How Do I Disassemble This Spindle?

Nailhead · #1 10-21-2015, 11:40 AM

I have an outboard spindle on my 42" that is all but seized. It'll turn with a ratchet and socket, but I can't imagine that the belt will turn it.

I removed it complete with the cast iron deck fitting, but I can't see an obvious way to dissemble it: there are no wrench flats on the blade end, so the only way I can envision getting it apart is oilfield style, using a large pipe wrench and ratchet.

I do NOT want to add to my problems with destruction, but I do want to get this spindle apart because I have a new set of bearings awaiting installation.

Thanks for any help.

Need more info on what your working on. If you look in the tech library you will probably find the service manual for your deck.

If it's from a triangle style deck with the cast iron center: Remove the bolt that the grease zirk is pressed into and the pulley will slide off of the center shaft.

The pulley does NOT unscrew from the shaft, it is keyed.

Thank you for the reply, and pardon the misclassified post.

I understand the principles behind the assembly (I've worked on everything from Evinrudes to Unimogs over the last 40 years), but I'm looking for some ideas on the method of disassembly.

I realize that bolt has to come off, but given the lack of wrench flats on the other end of the shaft, is using a pipe wrench to grip what appears to be a 2 1/2" diameter sleeve on that shaft a good idea? Those 40 years mentioned taught me long ago how quickly things can go from bad to worse with the misapplication of a bad idea.

Thanks for the suggestion.

I didn't find a manual for the one I have, only the one without the cast iron fittings on the middle & ends.

If you took off the blade reinstall it and then remove the nut on the pulley side.This way you can chuck the blade up in a vise to hold it.Remove from vise,then drive out the spindle shaft from the pulley side by screwing a bolt in the shaft similar to the one that you removed from the pulley.

You can do what Lew said or you could also put a wrench on the hexagon shape that is the top of the pulley and then turn the bolt out with a 9/16" wrench.

what he said.

I thought he was inquiring about the center one.

Thanks for the info, everyone!

Rust forces me to bring up a few questions:

Is that sleeve on the spindle shaft supposed to be permanently attached?

Does the spindle assembly separate from the cast iron deck fitting?

At this point, I am really starting to think I should break down & buy a new spindle assembly, only because I don't have a way to press out the outer bearing races & install the new ones I have.

You drive the races out with a punch. They're just like older style front wheel bearings on an older car except there is a spacer between the races. If anyone has a copy of GSS-1355 it shows how to take it apart. I don't have a way to scan mine right now.
