It’s a busy Monday morning in the shop! Clutch brakes, wheel seals, springs and shocks, and motor swinging!

Down at our shop we’ve learned that when good things fall in our laps we need to run with it, so we’re happy to announce that Slim now has help in the shop! Help us to welcome C**t to Slim’s Diesel Repair! He’s worked many years in the mechanic industry on different equipment, and Slim is excited to help him expand his knowledge.

So we will be opening up our books and able to take more appointments and get your trucks in and out quicker.

It’s coming! We plan on running the grill for fresh local beef burgers too!

Happy Monday!

We want to congratulate the Worland High Skills USA welding team for their 11th place results at nationals! Out of 44 competing teams, that is OUTSTANDING! These boys are so fortunate to have an awesome instructor helping them to achieve their goals!

We love supporting our community and youth, so we were pumped to see our bench was place out at the fairgrounds as well.

It’s looking to be a busy week in the shop!

And don’t forget, our customer appreciation bbq is June 26th!

Today’s question… who was the last guy in here?

Head gasket job on a Duramax, thankfully for our customer the heads look great and we can save him some cash there, but whoever installed the injectors did the truck owner dirty. Half of the compression washers were either missing or installed incorrectly, and all the o rings torn on the other half. Plus 99% of the hardware was stripped out completely adding tons of added work on Slim’s end. Thankfully we have all the replacement parts we need on the way, and we can start the cleaning process for going back together.

Truck #2 is in for replacement brakes on the rear end… which for a Powerstroke dually means wheel seals and more, so we went to double check the differential oil and it was LOW. Who was the last a hole in here? (It was us by the way 😂) This customer’s last oil change and inspection we advised him that his rear brakes were nearing the end of their lives, and his rear pinion was leaking but levels looked good for now. So luckily the brake failure saved him a rear end it looks like! 👏🏻

We are still running a little behind schedule but we’re diligently working to get every truck back to the highest standard and on the road.

We will forever recommend our fuel systems run through Industrial Injection! This 12 Valve drove off the lot this morning running like a top and ready to hit the highway.

Our customer came in for an oil leak concern, and Slim noticed that the leak was coming from the injection pump. We pulled the pump and sent it off for a rebuild. The guys at Industrial were able to help us set this customer up for success as he builds horsepower in the future.

We finished the install on a 12mm Dragon Fly, set to the already installed 50 horse injectors, so down the road there will be no need for pump changes, we will be able to tune and set this Dragon Fly far past the 650 horse that our customer eventually wants to hit.

Being able to install your P7100, and have an immaculate start up with no need to set timing is really the cherry on top.

We’re rocking through those big projects as we’re closed. Can’t wait to get the next truck rolling out!
