M812 front end swap

[Doubled]

I have a M812 (year unknown) that needs a front end replaced. Will a M818 1971 work as a replacement?

as long as its a cummins powered m809 series, as far as I know, they are all alike. Please, somebody correct me if I have given bad information.

There may be some differences since the hubs were made to hold the bigger tires used on the bridge trucks. Or they may have just put some kind of adaptor on a regular 5 ton axle.

Thanks for the info!

We have an M812 and the rear axles and dogbones are different but the front appears to be a standard 5 ton with wheel spacers. The local camp is scrapping 4 900 series bridge trucks but they use full air brakes instead of air/hyd.

The 800 series front axels hve remained unchanged since the fiveton trucks wer gassers. In seeing all the front end failures,It seems to me that the cause is the excess weight of the Cummins engines. Especially, since they were never beefed up since the early days. We just changed the front axel in the M816 from an 813 take out. It bolted right in. I suspect that the hubs and drums would be different if you swap an axel from a bridge truck. Just use your old drums and hubs. I'd pay attention to inspecting the bearings and repack them when you have it apart just to be on the safe side.

I see where my mistake occurred. When I think of a "front end", it is usually sheet metal, not the front axle.
Its all good!
