    Cat 973 fuel injector pump - no fuel

    Makes sense when reading the manual. Great advice. Doesn't cost a lot for a few aftermarket gauges and no doubt some would be better with different length hoses. Assume 600 psi might be an odd range, so my choices might be limited. Being retired and this a restoration project I can progress...

    Cat 973 fuel injector pump - no fuel

    Yeah, sorry about that. Did a search for 6V4157 on the Internet which came up with 1U5796 on ch-part.com. Jumped in without reading closely and also because a lot of the procedures in HT System Operation, Testing & Adjustment manual (SENR5365 Mar ’95) mentions differential pressures. The...

    Cat 973 fuel injector pump - no fuel

    Thanks for that info, Nige. I started this before the last ½ doz posts, but I’ll post it anyway. In regard to working thru the procedure for troubleshooting and setting up the hydrostatic transmission (HT): Are the test nipples on the hydrostatic transmission the same as the nipple on the fuel...

    Cat 973 fuel injector pump - no fuel

    Thanks for bringing that to my attention. You think you've read something accurately, then continue the error. Can't call it a typo ... keys too far apart. Oh well, least I didn't use Kmart. :)

    kubota SVL95-2S shop manual

    I have a copy of the WSM for the SVL75 and SVL90, Code No. RY911-20821, issued 02, 2011. Do you specifically want one for the SVL90-2 ? Start a comversation.

    Cat 973 fuel injector pump - no fuel

    Ordered 8T5287 - bush wrench and 8S2244 - bonnet extractor, today from DCT, Castlereagh. Not much more than ½ price of the main Cat dealer ... about $75 posted. From this picture found on the Internet, it's apparent from the machined face, that the pump must come off the front gear housing to...

    Cat 973 fuel injector pump - no fuel

    Good enough for me. Don't like it when a socket or spanner tips off a fastner. Is the gearing so fine that you couldn't judge that the slot in the plunger gear was going down the bore close to where it should be ? No experience here, just my own perception from the service manual pictures...

    Cat 973 fuel injector pump - no fuel

    Just realised I hadn't answered your query while deleting notification E-mails. Machine Hours - Don't remember the figure, but I recall thinking unremarkable. The machines has been sitting for maybe 15 years. That makes it 15 years younger, wear wise, however the exterior has been knocked...

    Cat 973 fuel injector pump - no fuel

    The service manual says the spacers (shim) are the same size for each FI pump. Also there is an O-ring between them and the bonnet. For the stroke length of the plunger to be fixed, I assume the O-ring is NOT pinched between the spacer and bonnet, but sits adjacent. However I'm a bit OCD about...

    Cat 973 fuel injector pump - no fuel

    Thanks very much. That picture of the Cat tool (8T-5287), alone, tells me so much - “picture worth a thousand words”. I know if you haven’t got the image handy on your computer it’s a rigmarole to post it in the forum. Thanks for your effort. And yes, I “aint getting it fixed without them”...

    Cat 973 fuel injector pump - no fuel

    Another ½ day on the Cat 973 Another ½ day on the Cat 973 Accessed the rack at the pump timing access cover. Had to take the battery out and get my head right down low to see it. The slot in the rack was at the very front of the window (cf the photo below). Got a big screw driver in...

    Cat 973 fuel injector pump - no fuel

    That's helpful. When I took the rear governor housing off, I was able to grab the end of the governor servo valve and give it a tug. it only moved a ¼" as if it had that much free play. I wondered whether I was putting force directly on the rack by pulling/pushing on the valve. Considering...
