My serial numbers do not seem to agree with each other. Tractor # is WD157846, engine # looks like 17-58002-Z. Any ideas would help.

Your engine came either out of a 170 tractor or more likely a Gleaner E combine. If out of a combine, on the right side of the block, toward the back and near the bottom (just behind the dipstick) there will be a small plate covering a hole where the fuel pump would have gone on the combine. The suffix "Z" on the engine serial number tells you this engine was originally equipped with pistons giving it an 8.0:1 compression ratio. These engines were used in 170 tractors and Gleaner E combines. The model 17 engine in general was used starting with D17's through the 175. It's similar to the older engines found in the WD45, just a lot of internal improvements, more RPM, more power, etc. It's pretty much a bolt in changeover.

Thanks for the info. I think the tractor is a WD45 but not sure. Would this engine fit in a WD. The gear shift is curved on this tractor. Is there a way to tell the difference between the WD and the WD45.

WD production ended in 1953 at serial number 146606 and WD45 production began immediately with serial number 146607. There was no break in the serial numbers. From the serial numbers, your tractor is a WD45. Here are a few hints to tell if your tractor is a WD or a WD45:
1. Serial number is best
2. If it has a straight shifting lever, it's a WD.
3. If it's a curved shifting lever, could be either WD or WD45. The last year of production of the WD had the curved shifter. This is the constant mesh transmission instead of the earlier sliding gear transmission.
4. If equipped with original engine (can be easily changed however) the WD engine has a large steel plate on the right side covering the push rods. WD45 engine is just solid cast iron. WD engine serial number begins with "W" while engine serial number on a WD45 begins with "45".

Thanks again for the info. I bought this tractor a year ago at a FFA sale in Hillsboro,Ohio. I seem to find out something new about it every day. It is a really good running tractor. It has no problem plowing. There sure seems to be plenty of power. I think the $900.00 was well worth it.

One more set of questons. What would be the difference in horsepower between WD45 and the 170.Also, should i worry about to much stress on the tranny and rear end from the higher compression engine. I would like to pull this tractor at local shows. Any info would be appriciated.

Nebraska test #499 for the WD45 showed 43.21 Max. Belt HP. By the time the 170 was tested, they used PTO horsepower. Nebraska test #966 showed 54.12 Max. PTO HP for the 170 gas. I wouldn't worry too much about the transmission. The key is that you don't put a lot of extra weight on the tractor. Just weight it like you would for a WD45 and you shouldn't hurt the gears. If you up the hp and then add a lot of extra weight and then pull a really heavy load in a really slow gear, then you'd be asking for problems.
