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

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.

Thanks man saved me about 300$ rebuilding 3 spindles.

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.

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.

I was looking for someone who took them apart, I’m fixing to do it to mine, thanks buddy.

The threads are standard right hand. So turn it counter clockwise to remove.

David, I'm glad to hear it worked for you! Best of luck!

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.

Thanks! Same exact spindle.

Found it on the mytractor forum. Thanks

I was hoping for a bearing number

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

Is the spanner regular righthand thread? I have not had any luck with impact. Plan to use lots of heat next. Thanks

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.

Is there a difference between RS and 2RS?

the bearings are $4.26 each at Fastenal. Shop around . Some places wanted $20 per bearing

bearing is a 1641 2rs basically a 1" x 2" x 9/16" bearing

Just put together a "tool" to attempt taking these apart, are they normal or reverse threads? (before I mess this up) thanks

I KNOW VIDEO WAS A WHILE BACK but can anyone tell me if a gravley pro turn 152 with bearings # 59215400 can be rebuilt ? Thank you

Can you explain how you removed the pulley from the top of the shaft. Tried a gear puller and only managed to bend the pulley.

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

I have built a impact wrench like you have but is it the normal threads? Lefty lucy. to remove the retainer nut?

Where do you get the brgs

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

My bearings are good. I simply want to add zerk fittings and grease my spindles. Why can't I do that?

is it right hand thread or left hand thread

measure it inside diameter and out side and width with a caliper. Google bearings you will find a replacement.
