Engine rebuild on an Ford 8N Tractor

Recommended Posts

Jrblanke

Hey guys,
Long story short, my uncle has a Ford 8N that he got from my Grandpa. It has seen better days, but it runs and drives, it just doesn't have much power. i am going to do a compression test this weekend, but I am thinking its just tired. 

My question is this: How much do you think it would cost to have someone rebuild the engine? Also, how much would it cost if I were to rebuild the engine (I would still have to pay someone to do the machine work). What are the best bang for your buck engine rebuild kits? 

I would love to either rebuild the engine, or have it rebuilt as a surprise for my uncle.

If I recall correctly 8ns use dry sleeves. You pull the old sleeves put in new ones, new rings, and usually new piston/pins.

Only machine work is to get crank reground and maybe valve seats.

They use shell bearings on rods and mains so after your crank is ground I guess you can order them...(Better than my Case DC3 which uses poured babbit bearings.

The do it your self route gets to be a problem when you have to buy a sleeve puller

Ouch$$$ and the disc you need is not included that will be another $100 
If you are handy you can make your own  I have a picture of a home built somewhere I will post if I find it.
