Something seems to have changed a bit. The "Select File" icon wouldn't appear for me, in the lower right corner of the Image Manager box there's an icon "Browse Computer". Click that and you can access your files. Not sure what happened but that will get you through it.

It's been quite some time since my last appearance here in HTF. I figured I'd "wake it up" a bit with some updates and recents, lol...

Still running the restored A Model daily, after a LOT of upgrades since the last posts...It'll be 2 years this February that I bought it, ripped it apart, and reassembled it...and been working on it constantly ever since.

The mill calved on me back on May 29th on I-81 in Pennsylvania at the 107 mm northbound, with a load on of course. That was the original 3406A PCTA 375 horse that was never really on my favorites list to begin with. Never had a whole lotta power even after some good old Cat guru mods. Not much you can do with those archaic PC fuel systems.

Got it home, peeled the old motor out and replaced it with a newer (1982) 3406B I had hanging around. Before dropping it in, I put a Jake on it, rods & mains, front and rear seals...painted it and dropped it in with a new clutch too. Had the radiator recored and all new mounts..whatever it needed I did. Down for 32 days, 2 weeks was the radiator job.

Now I'm happy with this motor. It was set up by the same Cat guru that did the PC motor, actually took the turbo he built from the PC and put it on the B, new AFR valve, a little fuel...she runs like a 7FB 400 should now. I've touched 7 mpg in perfect conditions with it, averages about 5.5 mpg. The A at best was a 4.5 mpg hog. Just the fuel savings alone equates to a serious amount of money saved as opposed to running that old engine. The old engine drank around 4 gallons of oil a week, and about 2 gallons of anti freeze too...so that adds up to even more savings.

Added some nice vinyl graphics to break up the solid color until I get rich and get it all repainted. I designed this one-off version of a factory KW scheme myself by thinning out the design on the hood a bit.

While having all this fun, I removed and sold the rollback bed off my other 78 A Model, and stretched it to 282" WB, making it a tractor because I have more use for it than I did that rollback. The rollback was cool, but I made more friends with it than I did money unfortunately. Everybody knows you have one, and all figure you'll move their skidder or 1 ton around for a ham sandwich. Meanwhile that rig costs just as much to insure and run as a tractor does, so I decided to convert it to a more functional rig. Still gotta finish it...need to add a couple cross members, a driveline, 5th wheel, plumb air and juice to the back end. In time...spare time project is what it is now.

Since the inception/debut of this truck in April of 2017, I've added an aftermarket Vintage Air a/c~heater unit for comfort, hydraulic power steering (the air assist went bad and I was ecstatic when it did,) and countless other little mods along the way.

I cannot get any pics of the other '78/former rollback truck to post here...won't allow them for some reason. Oh well.

Yeah Jason that visor fits the A Model cab just right, The W900 A with the rounded cab, fenders and hood just make a cool looking machine.

I'd love to add some more recent pics, but I ain't having a bit of luck adding any files at all anymore. Keeps telling me Upload Failed. I've tried numerous times. I never changed anything since the last group of pics, but I can't post any now for some reason.

Yeah, something's changed here. I'm trying to add another file for an experiment but I keep getting a failed to upload message. Different sizes, different pics, can't get them to load anymore.

Check the file size, I don't know offhand what the limit is but it should say when you try to load. If the file is too big you'd get the failure notice. Let me know
