I just acquired a 1650 as a project, and am looking for some general info while I wait for the manuals. It is missing the engine block, crankshaft, and front wheels. I need to know the size of the front wheels/tires and year of manufacture. It has 15.5/38 rears, and does not have the hydra-power. Also will be looking for a good used or rebuildable 283 diesel in the future. I think there are two versions of this engine, direct or indirect injection? I'm not sure which one it had, it has stanadyne pencil injectors, but has a preheat decal on the dash. Maybe an earlier conversion? It has a wide front, but was originally narrow front and was converted by my uncle in the 70's. It belonged to my uncle until he sold his farm and has been sitting in the weeds for 10-15 yrs, the block and crank were "misplaced" by the machine shop years ago. The man that owned it graciously allowed me to purchase it to attemp a rescue. Now if I could just get my hands on dad's 3020... Oh yeah, mod # 265-12214, ser # 193453-452. Thanks in advance for any info!
