Got a call from a friend last night. He has his grandfather's D-14 with loader and manual steering. Engine is very worn; not much power and lots of oil use. He has a line on a D-15 series II that supposedly runs good, won't stay in second or third gear, rear rims shot, and has power steering. He would like to put the D-15 engine and power steering in his D-14. I told him that I believe that the engine would bolt in, but that it runs faster than stock, so the tach wouldn't read correctly. Also D-15 is 12 volt and his 14 is 6 volt, so he would have to make some changes. Since the frame is wider on the D-15, the power steering probably couldn't be swapped. What do you guys think? TIA. dave

I like my D15SII with PS and all hydraulic loader; great combo.

I think the D14 tranny is the same as the D15. Maybe better to bolt up the rear of the D14 to the front of the D15 and move the loader to the D15?

Engine rebuild kits for the D14 (149 CI) engine are readily available; may be less hassle to rebuild the D14 engine.

The 15 PS will go in the 14. You will have to cut a notch in the side rail to make room for a nut on the side of the PS unit however.

If you used a flat head or hex socket plug, it wouldn't be necessary to notch the frame rail. Makes a much nicer looking job. FWIW Ed

The entire frame from the torque tube to the front gear box are 1 1/2" wide on the D15 then the D14. This includes the torque tube. Also on the D14 the side rails bolt on with 1/2" bolts and on the D15 they used 5/8" bolts at the torque tube. The 160 engine should bolt up ok. If you remove the plate where the PS ram goes into the gear box and check if the second gear ( idler) is there. According to the parts book, they used one gear box for PS and a different one for non-PS. However, I talked to someone at a show who said he put PS on a non-PS D14 by just adding the parts to the gear box. He said the idler gear (228640) was in it. I don't see any serial # breaks in the parts books on a change to the gear box. Bob

Greg has the right idea. I have a D-14 transmission and rear end in a D-15 diesel.

It bolted up and works with no problems. I think that this is your simplest solution.
