    Transmission ZF-5 Done

    Sounds like something in the shift mechanism. Decent chance it's not in the actual trans case, if something was messed up there I'd expected the trans to be locked up completely. I would pull the floor pan and take the shift mechanism cover off to see if you could fix it there without...

    Trailer decisions

    Should be okay. Probably your weakest link is the brake system. Official Ford spec GCWR for a 6.9 auto w/ 4.10 is 14,000lb (1985) which gives a max trailer weight of 7-8k depending on your truck light weight. That being said, the 460 auto w/ 4.10 rating is 18,500lb, or ~10k trailer and...

    Dt466 turbo ????

    Expensive part isn't really the turbo, it's all the other stuff. You can fab a system if you have the time and skills, but it's not the easiest thing in the world.

    Off Brand Turbos?

    There's a reason they're cheap.... is the couple hundred bucks in savings worth the risk? Certainly not to me. Manufacturing a reliable turbo is very demanding from a metallurgy and precision machining standpoint - Good quality control is important, and it's going to be very easy to make...

    Tech 101 Custom battery cables

    Might want to look for adhesive lined heat shirk - it's thicker and the adhesive seals everything up. Also, del city is a good vendor for electrical connectors, cables and the like if anyone else is looking to do this. Also a good source for trailer lights and connectors.

    Dt466 turbo ????

    My IH book says the early DT466 truck engines used a T04B or E non wastegate turbo speced for ~18 psi at 2600 rpm / ~14 psi @ 2000 rpm and with a 1.15-1.52 AR. I would think it would be too much turbo for an idi which would give slow spooling and maybe low boost - might work but I doubt it...

    can this be done instead of rdt?

    Disagree. It's main purpose is to prevent a plugged air filter from pulling a suction on the crankcase and running the engine on oil fumes. There's no oil drain out of it and nothing inside consistent with anything other than a big flapper valve. You do get a certain amount of oil condensation...

    Serpentine Belt Trucks in Rancho Cordova Pick-N-Pull

    Yah, I put blocks under the rear end when I unloaded it.... just didn't think of it. :rolleyes: Load was actually within rated capacities of everything. Not by much, but still ok, and I drive very carefully with that much weight. That trailer is a 1970's Zieman that's rated for 14k IIRC with...

    Serpentine Belt Trucks in Rancho Cordova Pick-N-Pull

    IDIot, IIRC one was and one maybe an x-cab? One was around the east end of row 52 or 53 and one the north end of 58 (?) Didn't pay too much attention honestly, I was a bit burned out after loading a 5 ton tractor with a come-a-long.... :rolleyes: (tractor ran but clutches slip so it wouldn't...

    Serpentine Belt Trucks in Rancho Cordova Pick-N-Pull

    Terrorizing squirrels at the moment... LOL It's just an around the ranch rig - it's a nice compliment to the backhoe with the ripper & 4 in 1 bucket, and will be less likely to get stuck / will help pull the backhoe out when I get it stuck.... 2wd backhoe with bald tires makes driving on a...

    Serpentine Belt Trucks in Rancho Cordova Pick-N-Pull

    If anyone is looking for a serpentine belt setup there were 2 idi trucks in the Rancho Cordova (Sacramento area) pick-n-pull that looked to have all the parts as of last Saturday. One also has what looked like a BW4407 t-case on a E4OD trans - never seen one on an idi before. Big heavy looking...

    6.9 head stud upgrade possibility?

    I doubt you'd break into the water jacket, the main issue would be the small increase not being enough to clean up the thread and also the possibility of misalignment if doing it by hand. Only safe was I can think of to do it would be to oversize the hole significantly and then insert a threaded...

    aftermarket fuel level gauge

    Any gauge co should have them. I recommend Isspro for gauges and senders, but pretty much any should work. Just make sure the ohm range matches the gauge you use - shouldn't be an issue but always good to check. Is just replaces the actual resistor unit on the in tank part - little square...

    aftermarket fuel level gauge

    Not really possible, at least not without serious work. Stock gauges appear to be about 10-75 ohm (f to e) whereas the standard aftermarket is 33-240 (e - f) IIRC - both the values and the direction is off, so you'd get something that moves the wrong way and/or is inaccurate. Might be able to...

    fan clutch problems

    What IW posted above is the classic symptoms of a low on oil clutch - it doesn't have enough fluid to stay locked up, and shortly will be bad enough to stop working entirely. Just throw some more oil in and I bet it'll go another several years at least.

    fan clutch problems

    You woln't hear it unless you're going fairly slow - probably 30 or lower. It may also come on gradually so you don't really notice it. May not even have come on at all if you're able to do 55 - generally you've got enough airflow at highway speed to not really need the fan to fully engage. If...

    Solution for worn ring gear

    Been having problems recently with a worn spot on the ring gear and the starter grinding but I've managed to get a workable solution using a second starter solenoid as a relay. The standard starter setup uses the solenoid to pull the starter pinion partially into engagement with the ring gear...

    fan clutch problems

    Negative, all 7.3 PSD trucks spin the wrong way. Horton has a selection of fans in their catalog and I found some that looked like they would fit the idi clutch but don't know how much if any flow improvement you'd get. Before you go spend $$$ on a new clutch try refilling the oil in the...

    Eye candy!! 7.3 Marine 275hp

    That power rating isn't that far off from what a standard idi with an aftermarket turbo will get if you count the differences between net and gross HP as mentioned above, so I doubt there's much special about those engines internally. Marine practice generally lets you have higher power ratings...

    Eye candy!! 7.3 Marine 275hp

    The box on the top is a water to air intercooler. Don't see a blow off valve, just the hose to dump cooling water into the exhaust.

    Ran hot one time

    I would do the oil fix first before messing with a new clutch - same labor and much much cheaper. http://www.oilburners.net/forums/showthread.php?64852-The-4-fan-clutch-fix&highlight= First test I would do is to cold start the engine and then immediately (within 5-10 sec, not like...

    Ran hot one time

    Ah, forgot that's how they do it on the later rigs. 80-86 has a 'engine temp' light. Yes, that is for temp and oil pressure. When I see 'check engine' I automatically think of a gasser OBD setup. cookoo Fan clutch is hard to definitively troubleshoot. From the sound of it I'd bet that's the...

    zf5 swap from t19

    Also the 13-45 shift boot doesn't fit quite right - reason is that the pivot to floor pan distance is larger with the ZF pan, so the lever moves back and forth further that the pan level and the boot doesn't bend right. Minor issue though. I've had good luck with the regular needle type...
