[Reference] Dashpot Throttle Damper Dimensions
« on: February 15, 2012, 22:56:41 »
Here is a picture of my dashpot damper on my 69 280sl.  I have been told you cannot get them any more. But here are some possible replacements part numbers.  Special thanks to 66andBlue for providing this.

The measurements on this particular dashpot are A=2 1/32"     B=1 1/8".

There is not an exact part that fits these dimensions but some are close enough. I have not tried any of these yet.

Two years ago I bought one from Buick Farm (www.buickfarm.com).  I have no clue how I ever found it but it is listed as a throttle linkage dashpot w/bracket for a 1962 Lesabre.  I checked the site and the part number is no longer available but perhaps it can be found elsewhere.  The picture below shows it installed.  I will have to go out and check the measuremenst but it seems to be working fine and it fit perfectly.

To me it looks like a Pierburg dashpot (see the photo), but which one is the big question.  I get the impression they come in many damper configurations.  It's probably not even critical,  It's only to keep the deceleration manifold vacuum from spiking on closed throttle and to let the throttle down softly.  High vacuum spikes cause incomplete combustion in the cylinder and therefore backfires in the exhaust system (and bad emissions, for you tree huggers).
The one in the photo is for an old Saab and the part number is W01331619541APG.  It pops up everywhere on the internet if you search that number.  I wish I knew more about it.

I searched and tried to order one of the Pierburg CAD plated ones for a couple of hours and couldn't find one that was available to me in Canada.  So I ordered the DV60 dashpot (second row center) from the following site.

http://www.autopartsobsolete.com/Parts-by-category-or-use/Fuel-System-Parts/Carburetors-amp-Parts/Carburetor-Chokes-Dashpots-pulloffs/     Click on the photo to get the DV60 designation.

Since I'm not sure whether cad plating it would damage it, I'll just paint it yellow cadmium color and hope it disappears in all the other cadmium plated parts.  They've got one left after my order.  Pretty cheap, huh!

I had some parts plated and anything that had a vaccum cell or a place to retain fluid was pretty much ruined. I guess the plating solutions are acidic because everything was full of rust so I would have been better off painting these parts.

 The plating looked nice though......
