Nick Got the body of the water feed pump made tried to see how it fits in the frame, I can't get it to fit checked everything out and all seems OK can you post a pic of your loco showing how the water pump fits between the frames. Cheers :beer: Stew |
| NickG:
Stew, just seen this, been in workshop tonight, will take pic tomorrow. Thanks for the lubricator drawing. Nick |

Well her's the water feed pump body, I fabricated it up, but not yet soldered together, still got the inner poppet valves to do, the drawing calles for ball and spring valves, my poppet valve pump design fits inside the space envelope of the drawing valve And this is where its got to fit about an inch forward of this pic with the front between to motion frame:- according to the drg :scratch: Interested to see how Nick's pump fits I'm going to post the problem on the Model engineering forum to see if any one can come up with a solution. Puzzled Stew |

Stew, Took a few photos, unfortunately it's not quite as clean as yours :lol: Hope these help but if not, I will strip it out and take some more detailed ones. It's coming to bits anyway. From Top From underneath From what I can see there is a bracket with a cut out that bolts to a cross brace and the nut on your pump secures it to the pump. Nick |
| NickG:
Looking again at your pic it needs to be further towards the front of the engine. It looks like the gland nut is almost under that cross-brace on mine. I have just looked at the drawings and the gland nut does not secure the bracket to the pump. The bracket is 3/8" back from the end of the thread for the gland nut, which means the nut does infact sit under the motion plate. It has to be that far forward to clear the crank. Don't know which drawings you are working off but the electronic ones you sent me have it on, (sheet 5). Nick |
