Surveyor Posted April 2, 2023 Share Posted April 2, 2023 Got this to help a friend The tap only partially turns to on. Apart from dismantling from the tank, any suggestions. I am going to put it vertical and "wiggle" the tap to see if anything jammed. Any other suggestions would be appreciated Richard Quote Link to comment Share on other sites More sharing options...
fv1609 Posted April 2, 2023 Share Posted April 2, 2023 WCP is covered in EMER ENGINEERING & MISCELLANEOUS D 410 Data Summary. Apr.1973 D 412 Technical Description, Unit, Field & Base Repairs. Jul.1987 D 417 Mod to fit all ¾ ton cargo trailers. Mod.Instr.No.1. Apr.1975 Unforunately repairs only cover the tank which is to be repaired according to EMER WORKSHOPS O 370. "Components other than the polythene tank are to be repaired by replacement" Although there is a list of components none of them are VAOS or NATO codified it just lists MEXE Drawing Numbers. The UHB AC No.60377 Part 2 gives no help for your probem. The EMER states it should always be stored with the outlet valve open. All I can suggest is saturation with release oil then a gentle tap one way & then the other to gradually build up a bit of movement. Perhaps first a gentle application of hair dryer hot air. 1 Quote Link to comment Share on other sites More sharing options...
Surveyor Posted April 2, 2023 Author Share Posted April 2, 2023 Many thanks, it's not an urgent job but need to get done before summer. I was putting release oil aside for the moment as thinking of tainting the water. Will keep posted if I get it sorted Quote Link to comment Share on other sites More sharing options...
fv1609 Posted April 2, 2023 Share Posted April 2, 2023 I think you would be doing quite a bit of flushing through before drinking anything from it. But there are non-toxic & non-tasting lubricants available for use with machinery in the food industry. 1 Quote Link to comment Share on other sites More sharing options...
Surveyor Posted April 2, 2023 Author Share Posted April 2, 2023 Yes it's more to carry water for plants and animals. I suppose next question is apart from regularly moving the tap, what to lubricate the tap with? Quote Link to comment Share on other sites More sharing options...
fv1609 Posted April 2, 2023 Share Posted April 2, 2023 The tap plug is nylon coated & the sealing rings are of nitrile rubber. The maintennance instruction requires no lubricant just to "Regularly examine equipment and accessories and report any damage." Although the WCP was intended to be used in a 3/4 ton trailer, it was also intended to be fitted into a 3/4 ton Rover. 1 Quote Link to comment Share on other sites More sharing options...
Surveyor Posted April 2, 2023 Author Share Posted April 2, 2023 Many thanks for this, I think I need to get good weather and have a look A thought does occur that these elements may be broken which is causing the issue Will have another look at it next weekend weather permitting I have a Penman for it once working Quote Link to comment Share on other sites More sharing options...
fv1609 Posted April 2, 2023 Share Posted April 2, 2023 Yes the clever thing about WCP is that they are so versatile that one or more can convert a GS truck or trailer into a water bowser, without having to have single purpose vehicles & trailers that can fulfil no other role. 1 Quote Link to comment Share on other sites More sharing options...

Jayvee2003 Posted April 5, 2023 Share Posted April 5, 2023 Doesn't the valve just un-bolt from the outlet of the tank? It looks like a Saunders ball valve. Not sure of the size of the valve in your case, but here's a link to an 1.1/2" one on-line and a table of sizes.

robin craig Posted April 5, 2023 Share Posted April 5, 2023 Haynes silicone grease is available in spray and squeezy tube and is food grade and great stuff, available on Amazon. Nothing like it that I have found as yet as I haven't needed to look after I found it.... use it on water systems for o rings and various lubrication issues . My two cents worth.

fv1609 Posted April 5, 2023 Share Posted April 5, 2023 Yes, that is a useful diagram, it comes from the UHB for the winterisation kit to show the existing system before fitting the additional bits for the insulation jacket. There was also an immersion heater kit. I can't remember how I found out but I think there were only 3 full kits supplied to the Army & 7 to the RAF.

Many thanks again, I will have a look tomorrow, daft thought was to try first by putting it upright and waggle the handle to see if it's a bit of something and let gravity see if it will loosen. If not spanner time, will post what I find Quote Link to comment Share on other sites More sharing options...
Surveyor Posted April 7, 2023 Author Share Posted April 7, 2023 First stage done, it looks like WD40 time as the pins for the handle have been sheared off. Need to find my tin Quote Link to comment Share on other sites More sharing options...
