With a trailer on ‘as a Test Drive’ the 46k right bag under mine I noticed nearly no sway. Had a load of live trees my ex boss ‘allowed’ me to move from tree farm to yard, all rolling two lane

90 ton cleaning grounds didn't fix transmission. We've got it so it will act up reliably in test driving today, now to find someone that can fix it....

Most likely a Solenoid group or a TCM fault, could very well be a glitch in the harness.

Transmission expert from Pennsylvania says likely not transmission but ABS system.

Keep informed, has my interest how that works.

Ah, I believe it works through the miracles of can bus. Which is the equivalent of magic to me. I'm not sure how you send different information both directions through wires,
I'm of the school of : #1 I have voltage, or #2 I don't have voltage, and I can troubleshoot from there. But we'll get it sorted eventually.

Most cars, Harleys after 2013 have canbus, multiple signals same wire differing frequencies or some form of voodoo so they go to their respective points not affecting others.

What happens if you disconnect all the antilock sensors?
crane operator

I don't know.
Late yesterday they found one of the ABS wheel sensors badly corroded and possibly not working correctly.
Cleaned sensor and connection up, triple checked all the other connections, and bumped up the air pressure in the governor (air pressure has always been a little low- and book says pressure is critical for transmission shifts). The test drive today, everything worked correctly, no error codes, no issues.
Current theory: ABS sensor bad, ABS pulls away throttle, throttle gets jumpy when pulled away, so that threw the error code on the transmission. When we thought the transmission wasn't shifting, it actually was shifting, and the ABS module pulls the lower throttle away, so that the operator thinks the transmission isn't working correctly. Maybe.

Be prepared to change out all ABS cables and sensors, cleaning the connections only works for
short term, once those corrode tough to clean. Be glad it doesn't have ABS traction control, or
does it.

Not sure, to be honest about it. I know its ABS but don't know if its also traction control.
That's not great news about changing all the cables. They said all the other connections were great on the abs, just the one looked bad.

Got prices for adding timbren rubbers to the AG100 today, $1,200 per axle.
Concerned the timbrens may affect off road travel articulation of suspension.

It will to some degree.
Use a Q-tip and brush some dielectric grease in all ABS connections and around the connection
sealing surface to keep water out.

linkbelt 8660 with the rear steer axle option. Coming up for auction. Think maybe the steering linkages are bent that connect the drive axles? I'm going to say it drives down the road a little wonky and scrubs tires pretty fierce.

i'd want to see the other side.

Its just as bad. I ran a grove that had the rear steer axles for a while, and it was nothing but trouble. I know of another one that the rear steer was all disconnected.
I went through the pictures of this crane on the auction site, and they have all the hyd. lines to it disconnected, and its obviously all jacked up. Most times, they just get the axles both pointed straight ahead and lock them in place, but they evidently just sent this crane to ritchie bros instead.

Chevy built a pickup like that about 15 years ago-that design kind of flopped, didn't last long.

They are pretty rare in the truck cranes. Most guys mess them up from not reading the book. They will only handle around 46,000lbs, but you get way over that weight, if you have all the counterweights hanging on the upper rear with the boom in the rest. The book wants you to leave some on the deck and take some off.
Invariably someone leaves the counterweight all hang and then tries to go through a mudhole and steer the rears. Then the steering linkages get bent or broken.

Mazda made an MX-6 with 4 wheel steering in the 80's. Honda did that too and neither company carried that idea forward.

Put the press to work this morning, pushed in some new torque bushings in the grove 40 ton.
The frame rail side wasn't real bad, the one on the axle housing was gone. Put new in both.
