450 gas to deisel

how difficult to convert from gas to deisel (58 450) where can i find engine and parts.

Pretty tough conversion. The real issue is that the 450D engine is the last year they were used (gas start/diesel run. They are complex units that run well and are efficient, but spendy for repairs, and parts. They are as good as the gas on power.
Linkages are tough. Hood hole is wrong, Fuel tank for gas operation, And many more. A doner tractor would be best, but then just fix that!.. JimN

While the chassis are mostly the same to install a IH D281 engine I will list some things that come to mind that need changed or added. Both hood sides, fuel tank and all lines, starter, correct generator and mounts if wanted, hydraulic pump and suction discharge lines, air cleaner and pipes, part of throttle linkage, switchover lever and linkage, starting fuel tank, fan and shroud, hand crank parts in bolster if wanted. frame rails, flywheel, some wireing, power steering mount if equiped, oil pressure gage. Probably forgot something. This above is if you have a complete engine with all outside parts. I know you didn't ask for a opinion so overlook this next if none wanted. Your money ahead to buy a good running 450 D if found unless you already have the parts.

Before you even consider tackling a project like this, find a consistent, reliable source of tractor parts and information. You're not going to find a "Tractor Wal Mart" where all this stuff is vacuum-packed on styrofoam trays with all the parts you need and step-by-step instructions.

A project like this will probably start out with a pile of parts found in the back of some dusty old barn that you found through a friend of a friend of a cousin of a mother of a church group member. You need a local salvage yard to supply any missing pieces, and a local CaseIH dealer to supply wear parts like clutches and bearings and seals.

There's going to be a lot of figuring and fiddling, skinned knuckles and cuss words.

An essential tool for the job is a good beer fridge, kept well stocked.

In addition to all the good advice and comments in the other posts, let me add that the 450 diesel was the biggest engine, displacement wise, of the MD-400D-450D line and was the most prone to head cracking problems---which were usually the result of improper cooldown/shutdown technique and overheating because of the bigger displacement with the same, more or less, cooling ability. Also note that the 450 gas has somewhat more power than the diesel.....Now this can be argued, but look at the Nebraska tests on both tractors. In the past I have been around both and noticed the difference. I will readily admit however, that a good 450 281 cu. in. diesel is much easier on fuel than a 450 281 cu. in. gasser.
