hpeeler 0 #1 Posted June 15, 2012 I need to replace the spindles on my 48in deck. Do I have to take the entire assembly out to get the spindle out or should it just come out? Does it have to be pressed out? Will blade alignment be an issue when I put the new ones back in? Thanks for the help. Share this post Link to post Share on other sites
WH520 17 #2 Posted June 15, 2012 Is it tapered or keyed? All of my decks have had a tapered spindle. First remove the grease fitting and belt. Then take the nut off that's on top of the spindle and tap the spindle with a hammer and it should pop right out. You don't have to touch the spindle housing. To reinstall the new spindle just slide the spindle through the housing, install pulley and tighten the nut. Put the grease fitting and belt back on and you're done. This is for a tapered spindle, I've never messed around with a keyed spindle so this may not apply if yours is keyed. Share this post Link to post Share on other sites
Don1977 604 #3 Posted June 16, 2012 Why are you replacing the spindles. I have had two spindles damaged in 35 years one was a 3/4" keyed that key slot wollered out. The other the blade nut stripped, I retreaded the spindle put on another nut and got by until I got a new spindle. I've changed a lot of spindle bearings in 35 years. I'm not saying that you don't need to, just wondering why just the spindle. Share this post Link to post Share on other sites
can whlvr 993 #4 Posted June 16, 2012 i too recommend that you do the bearingsif you are doing the spindle,if the spindle is worn out good chance the bearings are too,i screw a bolt in place of the zirk,put 2 or 3 nuts on the top of the spindle one protruding up above the spot where the zirk goes and then you can hit it good,but if its trashed you dont need to worry about the top of the spindle Share this post Link to post Share on other sites
Don1977 604 #5 Posted June 16, 2012 There is a big C-clip holding the bottom bearing in that has to be removed before tapping out the bottom bearing. Share this post Link to post Share on other sites

I'm not saying that you don't need to, just wondering why just the spindle. Over the years sometimes the blades would get loose and spin freely before I realized it and that has worn on the spindles. I have had to put 2 washers on them so now the nut doesn't grab enough for my liking. I have 3 keyed spindle assemblies from a 48" deck. PM if you're interested. I don't know if mine are keyed or not, I haven't taken one out yet. It's a late 80's model if that helps you. If I can get one out in the next day or two and see that they are keyed I will pm you. Thanks. Share this post Link to post Share on other sites
SAM58 30 #8 Posted June 18, 2012 I would take them out and fix all that needs to be fixed. Bearings and seals are cheap for the 48" decks and chances are that is all you need... Share this post Link to post Share on other sites
Don1977 604 #9 Posted June 18, 2012 If they have a 5/8" nut on top of the pulley they are Metric. If they have a 3/4" nut on top of the pulley they are keyed. The spindle housings and mower blades are the same on both every thing else is different. Share this post Link to post Share on other sites
hpeeler 0 #10 Posted June 19, 2012 Mine has a 15/16" nut on top of the pulley. I took the nut off of the pulley and tried to hammer the spindle out from the top. No deal. How much disassembly do I need to do to get it out? Am I missing something obvious? Thanks for all the help Share this post Link to post Share on other sites

Be careful if it's rusted in the bearings you could bust the alum. housing at the bottom where the c-clip is holding the bottom bearing. Share this post Link to post Share on other sites
