Re: [MBZ] 617 Fuel Filter Bolt
I found the right parts page: http://www.mbpartsworld.com/showAssembly.aspx?ukey_assembly=1082553_make=1103_model=16073=1982_category=24396_trimLevel=20574 The bolt in question is item #38. They only show one available seal ring (#41) so I have to conclude that my old TD had some kind of special bolt or that the old-style hollow bolt was replaced with a simpler design at some point. > -Original Message- > From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of > Scott Ritchey via Mercedes > Sent: Tuesday, February 23, 2016 4:36 PM > To: 'Mercedes Discussion List' <mercedes@okiebenz.com> > Cc: Scott Ritchey <ritche...@nc.rr.com> > Subject: Re: [MBZ] 617 Fuel Filter Bolt > > Dan, Thanks for your offer but I believe current-inventory bolts are just > like > the one I have now.

Re: [MBZ] 617 Fuel Filter Bolt
Dan, Thanks for your offer but I believe current-inventory bolts are just like the one I have now. Somehow I missed your link to the parts diagram. Sorry 'bout that. I'm not sure that diagram shows this specific bolt but it is the one in the center of the bracket that holds the "spin-on" type fuel filter. Here's a photo: http://kioti.dyndns.org/bolt.JPG You may note deformation of the bolt head from excessive torque needed to get that metal washer to seal. In the past I had a '79 300TD and the same bolt in that car had an additional groove and O-ring that made a perfect seal with the bracket every time without excessive torque on the bolt. I wish (now) that I had swapped bolts before I sold that car. The thing I was curious about was (1) did my 79 have some after-market bolt or was it a MBZ design change to eliminate the O-ring in favor of the aluminum washer? And (2) was it possible to scavenge (or buy) an old-style bolt with the O-ring that seals with the bracket. I don't plan to remove my current new-style bolt until I must, because it's such a pain to reseal. That will probably won't happen until my current filter rusts through. I am mostly curious if others have this problem and if they have solved it. This is a very small (but vexing) thing in the grand scheme.

Re: [MBZ] 617 Fuel Filter Bolt
You can usually get packages of aluminum or copper washers of various sizes at a FLAPS intended for oil drain plugs. That might at least provide a temporary solution unless the washer in question is something special. If I buy an oil filter from the local Honda dealer for my wife's car, it always comes with a new aluminum washer.

Re: [MBZ] 617 Fuel Filter Bolt
I know what you’re describing, as my 1982 300SD had the same thing. Is it possible to “re-anneal” the washer? Didn’t someone describe how to do this a while back , or was that for a copper washer? Look at this drawing and tell me which one it is. I can check and see if my dealer stocks them - if they do and they’re cheap he’ll just give me one. http://www.mbpartsworld.com/showAssembly.aspx?ukey_assembly=1082551_make=1103_model=16073=1982_category=24396 Dan > On Feb 19, 2016, at 6:51 PM, Scott Ritchey via Mercedes >wrote: > > This is about the hollow bolt that holds the Diesel secondary fuel filter to > the bracket.

Re: [MBZ] 617 Fuel Filter Bolt
If it comes with the hollow bolt with the extra O-ring (that seals at the housing), I'd be interested. Otherwise, I'll just look for a better/new washer next time I need to mess with it. What I find odd is the bolt in my '79 617 (with the additional O-ring) always sealed perfectly without excessive torque but the "newer" design in my '82 required mucho torque (and several attempts) to stop leaking. Regardless, thanks for the offer.

Re: [MBZ] 617 Fuel Filter Bolt
I think the real problem is the aluminum washers for the bolt. I tried a few on my 617s and had to really crank the bolt to stop "seeping" fuel. I returned to the copper washers and they seal much better with no seeping problems. I guess the aluminum are cheaper, but more of a potential headache. I got the last ones I have somewhere on eBay. My Indie also has them, never asked where he gets them. Best Wishes, Roger Roger Hale Dinnerware Classics, Inc.

It takes a different filter, so the first option is better if you have any spare filters on hand. The banjo bolts do stretch. This is a big problem on the auto trans cooler lines. This is about the hollow bolt that holds the Diesel secondary fuel filter to the bracket. On my old '79 300TD (non turbo), this bolt had an O-ring that always sealed perfectly at the bracket. On my current '82 300SD, there is no O-ring and an aluminum washer (under the bolt head) is the seal. I've reused this washer and it takes a LOT of torque to make it stop leaking. What do we know about this bolt? Was it a (poor) design change to eliminate the O-ring? Do I have the wrong bolt in the SD?

Re: [MBZ] 617 Fuel Filter Bolt
Some filters include a new washer but if I'm honest I haven't seen one in years. A copper washer would do the same job and would be easy to anneal when it stopped sealing.
