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.
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.
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.
Yes absolutely. Your video was probably the best one out. Was your original bearing manufactured by Peer by any chance?? I was wondering where you got your bearings from. I went to a supposed dealer of timken, he originally sold me ra100rrb, which is a beveled outer race. I told him that I believe I need the ra100rr bearings and he tried telling me the rr's are beveled as well. Well after seeing your video, I know they're not. My biggest fear of using Amazon for bearings is getting counterfeit ones. Its Absolutely terrifying the stuff coming out of China.
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.
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.
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.
You're welcome, and thank you kindly for the thought. As long as it saved you time and money I will let you choose a church of your choice and take a tax right off as well.
@@LonnieJohnson1 when I change my three spindles last week the bolt heads word deteriorated I had to use the easy outs on some of them they all came out but a lot of the heads were crumbling I should have kept the bottom of the deck soaked with diesel over the years to keep this from happening are used motor oil
@@LonnieJohnson1 CRC makes a bearing grease for sealed bearings it is used on electric motors with sealed bearings I just replaced all three spindles on my Gravely 460 that I have had since 2008 the spendals just started to go out one was bad to was almost there and 3 was okay I filled the new spindles with the CRC electric grease if nothing else it will keep moisture out to some degree the bottom of the deck is what seems to be getting corroded if I would have known I would have sprayed it with diesel from day one to prolong the life of it anyway the entire deck got cleaned and blasted and cold galvanized and repainted hope to get another 10 years out of it
