What's wrong with the pump ? if it is only leaking you can put a new seal in it.

Does anyone have the part numbers for the water pump rebuild items (bearings, seals, gaskets) on a 5U D2 (5U16805)? Any advice on the rebuild procedure is also appreciated.

It sprang a leak this afternoon gushing out the seep hole. We've got to get some work done using this old machine so I need to get it repaired quickly. An image of the parts page for the water pump would be appreciated.

In this photo you can see the full stream of coolant coming out of the hole just below the zerk with a bit of red grease showing.

Ok, I've got all the parts now. The old water pump has been completely disassembled and cleaned up. The deep groove worn in the pulley sheaves are being built up by a machine shop with metal spraying equipment who will deposit new metal and turn down to a nice V-face. That is expensive, but there are no new pulley parts from Cat and it was so worn it really had to be done. The radiator is being re-built at a local radiator shop recommended by an ex Cat dealer executive.

I plan to go up to the farm Friday afternoon and put it all back together and hope to have it running in the field on Saturday.

I've run into a couple of issues that I'd like the experts to weigh in on.

First, the new ball bearings from Cat were junk. I can't turn them by hand at all. I measured them and found 62mm OD, 25mm bore, 17mm wide with the number 6305 stamped in the bearing. The Cat part is a simple open cage bearing. 6305 is an industry standard bearing size, so I picked up a pair of double sealed SKF bearings that are smooth as silk. I was thinking to remove the zerk and put in a second vent plug 4B4550 in place of the zerk so nobody will try to grease it. It doesn't appear that coolant can reach the bearing given the shaft drain slot, conventional seal and bearing seals. Am I thinking wrong here? Should I stick to the 60 year old design or put in a good modern bearing?

Second, the impeller 4F4770 is worn on the face that rubs the seal on the bellows assembly. I've measured a step around the perimeter of the sealing face on the impeller about 0.030" deep as shown here.
[attachment=24902]5U16805_4F4770T.jpg[/attachment]
The impeller diameter increases to form a sort of collar at the sealing face end of the impeller. The collar section is about 0.43" long. If I turn the sealing face to remove the rim (and no more) the collar would be 0.40" long. What I'm calling the sealing collar is shown in cross section in the parts drawing from this thread under the head of the arrow for part 5F9140, but the collar is part of the impeller 4F4770.

Should I
A) Assemble as is without any machining of the impeller
😎 Face off the end of the impeller on a lathe to be flat and true with no rim, making the sealing collar section a bit shorter than 0.40"
C) Build up the material worn down before facing off the end (e.g. using a TIG torch and bronze filler rod in the hands of a world class welder - not me)

I'm leaning to option B.

Thanks,

Joe
