John L Posted May 30, 2023 Report Share Posted May 30, 2023 Looking at the Moss parts list, washer, 142388, says 'plain steel washer' should these not be hard washers as they are a thrust washers? Will be looking at doing the outer bushes there soon. Can anybody confirm please? John Quote Link to post Share on other sites
BlueTR3A-5EKT Posted May 30, 2023 Report Share Posted May 30, 2023 (edited) Yes hardened. ….and something tells me they were originally cyanide hardened, which is like case hardened. That was probably a spec on the original Triumph drawing. Best of luck with getting cyanide hardening done today! Edited May 30, 2023 by BlueTR3A-5EKT Quote Link to post Share on other sites
Z320 Posted May 30, 2023 Report Share Posted May 30, 2023 Yes, hardened, the one on the photo I damaged (brocken) to check. Some sell mild steel, checking them they will bend. Best you own old ones and use them further. Ciao, Marco Quote Link to post Share on other sites
RogerH Posted May 30, 2023 Report Share Posted May 30, 2023 You should be able to test the hard ones with a file. A decent hardened washer will cause the file to glide over the surface. Mild steel will shed filings. Roger Quote Link to post Share on other sites

I smashed it with a hammer only for this photo and a dramatic demonstration on another forum (years ago). Sorry me if I caused any irritation! Quote Link to post Share on other sites
RogerH Posted May 31, 2023 Report Share Posted May 31, 2023 Hi Marco, I spent a life time doing NON- Destructive testing. It was a joy to see the results of your Destructive testing. Roger Quote Link to post Share on other sites
Z320 Posted May 31, 2023 Report Share Posted May 31, 2023 (edited) The problem with this washers, dust covers, POM bushes, paint on the wishbones and spacers is the needed CORRECT length of the spacers. All locked tight together with the castled nut (this is why the washers have to be hardened) is a solid metal unit with minimum enough space between the washers to let the the POM bush slide on the steel distancers.
