We had an MF FE35 - Standard 23C, parts like injector lines (among things) are near impossible to find. It sipped the fuel, ran smooth, but with out glow plugs and a block heater, was a hard starter. I know of one guy who plumbed in a Thermostart off a Perky 3 cyl, and it improved it a lot.
i got the perkins in mine, fastest starting diesel i ever seen.radiators are hard to find,i had to put one out of a 135 in mine.i paid $2500 20 years ago for it,still going strong.
I'm not affiliated with them in any way. But I used them for parts on my MF250 diesel engine rebuild and they are nice to work with. Easy to talk to on the phone (asked lots of questions, and they were helpful), and they gave me good parts. (If you have trouble searching for what you need, just call them.)
I did a quick search for "MF35 Diesel" on their site, and they've got lots of stuff listed for parts...
They are also fairly local to me, which I liked as well. (115 miles away)
I have a mf 35 Perkins that I am going to part out and a engine block and frame for a mf35 standard diesel, call 423-421-6034 with needs. I am in east Tennessee..
