2007 Mack CV713, AMI 370 engine, unit pump came off
Mack Snow Fighter replied to Mack Snow Fighter's question in Mack Truck Q & A
Cam roller looks good, so I will put it back together with new bolts and o rings. And other quick question, On my older truck with an EM7 engine, I did a cam job recently. I didn't have the correct tool/feeler gauge to adjust the jake brake, so for now I just left the jake disconnected. Would it hurt anything to run the jake? I don't want to damage anything. Thank you for your quick response, I really appreciate it! -
2007 Mack CV713, AMI 370 engine, unit pump came off
Mack Snow Fighter posted a question in Mack Truck Q & A
Hello, Was loaded and running the truck hard when suddenly there was a loud ticking sound under the hood and fuel all over the road. Needed to pull off the road and get the truck towed. Turns out that a unit pump had come out of the block. The one bolt looks like someone would have cut the head off, the other one was broken off about flush. Both studs came out very easily. Nothing seems to be wrong with the unit pump. What is the root cause. Should I just put it back together and see what happens, or should I replace unit pump and injector? Thanks for your help!
