Detroit Diesel 6V/92 Series
Hi guys, I don't post much here, but I thought some of you would know about the Detroit 2 strokes. My Father just bought a 82 single axle dumptruck. (Ford L9000) It has this 92 Series 6V Detroit with a 9 speed transmission... I want to earn all I can about the truck as I will probably drive it more than He does.
He bought it to pull His 310 JD Backhoe. He also bought a 15ton Talbot trailer for it. Got the truck and trailer for $9,100, both in GREAT condition. Anyway I have a couple questions...
-What is a safe RPM to run at in High Gear? (55mph is screaming at 1500rpm, 60mph gets to 1800rpm) is that all I can do safely?
-These motors use oil... Is there a "fix" for this?
- Any special maintance or things I should know about common issues?
-Does anyone re-gear the rearend for Highway driving?
I don't mind going slower but I also don't know whats normal for these motors? What are they capable of? It seems like a pretty powerful truck so far... Supposedly the motor was refurbished 40k ago. Truck has 400k+ with no rust. Dumpbox was new in 2000! The truck was a tractor before converted to the Dumptruck.
