I'm currently setting up four new 3520's now. I did notice that only one engine had the stabilizer brackets connecting to the turbo chargers. My boss is contacting CAT. to order the other three sets. I noticed that without them, the entire weight of the turbo as wellas the weight of the air intake system rests on the turbo mounting bolts alone. Hope this helps.

Thank you Rick for the info on the stabilizer brackets. My 3520C engines have been in operations for 5 years I did have a bracket installed

by Cat Corp engineers to stop the turbos from rotating.

 

My engines run 14 hours per day M-F 8 to 10 June-Sept.

 

The sag is continuing each season i run.

 

Again thanks  for infor will talk with my dealer about stabilizer brackets.

 

good luck with your start up

It is my understanding that the brackets were meant for engines with a certian serial # prefix GZC or whatever it was. This is what I found 271-2347 & 271-2348.
