1864 blade removal

[Brian Miltenberger]

I do not know if the threads are left or right .I have tried both ways with no loosening of the blades.

Brian,assuming you mean mower blades.....my trick..a short piece of 2x4... rotate blade tip against 2x so it can't turn wedged against the deck.. typical left is loose and whatever cheater pipe on handle it takes to break it loose..worst case is heat because it may ruin the lower bearing seal..I've often used a 3 ft..some times an impact will get it when a hard pull won't....

A floor jack handle often makes an excellent persuader when fitted onto a breaker bar. Use one section, or the entire length.

Thanks wow they are very tight .3 quarter breaker bar and it just feels like I'm tightening.

My 106 has 3/4”-16 NF threads on the spindle shaft with a flat washer & Nut. Standard right hand thread. Clockwise for tight.

Maybe just corroded. Try Kroil or PB Blaster let soak for a while. If you have air and a 1/2" impact, rattle the nut on / off to assist on loosening

I used a 2x4 up against deck .split the lumber .it did move and get tighter.I know I was going the right direction to loosen.gave up mower for an hour.and center double spindle bearing gave out.so I'm shopping for parts now.

Now that you’ve gotten some movement, can you work it back and forth, and maybe expand the range of movement?

Also useful techniques mentioned previously were spray threads, and heat the nut. Can you see any thread damage?

 

[gary noblit]

Brian, it sounds like nothing left to lose so heat just the nut. You could (maybe) spin off the top nut then carefully drive the assembly out the bottom.Be sure to keep driver centered or risk ruining the threaded shaft...Once out you can put shaft with blade still attached in a vise and apply lots of heat..I've done this several times...You have to be cautious not to mar the shaft...

All good ideas and techniques.We should all say a prayer for the guy that over tightened this.It didn't need to be this tight.Every assembly has its proper torque.Over or under has consequences. A good 6 point socket ,and replace that nut if its messed up.
