Hydrostatic pump question

I am working on my gas/hydraulic which has a hydraulic pump connected to a "log splitter". I want to replace this setup with a hydrostatic pump but am having a lot of trouble getting information and specs, and figuring out what I need. My locomotive is a 7.5" SW1500 and has 2 hydraulic motors - one ...

Re: WTB Clippard MJQC-B4B4

Thanks Mike. I have always used the MJQC series because of the flexibility (1/8" tube connectors) and the high flow rate (14 scfm @ 100 psig ). Being able to get air pressure to the back of the train, and then release it quickly was important to me. The MQC-3 series, while cheaper, only move less th...

Re: WTB Clippard MJQC-B4B4

Tim - from everything I can find, Clippard is saying the entire MJQC line is discontinued. Do you have a supplier for the MJQC bulkheads? It would probably be a MJQC-PBB4, which would work. I Just need something in that same MJQC line. These fittings have a valve and a cap. The valve is used on the ...

WTB Clippard MJQC-B4B4

This part has been discontinued by Clippard and I have used them for my brake lines. I know it is a long shot, but would really like to hear if someone has some they could spare.

Please send me a PM with quantity and asking price.
Thanks.
Dale.

Allen Mogul Timing

I am still helping my friend with his Allen Mogul. Last problem was the sticky throttle, which was fixed thanks to this group. Now the timing... It was not running "true", so I found by backing the rod into the slide valve on the left side one and a half turns, I got it to run even and true and soun...

Re: Stiff throttle on Allen Mogul

All those who suggested to repack and lubricate the throttle rod have won the "door prize", which is my Thank You! I pulled the packing nut off and the throttle was smooth and easy, so I cleaned all the old packing out, rewrapped with graphite and added a drop of steam oil on the shaft. It worked li...

Re: Stiff throttle on Allen Mogul

Thanks to both Brew and RN for the help. I will pull the packing nut and hope that helps. Otherwise, armed with your information, I will open the steam dome! I will update my progress here.
Thanks

Re: Stiff throttle on Allen Mogul

The throttle is stiff when under steam. I tend to "jump" the locomotive when trying to start because the throttle is hard to pull so little, fine adjustments are hard. My Atlantic has a smokebox ball valve which is smooth and where I can do very fine adjustments. This is just a lot harder to do litt...

Stiff throttle on Allen Mogul

I am helping a friend with his Allen Mogul and the problem we are currently addressing is a very stiff throttle. The Mogul has a dome throttle with a packing nut on the back head. I am wondering if it could be just the packing nut, or if there could be something going on with the throttle in the dom...

Re: Hydraulic problem

Chris - Yes - we have spent a lot of time talking about just pulling the hydraulics and converting to all electric. That is an option, but if we are "close" and can do something fairly easy, then I would like to, for now, stick with this option. Bill - I would suspect you are correct - there is no a...

Re: Hydraulic problem

Chris - you are correct. There is no provision for a min rpm -- or idle speed in this setup. To go, you run the electric motor when turns the pump. When you stop, the pump stops. No idle speed. I see a trend towards replacing the vane pump with a geared pump (if 2 votes is a trend!). I will keep "vo...
