    JLG 45ic won't move

    These were a very unpopular b*****d type that JLG made. I would contact JLG direct if you can and get the specifics. have the model number, serial number and so forth at hand. It was basically built on the same chassis as the 40 electric, but with a dual fuel IC engine. The 45 was a 40 z boom...

    The JLG 40F Boom Lift Dilemma

    If I remember right , the 40F used the same ole Mico brake assy, spring applied, hyd released, when the threshold on the controller was engaged. I still have JLG nightmares! They mostly subsided tho when I started working on Genies. Of course they were enough old H's and TB's around to keep ya...

    Snorkel 120 lift computer???

    I've worked on several of the tb120's. The EMS system is a pain. But I will say I have never seen one of the ems boxes go bad. Every lift problem I've had has been because of a limit/safety sw. The TB 120 will not let you go above a certain height or extend the boom unless the axle is extended...

    Heavy Equipment mechanics

    No downturn in the fayetteville area of NC. I just recently left a large rental outfit and went to work for a JD dealer. More work than I can handle. Ft Bragg is wide open building stuff and its seeping down into the smaller subs. Some of the Mom and Pops are a lil slow in paying and on what...

    Any Mechanics?

    If your pressures are normal, then I would perform the cycle time tests for each circuit. If cycle times are slow, that would indicate a flow problem. Although I have limited Cat experience, on most others, if it is mistracking, it is likely a pump issue. Either the pump is worn out or it's not...

    Gradall Carnage

    Did 3 of those last year. What happens is the tapered pin gets loose in the spindle and starts to rock. Then it shears off the threaded part on top and when the cylinder gets loose it breaks off the top of the pin that slides thru the cylinder bearing. One I worked on sheared off the bracket...

    Looking for replacement Relays

    Most of the time if walk into a parts place and find someone who knows what day it is and you ask em for a 4 pin or 5 pin Bosch relay, they will hook you up. As you stated, they are all the same, just depends on if you need that 5th pin, which is a normally closed contact.

    injector pump

    By 'Turning it up" what are you looking for? Power?? RPM?? Speed?? On a hyd system, as long as the motor isn't falling on it's ass and the pressures and flows are good... guess what? You need a bigger machine! Cranking on an inj pump will cost you bucks. And if ya don't know what screw to...

    Bobcat T-300 Idlers

    Haven't seen any roller problems with the Bobcat since they went to the greased and sealed units on the 864's. On the older 864's the rollers and front idlers were oil filled. They sucked, the seals failed, what lil bit of oil was in them leaked out and away they went. Track tension maintainance...

    Arrogant Cat dealers

    Some places it's almost like the Cat dealers are a cult! LOL! But all in all in my lil area of NC, we get good service from G. Poole Cat and RW Moore for our Deere stuff. We used to have a local JCB dealer too... their gone.. too bad. Now have to go to LOw Country in Ga to get ALL those...

    580 case super m boom swings left

    Inspect the spool on that section of the valve body for a broken spring. Case hoes use an open center system. So the only way fluid can go to that function is if the spool is not in the neutral position. Or a cracked valve body, which in Cases is very unlikely. The centering spring is located at...

    questions??? Again. bear with me.

    I'm a third generation mechanic. Been doing so for pay since I was 16. Started in an old Ford dealership working on trucks and farm tractors. I've turned wrenches on everything from a weedwacker to a Boeing 737. I love my work, it pays well, but it's a pay to play world. I have more wrapped up...
