    Sullair under speed problem

    I've seen that same thing on a Sullair 375, it was the alternator. The tach/speed signal comes from the alternator on most mechanical diesels. The engine is a Cat (not a Perkins, a real Cat)

    Ford LSG423

    The LRG423 was a 2300cc engine based on the engine commonly in various Ford cars thru the 70's and 80's. See the list of vehicles in the posts above. Everything built 1975 and later was electronic ignition. (no points) The distributor from any one of those engines should work for you. Jobber...

    Genie Z45/25 boom lubrication

    I remember when we saw our first Genie. We all stood around and laughed at the non-greaseable "plastic" bushings on all the pins. We were all pretty experienced at replacing pins and bronze bushings on the old JLG's, and we could not imagine how plastic was going to last longer than a month...

    Genie Z45/25 boom lubrication

    Grease attracts/holds dirt and sand, which make things worse over time. I believe they were made to be left dry.

    HYSTER H 3.50XL

    probably an electric shift transmission. Try and locate the shift solenoids (coils) on the transmission. swap coils and see if your problem changes direction.

    The JLG 40F Boom Lift Dilemma

    Here's the part numbers to go with the diagram you posted. I don't see a spring in yours - ref. #20 I don't see a ball - ref. #26 If that picture of the valve I posted is the same as the one you're working on, I have a new one.

    The JLG 40F Boom Lift Dilemma

    The picture you put up is what I would call a Racine Dump Valve.

    JLG 40ha drive motor engaging with foot switch

    Sounds like a controller problem alright. the controller is a plug-in, right? not individual wires? Strange still that the brakes aren't coming off. Try taking a wire off the high drive toggle switch, and see if that stops the problem.

    slow fork drop

    Is it cold there yet? I was thinking lighter/better hydraulic oil. When it gets too thick, forks don't come down anymore.

    The JLG 40F Boom Lift Dilemma

    Do know what I mean when I say the lift cylinder's lower pin is secured by something that looks like a main bearing cap on an engine block? It is. The nuts are under the chassis, 4 of them. have you undone those nuts? pounded the bolts up with a dead-blow hammer to loosen the caps?

    The JLG 40F Boom Lift Dilemma

    Mitsubishi 5k worehouse forklift

    I see you're from Alaska? Arctic 15 is ok, but when things are still too slow, we will use 0W30 or 0W20 synthetic motor oil in the hydraulics. We used Amsoil Synthetic ATF years ago but it's real pricey. Back them it was the only game in town. We also used to cut 22 hyd oil with 50%...

    JLG 40 G Problem with no left swing.

    These JLG numbers are coming from a fax I saved that I received in 1988 from McConnellsberg PA I believe hanging onto stuff that long is a mental defect btw.

    JLG 40 G Problem with no left swing.

    Yes. I looked up on an exploded view, and the part I remember falling out on me was a poppet. JLG part #7000423 and I think it might be too light to made of anything magnetic.
