I recently acquired what i think is an A-C WD that i would like to restore. Looking up the serial number 235540 i see that this should be the serial number of a WD 45 from 1957 where the Serial #"s start at 230295. ALso this tractor has factory wide front and power steering, distributor and coil (not magneto). The decal on the radiator is toward the bottom and WD is clearly visible. Im confused. Any suggestions?

Also, another clue would be the wide front end. If the plate on the front of the pedistal has 4 bolts it is a WD45 built after 1953. Of course some one could have put an older widefront on but with the power steering, the curved shift lever and the serial number I would disregard the decal.

Most of what you post indicates a WD45- serial number- if it is indeed from the differential, engine number, factory PS, etc. 1956 was factory PS or later. Decals don't mean squat-anyone can slap them on. If the engine number starts with a 45-, it is a WD45 engine. If the engine does not have a cover on the right side, it is a WD45 engine. All WD45s had the battery ignition instead of the magneto.

Keep in mind that the WD and WD45 both used the same grille/radiator shroud. The original may have gotten damaged and was replaced with one from a WD. Simple, but probably what happened. Also, the rear end might have been swapped out. Not as likely, but also possible on a 60+ year old tractor.

Well i did some checking, there isnt any removable cover to the rear of the distributor and the shift lever is curved. Also i check the casting number or engine serial number im not sure which it is im havng trouble trying to figure it out but it starts with a 45-. Does that mean that this was cast a WD 45 block? Also i have the head removed because the engine was stuck but i did some measuring and it appears that they stroke is approx. 4.5 inches which means that it would be a WD45 so it appears that the radiator and grille have been replaced. Thank you for your input!!! Ill have to post some pictures of it. I

Sounds to me like you have a WD45 that the grille was replaced on at some point in the past!

If you have the serial number correct, it is a WD-45. Other features are that all 45's have a curved shift lever (some late WD's do as well so it isn't an absolute feature). Behind the distributor on the right side of the engine is a removeable metal plate (or cover) on WD's. WD-45's do not have this cover (the block is smooth).
Good luck!
