D330C
4B1888 Industrial
Old Magnet, do you have any idea of where we could locate a a used or rebuilt water pump - CAT 7L0144. We have looked everywhere on the internet and locally. Our CAT dealer is unable to find anything new or used. The motor had set for a really long time when I got it. After getting it back running, the water pump was leaking and I had it rebuilt. The builder had trouble finding the correct seal and said the pump needed to be replaced not rebuilt in the future. It did not leak for a couple hundred hours after the rebuilding of the motor; Started seeing antifreeze coming out of the bottom of the pump and now I am getting some water in the motor.And I ned to come up with a fix for this as soon as possible.

I'm not finding anything. Apparently the 7L0144 pump is unique to the early D330c and D333c Industrial and Marine engines only. Along with the 2B/4B/5B prefix engine numbers I also show it in the 66D1 to 8890 and 70R1-up D333c parts book.

Josh, do you show any more applications for that 7L0144 pump in your NPR????

Only other thing I see is 23C, which according to the Cat SN book could be a D333C industrial engine or a 3306 industrial engine.

The following Industrial and Marine engines including gen sets change from D330c to 3304 at these s/n's and prior numbers would have the 7L0144 pumps.
2B4364, 4B6032, 5B1197.

Thanks for all the help and effort that you all have put into this. I hope I can find a way to resolve the waterpump issue. Never thought that the waterpump would become this big of an issue. I hate to pull this engine out of service over this. Just rebuilt the motor, rebuilt the injection pump, fuel pump, alternator and starter.

Have you tried some of the "old" dealers here in CA? Peterson Tractor, Tenco Tractor, Cashman Cat in Nevada?

Good Luck!

Did you have the part number when you inquired about the pump at off road eq.?
I don't know anything about this outfit but they claim to have a 8S7895 kit for that pump.

Hi Team,
having trouble understanding the style of pump being discussed.
I may have missed where this unit mounts to the timing case. Early "C's" had a pump that mounted on top of the case on the left side, later units had the pump mounted to the front left of the case.
Can only think anything special about the pump in question is it is for a low RPM application and therefore higher output.
It has been too long ago now to be sure if low RPM application pumps were ever available.

Depending on your application--RPM wise-- a more standard pump may suffice especially one from a 6 cylinder engine application.
If this is one for top mounting then I would look at a standard pump from a 6 cyl engine. I would have thought the NPR would have reflected that a low production usage pump would be replaced by a more common unit that was a redesigned unit as the engine was developed over the years.
Such a pump could be P/No 5S6684, as fitted to our Aussie built 17K1077-up No 12E Grader engines, may fit unless the plumbing is radically different somehow that I doubt. Even if it were it may be better to update to a more common setup that has common parts available.
I may be wrong as to the designation but the 17K 1077-up engine has the tin Chevy style rocker cover so would be a 4 3/4" bore engine.

Just some ramblings from a forgetful old mechanic who stands to be corrected, if so take this with a grain of salt.

Cheers,
Eddie B.
