Newly starting out heavy diesel tech. Curious about if you guys enjoy Snap On’s CT 9080 or Milwaukee’s half inch more and why

I have no experience working on busses; they just seem annoying to work on. Benefits and pay is very good though. Anyone got experience with em?

Looking for some assistance regarding an EGR Cooler Temperature Issue , engine is an MX13

EGR cooler spikes in temperature the second truck starts rolling

While stationary, With wide open throttle never passes 270 degrees without cooling itself off

While stationary, During regen never passes 270 degrees without cooling itself off

When the truck is loaded and rolling, the temperature in the EGR cooler spikes rapidly and peaks at around 500 Degrees . The second you let off the throttle, the Temperature drops rapidly, when throttle is applied, it spikes again.

I have already done a significant amount of diagnostics and have not found the fault.

So far the data on the temp sensor was checked and verified, swapped with a test sensor regardless, EGR valve ECU request and actual are on par with each other, regardless Valve was replaced with a test unit, the cooler was removed , inspected and cleaned, I popped the thermostat housing and made sure both thermostats weren’t fucked up .

Would appreciate any suggestions, this is a rather odd issue . Thanks in advance

I’m just trying to get in no experience no school what route should I take?

So I’ve been in college for about a year now and I still have a hard time memorizing the firing lineup for Valve lash adjustments. Any advice?

Just curious. I normally work 8-430, then I’m on call afterwards for a week at a time. In a typical day I’ll get 3 or so service calls. They aren’t normally very long. There’s one driver who frequently makes overnight calls from for example 1am and I’ll be out of the house for a couple hours. On those nights, especially if I’ve been on other calls, I will sleep in a bit and come in at 9:30-10. Do you guys also do that?

I’m 18 and this is a new work area for me.

Just got hired for a PDI position at Rush Enterprises and I’m trying to figure out what tools I should start buying first. They told me it’s okay if I don’t have every tool during the first few weeks and that they usually give a tool list, but they didn’t have any copies available when I went in.

They also said onboarding should take about 2 weeks, so I’ve got a little time to prepare. For anyone who’s worked PDI or entry-level diesel/truck shop jobs at Rush or similar dealerships, what tools did you actually use the most starting out? Trying to avoid buying a bunch of unnecessary stuff at first

I have a 2020 Western Star 4700 with the windshield defrost not working. I replaced the two actuators on top, and the blend doors move freely by hand. Could the hvac control unit be faulty?

Anybody have large punch recommendations for removing races in Conmet hubs? I use a trailer s-cam to remove races but I'm getting too old to handle such a heavy punch. I know Mayhew makes a race punch but I was looking for something bigger than that but smaller than what I have.

My whole career has been industrial engines and large compressors.

My family is now looking to move to a new area with better weather and lifestyle for kids.

There is no oilfield work in that area so just curious what everyone would recommend switching into?

Seems to be a lot of equipment and HD truck jobs around. Haven’t worked on much equipment to be honest
