moontownMooney Posted October 26, 2019 Report Share Posted October 26, 2019 Can anyone offer any information regarding the o-ring that holds the rubber servo boot in place on the fixed servo base of the step retract vacuum servo. I have a '68 M20F but I would expect it is similar/same for any model with a vacuum step retract servo. Ours has broken and I need to source a new one. Any info on vendors, part number, material, or dimension is appreciated. Sent from my LM-V405 using Tapatalk Quote Link to comment Share on other sites More sharing options...
RLCarter Posted October 26, 2019 Report Share Posted October 26, 2019 I don't see the o-ring listed in my parts catalog, take you old and have it matched and your favorite o-ring store Quote Link to comment Share on other sites More sharing options...

RLCarter Posted October 28, 2019 Report Share Posted October 28, 2019 @moontownMooney no dice on the specs for the o-ring, might give Brittain a call and see if they can help Quote Link to comment Share on other sites More sharing options...
moontownMooney Posted November 20, 2019 Author Report Share Posted November 20, 2019 If anyone is interested, I was able to get all the details from Cecilia at Brittain. They use a Parker P/N: 2-042. This is a standard "-042" size o-ring meaning 3.25" ID, 3.375" OD, 1/16" bead width. It should be made of N674 compound with a hardness if 70 (N674-70) or equivalent or better. They use Seal Company Enterprises of Tulsa, OK. I found a suitable part matching these specs at www.theoringstore.comSent from my LM-V405 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
