| You need the ring and pinion from a WD-45 diesel or an OLD D-17.....newer D-17's were just a little different in main shaft length. |

| The old WD's are a sliding gear style transmission with roller bearings on the countershaft. The ring and pinion from a WD-45 or D-17 will NOT work in that transmission housing. It is simply different and none of the gears interchange. Now, if you wanted to try and machine the housing for Timken bearings on the countershaft, and graft a WD-45 transmission inside it then?? maybe, but why would you go to all that work when you could change the whole rear end as-is?? |

I agree with doctor Allis, you'd be better off to just unbolt everything from the bell housing back and replace it with either a wd45 or wd45 diesel rearend. I unbolted my frame rails and the six bolts from the bell housing, and it was as simple as sliding the rearend out, switching tires, and sliding the new rearend in. ------------- 1950 B, 1952 pulling wd, and 1954 wd45 |

| Find you a diesel rearend and save yourself a whole bunch of time and headache. Me and a friend had mine swapped in no time. Rearends aren't plentiful but I'd check with Tony C and he could probably hunt you up one. |

I'm a little late to this party, but I have a question. What would be the advantage to swapping a WD45 rear-end onto a WD? I ask because I will soon have a 45 without an engine. I have a WD with a decent eng. Besides changing from straight cut to helical cut gearing, is there another reason? ------------- 1955 WD45 S#205467, 190XT #6652 DXT |

| depends on the HP level. the helical gear transmission is stronger. The WD transmission has a low gear of 2.5 MPH and the WD-45 is 2.3 MPH. Doesn't sound like much, but when you use 38 inch tires the difference becomes more pronounced....faster is better if you must use low gear, as long as you have enough engine, that is. Second gear and third gear speeds are identical between the two transmissions. |
