Interesting 8N

Well-known Member
Today, I saw an interesting 8N in the shop at my local CNH/Kubota dealer.

Though it had been modified, it appeared to be early 1950 as it had neither tach nor tach cable provision on the governor, but the governor casting had cast-in tach cable provision that had not been machined. It also had a Bakelite shifter knob and 4 bolt steering gearbox.

The engine had a side mounted distributor (more about that later) but 9/2/front mount 8N forward positioned oil filler tube and oil filter. The owner had fabricated a new oil filler tube to snake the oil filler tube below and behind a left side mounted GM alternator. The oil filter had not been repositioned.

The distributor was a GM HEI electronic unit from the 1970s-1990s. Beneath the distributor was a gearbox/adapter to fit the distributor to the front engine casting. The gearbox/adapter was lubricated with engine oil as the return oil line from the oil filter went to the gearbox. A second oil line went from the gearbox to the governor.

The tractor has several other owner fabricated modifications and doo dads. It would start and idle at 400 RPM or so with a touch of the key.

It would be interesting to SEE the HEI adaptation were's the fudgen PIX :wink: Those distributors have been adapted to about every thang know to man like a denso starter they are hard to beat... Simple efficient and cheap to fix..

For the price of three quality points sets you can buy a complete dist. that has cap, rotor, and coil all you need to add is plug in a 12V power supply for most popular automotive applications:) They will put out 40KV Easily blindfolded...

Of course you knew dat and knew that's the biggest reason it lit off at the blink of a eye..
 
Sorry, Hobo, but no pictures. I did not have my camera with me and have no cell phone, nor do I use photobucket or the other sites necessary to post pictures here.

It was interesting, though.

The engine had the 9/2/early8N oil filler tube and oil filter location but was a side mount distributor. Unlike the right angle distributor in TOH's photo, the distributor gearbox/adapter was inline and the distributor was in a similar position as the OEM side mount distributor but very close to the hood.

Most interesting of all was the gearbox adapter. It was about 3 1/2 - 4 inches in diameter and about 3+ inches tall. It was obviously lubed by engine oil as the Oil filter return line went to it and another line returned oil from the gearbox to the governor.

I may be back there tomorrow. If so, I will take my camera and take some pictures. I'll need to email them to someone for posting, though.

I took some photos of the adapted distributor this morning. Send me an email and I will send them to you.

He removed the shroud and modified the fan for clearance. Not sure how that would work if working it hard.
 
Someone did a nice job of trimming the hood side panel rerolling the edge to clear the distributor.

I also find it very interesting that the alt. is mounted upside down as we know it. The pivot mount is located on the top and the adjuster mount is located on the lower side.

Someone is no copycat!

That's an interesting angle drive. Here is another one. Reproduction Vertex angle drive for magnetos or Nash twin 8 distributor. Very popular with the flathead V8 junkies. Monterey Speed is practically giving them away for the paltry sum of $1,950. Perhaps I should revisit that project ;-)
