wow, I thought the same pump fit all 3 engines...

so... now what??

Found this chart from a CAT manual and I think it applies to 3116/3126 engines. Mine is within these specs but still seems low....

Dang, I wonder if the aftermarket ones made in Brazil are any good?? NEW OIL PUMP 3116 3126 C7 CATERPILLAR 2004497 4964800 20R7247 | eBay

Not what you wanted to see but finding it may have saved your engine. That is a mess you didn't want for sure!

Please Please keep us updated with pics!!! Just curious, but how did you discover this? and I'm wondering if the teeth caught something in between them like a piece of metal?? Anything in the pan??

This is interesting. First off, I watched a video of a guy who owns a motor home with a cat engine. 3116 or 3126. He had low oil pressure at 90k miles and put in a new oil pump and bearings. That fixed everything. My truck idles cold at 40 psi. Cruising cold at 60 psi. Warm idle at 17 psi. All...

Mine did this once... I forgot to close the air tank petcocks.....

I think I'm going to take it apart and inspect/change the pump in a few months when it warms up. First, I'm going to hard plumb an oil pressure gauge to verify my dash gauge. $785 for a new style CAT reman oil pump. Ouch. $250 for a Chinese pump.....nope..

Is this a complex job? I have 50psi cold then dropping to 18-20 @165. I had it to 180 once and full RPM was almost 40. Maybe I'm worried about nothing... My neighbor has a c7 in his LMTV and he has 20 PSI more than me across the board...

is this applicable to the 3116??
