Hi Dave
As Keith said "heavy and bloody heavy" which is of course correct but, allow me to quantify that a little bit. Having taken three of these beasties apart working by myself I have had to use lifting tools most commonly the Jib Crane in my shop with a chain fall attached. The chain fall I use is rated at 900Lbs which basically limits out at what a 160Lbs man can pull down on the chain to raise the hook.
With this in mind most logical component units can be hoisted. Example rear axle assembly with tires (no springs) for a HUP. Front or Rear axle assembly no springs or wheels for C60. In the C60 case the runflat tire and wheel are in the 350+lbs per wheel. Engine and transmission under 900Lbs. Chassis for HUP easy, C60L stripped right at 900Lbs limit. I think that these group weights was probably pretty typical and probably for the reason Keith alludes max weight that "four blokes" can lift.
Exceptions to this are stripped Body HUP probably goes 1500Lbs as my jib crane and chainfall could just lift one end of the HUP body with the other end supported easily by 1000Lbs lift arm on the other truck. I suspect that assembled Pattern 13 cab with nose and doors will probably be in the same 1500Lbs range.
If you want to get a idea of what and how I was lifting things take a look at this Youtube video of pulling and installing the engine on Pat 13 C60S. The purpose of the time lapse video was time and motion study on one man pulling the engine and installing engine. Watch the time to pull the nose and engine and then how long it takes to reinstall think it is 5 hours to remove and 5 days to install.

The install time got extended out because of delay in getting parts so it ran out over a much longer time the video is made up of individual shots the camera took a picture every minute or so that it saw motion, so the jumps between shots meant I was probably not in the shop.
Hope this information is of some use.
