild those spindles. I told him that my Gravely did not have spindles that I could rebuild. He cringed at the thought because he has to rebuild his once or twice a year (again he is commercial). He gave me the name of a company to look into, because they make spindles to keep water and debris from getting to the bearings (I don't remember the name). They are far more expensive than the normal "expensive" spindles, so I didn't bother with them for now. I have a few spanner wrenches that I'm going to try first. If none will fit, I will have my son in law take the spindle to his job, and let their mechanic build one of those homemade tools for me. I might do that at a later time, even if I have a spanner wrench that will fit. At this very moment in my life, *this video* is the greatest thing on the internet - lol.
can someone give me the spacing on the pin holes on the collar, I need to make a spanner wrench and the gravley XLT 48 is at my brother's home and he has no tools. thank you
Appreciate this video. I'm about to buy a Gravely ZT XL. Couple of questions: 1. Is this spindle cast aluminium or iron? 2. Did you just pack those bearings with standard grease like on a trailer? Thanks.
They are sealed bearings, so adding a zerk won't let the grease get to the balls... If you have it apart, and remove the inner seals, then it would work. Woody
@@woodyfking Woody-these things are shielded, not sealed. neither type are regreasable. I sell bearings for a living. You can only regrease open deep groove ball bearings. If you try to add an alemite fitting to this housing and inject grease, you'll be injecting grease into a cavity so that the pressure from the grease puts pressure on the shields which in turn will press against the bearing cage causing them to fail. Don't do it.
Vincent Lutz To remove the right spindle pulley on gravely zero turn mower I used a crowbar and a half inch nut. I placed the nut on the tip end of the crowbar in order to prevent damage to the pulley as I pushed downward on the crowbar. I pried it a few times @ position 6 then @ 12 then @3 then @9. By the time I went around 2 or 3 times it was off. Before I started the prying process I cleaned and sprayed the top of the top of the pulley with wd40 a few times. I hope this will help save you the difficulty some have experienced removing gravely pulleys.
I bought new ones for you guessed it about $150 and hated to do it. I was told they are not rebuild-able. Thanks for proving that comment wrong. I kept the old ones and will rebuild them and us as back ups. Thanks for posting.
This video was helpful, saved me some money and possibility of damaging the spindle. I made your tool and also made a second one to hold the pulley. I used a piece of 1/4 flat stock, drilled holes to the spacing of pulley holes and secured 1/4" bolts to the flat stock. I clamped the flat stock in a vise and set the pulley and spindle on the bolts. thanx
