Blade spindle replacement

Apologies - this is possibly the wrong list - but, it is pulled behind a 52 8N, 6v, side mount & I read this list daily - so does that count?

I've a Land Pride AT2572 finish mower. I hit an obstruction and the center blade has stripped the threads inside its spindle - I removed the blade hub (under the deck) expecting to then simply lift the drive pulley & shaft out of the hub and its two bearings. But it won't move. I've tried some vertical assistance w/ hammer etc... nada.

Now contemplating physical assault on the lower bearing (heck - its the only available target!). I'm probably missing something obvious. How do I replace the spindle?

Basically trying to replace part #47 on page 28 of www.landpride.com/ari/attach/lp/public/manuals/310-002p.pdf

Help? Advice? (or - redirection?)


On a more on topic question - can anyone recommend an 8N shop in the Kansas City MO area? I've had my 8N for some 25 years and while she only mows or brush hogs for some 30 hours a year . . . and I do have some mechanical smarts.. and fixed bits & pieces & oils & filters etc over the years . . . I know that she's approaching an age that deserves some more professional TLC.

Many thanks - Angus

Just a guess when you hit the object it may have
bent shaft and put it in a bind. Maybe try heat
and more hammering. On your N dont fix it if it
anit broke. 30 hrs at 25 yrs is 750 hrs. You
repack front bearings at 600 hrs I think if you
need to do that. If you have taken good care of it
changed the oil in it and the oil in the air
cleaner I would not let anybody mess with it. All
these Ns were well built all they needed to keep
going was routine grease & oils . A little smoke
is even acceptable. If it can hold 10 psi when oil
is hot your in good shape, anything above that
your fine. Use but dont abuse you got lots of seat
time left with it. Age has nothing to do with it.
Post back on your mower as we all like to see what
happens and post anytime on about anything.

Thanks Popgun.
Don't fix it if it ain't broke & when in a hole, stop digging - are always worth remembering!

Shaft rotates quite freely - obstruction was a slice of tree trunk left over from some tree felling. Big bang & instant, but untidy, log splitting.

I've not done this before, so dumb question - where do I apply heat? How much? presumably to the bearing not the shaft? Though they are in close proximity!

Also I'm underneath in a confined space, maybe I need to rig up a way of standing the mover up on its back end - so as to have better access. Don't really have the equipment for that though.

I would remove the complete spindle assy, 4 bolts!
I rebuilt a couple of JD Decks and just replaced the complete assy, Think that is all they sold anyway.

with the complete spindle out you can work on it better.

I started down that route (remove assy) but can't get anything but an open ended spanner on the nut & bolt. It wouldn't budge and was afraid of just rounding off the heads - so stopped digging in that hole! Maybe have to go back and reassess that approach. Do they make thin wall sockets ?
Thanks for the suggestions.

I have made a few thin wall sockets over the years. Even ground down a snap-on deep well socket 35 years ago that I still have. Had one turned down on a lathe also, still have it also.

I stand up my brush hog type mower with a come a long to get to the blades for sharpening. remove PTO shaft and top link and leave it hooked to lift arms. Don't remember where I hooked to tractor at but probably the bottom of the top link bracket. Once up I added a chain for safety.

Thank you, Mr Geiger, Sir.
You made me try again - clearly my sockets have shrunk overnight!
:roll:
Tight fit, but one bolt freed, I will soften up the other three w/ penetrating oil and then go for them tomorrow. Hopefully the whole hub assy will come free from the deck without too much resistance.

Post back when ya get it fixed or other ideas to
help.

The drawing shows spindles that look a lot like the ones on my KingKutter. I had all three off last weekend so my son and I could straighten the deck. I pulled the sheave on top with a three-jaw puller. Then I held the nut on the bottom with an open-end wrench while my son used an impact wrench on the bolt head. Only one gave us trouble -- on that one we ground the head off the bolt.

Thanks all! It's out and in pieces on the bench. Now waiting for UPS to deliver the new parts - that'll give me time to clean & prep. (and go check the pasture for other oppsies?). Hopefully next post will be to report job done. Thanks again.

Glad you got it apart, it will go back real easy. I would use new bolts and anti seize on them!

Just to close this thread out - Got the new parts, put it all back together, and got the pasture mowed before the rain came in. Felt good to be back in the seat. Many many thanks for the advice & guidance.
Unfortunately - now I need to start a new thread about what seems to be an exhaust manifold leak at 3+4.
