8N - 9N engine in a 2N chassis??

JC-jetro · Mar 27, 2008

Ak,

I had a friend that inherited a tired ole 8N from his in-laws, had a hard time getting to engine run predictably and also had compression issues. What he did was , took the head off, did a valve job, bought new cylinder sleeves/ piston and rings and a gasket kit. Took the oil pan off from the bottom, removed the crank/piston. Had to destroy the old sleeves to take them off. New sleeves was hard to push in... we kind of brain stormed it

. We decided for him to put the new sleeve in a plastic bag after he lubed it a bit, he latter put the sleeves in the freezer for couple of hours, had everything lined up , got the sleeves one by one out of the freezer and pushed them in the hole almost effortlessly. he pushed the pistons in from the top and got the cranks attached and torqued from the bottom. He then put the head back on, put the bottom pan on, oil and water and he was good to go. Did not cost him an arm and a leg to do, parts are readily available and it is relatively a safe project with the tractor standing up while you do all the work. That may be the way to go..Of course if Soundguy blesses it

JC,

Hey.. I'm a fan of 'whatever' works. While we all know a full rebuild is always the best bet.. we've all been there when money was short, and a ring job and some gaskets new crank bearings were all that we had money for. that usually got you a few pounds of compression, and a few psi of oil pressure, and cost less than 50$.. etc.

If you really wanted more power do something like this...

Useless power though.. trans, pto and rear end are all built around a 30hp machine. Even with 110 eng hp, you won't get much more than 30 down the pto shaft. The stock 27hp engine is quite capable of twisting the oem pto shaft.. thus more hp will be able to twist it off even more.

Pinion and ring gear might take maybee up into the 40's hp.. but that is on the edge.. mor ethan that and you will be shearing rivits.. or worse.

All this has to go thru the trans.. which again.. is designed around a 30hp machine.. same with the clutch...

a 110hp v8 8n is just for braggin rights...

Back about 1952 the Funk Brothers of Coffeeville, Kansas offered a kit to convert the 8N to a ford truck V8 engine or a 6 cylinder engine.

I have a Sherman Step up gear for 8N, 9N, 2N or 4 speed transmission Jubilee,600 or 800 for sale. It is used. To install it you have to split the tractor ahead of the transmission, remove the transmission input shaft and bolt the step up gear in it's place. This gives you a standard speed and a stepped up speed for each gear in the tractor. Is anyone interested?
