Default Curious opening on Power steering pump

Hello, we are new members and this is my first post and I want to thank everyone for the warm and helpful welcome we've received so far.

Here are a couple of questions if anyone has feedback: In opening up the front for tracking down a coolant leak which I've discovered is coming ( I jury rigged a long top coolant hose as the radiator is swung open) from behind the pulley shaft directly above the crank pulley on my 3208 which I'm assuming is the engine water pump, I discovered what appears to be the source of a chronic power steering fluid leak- a threaded hole in the top of the power steering pump completely open though it is a threaded opening and fluid is visible just below the opening (as well as distributed all over in the vicinity). There is no sign of any plug or hose fitting. I'm reluctant to just install a tapped plug in case it needs a vented one or something else.
Does anyone know what should be in that hole? I can't believe it is meant to remain open!
Next, does anyone have a suggestion of a source for a new or rebuilt engine coolant pump? I'm afraid to know the price.
Thanks in advance for any feedback,

I forgot to mention that we have had our Bird for three years, 35,000 miles and lots of mechanical adventures but she's never let us down and always gotten us there and back!

get a rebuilt pump from the CAT house.
then you have a nationwide warrenty for the part,in case it goes bad.
I;m sure you need to put a bolt or plug in thePS pumps hole.
a pic sure would be nice!

Default CAT house

Randy, I'm guessing the CAT house is my local Caterpillar dealer?

If I did it right there ought to be an attached picture of the hole thing!
It sure doesn't look right does it

thanks , jb

Yes, the CAT house sometimes refers to the caterpillar dealer, I also use that term to refer to the doghouse that my CAT engine sits under in my 'Bird. Make sure that when you are going to purchase that NEW pump that you have the engine serial and arrangement numbers for your engine with you, as they will ask you for them, here is where mine are located;

I believe that there should some type of a plug in that hole, but let Randy comment on that. There can however be a very small vent hole drilled into cap/plug for the power steering fluid reservoir, if there isn't already one there.

I would also replace the power steering fluid and the filter in the power steering reservoir since the plug that is missing on your pump probably has allowed dirt to contaminate the power steering fluid. If you have a reservoir like the round black one at the bottom of the right picture above, the part number is CARQUEST 85430 or NAPA 1430

John, I sure am glad they put that plate where you could see it, LOL.

I do appreciate your feedback, it hadn't occurred to me to change the psp fluid and filter but it is excellent advice, thank you for that and the filter #s.
I sent the photo to Glenn Rogers ( at BB) of the psp hole to see if he has whatever goes in there.
On the engine water pump the local Wagner "Cat House" (Hobbs 85 miles) will have it for me here on Friday @ $172.85 after the core charge. They have a drop box at the bus station. Yup, this is a mail-order town.

Good luck on the repair and be sure to read Caterpillar 3208 belts part number s and Adjustment proceedures

It would probably be an excellent time to go ahead and replace the drive belts, since they will be coming off to change out the water pump and you want to make sure that when you do the installation that you follow the adjustment procedure, so that you won't have to repeat the whole procedure all over again.

JB,
we jokingly call the CAT dealer the CAT house!
and,i also call the "Dog" house in your coach (the engine cover) the CAT house,after all,a cat lives inside!
The PS pump sure needs a plug in that hole,maybe someone else has a pic so we know what the plug looks like.
Randy

John and Randy, thanks for the encouragement, I'll be sure to keep you posted.

Would you replace belts if they were less than three years old?? I have no idea how long a belt lives inside a Cathouse!
jb
ps I'm hoping someone comes up with a definitive answer on that plug.

Hey John Barry,

Is this alias Musical Whistler John ???

I got a peak at the power steering pump on our 88 FC.
It appears that you are missing a plug, It also has the model # on this cap. But, I can not read the numbers.
This may be a place to perform an adjustment or monitor a pressure when testing the pump.
Good to see you posting and asking questions.
