Nice to see the "naked" 18 in. wheel........ with five holes.... were they running five bolts on the rear axle???? ....all the unmounted wheels I have seen are drilled for 10 holes.

Now that I have cornered a C15 from a Canadian MLU member my quest is greatly simplified.

This rim HAD 10 lug holes, but has been re-modified for a Maple Leaf by welding up 5 of the holes. The wheels for the 10 lug Chevrolet or the 5 lug Maple leaf trucks used the same basic blanks.

Also of note is that the 18" wheels are 8"wide, with the inner and outer halves being the same width. Again, the same blank is used for both halves, unlike the Canadian/UK 16" wheels which have a thick inner and thin outer half for a 6" width.

....can you imagine drilling bolt holes at the same station for 8 + hours......

Interesting google information..... and noticed that they were forge-stamped having been heated.......

does anybody know whether the same pre heating was used by GM and /or Kelsey Hayes in Canada ...... Oshawa workers where shown handling the parts...blanks and stamped parts in bare hands...... or was the picture staged??

Is it possible that the higher production capacity of GM Canada also punched out the center and bolt holes in the same operation.......???

Hi Hanno

Hi Philippe

What you have is a whole new and different type of adapter......... it has the CMP bolt pattern(8) ....similar to the C15 4x2 but much shallower....as in closer to the brake drum......... the C15 does nothave those smaller nuts showing and is bolted from behind like the civilian ones. The centre bearing cover is also unique being of a stamp metal screwed in to the hub,,,,,typically the bearing cover for the HD Timken bearing set up has a domed cover held by 4 small bolts/screws...... any idea what it came from????

Been very cold around here lately.... at night minus- 25 to -29C with a windchill factor of -35C.....very little snow so far but bitter cold.

Cheers

Is it possible that the hub in post #29 is a more modern (50s or 60s) one, maybe Bedford ?
