Steering housing dowel pin

Postby cavingreer » Tue Feb 14, 2017 12:11 pm

Patching up the old feller to get some work done and trying to solve one of the major failures that the previous owner caused. They never put the dowel pin in the steering housing, which is why it's ruined all the threads and loses bolts. The hole goes all the way through the bottom so is that pin just tight enough to hammer in from underneath and stay?

And on the same topic, how do you safely support the tractor with the steering housing or axel off to work on it? The housing is the only thing other than the oil pan you can get to. I don't have an A frame or anything above to work with.

Get several blocks of wood and make some cribbing under the oil pan it will distribute the weight across the oil pan instead of in just one spot. You should be able to put the pin in from the open side of the hole, if your bolts have been loose now's the time to take it apart and put new seals/gaskets in it. The dowel hole may be wallered out and the pin may not stay. I used a 6"X6" and stuck it under ours, this is when I was putting it back together. Be sure and chock the back wheels!

I recommend putting the blocking under the bell housing, not depending on the oil pan to support the weight.

Well after tinkering all day on it I finally got it jacked up good and took the lower housing completely off. Anyone have the helicoil kit info handy? I've got my eye on the dowel pin, gaskets and seals from TM but I didn't see the helicoil kit on there

Some auto parts stores, Fastenal, etc. carry helicoil kits. I usually get mine from McMaster-Carr.

Let me know what size helicoil you need. I may have it. Unless you would rather buy it to have on hand. I come to Fayette on Fridays. You could come pick it up there

Thomas I just found the Helicoil brand kit in stock at O'Reily for $25 and going to pick it up shortly. I can be working on those while waiting for the seals and stuff to get here :) for reference it's Helicoil 5521-7. 7/16-14 with the tap, tool and 6 inserts. Just have to pick up a 29/64 bit

Bolt holes are pretty wallowed out on the lower housing since it's had no dowel pin. Think it will be reliable at all after I helicoil the threads or do I need to drill out and put some kind of sleeve in?

You'll be better off in the long run to repair the holes or find another casting.

I don't have one of them in front me to verify, but doesn't that casting have a lip that engages the upper half, keeping the shaft in line? Thus the single dowel prevents rotation between the 2 castings and maintains position? If so, the bolts only provide clamping force between the parts and are not needed to hold alignment. Although you would rather have unworn bolt holes, I doubt it makes any real performance difference. This assumes the dowel has a proper snug fit on each end.

Jim the PO didn't install a dowel pin so it's spent an untold amount of time wearing out the bolt holes, threads and losing bolts. I don't think it has a lip or anything to assist the dowel in holding the position, but the worm gear and steering gear are both in great shape considering and I believe the dowel hole is in pristine condition. I have the dowel ordered along with seals.

Hi,
You can turn the big gear, in your pic above, around 1/2 turn on the shaft, and then it will use the about 1/2 of the gear teeth that are never used. They should be unused, unless someone has turned it around before. Look closely at the teeth for wear.
If you want the 5 bolt holes in the lower casting tighter, maybe some small tubing that is snug on the bolts, and will fit snug in the holes will work. Cut it in short pieces and put in the holes.
They have to be slightly shorter than the thickness of the casting where the bolts go through it.
Not sure if this will work because of the way the holes are worn, if the wear is one direction, the holes would be odd shapes. You could look at it and see if this will work if you want to. :)
