7.3 thread continued?

I've not had any issues with it starting from cold, especially not not at warm temps like 9*.

Not many gas engine C&C OBS around here. This one was from BP. Until ULSD came about most of their fleet was diesel as they refined their own fuel from oil just a bit down the pipe.
They had hundreds of 7.3s and 6.0s.

Now most of the light duty is gas converted to propane which they make for near free.
That’s Hilcorp now right? Hilcorp bought 100% of BP and 51% of the Alaskan pipeline.

Yes, bought out around 5 years ago. They bought ENI last year too. They were "offshore" on 2 man made islands... aka dump gravel till there's enough land.

Nikatchuq and Ooooguruk... or something near that.

Quick fuel line question since I can't get to the truck to take measurements.

Not exactly sure how but the braided into steel fuel line out of the fuel pump on my 2000 F-550 sprung a leak. Since I haven't been able to find that line for sale and RiffRaffs conversion kit is out of stock has anyone just ran flex line? If so, is the adapter fitting on the fuel filter bowl 1/4 or 3/8" NPT where it goes into the bowl?
 
ZF6 started making noise on the way home last weekend. Tried ignoring it and that didn't help. Had time to change the oil tonight and its got glitter. I don't have the time or the resources to rebuild it, so I have to pay that problem to go away. Hoping the guy who's number I got will do cash work out of his house like he did ok buddy's nv....whatever a dodge has.

I've read that zf's are a bitch to rebuild and parts are pricey.

Gonna drop it and take it to a local rebuilder on monday.
Quoted about $3000. I could buy an unknown condition 280,000km one that's $500 in ferries away, or have mine gone through. Or spend $50,000 on a new used 6.7 truck. So instead of that new hunting rifle I've been saving for for the last year, I'm gonna buy a transmission rebuild:bawling:
 
01 f350 7.3 zf6, manual shift case. 589,xxx kms on it.
I tow almost every weekend. Not too heavy, probably 6000ish lbs, plus a load of bikes on the back. Truck scales just under 9000lbs typically. Big bumper, winch, heavy deck, a lot of tools, etc.

A month or so ago it started growling badly while towing home. I checked all U joints, which felt happy, spun the front wheels...all I found was some ****ed ball joints. Did a tire rotation. No changes.
Trans juice was pretty sparkly. I dropped it, had it rebuilt. Rebuilder has an excellent reputation. It no longer growls. He did bearings, syncros, two hub and sliders, input shaft and one fork.
I did a sintered bronze pilot bushing instead of a stock one.
However.
There is still an oscillating type noise from about 55-65 km/hr unloaded at neutral throttle. Zero pedal, no noise. Hard on it, no noise.
Towing, it's there from 50ish km/hr up to around 90km.
It seems to both my wife and I (from her spot in the passenger's seat), to be coming from right by my feet while driving.
I've done the rear end fluid, it was happy. I'm waiting for another u joint and I'll do the center one on the rear axle this week. That will be the last one.
Tcase fluid looked fine.
Manual case, manual hubs, so nothing in the front end is engaged or under load. I marked the front shaft to make sure it wasn't spinning, went for a drive, confirmed. Noise is the same in 4H with hubs unlocked, as in 2wd.
Any ideas?
 
Does it have a double cardan for the rear drive shaft? My little sisters Excursion was doing that. Couldn’t find it until it got way worse. The spring loaded center pivot was shot. Bro in law had our driveline shop put a whole new one on and it’s smooth as silk again

No juat standard u joints. And they all feel great, nice and smooth.
 
How did your ZF6’s output and transfer case’s input shaft look? I did a t-case in an OBS F350 (ZF5, BW t-case) and they looked bad, rusty, and wearing down from rust grits.

How hard will it be to drop the transfer case to give it a closer look when you do the u-joint? NV271F?

My NV271D looked and felt “fine” in-vehicle. Dropped for NV4500’s overhaul so I had it sitting on the bench. I took another look and it had potential issues. Split up the case halves, and I was glad I did. Its sprockets were toast, loose chain, and ball bearing on front output felt fine assembled but clearly junk after disassembled, rolls rough in hand, ball and race all dented up.
 
Looked rusty but not bad. Output on trans was declared good by rebuilder.

Definitely could be the t case.

Yes, 271 of some flavour. Its a bitch to drop, but could be worse.

I'll shop around for a spare, and maybe do a rebuild on that, then swap it in.
