Peter, Just found this photo on Station Road Steam: 9F CylinderLooks like there are two grub screws on top of the cylinder. John |

Hi John, Just took it aparts, there where no O-rings fitted, only some loctite to keep in steam tight. I cleaned everything and re fitted it with new loctite, now wait for it to dry  |

i was trying to see if the oil pump was working, but nothing came out, when taking the piping off, there was only oil comming out, en being sucked back in when turning the oil pump..... so i thought just take it of the engine to inspect it, but when releasing the nut on the underside, where the oil comes out, it broke  So i probably have to get a new one, but which one and where to get? Ofcoars oil will be important to keep everything lubricated so dont want to save money on a good oil pump.... |

SteamFittings still manufacture that type of lubricator but not with the right angle oil pipe connection as on the 9F: SteamFittingsSteamFittings were an offshoot of Modelworks but, unlike them, are still trading. John |

Hi Peter,
I've no experience of the Maidstone lubricators but I would imagine they would be ok. I usually make my own to the Jim Ewins design (like the one that is on your 9F). At least the ratchet ones have the right angle connection for the oil pipe that you need so would be an easier fit. The ratchets should be reliable so long as the ratchet wheels are decent quality and the pawls properly hardened.
It's hard to tell how the lubricator on your 9F is mounted. Is it just held on by the bottom fitting? That sort is really meant to be bolted down using the holes in the flanged base but the platform it sits on doesn't look wide enough for that.

Hi John,
It was fitted with the screw on the underside of the tank.
But i think they discovered it was turning so they put the most agressive loctite on the bottom to prevent it from turning.
Thats why i couldnt get it off the bracket in one peace, the complete housing cracked
I have ordered a new pump at my local model shop, so im sure i can return it if its not the correct one.
Thats the safest way for now, (not the cheapest....)

thank you, it was a lot of fun indeed to see it all working. The injectors where both working to, only there was still a big flow of water from the overflow. and they where not making the normal sound... also not when turning the water flow slowly off. But they start verry easy, open the water, turn the steam on, and done only half the water go's out from the overflow but you can see the water level go up. |

Hi Peter,
Re the injectors - you might find the steam valves are restricting the steam supply to the injectors which can cause the constant overflow that you describe.

Thanksss John, i will check this thank you so there need to be maximum steam flow? |

Hi Peter,
Yes, you need sufficient steam flow to suit the size of the injector. Sometimes the bore of the steam valve is too small to allow this. Another possibility is that the delivery clacks do not have sufficient lift for the balls and they are restricting the flow through the clacks. It's usual to allow more lift for the balls in clacks to be used with injectors than in those used for hand pumps and axle pumps.

Hi John,
Thank you, im not realy sure about my clacks, how can i check if they have enough lift?
Or maby to much? so the ball get in front of the ''exhaust port'' ?? could that happen?
i can imagine that there could be something wrong down there.
The injectors ar number 4 injectors, would it be helpfull to get a number 2 injector also?
So i have 2 different injectors to use with different boiler pressure?

hi Peter Just a note... I notice you say that both injectors are of the same size... should they not be of different sizes so that you have a larger pressure window for getting water in? or at least that's how I thought things were for loco's with two injectors... Don Young's Doncaster (only has injectors) which I'm building is certainly designed that way.Perhaps those more knowledgeable will pass comment... regards Pete |

Hi Peter, Re the ball lift in the clacks - Unscrew the top cap. With a depth gauge or digital caliper measure the distance from the top of the ball to the top of the clack body. Measure the depth of the cap that screws into the body and subtract this from your first measurement. That will give you the distance that the ball can lift. I'd suggest something like 1.5mm. I had this problem with my Helen Long when I first tested the injectors. I increased the lift on the clack balls and that cured it. Yes, it is possible for the ball to obstruct the outlet if the clack is badly designed. Pete - yes, I'd go for two different sized injectors as well. Mind you, I'm one of the old school and like axle pumps Drove a friends 5" V2 yesterday for about an hour. That has two injectors and no axle pump but only one was working, fortunately, very reliably! First time I drove the V2 it frightened the life out of me but I thoroughly enjoyed yesterday's run.

Ok thank you verry much John,
I will check this when im home.
Would it be ok for me to order a number 2 size injector, and from wich suplyer could it get the best quality?
I was not sure if the number 2 injector with a lower output, also says it has a lower operating pressure?
Peter
