I'm getting further along on my WD45 engine build. I'm fixing or replacing everything. I'm gonna be using a NOS Agco D17 piston kit. Also going to get D17 spring. Should I have anything done to the camshaft to help it anymore? What about carb..can I do anything to it or change to another one to help it? This is still a work tractor but anything that will help performance and efficiency I'm willing to do it. I just got my head back from machine shop today. Still have to get block work done when I save some more money. Maybe I'll have it running in November.

Well of course I'm putting in new cam bearings lol. :) I have $3000 into this thing. Polly gonna have close to $4500 when done. No stone being left unturned on this one...whatever it needs to be right it's getting it.
Steve is that all that needs to be changed to make it work? I'm not going to convert to full flow oiling. Can the WD45 cam be ground to 175 specs? Edited by 79fordblake - 13 Aug 2016 at 3:59am |

You said that D17 pistons are going back inside, are they 7.2 to 1 or 8.0 to 1, your WD45 cam is the same grind as used in all D17 and 170 tractors and some D17's used the same carb as your 45 so they will both will work fine with 7.2 or 8.0 to one, If you go to the D17 spring it will not help much for PTO work because you can't run her at wide open as the PTO will turn to fast, if you are not using the PTO or most work is using the draw bar then use the D17 spring. I'd clean the inside of the air clearer good and it will supply all the air OK. You can have your WD45 cam built up and re-ground to 175 spec. if you go with a re-ground or new cam replace the lifters too, or have the old one's reground.
Sounds like you are going at this right. |

3 WD45's with power steering,G,D15 fork lift,D19, W-Speed Patrol, "A" Gleaner with a 330 corn head,"66" combine,roto-baler, and lots of Snap Coupler implements to make them work for their keep.

They are 7.2 pistons. My cam looks to be in great shape. I guess it's not much of a gain? I do alot of PTO work so it sounds like the D17 spring is a no. But I may get a new WD45 one I'm sure its not as strong as it once was. Yep I was also going to clean the air cleaner very good. Thanks for the tips. Looks like maybe I should just leave cam and carb alone. The carb will be rebuilt as well.

You can use the 175 cam it will gain more HP over the D17/170, and the D17 spring too just run the engine down to the right RPM for PTO work, find the right RPM and mark the the right spot.

My opinion question is will the 175 cam help at the lower WD45 or not do much unless running high RPM's? I'm thinking in car terms where a cam is matched to a desired RPM range. Maybe we're so low and close with RPM's here that that train of though doesn't work here.
I wouldn't put a D17 spring in if you're going to use the PTO. |

Ok so if I get a 175 camshaft I need to change out gear on my oil pump? Do I use my same cam gear? Plus have cam followers resurfaced or replaced. I wonder how much it will cost to regrind my cam to 175 specs?

OK, let's put this 175 cam thing to bed;lol it will not be that much help on HP if you stay at stock RPM's for the WD45, and if all you have for pistons is the 7.2 to 1 going to the 175 cam and D17 spring it will not be much help if you are running the Wd45 under the higher RPM's of the D17 to stay at the lower RPM's the Wd45 engine run's at for 540 RPM. If you are looking for the highest HP out of the WD45 engine and PTO speed is not a problem then go big and high with pistons, cam and spring, carb change the air cleaner, drill the three 3/8" head studs out to 7/16" drill the manifold studs out to 7/16" install a D17/170/175 manifold, D17/170/175 muffler and find an early "A" Gleaner carb change the throttle shaft or weld the lever on the A Gleaner carb to work with your Wd45 governor. weld a reinforcement to the left side of the block, line bore the mains in the WD45 block so a D17 crank shaft will fit and you will have a big dog. lmao

Lol ok Don you answered my question. I'm not even going to bother with it. I don't really want to turn the engine faster or make any major mods. Just a good dead reliable stock engine to last 60yrs. Lol.

Now you are thinking the right way. It will have more power over stock and last for years to come. ![]() ![]() ![]() ![]() And I have not tried to install a D17 crank in aWD45 block, It might be one big job to do. That list short list I posted above was most of the changes that happened to the 226 to get it up to the HP 175's have from the WD45 and stay in one piece. Now if you can find all the parts to build a early 180 gas with the 226 engines you will have the biggest dog with AC parts inside. And just a FYI the 175 camshafts are on back-order.

Barney Taylor can grind cams to 175 specs. And I suppose a lot of other people. Heck, I bet Pankey has 10 or so under his bed! Just ask him! Lol!!!!

Dave back when the IHC 1460 combines came out I got a call from a 50 year old big at the time farmer I think he farmed about 1500 acres, OK I'll get back to the story he called to see if I'd turn is fuel pump up, I asked him if the combine is still under warranty well yes it is, I told him that will void the warranty and I heard all about just how short on horse power and he will find someone that can turn it up, well back then I was running my own farm shop and a dollar was all I was looking for so out the door in the shop truck and to the field I went the new 1460 combine was sitting hood up all ready for me to do my HP turn-up job, I had been doing a-lot of AB 100 pumps on them IHC tractors and had a good best guess on the turning the fuel up, he made a one round stopped and said that's better but I need more HP well what the heII I gave him a lot more fuel and it looked like the old pulling tractor of the time, turbo lag and all intell the engine got over about 1200 and then it came to life and he was in good wheat in the mud what a rear wheel asst and tracks on the front pushing mud and cutting ruts three foot deep and the engine was still turning 2450 RPM's and the black was covering the back of the combine I told him I needed to turn it down some we he said to leave it alone, OK I did and he had to stop after one maybe two rounds and let it cool down. Yes the engine let go in a grand way inside parts laying on the outside of the engine and even a part of one rod in the grain tank. I had done a lot of 1440/1460/1480 combines and was good at removing the steel seals on the pumps and had a lot of them in my tool box (I might still have one or two it there) I turned the fuel pump back down the same number of turns that it was setup to installed a seal and shot some red paint over the pump Good old IHC replaced the engine but reinstalled the old pump on it so it was sent to the pump shop and set back to spec's. All he needed as more and that cost him having someone cut his wheat as his new combine sat in the shop getting repaired. |

If a camshaft has a lot of hours on it then having it ground to specks is a good thing if you have any questions. If you have the desire to get a few more rpm's you can send the camshaft to a place that does up grades along with piston diameter, stroke, desired rpm and they will grind it to your wants or needs. I used Crane cam and was pleased. Plenty of other places that can computer grind them also.
