8N with 9N motor, how to order parts

Appleattic · Dec 20, 2012

I inherited a running 8N when my father passed away a few years ago. It is in pretty rough shape. Problem is it has a 9N engine in it, which I found out when looking for the serial number on the block behind the oil filter. So many parts are before or after a specific serial number. How do I determine which parts to get? Dad always told me the tractor was a "48.

Parts I need include parts for the steering box(early 4-bolt style) and hydraulic parts as the drawbar drops over time when the tractor is not running. Will also need front spindle bearings and seals, and undoubtedly more stuff as I get into repairs.

Am a novice at this, so any help would be appreciated.

so far.. of the parts you have named , only the steering parts are sn specific, .. becaus ethey are steering box specific.

thus you look at your steering box. if it has round covers.. it's early. if it has oval covers it is late.

order accordingly.

most of the other sn changes involve the distribuitor type ( thus block type ).. since you have a 9n / 9n block.. all your stuff is front mount.

past that.. you will see axle seal issues based on early or very very late trumpets.

you can look at trans shifter, hump in the tranny.. date codes.. etc.

no mystery here... ez to figure out.

The 3 point parts are pretty easy and the best thing to do is go with the new improved NAA type cylinder piston and ring set up which will make the 3 point work better and maybe even stay up. If it drops in say 10-15 minutes I would not even worry about it

Sorry to hear about your father.
You've got a great tractor there.
Doesn't matter much if it has a 9N motor in it for using it.
If it still has the 8N steering and axle, you will need 8N parts for those.
8N front axle should have the radius rods hooked to the center section.
9N/2N radius rods would be hooked to the outer/adjusting pieces.
As SG said, you can tell if you have early or late style gearbox by looking at it.
If you want to know if the year is close, there are a couple of other things
you can look at that may get you in the ballpark.
Casting numbers on the rear axle. (probably most reliable)
A solid metal shifting lever, or a screw off "plastic" top?
Proofmeter in the dash, or the older style dash?
Take a look at John Smith's site for good identification info.

There should be a number of cast dates that will help you determine when it was made. Look on the bottom of the rear axle trumpets and you should see a cast date. Your tractor will have been assembled shortly after that.

Thanks to everyone for the input. I"ve been reding some of the other links and getting additional information. So far I"ve replaced the manifold gaskets, brakes and seals, exhaust pipe, and 1 rear tire. I have a parts catalog and will get the repair manual in a few days. This looks to be a long-term effort, but at least I can roll around and stop when needed! I suspect I will be back with more questions as I proceed. Thanks.
