Allis Chalmers W Speed Control (Grader)

[Burl C]

Rebuilding the clubs Allis Chalmers W Speed Patrol, and can not find the purpose of, and attachment point of the two springs (part 32) shown in the pictures. The photo was grabbed off of the internet, and I've scoured the net for a picture that would show the attachment point for the springs. No success. Any help is appreciated.

Well if you run one much which I have done for decades you will find those spring help lift the blade back up when you turn the big hand wheels. If the spring is off you sure as heck notice it is off.

Thanks, old. I don't have the blade at my house, so didn't even think to look for attachment points on it. In hindsight, that makes sense. Curious that the parts manual didn't show that. The search will be on for a set of springs, I imagine they'll be hard to find, but that's part of the fun. Here's a link to photo's of my rebuild progress, if you click the images, you can see the comments on what's going on. I update regularly or club members to see. Thanks again.

I've had the W Speed Patrol I have for 30 plus years now. I did switch engines in it years ago when I picked up a WD that had a rebuilt engine nd it was a big improvement over the wore out WD45 engine that was in it

Can't say for sure, but thinking I've seen similar size spring on used on some of AC's manual lift cultivators?

Part number from A/C is 603378. If nothing else I could maybe measure how long they are and how big around they are and how thick they are

Hey, Old. Thanks for offering to measure your springs for me. I've not been able to cross that part, and tried several dealers and they have had no luck either. With your measurements I should be able to get a couple made. Probably cost a bit, but that's part of the hobby.
Talk to you later. Burl

Spring is 23 inches long. Diameter of the coil part is 1.5 inches and the thickness if the wire the spring is made up of is 1.8 inch. I did have to raise the blade on my W Speed patrol to do the measure LOL
