do yo know the part # for this seal?

Hello IRNWRKR

You asked for the Cat part No's for the injection pump gsket etc, they are -

Gasket - 2A 3337. Ferrule (seal) - 2A 3855 . Hope this helps.

Taken from Parts Book, Form No 8126. for 4G1 to 4G 9999 inclusive

Check those part numbers again....2A3855 is the ferrule.....2A3854 is the seal (barely shown on the injection pump assembly in the parts book).

The loss of this seal allows fuel to migrate to the crankcase...not likely the cause of a flooded sump in the fuel injection pump housing. More common to find that caused by leaking injection pumps (barrels & plungers) and a plugged up drain. Also make sure the drip shields for the lifters are in place. They are there to prevent fuel from dribbling down on the lifters and winding up in the sump.

Ok went out and found my new seal. It has a different part number on the bag 8B4967. It measures OD 1.4" and thickness of 0.2" Fits on the ferrule nice and tight.

jmvmopar's part #8B4967 is a valid Cat number for that seal, at least that's what my D2 parts books show (5J and 5U), D4 is probably the same. I've taken that number to Cat before and had no trouble.

I don't have any D4 books but maybe 2A3854 must be an earlier part number for the same component?😕

Yes, that most likely is a replacement number.....just important that you start out with a correct number....the computer will upgrade to the latest version.

thanks for your help!!!!! om, those drip deflectors, what do you look for when checking for that?

I saw the drive shaft seal on page 122 of my engine manual, but mine does not have that, there is just the brass bushing and no recess in it for any seal.they must have added the seal at a later time.
