Sureway didn't start off with a big fleet. I'm just saying the dealer could admit they made some mistakes and keep the customer happy regardless how big they are. Steve isn't arguing over a $100.
Thanks for the response .Nothing was mentioned about the radiator until they tore into it the second time.I and the shop manager were going over just what they had done to the engine the second time, not finding the cause of the engine failure, we were brainstorming what to do next ,did he mention pulling the radiator ,checking it out and finding the tubes 50%plugged with water scale and small stones. It was an afterthought that they pulled the radiator out..
To add to that thought, the engine oil cooler was new on new long block. I am having a hard time understanding how that engine would get hot and not show hot on the gauge! The service manager said that those gauges are not very accurate ,they can be off a lot!Steve I don't remember how long you ran it but I don't think it was long enough for a serious overheat. I have a Cat 980B loader with the same engine we use for snowplowing . It pushes a 18' snow box in a large mall. It always ran hot when used hard. We probably ran it into the red on the gauge 4 or 6 times. We tried flushing the radiator, new thermostat, etc. with no help. One day it started leaking antifreeze out of the orings around the pre cup chambers. We replaced the orings and the next time out they blew again. The engine didn't over heat either time. The orings were from Cat. I tried getting help from the dealer but they had no idea what it could be. I asked for a guy with gray hair but they've all retired.
So I asked the question on here and got the answer right away. The oil cooler was plugged at least 70% with rust pieces!! That helped a bunch but after a while it started creeping up more and more. So I got a look at the top of the radiator and it was plugged with the same junk probably close to 50%.
Anyways the reason for my long post is I have the same engine ran for many hours with a 50% plugged radiator and oil cooler. It NEVER scuffed a piston or had any trouble. I can't believe a 50% plugged radiator blew you engine in such a short time. I'm glad your getting somewhere with Cat. Keep after them and good luck!
and now you are going on "spring break"??
I think that Steve is saying that his public job (perhaps in a school system) is going on spring break, and he is losing or has lost that period of days for operating his machine because it is still broken....
I don't know if they doDoes the 3306 have piston cooler nozzles?
I don't know if they do
Shop manager said that the water pump is showing wear. I don't know how they measure wear but ,I think he mentioned clearance gap between impeller and housing being too much.He said it needs a remanufactured pump .
That's a good question!!Now even more damning info is coming out. When did the shop manager know about the worn water pump, after your machine went back to them? You didn't run the machine long enough to wear out the water pump that certainly should have been checked. TAKE THEM TO THE CLEANERS!!!
