A "How To Pictorial" - replacing a spindle and spindle housing

I was a bit weary as I have never made this repair before. It was VERY easy. Here's how to do it for those who may need it in the future.

Replacing the spindle on a TTHP 36"

Here she is:


First take off the cover, then remove the belt by removing tension with the brass colored pulley.


Take the bolt off the top of the spindle. I recommend an impact wrench for this! The pulley will pull right off. You may need a pulley puller.


Take the "key" out, and give the spindle a tap. It should fall out below.


Remove the spindle housing with the 6 bolts.


Slap the new one in there the same way you took the old one out. My kit came w/ new guards for the top and bottom.


Lube up the spindle, mainly where it touches the guards to keep dust out. (I wish I had this lube when buying the part from the dealer ).


Put the pulley back on with the key, torque the bolt to spec, put the belt back, and go!

This took less than an hour for me. An extra set of hands would have helped lots when removing the 6 bolts that hold the housing. So easy a cave man can do it!

Thanks for the info! What did the new spindle cost? Wouldn't a grease-able spindle last longer?

Did you put set screws on the pulleys/keys?

I have heard the greas-able ones can last longer. The old one lasted 3 years though. I probably need to spend more time balancing the blades, as this is supposed to help longevity.

The "cutter housing w/ bearings kit" cost me $125. Not too bad. I may try to get the old ones bearings repaired, and use it as a spare.

44DCNF, what are "set screws"? I don't know what they are so I don't guess I used them!

There are no set screws on the Exmark set up, The top nut holds the whole thing together

This was AWESOME help! This is the same process for a 2002 eXmark Lazer Z HP 52". Except for the Lazer z you have 3 spindles!

Just one question, do you have to remove the key on the pulley before you can take the pulley off, or does the pulley come off, THEN you have to take the "key" out to remove the spindle shaft?

Thanks so much for the post and pictures!!!

In most cases it's cheaper to replace just the bearings inside the spindle,
the repair takes longer but I have never replaced a spindle whole, just the bearings,
also on my Toros the pulleys all have set screws.

Bearings alone run ya about $25-$50 in parts, the entire spindle's closer to $75-$90...
Takes an hour or two longer.

Thanks for the help. Ironically I am doing one today. It didn't look all that hard but the step by step makes me a lot more confident.
