SuiteSuccess Posted October 23, 2015 Report Share Posted October 23, 2015 After replacing o-rings and collets twice, I still have leaks in my 3/8" lines. Has anyone replaced their pass thru (the black panel in the pic) on their Volvo? If so how much is the part and how hard a job? 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

oletimer Posted October 23, 2015 Report Share Posted October 23, 2015 Suite, I replaced mine the summer of 2014, along with the dash air valves, and engine pass thru wiring harness. Actually, I chickened out on the wiring harness after looking at it and not being able to figure out all the connections. Then after taking it to the dealer, found out it was the wrong harness. So much for the "last 4 of you're vin please" ending the possibility of mistakes. Anyway, the air manifold wasn't to bad, and I'm glad I got it done, not sure if I would have had the patience to do the rebuild, even if I would have known about it. I not sure about the cost right now, but I will check it out and let you know. I think it was around 350-500 bucks. If I can locate the invoice I'll edit this log with the correct amount. Didn't solve all my leaks, but helped a bunch.

oletimer Posted October 23, 2015 Report Share Posted October 23, 2015 Suite, After checking your picture closer, I think we might be talking about a different pass thru. The one I replaced had 3, 1/4" lines plus 3, 3/8" lines, plus room for some more. I was also off on the price, the invoice shows a list price of $147.54, but I got a discount so price was $95.90. My dash brake valves were $512.46>$333.10. At that time I also replaced the cab leveling valve, $95.83>$62.30. Wiring harness ended up being list price because of shop install @ $996.48, + about $850.00 labor. No more oil all over the starter though.

SuiteSuccess Posted October 23, 2015 Author Report Share Posted October 23, 2015 Thank you ole timer. This weekend will look from inside and see what's involved. May be more than I should tackle. The part I'm talking about has the red, green, orange, and black lines as well as an electrical plug with all the wires. It does look like it just unscrews though. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

Alie&Jim's Carrilite Posted October 23, 2015 Report Share Posted October 23, 2015 The electrical plug has an allen screw in the middle of it. Remove the screw and the plug should wiggle out.

ray.service Posted October 24, 2015 Report Share Posted October 24, 2015 Don't know when they changed but the "older" part has been replaced by 20990666 which has a different layout of the air lines. Could be confusing and tedious. I have the new one I ordered off Amazon for $102.79 in the cab of the truck just waiting as the next project. The fittings have their function molded into the plastic on both the old and new but haven't checked whether they match. If you do have the old style and do this before me please let us know how it goes.

SuiteSuccess Posted October 24, 2015 Author Report Share Posted October 24, 2015 Ray, Gonna try one more time with new collets , hose, and O-rings before I take the pass thru out. If I do change out will post. 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

Brad & Jacolyn Posted October 25, 2015 Report Share Posted October 25, 2015 Carl I have been thinking about this and I wonder if the air line ends are cut square. I have also wondered if it would help to slip a small screw driver blade under the edge of the collets when you push the line in to help hold it out and maybe make the fit against the O ring a little tighter. Just curious if this would help cure the problem and then I could use that solution in the future. Always trying to help.

SuiteSuccess Posted October 25, 2015 Author Report Share Posted October 25, 2015 Thanks Brad. Gonna work on this this afternoon. Gonna replace the hoses, o rings, and clean out the connections with air to be sure no dirt or other build up. I was careful being sure hose was cut square. Also inspected the original o rings when I replaced and they were intact and didn't seem to have any chunks missing. Will report later on progress.

SuiteSuccess Posted October 25, 2015 Author Report Share Posted October 25, 2015 Brad, Did as above and have only one line with minimal leak now. Not enough to warrant replacing whole pass through manifold. Pulled back mat and looked at manifold from cab side and would be a job to replace. Discovered another problem now. Have dampness under mat so gonna have to pull seats and dry out and see if I can find leak. BTW experimented a bit and the hose slips inside the o-ring rather than flush against it as you can see from this Parker cut away. http://www.parker.com/literature/Brass%20Products/Brass%20Product%20-%20Images/BUL.3501%20PTC-QRG.pdf 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.

SuiteSuccess Posted October 27, 2015 Author Report Share Posted October 27, 2015 Got mine from Volvo dealer here. They only had 3/8" no 1/4". Mr. Seas via Brad Dadle gave me a few 1/4" at the National Rally. What size do you need? 2006 Volvo 780 "Hoss" Volvo D12, 465hp, 1650 ft/lbs tq., ultrashift Bed Build by "JW Morgan's Custom Welding" 2017 DRV 39DBRS3 2013 Smart Passion Coupe "Itty Bitty" "Don't go around saying the world owes you a living.
