I have been searching for a video showing these steps for months. Cheaper to rebuild with quality bearings versus purchasing new units. Thanks for posting.

Great video Lonnie. I just replaced the bearings in my spindle on a 2006 gravely 260z bearing number RA100PP if anyone needs it. They lasted 1600 hours. I wanted to mention some of the issues I ran into that you didn’t seem to have. Getting the pulley off the shaft from the start was a nightmare for me. This pulley of mine was a on the right (shoot) side of the deck so it was 2 stacked pulleys ( the top pulley being for a bagger). The way this pulley was made there was no good areas to grab the pulley to remove it from shaft without damaging it beyond repair. So to avoid from ruining the pulley I made two homemade spanner wrench’s. One to fit the two holes on top of the pulley and one to fit the nut on the bottom of the spindle. The nut was terribly tight and I had to use pipe for more leverage to get the nut broken loose. Once the bottom nut is removed from the shaft I was able to knock shaft of the spindle housing so now I’m left with a shaft and the pulley still attached on top side. By taking the shaft out with the pulley still attached this now allowed me to put the pulley and shaft on a shop press which gave me more surface area to hold the pulley while the shop press pressed the shaft out. Ultimately this saved me from potentially damaging the shaft with a pipe wrench and also allowed me to save my pulley without damaging it beyond repair. 3-4 total hours and $20 bucks for two bearing to complete this job. Much cheaper than $190 spindle and I also learned a thing or two. Hope this helps! Great video Lonnie!

Your video was very informative and I couldn’t find any others to explain how the spindle came apart. After trying to remove the inner shaft to replace the bearings. I’ve tried heating the threaded area and adding PB blaster then after it cooled down, I clamped the keyed end of the shaft in my vise and tried removing the shaft nut. Once I found your video, I used two pipe wrenches and it has not moved at all. Either the threads are rusted together or red loctite was applied when this was put together. The keyway on the shaft is damaged now from the pipe wrench, so I’ll have to buy a new spindle. Thanks again for the video.

Man this was a great video i have the same model gravely in a 44". Tough mowers. But i can defintly hear the bearings howling in one of the spindles. Now i know i can save myself about$500 by just buying the bearings. Thanks.

This works on the newer gravely mowers also (I have a zd44hd). Same bearings also but can be found cheaper on Amazon (use the bearing number from the video to cross-reference). Couple of notes: 1. I had to use a pulley puller since I bought my machine second hand and was neglected. 2. Unscrewing the spindle rod was a huge PITA. Ended up using a torch and two 18" pipe wrenches with a cheater bar. I think gravely is red loctiting the nuts. 3. Took the bearing seal next to the flange (side closets to the spacer) off. 4. Drilling and tapping housing to install zerk fittings. Should last till the deck rots out as long as you squirt some grease into the spindle.

Excellent video. This is my next project and your video is very helpful. As a matter of fact this is one of the best instructional videos I have seen, of any kind. Well Done and thank you.

Really nice video and explanation of how to service the spindle.

Good job mate thank you I am going to do mine now

Replaced spindle on my Gravely 48 in. zero turn two years ago with factory OEM spindle. $189. Originals lasted 8 years. Just last week it has gone bad. This time I ordered aftermarket one on Amazon for $89. Almost as cheap as buying two bearings and less trouble. Will see how long this one lasts. Sealed bearings suck. Cars no longer have grease fittings on front end parts either.

True AlphaMale here, thank-you sir!

Good job

I have a Gravely ZT48 HD.I wonder if anyone knows the bearing replacement part number for my machine.How did you figure that one out did you just take the old ones in and match up?Thanks for the video very informative.

Thanks.

Awesome, thanks 🙏🏼

Thank you for this. Kindly name the charity of your choice.

is this same spindle as 44z ? Great job !!

You should fill that spindle housing full of grease it will get in there and you'll never have to change the bearings again

You should put brand new bolts that hold the spindle on and put stainless steel so they do not corrode
