    Oil Pressure Gauge reading way low

    You are on the right track, do not rely on the factory gauges. That goes for the temp gauge also.

    Oil change for ZF-5 Transmission

    This is a old thread someone was reading and liked. I clicked on the alert and it came up. Did a lot of experimenting since 2011, it is now 2024, still have the same truck, and for past 10 years I have been running the Dexron VI in my zf. It is the best oil I have found for it, and what the...

    A "pickup" can be converted to a official dually "pickup" by simply swapping in a dually rear end from a dually "pickup". The dually pickup rearend is 4 inches wider, giving room for the dual wheels to the pickup frame. A "cab and chassis" dually rearend is different and won't fit. A cab and...

    C6 overheating mysterious cause

    C6 transmissions puking fluid out is not a common problem with those. Something is wrong somewhere. While they are fuel hogs, they are good transmissions.

    The rear tank doesn’t like to take fuel

    Not sure why that guy in the article had vacuum problems with his tank. I thought all modern fuel caps let air in, but not out. I ran into the same problem he did, not at the beginning, but later on when one of my hoses fell down. I filled the tank and some fuel got in the belly of the vent...

    C6 overheating mysterious cause

    When you get the trans warmed up, put it in park with it idling and pull the dipstick. Wipe it off and then put it in again and when it's idling, what does the fluid level look like? Is it above the "H"? If the trans is a little too full, the height of the fluid can get up into the moving...

    The rear tank doesn’t like to take fuel

    Ford knew they had a problem. On the 86-dwn trucks the fuel went down the large hose, and they had a smaller plastic hose inside the large hose clipped to the top interior of the large hose. The air was supposed to come out the smaller hose inside the large hose. The small hose was famous...

    The rear tank doesn’t like to take fuel

    This is a classic common problem with these trucks. I am surprised I haven't seen it on here like you see air intrusion and fuel pump threads. Even the gas trucks can have this problem,, but the diesels have it more because the fuel foams so bad. When you are pouring all that fuel into the...

    Before you start down the conversion road you first need to determine what you have. Do you have a pickup? Or do you have a chassis/cab truck? You can determine this my measuring the width of the frame at the rear, a chassis cab will be 34 inches wide. The pickup frame will be wider. If you...

    Sterling 10.25 oil leak

    If you are doing a complete rebuild, you could use the eliminator kit. But you will have to put it together and take it apart several times to get the pinion shimmed correctly. That is why the factory went with the crush sleeve. Tighten it down and go on the assembly line.

    Some people have been getting the kits from rockauto. I see they have one on there for $232.79. It's a 12" perfection clutch. Warning, a lot of these aftermarket clutches are oversize. So your bottom cover will not fit without rubbing. Most people just leave the cover off. I have been...

    Sterling 10.25 oil leak

    I have done this to several axles including these. Take the driveshaft loose, take the nut loose, replace the seal, and then re-install the nut. No crush sleeve needed. Getting the nut loose if it's not loose already can be a problem. The best way is with a large impact gun. If you are...

    Diesels will cause noise in the drivetrain. They hit so hard when they fire, that they shake and rattle the transmission on through to the rear, especially at idle when there is no load on the drivetrain. That was the reason for the DMF. To dampen these vibrations when the diesel engine...

    If the miss is consistent at idle, you can get the engine idling and then loosen the line on each injector one at a time. When you loosen it and it starts leaking, that cylinder should drop out. You may be able to use this to isolate which cylinder has the miss.

    Solid vs Elastomer Harmonic Balancer- Which is Better?

    A couple of the references on rockauto say "OE balancer solid". Maybe the stock balancer was solid.

    Exhaust on n/a

    As long as you do not mess with the fueling, the EGT's should stay low. I think you will like the glasspack muffler. It will tone it down some. Just make sure you do not dump it out between the road and the body of the truck. If you bring the outlet beyond the body a little bit to the side...

    Injector line nut leak

    Sometimes when replacing the return lines and bending the injection lines out of the way, the factory clamps will not fit on the factory lines, even though they did a few minutes before. Sometimes you have to force the issue and bend the lines so the clamps fit. If you are running without...

    '90 7.3idi Harmonic Balancer Fit Years

    Rockauto has 3 different ones? Only 2 are available though. It's a good place to get part numbers and do a google search to see if someone else has one also.

    Exhaust on n/a

    N/A with no muffler is way too loud. Be a little considerate of other people in your neighborhood and community. Sorry if this makes you mad, but someone has to say it.

    What years f250 idi diesels had limited slip?

    Most are worn out by now. They work a little bit but not like they did when they were new. Get the axle code off the door jamb and we can determine from that if it came from the factory with a limited slip and also find out the ratio.

    Burning up fuel shut off solenoids.

    I have seen this problem many times in my work through the years. Hydraulic solenoids will burn up. I had a safety interlock solenoid burn up on a skid steer. I have had many different relays and contactors burn up. They all get hot and burn up if they are energized and the metal core is not...
