I hope one of the CAT guys can help me here, I am on SIS WEB attempting to look up parts for the first time and having trouble finding what I need. I can find the return tube but not the pressure line and fitting... The graphics I come up with show a tube, not a hose.

 

It's a 2001 F650 with a 3126B engine:

 

I need the high pressure oil line from the HPOP to the cylinder head and the fitting at the pump. This is the 8" rubber line with the quick connect ends.

  • Arrangement #8YL

    .

  • Serial #0083806H

Keith if line is leaking or loose at fitting on pump, replace pump. Once that fitting starts to leak it will come back, the pump thread will feel ok and tighten up, not leak when you have it but will eventually blow off on the customer. If the pump fitting is not leaking or loose you will be all set, just follow the instructions and replace all parts in instructions.

Thanks Tim! The fitting on the pump is not loose as far as it's relationship with the pump itself. My impression is that the hose feels a bit looser on the fitting than I would like. If I am going to be upgrading this to a steel tube then the fitting is going to be replaced anyway. Good advice though! We have had problems with those fittings loosening and blowing out the o-rings on the pumps on 7.3L engines. The fix was new o-rings and Loc-Tite on the threads.

 

What would be a fair labor time for this repair?

What would be a fair labor time for this repair?

I checked time requirement guide, heui tubes, 1-1.4hr. So I would say 1-2 hours but if it is not warranty, you could fairly charge for diag and installing an update that eliiminates problem, taking care of customer. 3 hours???

I went with 2.5 - includes diag, time to look up the parts and I will wash the engine when done. I was able to get the kit yesterday as CAT had it in stock. Looks straight forward and aside from that the customer wants a few service items taken care of so its all good.

Larry, for us it makes no sense to stock any CAT parts beyond filters. We are a TEPS dealer with no authority to perform any real repairs to these engines. I have enough information and diagnostic equipment to determine whether a concern is a Ford problem or a Caterpillar problem and decide who gets to perform the repair. Sure, we can do some small repairs and we are free to perform out of warranty repairs, but since we have no special tools, only see a handful of concerns per year it makes no sense to stock anything - especially with the current economic conditions. Whats more is that it would cost too much to become a certified CAT service dealer and with CAT dropping out of the on-highway engine business in two model years it's pointless.
