Hi All,
I'm new to TBN and this is my first post although I have spent many hours lurking before I decided to register. This forum is a great resource. Thank you all for your contributions!
A little history... A friend just bought a JD 4010 diesel basket case tractor that has passed through a few local owners since the last time it ran. No real history on the problems it may have had. The P.O. said the injector pump needed a rebuild and we seemed to confirm that with very low volume/pressure at the injectors. My buddy decided to R&R the entire fuel system, so we pulled injectors and I ran the bore scope into the cylinders through the injector holes to find heavy scoring and mild surface rust in 4 of the 6 cylinders. The oil looks good (for oil that hasn't been changed in a decade), no water or obvious shavings. I can't seem to find my compression tester but this tractor would only sputter on ether. I think that tells me all I needed to know.
We're hoping to do an in-frame rebuild. Neither my friend or myself have rebuilt a diesel or a tractor engine for that matter but have plenty of experience with automotive/gas engines. That leads me to a few questions I hope you all can help me out with.
1) What's the best way to get the sleeves out? I was thinking a bottle jack blocked up from the shop floor but I have no idea how realistic that is.
2) My buddy says he has heard the 0.125" larger sleeves/pistons for the 4020 will retrofit to the 4010. Any confirmation or gotcha's on that?
3) Assuming no issues with question #2, will there need to be any modifications to the injection system to accommodate the new larger engine?
4) This project has already overshot it's budget by 3x. I found a complete kit online for around $1500 and my buddy says he found one for $1200. Both seem reasonable but do you guys have any other parts suggestions?
Thanks in advance,
John
