Is there a problem with the cat 3126 engine?
We have Cat 3126 engines. This is the second time this has happened after a day out! We call an engineer who had a look round, restarted the engine and could not see any obvious visual issues. He said it could be a duff sensor but it would be difficult diagnose and expensive too.
What kind of engine does a cat 3116 have?
I used to own a 3116 powered boat. Not exactly the same engine, but yours were derived from the 3116, sort of. I did experience an unwanted engine shut down, only once during 17 years of ownership overall.
Where is the manual stop button on a cat 3126?
The red button on the right side of the cylinder is the manual stop, btw. Here’s how it looks like on the 3116. I guess it’s neither much different nor far from that placement also in the 3126, but I can’t be positive about that.
How do you troubleshoot a cat engine in a truck?
Start your troubleshooting by grabbing the CAT engine book that came with it. Then use the cruise control switches in the truck to read the codes using the check engine light.
What kind of fuel injection does a Caterpillar 3126 use?
CAT used a new fuel injection system called HEUI to allow computer control of the injectors. A HEUI injection system (also found on Ford Power Strokes, as well as other engines) uses a second oil pump to boost oil pressures to 1500+ PSI (I don’t know the maximum) and essentially use the high pressure oil as hydraulic fluid.
What happens when you hit the brakes on a 2001 cat 3126B?
My 2001 3126B shuts down when I hit the brakes hard. It has done this at 35 MPH and at a coast in the shop. Feels like an electrical/electronic shutdown as it is instantaneous. Does not loose power it just shuts down. Starts right back up and runs fine but don’t give it a hard brake because it will shutdown.
Where is the fuel pressure gauge on a cat 3126?
It should read 60 psi after briefly cranking the engine.If you get 60 PSI QUIT CRANKING. – the fuel pressure regulator is on the rear of the head. If the fuel pump is working, test by putting a gauge into the port on the fuel filter base.
How to check the active code on a caterpillar truck?
All ACTIVE codes may be viewed using a Caterpillar electronic service tool or by performing the following procedure. Turn the Cruise Control ON/OFF switch OFF. 2. Move the SET/RESUME switch to either position. Hold that position until the YELLOW lamp begins to flash.
What are the fault codes for a caterpillar?
Caterpillar Fault Codes PID/SID FMI Fault Description 1 11 injector solenoid cyl#1 current below normal or open 2 11 injector solenoid cyl#2 current below normal or open 3 11 injector solenoid cyl#3 current below normal or open 4 11 injector solenoid cyl#4 current below normal or open
How does the HEUI work on a Caterpillar 3126 engine?
A HEUI injection system (also found on Ford Power Strokes, as well as other engines) uses a second oil pump to boost oil pressures to 1500+ PSI (I don’t know the maximum) and essentially use the high pressure oil as hydraulic fluid. And the computer would control the high pressure oil which then controlled the injectors.
What to do if your 3126 won’t start?
Not at all too techie! After trying everything I could think of or find elsewhere on the web, disconnecting the IAP allowed the 3126 to start immediately, but run just a little ragged. Reconnecting the IAP afterwards, while running, the engine smoothed out and continued to operate normally.
What kind of oil does a cat 3126 take?
By the way my engine in Serial# HEP 280486. I tapped into the high pressure oil galley and put a 4000 psi gage in. Had a helper crank the engine while I watched. The pressure started up kind of slow and then quickly headed toward max on the gage.
What was the problem with the Caterpillar CAT C7 engine?
The ACERT Technology had a lot of problems for Caterpillar, first with the CAT C7 but more so later on with the CAT 13 and CAT 15 engines. The technology was really the first generation emissions technology for heavy duty diesel engines. The ACERT technology was prone to numerous regeneration issues. Drivers reported low power and low fuel economy.
What are the connecting rods on a Caterpillar C7 ACERT?
The connecting rods in the Caterpillar C7 ACERT are not forged, liked the CAT 3126, but consist of powdered metal with a fractured cap design. There are also various sizes and configuration of the connecting rods depending on the piston used in the engine.
What are the fuel pressures on a cat C7 ACERT?
The fuel change dictated that the fuel system of the CAT C7 ACERT needed to change to a common-rail injection system. The new common-rail injectors took injection pressures to 25,000-27,500 psi. The fuel transfer pump supplies the fuel to the fuel rail at 280 psi.
