Reference is made to post 55: 1500 gallons of water weights 12,450 pounds. As I assume you are desiring to run the truck on unimproved roads, is it overloaded ? Pump, hose, tools plus weight of water ? Most tanks, if they are baffled at all, are only front to back not side to side. NFPA reports the biggest cause of LLOD involving tankers are roll overs. Be guided accordingly.
Post 56: Army TM on rigging ( I don't know the TM #) gives ratio of cable to sheave as 12:1. Such a block would haver a sheave wide enough to accommodate the cable and enough strength in the side plates and hook to carry to load such a cable would bring to bear. Check NSNs in appendices of -10 manual for block authorized for a 5 ton truck.
Reference post 62: pics of winches with exposed dog clutches are derived form WW2 CCKWs and M37 Dodges. Note grease points of capstans and sliding clutches. Idea is to illustrate that these things cannot be forced into engagement by applying a cheater pipe to the clutch operating handle. See previous post about untrained personnel using unauthorized tools. Move capstan to align opposing clutch dogs. With a M 54 where the parts are concealed, this is a touchy feely operation.
I was told it is 1500. That may be a approximent number. It is the tank from the chasis of our previous tanker. There are no pumps. it carries 1 fold out dump tank and one hydrant hose. Its not baffled. Yes, we are ALL aware of that danger. And have been trained accordingly.
Just as a comparison, our pumper tanker fire truck is 1500 gal. and is a single axle. Which is pretty standard fire truck equipment.
The cheater bar reference was to the use of a 3/4 ratchet with a cheater bar attached to the drum input shaft by used of an adapter to release the tension in the cable tangle.
As said , that was not required. The input shaft turned easily.
The following discussions was on getting the clutch dogs to reengage. There was mostly agreement with some. "No .. do this first, then that" You have addressed that.
I have been given several excellent video links and manual references.
The snatch block we have is for 1/2 cable. How ever its has a 4.5 in pulley. As it was rated for 1/2 cable the assumtion was made that it complied with being rated for 1/2 cable in all regards. If 1/2 cable is supposed to have a 6 in pulley then something is amiss. It was bought from a US rigging company.
The lesson has been learned.
This afternoon there will be two or more people to address the issue. It will not take long to see if all the info is valid.
I will give a update.
