Front rims on suburbans

Recommended Posts

RedRanger

I have a 401.  The front rims are both different upon inspection.
Both are 8 inch and same width.  Both have the same offsets.
Both are wheel horse rims and have the two holes for bolt on weights.
But, one rim has the grease zerk and valve stem on the outside and the other rim has them both on the inside.
(no you can't just flip one wheel around as the inner hub length is longer than the outer hub length.)
The second difference is the shape of the "dish" or "bubble" in the center of the wheel.
One has a more pronounced hump in the center of the rim.
It is obvious that one of them is not correct to the tractor.

From what I can tell, it looks like these early models had the zerk and valve stem on the outside.
I obviously have rims from two different years or two different models.
Where the front rims different from year to year?  
Anyone have knowledge of what rims were used in what years or what my odd rim might be from?
Is there a way to ID these?

Here is the "correct" one.  I can't find a picture of the other one at this time though.  The other one looks very close, just the zerk and tube are on the other side of the wheel and the bulge in the center is a different shape.

That's the exact rim I have on my 400. Odd that the stem and zerk are on the outside but I've seen that on others as well. Maybe the wheel supplier ?????

Nothing wrong with them that way Craig but they are backwards. The longer hub goes to the inside putting the stem and zerk on the outside. I was at odds with myself as to which way to put them on my 400 and finally multiple vintage pictures in the Horses Mouth book made it clear. :)

Putting the longer offset on the inside seems to line them up with the rear tires better too.

Better pictures of the wheels on my 401.
The first is the one that I believe is correct.
Notice the zerk and stem on the outside/shorter center section and the "dish/hump" in the center stops before it gets to the two weight holes.

The other rim, has no zerk or stem on the outside and the center hump extends all the way out to the bolt holes.  Any idea what model this is from?

The factory original "metal wheels" had the zerk fittings on the outside and were 1.62" hubs, and after '63 the wheels had the zerks on the inside and had 1.5" hubs.  The original 1 5/8" wheels not last in areas with salt and rusted quickly, the only replacement wheels after '63 were the 1.5" wheels.

(that's why the repro flex hub caps we make are shorter in depth, 1", to easily fit on the 1.62" hubs up to their outside zerk fittings).  To me, your zerk-wheel doesn't look standard 'Wheel Horse', I think the zerks were always on the Hub stem (the first original WH front wheels were actually standard wheel barrow wheels).

That zerk is on the hub stem.  It's a 90 degree zerk.

      The RJ58 was the big hit for spectators this year at my local festivals here in Carroll County OH. 
      the children loved getting their pictures sitting on it, then they discovered the bicycle horn under the steering wheel. It’s always a joy even in parades. Just love showing off part of my collection every year and hearing all the stories from those that had WH in their lives at one time. Can hardly wait to get to retirement so I can get some of my other models back to their glory in working order and be able to attend other shows/festivals throughout the year. My fellow tractor enthusiasts always know when a spectacular starts asking about WH, they point in my direction. I study up on the history of the different models and always intrigue those that didn’t know much about how WH came to be. This website is one place that has helped me learn so much about the WH history and I thank you for sharing your knowledge that I am able to pass on to keep WH alive and well.

      Are new throttle and choke cables available for 1960 suburban? Last thing I need on this resto. Old ones are pretty rusty. Thank you.

      A couple weeks back I picked up this nice, original 551. Since then I just gave it a quick bath and swapped the rims and tires with an extra set of Cubs that were sitting in my shed. This is the first electric-start Burb I've ever had and I'm really digging the turn-key. No plans to restore. It's just a nice driver with the right patina.
