WD Throttle Question

jbronson4079 · Nov 23, 2019

I finally got my WD running today that I recently inherited. The only weird thing is, that the throttle almost seems backwards. When it should be wide open and is at the bottom of the quadrant it is low idle and when at the top of the quadrant it is wide open. Could someone send me a picture of how all the linkage is supposed to be set up? I'm hoping they just had something set up backwards as it does not look right when looking at it.

Thanks!

Sounds like may have the wrong carburetor or at least the wrong throttle shaft in the carb

Carb is all stock. I believe it may be something in the magneto or throttle rods

Magnito has zero influence on how the throttle works. It has to be in the gov, the linkage, or the carb.

If you happen to have or stumble onto an Owners manual for a WD or WD45 there are pictures in there. Might be able to find this on-line ?? I can't visualize how someone could get it backwards. The rod running behind the distributor should pull rearwards when the hand throttle is pulled down. I just don't see how the bell crank above the right headlite could be bass-ackwards, but maybe....

Just bought a manual so I will check it out. I thought it was really weird as well and dont know how it would be backwards either. The throttle spring is definitely not the right spring but not sure how much of a difference it would make having the right one vs. the one that is on there. Once I get the manual I will compare and try to figure out how the hell they have it rigged up.

Been a while since I have looked at the throttle control linkage on my WD45. When I was doing so it was because I had no throttle control and found a triangle sort of looking part was not moving as it should. If the linkage on that triangle part where swapped out as in throttle part where the gov part should be and all it could cause that

Since no one has posted photos of theirs, how about you post photos of the linkage on yours, from end to end. Someone might be able to spot the problem.

I have attached the best picture I currently have

That triangle sort of looking part the gov rod and throttle rod hook to points backward on your tractor then it does on my WD45. I walked out to the machine shed just to be sure. So you need to flip it so the two hook up places point forward not backward of the tractor

As old posted. Like this, borrowed from the parts book.

Thanks guys. Plan on switching it around later this week. Will let you know how it goes

jbronson4079 · Nov 25, 2019

Would this be the correct spring I would need as well? I dont think the one on there right now is the right one.

Jim.ME · Nov 25, 2019

70220923 is the new AGCO number, so yes that is the right spring for key # 6.

jbronson4079 · Nov 25, 2019

Thank you!

Jim's parts picture shows it so much better ten I could explain if but maybe you can see how it makes a big difference as to how it works

jbronson4079 · Dec 5, 2019

Just thought I'd follow up on this guys. I changed that triangular bracket around and ordered the correct spring and the throttle is working great now. Thanks for all your help!

Jim.ME · Dec 5, 2019

Glad to hear it is working correctly, thanks for letting us know.

any tips or suggestions for cleaning this mildew off the top? It was
stored outside before I got it but want to get it off. Would just some
dawn soap and hot water get it cleaned up or should I use something
else?

old · Dec 5, 2019

Yes a good soap and water should clean it up but if it doesn't maybe some paint thinner on a rag

jbronson4079 · Dec 5, 2019

Perfect, Thanks
