Front Axles for 10 bolt Front Hubs-1.5 ton Australian Chevrolet Trucks 1940-1945

[Bob Carriere]

Hyatt bearings on Ebay...... ranging from 11.00 for just the race......to $20.00 and full bearings same Hyatt at $386 and a Timken at $650.......all the same number......

Pays to shop around.........ridiculous........

Would the answer related to the front spindle/hub bearings be located here on page 37 of the PDF?

For a brief moment after reading this, I thought that you could fit the spare HD hubs shown in the photos directly to my axle, but that would not be possible due to the fact that the king pins and spindles are larger in diameter...

Will be measuring the spindle on the spare axle with bicycle bearings......

Thanks for sharing.

[Bob Carriere]

My Outer bearing location on the spindle......0.848 factory 0.8427 to 32

Inner bearing location on the spindle.........1.413 factory 1.4051 to 56

That makes my spindle on the worn side but.......

....it is listed on page 34 as conventional..... heavy duty..... and my spare axle has the proverbial ball bearing bicycle bearings.

So it remains that the only other axle with larger spindle seems to be the COE which might have the roller bearings.....Hyatt Barrel roller.....

I have been working and learning by taking apart a spare front axle which according to the cast number on the I beam was made for 1946 to 51.....

I have yet to fully examine the actual axle of the targeted 1940 1 1/2 ton Chev that is still frozen hard to the ground with 12 to 18 inches of snow and ice around it.

[Philippe Jeanneau]

Agreed, almost 100% sure that the roller bearings we're after are only found on the COE models... So, the challenge would be to find one of these complete front axles and just slide it under our rigs!

The Chev 1533X2 trucks made in Canada especially for the LRDG had a wider and heavier Timken front axle - not sure what kind of bearings. They are quite hard to obtain in NZ and require wider front mudguards, so some replicas (including ours) use the standard beam axle with the bicycle bearings on the stub axle.

Hi Andrew

Nice to hear from you.....followed your build up with great interest....... you are to blame for putting this crazy idea in my mind to build one also.

I am working from 1940 GM master parts catalogue and specific GM 1940 parts lisitings including the Maple Leaf.

My biggest Handicap is that teh 1940 1 1/2 ton Civilian Chevrolet is still stuck in the Ice and snow......worst year in Ottawa since 110 years ago.

Meanwhile learning from a spare front axle I dragged in the barn....spare axle dates to 1946 to 51 according to casting numbers.

I have concerns that the long extension on the front HUB will put undue stress on the front bearing.....but the the manuals reminds me that the weak bicycle bearing was used well into the 1950s with a 2 1/2 ton capacity using duals.

Wish I would score a spare set of axles from a C15 Parts truck...... but no luck so far.

Am I to assume that your axle is a "Famous Timken Bearing axle" and if so could you share the cast raise part number from the front beam.....any photos????

Another two weeks and should be able to crawl under neath the 40 donot truck........currently in MUd, Mud Mud......

Last supplemental question.....what was the source of the dimension and design for your cargo box????

Thanks for the inspiration.
