Hi Greg, Thanks for the offer. We plan to visit your neck of the woods when the ground at the S&P Museum can support truck traffic. I intend to move my C15 Dump Truck (which is for sale) to Bob's barn. If it does not sell, it will be stripped down for parts.

We will give plenty of notice of the visit so that we can figure where to deposit your engine which I hope is still in the back of the dump. As well, we are on the scrounge for cleaning rags, cover alls etc...

Guy Vapeur is looking for some good modern modular tent centers. He peeks in on this forum every so often and he may PM you with details.

Regards to the family and neighbours! Rob

PS - I updated the first post in this thread...call it a late summer sitrep.

.....hoping to see you soon.

Looking at the RF stamping and playing with contrast adjustment I would say the DUNLOP 0 stands for 0 degrees as opposed to the otherstyle rims which is listed as 5 degrees......... and the flat 0 degree rims is what you have on the HUP.

Comments anyone...?

Maybe the RF stands for "Real Fast"...

The design record lists two types of 16" rim. One is listed for 9.25x16 (HUP)tires, the other for 9.00x16 and 10.50x16.
Both are DND designs (not K-H), and are listed as having 6 inch width and 10.827 inch mounting bolt circle. (They could be K-H made and DND designed)
The one for 9.25x16 tires weighs 46 pounds per wheel, has a 5 degree rim taper, 1-1/8 inch flange height and 0.5625 inch centerline offset.
The other type for all other CMPs weighs 67 pounds per wheel, has a 1-1/2 degree rim taper, 1-1/2 inch flange height and 0.250 inch centerline offset.
The weight difference seems to be mainly because the HUP rims are made from thinner stock. It is probably possible to mix HUP and "other" CMP wheel halves and have a driveable wheel, but due to the different geometyr of the rim and the different offset I don't hink I want to make the experiment to prove it works or otherwise. My first explanation for the different offset was that the tires were the early equivalent of "wide profile", then i thought again (10.5 is wider than 9.25) (even stranger, the 9.00 cross-country tires had a wider section than the 9.25 ones - I don't understand).

Comments on Bob's theory - anything could be possible on a one-off prototype basis, but would they create a die to mark a one-off rim? Most HUP rims are 5 degree taper, not 0, that's why I think their tires are less evil to remove from the rim.
The only rims listed as Dunlop designed (as opposed to manufactured) are in the 5.00x18 size for 7.00x18 tires which had comparatively narrow .75 inch flange width, 3 degree rim taper and a bolt circle different than all CMPs but closest to the C8's rims for the 9x13 tire.

They were stamped by hand.... the RF is not even


DUNLOP looks like one stamp the 0 is not lined up and the HA 900 was stamped individually....... my conclusion is one of a kind or very low production.....

The question on my mind is when did they start making 6 bolt rims.... for the HUP or did they exist for earlier C8.....? or are all C8 13 inch rims???

The Prototype rims in question are definitely of lighter gauge steel than any other HUP wheel that Rob has worked on......

Curious!!!!!

Bob,

The Ford Lynx takes the same 6 bolt 16" rim as the C8A Heavy Utility.

Hi Brian

When did the Lynx came into production.....??? The rims Rob took off the Prototype were exceptionaly light weight and flimsy.... I know they were rusted but when we worked on them the center flat section was really flexing like sheet metal........ Surely the Lynx must have been using a thick walled rim in view of the extra weight it carried.

Strange.

After the antique gold discovery in ENgland I bet ROb will be taking the doors skins apart to see if any treasures can't be found.
