Steering Shaft (lower) Question - B-80

I need some confirmation from some experts please!

The quick background is that my 1975 B-80 has had "slop" in the steering for some time, jumping teeth any time you attempted to turn the wheel when stopped or slowly moving.  The gear teeth on both the upper and lower shaft were worn, but the lower was worse and when I found one at a good price on eBay I finally decided to do something about it,  After a lot of cursing, I finally got the old one out, but when I went to install the new shaft it would not fit.  A comparison of the two parts shows the new part to be at least 2" longer.

So my question is, am I correct in assuming that the lower steering shafts remained constant for all four years the B-80 was built?  I ask because the shaft was sold specifically as a B-80 part.  I haven't contacted the seller yet and I have no reason to expect any difficulties returning the part, but before I claim the part was misidentified, I'd like to make sure I know what the heck I'm talking about.

Also, while you can't see it very well in the photo, the shaft from my tractor (the shorter one) has three holes below the gear teeth, the new one does not.  Can anyone with a B-80 confirm their's does/doesn't have the holes?

Any input would be appreciated!

1974/75 B-80 4 speed models were a "medium frame" with a (roughly) 43 1/2" wheelbase.

 

1976/77 B-80 8 speeds were "long frame" models with a (roughly) 45 1/2" wheelbase.

 

The difference is in front of the footrest mounting bar, so the lower steering shafts are different lengths.

Thanks TT...that would explain it!

For what it's worth, I did discover that when I got the old part out that someone had erroneously put one of the spacer washers between the steering shaft and base instead of on the "cotter pin" side.  When I reinstalled the old shaft I put the washer (and one more shim) on the correct side and the steering hasn't jumped a single time, including in all the snow pushing I did last week.  

So, it's still a win!!!   :banana-rock:

My '74 B 80 does not have the holes and is 16" from the front plate to the end of the shaft in the rear where the gears are. Hope this helps.

      36" deck mower bearing assemblies
      By Jeff_B
      Where's your go-to source for QUALITY 103119 bearing shaft assemblies? Also, I don't have my deck apart yet, but seem to remember they're tough to remove from the housings. Any tips or tricks? Finally, just recently I've had a couple of  the center bearings go loose on two different decks. Once is one thing, but twice? More than a coincidence? Should I be releasing tension on the belt by loosening the mule drive when not in use? We've had WH tractors for over 40+ years and I've never done that before! THANKS in advance!

      D series Steering
      By BMW1
      On my D200, when I turn the steering wheel all the way to the left, it has a tight turn radius, but when I turn it all the way to the right, the turn radius is significantly wider.
       
      The tie rods appear to be adjusted evenly.
       
      Anyone have a similar problem and what was done to fix it?  The steering does have quite a bit of play, at least 1/4 to 1/2 turn of the wheel.

      Leaky steering fitting lube fitting?
      By Off Track Horse
      Okay, so I just know just enough about engines to do basic care & know when something is wrong.  I have what presented as a hydraulic leak on my 416H with fluid spraying everywhere from under the center of the tractor and it is really only significant when the PTO is engaged.  I took the mowing deck off today expecting to find a cracked hose or loose fitting.  Wrong!  Instead I found fluid coming out from the steering shaft on the opposite side of what I am finding is called the "steering fitting lube" piece on the Toro parts website.  So where it shows part #7 going in the fluid is leaking out of the other side.  I'm really at a loss on this one.
