I was documenting the whole process to post, because I wasn't finding much for info when I went to do it. Even the repair manual is woefully inadequate and I paid good money for that sucker. I was looking at ports, making sure everything externally lined up... the one thing I did not think of was the drive... because I was buying a brand new pump right from CAT....Where is the pic of the one that came off?? :blob1:
is it similar/different??
Phluck
I'm just hoping the old pump is still at the dealership 2 hrs away on Monday when I call... if the right pump is unobtainium, I'll need it to rebuild...
Yea... nothing like having to learn the hard way. A little explanation in the manual would have been a good thing. I've seen John Deere manuals that walk you through the whole process from hood removal to sheet metal replacement. I found out I was trying to access the last bolt on the side panel the wrong way too. I think that one just might get a new access hole with a cover plate before I put it back together.
In this case there really is no language. That pic I posted is all the information in the manual about water pumps. Even if it had been labelled as 2 different part numbers or with/without air brakes it would have served as a heads up in terms of what to be aware of.
You made me dig back through the manual and you're right... that pic I showed was from "Specifications". Nothing useful in "Testing and Adjusting" other than a repeat of the belt tension chart and instructions on how to install a thermometer for testing temps... not my problem. There are more pictures in the "Disassembly and Assembly" section, but it wouldn't have helped me. They tell you to remove the hood (you really don't have to) and while the external pics show a unit with the air pump (of which there are also 3 versions) , all the internal pics are of a pump without the spline drive. It's just a rehash of the useless info in the first section.
It's not really his fault, and my machines are older than he is. When he looks at the parts breakdown of the 2 different numbers, they show all the identical parts inside, which really doesn't make sense either. 1st pump was 2 weeks away, 2nd number is only 3 hrs away in Winnipeg, so hopefully something works out. If it turns out to be another lame duck I'll get the kit and rebuild the core. So much for ordering a new pump because it would be faster...
I was thinking about that too.... it could happen yet. The problem is that the 2 pumps were 2 hrs apart when I discovered the problem. It turns out the "right" pump in Winnipeg isn't there, but they did have a rebuild kit. If there is anything wrong with the impeller or other internals on my core, we could be doing the internal swap as you suggest...
Turns out the "on again, off again" "right" pump was there after all. They have it at the shop to compare and they're pretty sure it's the right pump this time. I've got a funeral tomorrow and had an appt. today so I'll get up there Friday to pick it up... 4 hrs round trip so I'm hoping the weather co-operates. Put new studs on my Rav today for the trip. A week late and a dollar short...
Did the last minute scramble today to get my snow tires on... my mechanic is leaving for the Dominican for 2 weeks tomorrow morning...
The ironic part is that we waited for 3 weeks for the "wrong" pump to be shipped up out of the US when the "right" ( I hope) pump was sitting on a shelf 3 hrs away. Have to wonder about their inventory control...You're lucky, my Cummins cylinder liner kits were ordered by the engine serial number, wrong. There is 5 different options for liners in this engine, after a bunch of measuring and relaying info the parts guy says "Oh, you have one of those"
