Son, purchased a Original Cub mower deck to go with his Cub Original. It was in descent shape but needs to be repainted. Since he works 50-60 hrs a week thought I would help him.

Ran into issue of removing the "Spindle Shaft" #8 Bolt. I am afraid of breaking the "bearing housing" #30 so have the pulley puller on it really tight hoping PB Blaster and pressure finally loosen it (a). have gotten the shaft to move some but not enough to completely be able to punch the "key" #26 out so as to remove the "Blade drive Block" #27 (b). Don't want to use heat due to afraid of damaging the bearings (they seem to be fine that is why got this deck as apposed to the other decks the guy had for sale).

Any thoughts on removing shaft or do I need to look at cutting shaft at the "blade drive block" to get the housing off so can take more of the deck apart and end up buying new bearing and shaft etc.

I wonder if a bearing separator might be a better tool for the job.
You may be able to get a loaner from Autozone.

Do you have the service manual for the timed mower deck? If not, these pages might be helpful:

Once you get the key out of the Blade Drive Block (#27), just unscrew it and remove the spindle assembly

I have the spindle shaft just about far enough to get the key out to unscrew the block. i have even tried a punch to knock it out but not quiet there yet.

kmcconaughey - thanks for the manual pages - the part i am stuck at is the #9 drive the spindle shaft out

bjames - i have bearing separator mine not large enough so need to go to autozone and borrow one.


Thanks to all for the replies.

well guess soaking it with PB Blaster for a week worked, couple of smack with a hammer spindle shaft moved enough to get the block off, but as my luck have it the one bearing was shot. (n) :mad:

still need to get the one bearing off, so looks like will see about getting 4 and new spindle shaft, cant really see in picture but the bottom half is worn. found the below on another web page.

and have not clue what year the deck is, so may need to see if dealership knows. or doing some measuring and cross reference
*****looking a part man. closer it is an 60-61 deck

Unless those bearings are something really strange, googling the part number etched into one of the races should lead you to replacements.

Forgot to mention this deck that son got used, appears to be an early style (60-61/62), has triangle plate vs square.
The left spindle assembly has a spindle shaft that had a grease fitting. The right spindle is sold and the shaft is worn due to bearing failure.

so I am assuming that this deck has been worked on.

So are two different shaft interchangeable with the LH and RH pulleys???
comparing the two shafts they seem to be same size though i didn't use a micrometer.

The one manual show non grease fitting one Part 464-534-R1.

Another manual has this ----
#8 - - SHAFT, SPINDLE - 1960 TO 1961 464534-R1
#8 - SHAFT-SPINDLE - SHAFT, SPINDLE - 1962 TO 1963 IH-470883-R1

Thanks for all the replies.
