rickeieio Posted November 9, 2018 Report Share Posted November 9, 2018 Hmmm... Long time ago, I had a fuel pressure gauge on a tractor, and the needle would slap back and forth like a fish tail. I put in a brass thingy that dampened the pulses and the needle was steady. I think I know where that brass thingy is hiding in the parts bin, and I have some fittings in the air line repair box.............

Lance A Lott Posted November 9, 2018 Report Share Posted November 9, 2018 Yes you could buy slip on fiting and fill them with lead or braze them and then put in new o rings and then drill a small hole in the fill material and then drive some one elses truck to see if you got the right size hole and keep trying until you get it correct. I obviously thought about it but I have no one to go too to see,if I got,it right. They have a mony back guarantee so I decided not to reinvent the wheel. Now that they are in I think they deserve to be paid for there time and effort. And even though I could measure the hole and now make my own if I was to buy a different truck I would just order them. Every time I drive the truck I think about those stupid little valve that don't move or do anything and I think that I may have never spent my money any better.

Reminds me of the old 4020 fuel gauge....It's electric but do you think if I could stop the fuel gauge from slapping like a fish, the old girl might act 18 again?

GlennWest Posted November 9, 2018 Report Share Posted November 9, 2018 Most folks kick on the driveability of front air axle. I do too. Mine checks out good and fight to go straight down the road.

Norm & Rhonda Posted January 20, 2019 Report Share Posted January 20, 2019 The Volvos with the front end air ride are a different breed. When I first got mine I had never experienced that type of feeling on any other truck I have driven. Yes I have in the past driven trucks that were plum wore out but the drivability was just plain different. The Volvo Front Air Ride is a small learning curve to get used to but it can be done. Like mentioned above the Sleeper sway does add to this road feeling. For something as easy as installing a couple of sets of Donvel Valves I can definitely attest to this being money well spent. If you don't have a good experience with the valves (which I highly doubt) send them back for a refund all your out is a couple of bucks for shipping. I love my Donvel Valves.

alan0043 Posted January 20, 2019 Report Share Posted January 20, 2019 Hi Everyone, If you were going to put Donvel products in your truck. Where would you put the first set at ? Suspension ?

Darryl&Rita Posted January 20, 2019 Report Share Posted January 20, 2019 Why would you pay for shipping multiple times? Order enough for all, install, enjoy. Don't enjoy, remove and return.

Lance A Lott Posted January 21, 2019 Report Share Posted January 21, 2019 I put the valves on the rear bags (existing bags), cab and seats. My Volvo does not have front bags. If I was going to do it one at a time then I would use this order. Cab, seats, drive axles. But for $300 or so it was easy to do all three at once. If your tandom it will cost another hundred or so.

I can only do a section of the truck at a time. I need to stay in budget. Front axle, cab and your choice on seats or rear axle next. Front axle first to address the understeer and softness feelings. Cab to minimize the swaying but this seems more benificial to the larger cab models. Seats are not a biggie but it probably depends on the brand of seat you have and how you adjust them. Rear bags seem to be a function of individual setups. I have all of the bases covered and found the front axle and cab valves returned the most noticeable results.

lockmup68 Posted January 24, 2019 Report Share Posted January 24, 2019 Brett Wickert, who is active on HDT forum on Facebook, put them on his Volvo and did an extensive writeup, testing, different valves, and retesting, working with Donvell, etc. Very good information with before and after test results. 2003 International Eagle 9200i, Cummins ISX, Freedomline 2007 Teton Scottsdale XT4 Link to comment Share on other sites More sharing options...
chief916 Posted January 25, 2019 Report Share Posted January 25, 2019 Well I bit the bullet and just ordered my first valves for my rear springs. Once it gets a little warmer I plan on ordering the front steer bags. Robin at Donvel was a big help and very informative. Its gonna be interesting to see how this suspension upgrade will perform. what I do know is that with the suspension I have now, I most definitely WILL NOT drive through Indianapolis. Stay tuned (no pun intended) Ben Link to comment Share on other sites More sharing options...
