CAT 249D 100-1 code

[Jerry Lister]

Have a 2017 CAT 249D track loader. Got the following error shortly after startup. Can you give me some direction on where to start looking? Any help would be greatly appreciated.


Thanks Jerry

Nothing immediately pops up but there are 10 different flavours of 249D. Post a Serial Number to dig deeper.

EDIT: The first thing would be to check the engine oil level. Did you do that and where was the oil on the dipstick.? Also was the machine on level ground when you checked it.?

Hey Nige the oil looked OK. Not sure on the level ground. I will check again this AM.

Thanks Jerry

The reason I asked about the ground being level is the following comment from the O&M Manual - "If the machine is operated on severe slopes, the oil level in the engine crankcase must be at the "FULL" mark on the dipstick." So if you pulled the dipstick on less than level ground you could have seen a false oil level reading.

Also see attached. The first possibility it mentions as a cause is low oil level.

Hasn't been operated on big slopes. Machine is on level ground and the oil is full

Got the pdf on what to check. Oil is not Aerated so guess I will do an oil and filter change first and go from there.

Take a close look at the oil when you drain it. Does it look "thin" and/or smell of fuel.?

Will do

In addition to that pay close attention when you refill the oil to get it bang on the FULL mark, then keep a close eye on whether or not the oil level is goes up at all over time. That would indicate fuel getting into the oil pan from somewhere.

Did you change oil recently? Is that a logged code are an active one?

You will get that alarm on all Cat excavators after you change the oil and it takes a couple of seconds for the pump to pick it up and fill the oil filter. There is a place in there where you can see the actual oil pressure while you are running.
