lowest rpm you can safly idle at Detroit s60 14L

Yes i would idle it up.

 

With a Cat, yes I'd idle it up.

Series 60, I never idle them up, and never had a problem..

 

DD S60 MOTORS
Not sure about the others, but should be about the same.
High idle rpm= better oil pressure and cylinder pressure
When you inframe your motor, for the first couple weeks or so,
you either A. don't idle or, B. idle at atleast 1000rpms. This is to keep
cylinder pressure up by keeping the rings where they belong. On a broke in motor
idleing below 900rpms will allow cylinder pressure to drop which allows the rings
to get "lazy" and wear increases.

 

i'm curious as to what torque at the rear end of tranny uipon take off has to do with the pump lubrication at an idle.

no one made any mention of emissions between an engine idling at 600 rpms and a engine running at 1000 rpms.

i know on cars. if you drop the idle down. you raise the hydrocarbons. which is unburnt fuel. the engine starts to misfire and stumble at the lower idle.
people were known to richen the air fuel mixture to smooth the idle. which lowered the hydrocarbons but raised the carbon monoxide.

in other words. lower the idle. pollute the atmosphere more. pretty easy to also not pass emissions back when the test was idle only test.

 

Normal operating psi under a load for a CAT is 60-70psi. At 700rpms normal slow idle 30-35psi. At 1,000 it ought to be 65psi. That's why you bump a CAT.

It's just the big ball bearing input shaft bearing that's spinning with no load. Used to be a day when just splash lubrication was fine for a Roadranger. Tranny will be fine at low idle.

How did you measure that? I know how, I'm just curious what tool you used. Sounds like it needs to be calibrated.

Durn lazy rings. Must be made by ____________ (fill in your ethnicity of choice).

 

Yeah, it's really difficult to use it. Really difficult to clamp it around the power wires on the alternator. Oh the strain. I should go take a 10 hour break now.

i beleive the ecm can go to 9 volts before it dies.

i worked with a driver once. called up the shop and asked for a new radio in that brand new pete. said the radio just died. and the shop told him no they weren't ordering a new radio. about an hour later he called the shop back up and said the truck died. shop asked him what the dash volt gauge read. and he said 9 volts.

can you imagine driving around town with no brake lights. idiot never looked at his dash to realize the alternator wasn't putting out.
needless to say. a new alternator also fixed his radio problem. talk about a happy camper.

 

Let's be nice.
