When I had one semi-collapsed accumulator on my '85 wagon, the ride was fine with no load but when I towed my sail boat the ride became very bouncy at highway speeds. Replaced both, problem solved. I compared the old and new by inserting a rod to see how far down the rubber diaphragm was, the decent accumulator was less than an inch in difference, I think I remember like a 1/4 inch difference. The 'bad' one was about 1.5 inches or so.
I used a lift for that job, had a couple new bottles of hydraulic fluid on hand and the proper flare wrenches. Took less than an hour. Andrew, when you raise your house to install that two-pole lift, I'll bet you can get your time down to 20 minutes or less! -Max -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Fmiser Sent: Thursday, April 22, 2010 1:27 PM To: Mercedes Discussion List Subject: Re: [MBZ] Changing 300TD air cells (accumulator spheres) - anyone BTDT? > andrew strasfogel wrote: > I am not yet convinced without further inspection that faulty > sphere()s is(are) the root cause of my jarring (as opposed to > bouncy) ride. A jarring ride is the definition of failed accumulators. My experience is: the highway expansion joints are not especially noticeable, but even fairly gentle dips feel like someone is hammering the seat. A rough road can make you want to wear a kidney belt. Altogether not unlike the brutal ride of an old, empty one-ton pickup. _This_ is what accumulators will solve. If the ride is bouncy, then the damper (shock absorber) part of the system may be at fault, but I have never experience that. Both cars I have done rode nearly as rough as a metal-spring cab-over big truck running bobtail - but there I had an air-ride seat! With new accumulators, the ride is just as good as my sedans with conventional suspension whether the wagon is empty or overloaded. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
