I remember working on early SMD vehicle CT1,2 and CMR’s with these fibre top hat hole inserts that electrically isolated the frames members from one another when bolted together, can anyone remember the correct name and SMD part no !!!! 😳 ❓ Looking to islolate some issues we have with a newer SMD vehicle
Most vessels have a lathe, you could get the delrin or polyurethane round bar and make them to measure yourself. Far cheaper than buying, especially from SMD 😆
Otherwise Google ‘delrin bushing’ or ‘polyurethane bushing’.
