    Alternator Not charging

    Just went through a similar set of events.. replaced Alternator, voltage regulator, checked every connection and circuit... still would not show a charge above 8 amps... After spending way to much time and money.. tried load testing the batteries [which were both new and therefore "couldn't...

    Buy it or leave it?

    10 lug wheels tell me it's an F 450 .. not a F 450... I have a 450.. 2WD Dual, cab chassis.. would be kick ass to make it 4x4 .. but it's a beast as it is.. The D60? is it king pin.. ?

    Weird steering and hub issues???

    Did you inspect the wheel bearings themselves? Remember you have a third bearing that carries the axle into the hub.. that bearing has it's own seal also.. I've found several on tear down that have never been serviced. If you have a wheel bearing that is galled, it can run OK for a bit...

    T19 Manual tranny/ throwout bearing squeak

    How did they grease the throw out bearing? There is NO grease zerk on it.. Sounds like they used the "Throw enough shit on the wall until some of it sticks" method.. and sent you down the road.. Go to a parts store and ask for a throw out bearing for your truck.. take it out of the box and...

    ZF5 question

    On this same thread.. anyone have a trick for getting the fill plug out? Mine is super stuck, locked in.. steel plug in aluminum case, so if I get violent with it. it will rip the threads out of the case.. [no, no no no]... With the fill plug stuck, I really can't check the oil level...

    2" semi-trash pump for waste oil transfer?

    I've been using the same setup only the little 1 inch pump.. Works find.. pumps a bunch of oil, or diesel, either one. The only trick is to make sure the pump is primed full of what ever you are pumping and there are no vacuum leaks. I use ball valves on both inlet and outlet of the pump...

    Possible steal if as advertised?

    Missing title.. buy it only after you run the VIN through your local cop shop to be sure it's not hot. NOTORIZED bill of sale, with a release that lets you sign in his behalf for the state to issue a duplicate title.. and then execute it. It that passes, then fix the tranny,, and drive it...

    Pick up a rebuilt set of 7.3L heads that sat for a while, what should i do with them?

    Looks like they were stored without being oiled and wrapped in plastic which held moisture from somewhere.. Should clean up.. good idea to send them through a machine shop that knows what they are doing with diesel heads and clean them up, check them over. Last machine shop may have...

    No start hot turned to intermittent hard start

    Question: Do you have the engine driven fuel pump? If you do.. how old is it? Sounds like you are having a no start because you don't have fuel. I had this problem.. drove me nuts.. finally discovered the engine driven fuel pump had a pinhole leak in the pump diaphragm.. On shut down.. it...

    Tach Sensor

    My 92 was acting the same way.. Pulled the sender on the IP housing case, cleaned the face of the magnet and it worked for a while longer, still wasn't satisfied it was giving a good signal to the tac because the readings seemd low.. Replaced it with a new one.. fixed the problem instantly...

    guide coats for the rookie

    A light spray of a contrasting color... [OK.. not hot pink]... but if your primer is medium or dark gray.. a white spray bomb will work.. Hold it back about 18 to 24 inches and put down enough to only make dots of color about 1/2 inch apart... it should be "dry fast" paint.. no oil based enamel...

    starter

    Even though you have a bunch of batteries , have you load tested each one individually? If you have one battery with one bad cell [or more] it may read as having 12.5 volts, until you load test it.. Step by step: 1. Load test each battery in the battery bank. If you have one battery that...

    Any way to test vacuum pump?

    First thing you should do is ADJUST YOUR REAR BRAKES. The automatic drum brake adjusters on these trucks seldom work properly, and as the shoes wear, the peddle lowers because it takes more fluid to expand the wheel cylinder further. Simple test is push the parking brake on till it "almost...

    coolent passages on head gaskets?

    Diesel engine is a compression ignition engine. By keeping the head "hot" it enhances combustion thus ignition. It also likely is why the heads are so often cracked .. the cast iron head does a delicate balance between retaining enough heat to augment combustion to "light off the vaporized...

    Picture did not post. Likely because you didn't use the "Go Advanced" posting feature ... Please try it again..

    91 7.3 siezed after sitting for 2 hours?

    From a recent experience with a chevy engine.. you describe all the symptoms of a hydrolocked engine.. In my case,,, had a fuel injector blow off the tip and fill the cylinder with raw fuel.. while testing the fuel pump.. not running the engine.. went to crank... engine cranked 3 revolutions...

    another glow plug controller thread

    Scrape some of that fancy damn powder coating off where the glow controller bolts down so the black wire actually makes ground.. betcha it will work.. Just a thought.. Over the years, I've had more electrical issues due to bad grounds than I can count.. [with my shoes on anyway.. ;)]

    THE GREEN BEAN!

    Do a google search for "Dustless Blasting" while you are planning your body restore, or for that matter, the frame also.. Does a truly wonderful job on tired paint and sheet metal without distortion of the metal and leaves a near perfect surface to take paint.. Or.. go here and click on...

    Painting a rear bumper

    I would buy a couple cans of spray paint stripper... take all the rubber step pads off , set in on a pair of saw horses [or trash can] away from anything I didn't want stripped and spray it with a coat of paint stripper. Wait about 20 minutes while the stripper works... then wash off the paint...

    Greaseable or sealed ball joints?

    Grease them. Nothing ever wore out from over lubrication. "Live time greased sealed units" are "life limited to how ever much grease you don't lose over time". Spend a couple bucks for a Harbor Fright air operated grease gun. You will then plug in, pull the trigger, and move to next zerk...

    How low to run tank with broke shower head

    Excellent argument for installing an electric fuel pump.. Re-prime the fuel system by flipping key on/pump on.. bleed air out at schrader valve at the filter... crank engine.. Grief factor is much shorter than cranking the engine to run mechanical pump till you get fuel pumped to IP after...

    Powerband and fuel consumption figures?

    Your generator needs to spin at 1,800 RPM exactly to make 60 cycle, 120 or 240 power, or 3 phase, either one. Most generators are direct drive right off the crank.. some are belt or gear drive for slow speed engines, but the generator still has to spin at 1,800 RPM ... of 3,600 RPM, depending...

    remote mounted batteries..whos got em'?

    I have two 8D batteries in my 40 ft diesel pusher [24 volt system].. I can tell you they are a bitch to handle by yourself to maneuver into the battery box position for the pair. It is a two man job. Previous 3 40 ft diesel pushers used 4 Group 31 batteries and they were much more manageable...
