Grahamgl Posted September 4, 2023 Report Share Posted September 4, 2023 Gentlemen, Can someone please advise me if the thread type on the three mounting studs is either 3/16” UNF or 2 BA. Part number 17H5431. Thanks Graham Quote Link to post Share on other sites
BlueTR3A-5EKT Posted September 5, 2023 Report Share Posted September 5, 2023 The repro studs I have are 2BA and screw into the wiper motor gearbox case without a struggle. That does nor mean they are right. My definitive 10-32 unf thread test is with an unused 10-32 unf bolt from a GE aeroplane engine. That bolt is too big for the Lucas wiper motor gearbox. I have sent an enquiry to a friend who worked for the manufacturer of the repro studs and await a reply. Peter W Quote Link to post Share on other sites
