1951 F-5 Marmon-Herrington
 
3 Attachment(s)
Making some progress on the 1951 F-5 M-H project. Just to refresh the memories, this project started as a former snow plow from Mammoth Mountain ski resort, missing all the snow plow goodies. Truck came with Firestone 20 x 6.0 Max Tire Size 8.25, split rims. In CA I could find the tires, but nobody wants to touch the "Widow Makers". I tried to "out smart" the truck, and bought some Firestone 19.5 x 6.00, but the dish on the rims is too shallow for the front brake drum. Once again, my front stud was too short, really! Any ideas on how to solve the TRUCK RIM issue?

Hmmm, looks like you have the SnoGo type spacers still on the front. The Budd type "inner cap nuts", normally used only on the rear, can be seen on the front and is the clue that the spacers are/might be mounted. You might post a picture of the hub and drum if you think I'm wrong. I've not heard of 19.5s not clearing M-H front or rear drums so there is something irregular going on I think. You look like you are making great progress.

Edit - is it camera angle or are the two pictured wheels side by side different? Stu

Hey Stu, The first photo shows the 20" on the truck with standard front lug nuts, the second shows the 19.5" with a spacer behind them. That's why the rear lug styles are on the front, due to the spacers. The third, is the Firestone two-piece 20" next to the Firestone single-piece 19.5". I have two Budd 19.5" maybe they would work on the front? Thx, Jerry

Have you tried the 19.5s without the spacers up front? I think I recall Chuck saying that the SnoGo trucks added the front spacers to move the wheel mounting surfaces outward so that the front and rear wheels tracked together. Running without spacers would make it like a more traditional R5-4 M-H. Stu

That looked like a rare SnoGo to me too but I'm no expert. I wonder is the remaining snow blower parts are lying behind some workshop at Mammouth Mountain. Might be worth the 5 hour drive from San Dimas to check?

Hey Stu, Could I ask for your help again? I pulled the front wheels off and discovered the front drums are stamped 3219-L-1728, and the initials G.F. Are these the correct drums? The back of the 19.5 rims are hitting the outer rim of the brake drum, making the studs too short. I have tried Budd and Firestone rims with same problem. This is just baffled me... Thx, Jerry

Boy, those numbers don’t follow Ford’s numbering sequence, nor any M-H sequence I’ve seen. The numbers could just be casting numbers that have no part number connection, or could be genetic drums that are not to O.E.M specification but still work. I’d suggest seeing what Chuck Mantiglia has to say about this. If those drums work you may just have to reconsider the 19.5s and go with either 22.5s or a set of locking side ring 20s. Stu

Hey Stu, I appreciate the effort. I'll try calling Chuck during the week and hopefully he can offer some new info on this situation. Thx, Jerry

Hey Stu, from what you and others told me about the Firestone 19.5 rims fitting on other M-H brake drums, I broke out the tools today. I dismounted the rims and removed the spacer plate that a mechanic told me was needed. Well, I confirmed he was WRONG! With a little effort lining up the lug holes the Firestone 19.5" rims fit like a glove. Thanks again for your assistance. Jerry

I thought I was going crazy! Thanks for preserving my sanity. Stu
