    Roadside assistance

    We use http://www.usrider.org/ They cater to the crowd that hauls horses. They've been good to work with the one time I needed help.

    Steer tire life (sidewall cracking)

    Our steer tires are dated 12/2013 and so they're almost 7 years old. One tire is starting to show cracking alng the center of the sidewall. What's the thinking on lifespan for steers in our application? Should I look to replace them at the start of 2019? The truck will sit all winter.

    Anyone have the Yokohama RY023 in 215/75R17.5 ?

    Thanks...that seems to be the case.
  4. Does anyone have this tire on their trailer? I've seen some conflicting information on the speed rating for the tire. The websites say it's a L (75mph) but I've seen mention that some people have gotten the tire and found it to be a J on the sidewall (62 MPH). Thanks! -jeff

    It's been that way since mid last year. Maybe 15k? I have the steers at 90 to start. That's based on our front axle weight w/o the trailer on. We could go less pressure there with the trailer on, but that wouldn't work well otherwise.

    Pressure makes a huge difference. We are not singled, and went from over 100PSI to 70 on the drives and the ride is so much better.

    Removing VED12 EPG shutter

    Without the EPG the truck could be slower to warm up, and may struggle to stay at temperature for extended idles in cold weather.

    Tires Hot?

    I have a TPMS with temperature, and the inside tires are always a bit warmer.

    Splitter woes

    It was still failing after the TCU was replaced. They had cleaned the range valve and replaced the O-rings in it, but not replaced it. I insisted and it solved the problem.

    Splitter woes

    Interesting data points. The actual problem on our truck was the Range Valve. Swapped that and it was solid for the drive on Saturday.

    Splitter woes

    The mechanic called today and said it was the transmission control unit. 😞 $1300 for parts.

    Splitter woes

    We have a 2007 780 (D12) with a 10-speed Eaton Fuller Ultrashift rto-16910b-dm3 On the way to the race track today, the splitter would sometimes not work, and the transmission wouldn't be able to switch ranges. The gear display would alternate between showing F and a gear. For a while it was stuck in low rage, when meant 20MPH top speed. I pulled to the breakdown lane and checked the diag display which showed: Splitter High actuator (VAHS) Electrical fault inactive (7 events) MID 130 SID 35 FMI 5 Splitter High actuator (VAHS) Mechanical fault active MID 130 SID 35 FMI 7 I also retrieved the fault codes from the transmission (2 or 4 key turns) and got 41 and 43 I drove for a bit in the breakdown lane at 20MPH and eventually it shifted from 5th to 7th and I was able to limp it to the track. The track folks called a local shop they use and they're going to come look tomorrow. I've got a video of the problem at: https://www.dropbox.com/s/69s0l1ujmz25cvj/ultrashift fail.MOV?dl=0 Any ideas what it could be?

    Volvo running warm

    Have you replaced the radiator cap? Have you had the system pressure tested?

    Engine Brake Volvo D12

    If you start the truck with low air in the tanks, you should also hear the exhaust brake come on as air pressure builds after you start the engine. The Volvos use the exhaust brake to help the engine warm up faster (and stay warm at idle).

    Tire Pressures

    We have 17.5"s as well. Starting at 125 we'll see over 150psi on long trips on hot days.
