Guys: Has anyone here used a 226 power unit engine in a D17 Series IV tractor. Any modifications to contend with, I am assuming the power unit is a direct bolt in replacement, but have not done this conversion. Any comments or thoughts would be great. Thank-you...Orangeman PS - Is the radiator in the power unit the same as in the D17 tractor? Reason I ask is that some of the smaller AC power units like the 149 the radiators are not the same as in the tractor.

| The rad in my g226 power unit is not the same rad as a 17, and as for putting the engine in a 17 I dont know why it wouldnt work, but I would think if you had a g226 power unit you should be able to sell it and make enough to put a little cash in your pocket and buy a gleaner E engine to put in your 17 |

| It needs to be a G-226 power unit, not a W-226 power unit. |

Hello Dr. Allis: Can you give me some tip on the difference between the G and W 226 power unit models. Thank-you Orangeman

| W-226 is commonly used in the WD45 application. The G226 was first used in the D17 application and later on the 170-175 and E and E3 Gleaner combines. Look at the serial number behind the carb air inlet hose stamped on the block. If it says 45- XXXXXXX it's a WD45 engine. If it says 17-XXXXXX it's a D17 engine. There are also several other ways to ID which one it is. |

Ok guys I did positively identify that it is a W-226 power unit as it starts with 45 xxxxx on the block. Question - Can the W-226 go into a WC tractor without mods? Thank you for any comments or help. Orangeman

Are you saying a W226 engine won't bolt up in place of a G226? I always thought you could bolt a 17 engine in a WC and visa versa. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

As far as bolting in, both G and W 226 engines are the same. The G 226 has a rib cast into the block on both sides just above the oil pan and also has 3" mains instead of 2.5" so is a more robust engine. ------------- Nothing is impossible if it is properly financed |

Calvin and Charlie: Thanks for the info. That is quite a jump from 2.5 to 3" mains. We have a few WC around our area that could use a donor engine, so was thinking the W-226 could go in place of the old WC engine. When did Allis start to equip the 226 block with a Dry element air cleaner?
