International Tech Posted April 25, 2006 Share Posted April 25, 2006 Hey guys and gals. This is my 1st post although ive been cruising here for awhile. I just wanted to give a heads up on 05-06 engines having a no start w/ low or no ICP. After having 3 last week and 3 more sitting on the lot waitin on parts and talkin to an engineer, We are starting to see branch tube failures at the coupler to the HPP. The couplers are blowing out and bending/ breaking the branch tubes. Theres is a fix for this but unfortunately you still have to replace the branch tube assembly. Ill post the kit part number later on today. /forums/images/%%GRAEMLIN_URL%%/thumbup.gif Quote Link to comment Share on other sites More sharing options...
gasgasman Posted April 26, 2006 Share Posted April 26, 2006 I've done a few of these. TSB 06-4-6 5C3Z-9C854-A H/P Discharge Tube W301727 H/P Pump Outlet Fitting The coupler "vibrates" with the high pressure oil pump pulsations. This causes the o-ring to get chewed up and leak. Not a very well engineered connection. Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted April 26, 2006 Share Posted April 26, 2006 Tech in the next bay had an interesting one... no starting concerns but there was a strange noise, almost a buzz off idle... Loudest around the HPOP... no starting concerns. He replaced the branch tube fitting and all was well.... Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 26, 2006 Share Posted April 26, 2006 Noise? I had some HPOP's make a rattling sound a while back but I could swear I read somewhere that these disconnect fittings/feed tubes were rattling against the rear engine cover. TOOBADQ sent in some pics of one that broke the rear engine cover. I'll post them when the server ordeal is complete. Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted April 26, 2006 Share Posted April 26, 2006 I don't recall the tech mentioning any witness marks on anything... I do recall him and the shop foreman dwelling on this noise... even me with my tinitis could hear it... Funny thing is, in the shop, at least, it appeared rpm specific... (remember, I'm trying to do my own stuff and eavesdrop at the same time... some stuff is hard to miss since my tool box is an occasional "tool crib" for some of the more esoteric tools). Check the "water cooler for an announcement... oh, and check ALL of your e-mail addresses, I sent you an interesting tidbit a couple of days ago...

International Tech Posted April 26, 2006 Author Share Posted April 26, 2006 THe kit i mentioned comes w/ a bracket and bolts. The bracket bolt to the front 2 bolts of the HPP and the 2 bolts of the disharge tube to help keep things in place. Ive put the discharge tube and fittings on only to have the same thing happen and bend the discharge tube backwards and sheering off the bolts to the coupler. From then on i said im putting a discharge tube and the updated kit on no matter what. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted May 1, 2006 Share Posted May 1, 2006 Here's a little more info for you fellas: I called the Tech Hot Line and the engineer (Al) knew what I was talking about and said that the bracket was being evaluated and was not yet approved for use by Ford... he then asked me to hold. He comes back and stated that the kit HAS been approved and the kit will be released sometime this month (May 2006) possibly early. The part number is 4C3Z-9B246-A which should contain the connector, fitting, seal, bolts, bracket and an instruction sheet. Good heads up! /forums/images/%%GRAEMLIN_URL%%/thumbup.gif Quote Link to comment Share on other sites More sharing options...

International Tech Posted May 10, 2006 Author Share Posted May 10, 2006 here it is 1873821C91. It shows up on our parts online that it is unavailable. We have to call our V-8 engineers to send us this kit. Quote Link to comment Share on other sites More sharing options...
Raptor Posted May 11, 2006 Share Posted May 11, 2006 Thanks i'll try calling Fords Diesel engineers to see if I can get the part that way. Our parts department got a fax from Ford that said it wont be available until June. Quote Link to comment Share on other sites More sharing options...
Raptor Posted May 19, 2006 Share Posted May 19, 2006 my service manager just talked to Ford and they said the bracket kit won't be avaiable until Decmber! Looks like i'll be doing repair without bracket!! Quote Link to comment Share on other sites More sharing options...
International Tech Posted May 21, 2006 Author Share Posted May 21, 2006 Huh?? Is there anyway you can get in touch w/ someone from International? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted May 21, 2006 Share Posted May 21, 2006 Huh? is right! I was under the impression that these would be available within a month or more likely two - June. December is a long way off and I am seeing more of these things fail than I care to. Considering the fact that this kit was already conceived and some available, how long should it take to ramp up a production run and post a TSB? /forums/images/%%GRAEMLIN_URL%%/mad.gif Quote Link to comment Share on other sites More sharing options...
pcassidy111 Posted May 23, 2006 Share Posted May 23, 2006 This buzzing noise, is it pretty noticable on decel at freeway speeds when the fuel is shut off? I test drove one of our fleet account trucks (2005 F450) on the freeway and heard a buzzing noise, not the normal 'air pump' noise on decel. Don't have a bidirectional Ford scanner so I cannot test as directed in the TSB but I would like to inform them of a pending problem if one does exist. There are no starting problems with this truck, 1-2 seconds of cranking hot or cold. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted May 24, 2006 Share Posted May 24, 2006 I never did think to ask when else the thing buzzed.... I do know you could hear it in park at around 2000 rpm (I think). Quote Link to comment Share on other sites More sharing options...
