Grand Union tanks are also rather iceberg-like. What you can see is a triangular box in each of the foreward corners of the engine room; what you can't see, until you take the floor up, is the foot deep coffin shaped tanks that extend back as far as the rear bulkhead. Now, these do come out. In fact, they must be intended to come out, and have come out, in the past as one of them is marked 'Chertsey'. But they do not come out with much room to spare.
First thing we had to do was close the cock on each tank and remove the balance pipe. Then we had to disconnect the breathers that go through the foreward bulkhead on each side. Now who forgot to bring the BSP spanners? OK, that accomplished with he trusty slip-jointed pliers (now there's a miracle of design). One further hitch was that at some point in the recent past, a vey nice, robust, external filler had been fitted. Normally, you'd fill your G.U. tanks via a hole in the top of the triangular bit, through the side hatches; for some reason this had been adapted to fill from the outside with a big solid pipe bolted onto the top of the right hand tank. To undo this we needed a 1/4" Whitworth spanner (remember this; it's significant) which we didn't have. After trying everything else in the box, Jim made one by grinding down a crappy old one and got the flange off. He then 'horsed' the tank from under the filler pipe, but it failed to clear it by about half an inch. At this point it was decided that I would be much better off reverting to the traditional method of oiling up, and the hefty pipe was ground off (outer trip hazard filler cap and surround to follow).
All in all then, another excellent day's work. Plus I put some potatoes in the oven at quarter to eight this morning and they were ready in time for lunch, and at suppertime I successfully fried some bacon.
By-eck your cracking on now, well done.
ReplyDeleteTalking whitworth bolts, on our tank I found the bolts to be full 1/2in whit. Which makes them pre-war, very rare nowadays. so find some try keep them.
