Ok Ilooked at an 8N today that has about 45 PSI oil pressure. I have read that you can jack up the oil PSI somehow, is this easy to do ?? How do I know if someone did it to this tractor ??

The Ser # is 8N6050AB also number SCCC45 what year is this ??
Thanks

Run it 30 min,,, git it hot,,, werk it if you can,,, if the OP does not fall off much say no more than 25 on the low side don't worry bout it.

It would B extremely difficult to bring the OP up on a worn engine,,, almost impossible if not impossible.

Rebuild price
$300 to $2000,,, depends on what has to B done and who does it and what one would call a fresh reloaded bullet.

Ken;
You are correct, that # 8N6050AB, is the part# for the head of an 8N.

It is NOT a ser.#. In fact that # is on my 2N head. I believe the AB part of that #, depicts the series of 8N that head was made for.

The #, on my 2N is 8N6050B, and is a replacement head, installed by the prev. owner. I ask him about it when I bought the "N". He also stated that there were numerous 8N parts on my 2N because they used an 8N parts tractor to build up my 2N.
Happens quite a bit.!!!!!

I think the serial number you are giving (8N6050AB) is a part number!!

ok,if I could get say a 52 for 2k that was running and all worked well and it had good rubber and was painted but not a pro paint job, the tin had some dents etc 6 volt and started and ran good brakes good is it worth 2k ?

Is there anything that could be wrong I could overlook that would cost big bucks to fix ?

The engine would have to B in rite good condition to even jack it up,,, like it has been said,,, whats the OP Goon'n hot werk'n. I have a n that has good OP cold 25 psi or so and holds 15 to 20 hot,,, werk it hard plow'n and it gits down to "0" or close,,, its git'n a rebuilt bullet installed soon

I have no use for a 180 degree thermo,,, my tractor run around 190 with the 160,,, I werk'em not show'em,,, treat'em like a red headed step child,,, if you live in a cooler climate I recon it would b worth wild,,, or use it much in the winter,,,not here tho,,, they pretty much git a rest in the winter,,, Put to werk in the summer

what is a bulett ? what would be done to get the pressure up ?? Is it safe to run with 10 psi or lower ?? On the t-stat what end goes toward the radiator the spring end ??

ifn it does have low oril pressure what would it need to have done and how hard to do it and how expensive. Like what rings ? rod and crank bearings ??

Better to run a tstat. It keeps the engine at a even temp...That = even ware on the engine. No tstat the engine will run hotter in some areas and cooler in others..They run better hot!!

should you ALWAYS use a t-stat or is it ok to run without one ? It seems as thought the coolant was flowing even before it got warm, not bubbling just moving some, does this mean it doesn't have a t-stat ?

One on ebay. This is the one I got. It is a 180° thermostat and half the price of the 160° 9n 2n 8n thermostat... Helms tractor on Ebay

If your # starts with 605 and its a side dist model it would be a 1952,also the thermostat is sometimes held in place with a hose clamp around the hose in the middlke of the upper hose

Squeeze the upper hose. If you have one it will be in the hose. They are held in place by a plastic zip tie...

Your serial # doesn,t make sense,are you sure thats the #? Is it a side distributor model?As for oil pressure my 8N runs 45 psi when cold and 40 when warm but it was just overhauled.

You should be able to feel the thermostat in the upper radiator hose. Type of oil in the engine also affects the pressure. 40 wt will get more than 20 wt.

ok..well how long would one have to run the tractor to get it warm enough to see the diff if any ? And how low is considered too low of oil pressure ? I am just trying to figure out how much to pay for a tractor that may have oil pressure problems and if it does how easy to fix and about how much it would cost ?

Probably hard to say I would guess but I would hate to pay say 3k for the tractor then have to put more into it right ?

Osweld:

These days in my area only an exceptional 8N will bring $3K.

I would not consider paying $3K for an 8N if there was even a question as to the condition of the engine.

Osweld:

Its rather easy to increse the cold oil pressure by shimming the pressure regulating valve spring or replacing the spring with a stronger one.

That said, cold oil pressure is not very useful in determining the condition of the engine. Oil pressure when the engine and engine oil is fully up to operating temperature and the engine is at idle speed is far more meaningful.

Shimming the regulating valve spring will likely have no effect upon the hot oil pressure when the engine is at idle speed.
