    Gerotor lube pumps - subject matter expert

    Cody I designed the new homopolar generator they are looking to use for that down-hole system that replaces batteries. For BNI. Has a tungsten flywheel to keep it rolling when a low pressure pulse happens and runs on the high pressure mud. Weird stuff. Had to fill it with oil and seal it so...

    beryllium copper is good stuff. They use it in some high-fatigue, high displacement spring applications (feedback springs for servovalves) since the 50s. The aerospace industry is so adverse to change that they only use it where it is necessary. New materials are slow to be used.

    Right now, the properties are all over the map. MatWeb - The Online Materials Information Resource Unfortunately, you need to design for the worst case properties, which means not only using the minimum reasonable yield, but a de-rated value below that based on the highest temperature you...

    Gerotor lube pumps - subject matter expert

    Cody If anyone has the measurements I can make a print. If it is just an adapter plate with that pilot bore, it could be hogged out of plate aluminum. Might not actually be prohibitively expensive. It looks like an adapter coupling would be needed for the drive if you are looking at any...

    Gerotor lube pumps - subject matter expert

    Cody Cant share pics of the guts. Gerotors are only made by a select few companies, and they control everyone that works on them with a non-disclosure agreement. I can only share stuff that is already 'in the public domain'. About half the stuff in the air has a gerotor pump, in which case I...

    No Radio Power?

    Just swapped out the head unit in my 2000 LC with head unit and amp bypass harness from Crutchfield. Same problem - everything is dead. The fuse in the kick panel is live. The fuse under the hood is live. The wires at the dash are not. Did anyone resolve this? I am measuring at the crimp...

    Mystery Fluid - water? from transmission bell housing

    Very cool. I am up 285 in Conifer. I plan to use the CTS (Colorado Toyota Specialists) there. Hear anything good/bad about them? Headed camping to Moab in a couple weeks. Hoping KLEMAQ the VI is in shape to play. I previously had my stock 2003 Sequoia (KLEMAQ the V) thru Fins N' Things and...

    Hey 2000LC owner and beater here. A general note. I am an aerospace engineer who designs lube pumps, cooling pumps and hydraulic flight controls. I LOOVE this forum and plan to spend a bit of time here. I have my own engineering consulting company (Nickerson LLC) and am interested in acting...

    Mystery Fluid - water? from transmission bell housing

    Holy Carp! I wish the rest of my life had a forum like this. Knowledgeable, fast answers with diagrams and experience??? I didn't think about areas the fluid could pool on top of the engine. I engineer gerotor lube and scavenge pumps for gas turbine engines (for flight). We always have a...

    Mystery Fluid - water? from transmission bell housing

    Newbie here, but I did search. I promise. I just got my 2000 LC home. 220k miles. Not the best condition, but I don’t intend to treat it delicately so that’s fine. Jacked up the front end to work on the steering rack bushings (VSC deploys on highway - very scary) when water starts dripping...
