My current 'project tractor' is a JD 5105 which I purchased last December from an estate. Seems the owner passed away and his stuff was being sold private treaty by the heirs. Tractor had last ran in mid-summer 2023 and a stepson had been trying to get it to run for a month w/o success. We figured is was lack of knowledge and/or mechanical skills and new fuel and filters would get it up and running. WRONG
The amateur mechanic had run a line directly from fuel tank to injector pump bypassing the fuel filter. Whether this made the situation worse or not, I don't know but the result was a new injector pump and injectors.
After a lot of frustration and parts shuffling, we finally got it running today. Still a lot to do replacing wiring, replumbing the fuel lines, changing oils and filters, and all sorts of small stuff. Working when weather permits also slows progress but I'm feeling much better about this project now that I've heard it run.
My Cousin is a JD mechanic and I'm hoping I can bribe him into adjusting the timing on the new pump. I'm assuming this a requirement for making it run properly?
 
Inj pump timing can be changed by rotating IP location on engine when engine isn't operating. Which 5105 do you have the one manufactured in Augusta, Georgia or India?
 
'Little Johnnie' lives. After much fiddling and piddling, I got the fuel leaks sealed up to the point at which I no longer have to bleed the filter each time I try to start it. My Cousin ( certified JD mechanic) showed up yesterday and fine tuned the timing of the new injector pump. Still lots of little stuff(lights/wiring/cosmetic) left but basically a running machine now.
 
First hydraulic oil dump looked sort of like chocolate milk. Second dump after approx 15-20 minutes run time looks more like oil w/o the curdled milk. I figure one more will make me more comfortable and then another prior to hooking up the rake hitch in June. After some searching, I've been able to source hydraulic filters for much less than the $100 each parts counter prices. ;)
Just a few more nuts and bolts to replace, re-plumb a steering line, and it'll be ready to remount the loader.
