Over here, I'd probably check McMaster Carr first. But Flea Bay would probably be my go-to otherwise.
So, I'm gonna SWAG that it's an M8 bolt (which requires a 8.2mm bore size for clearance), that the head size should be 25mm, and that the internal diameter of the rubber bush is 15mm or thereabouts. Which seems reasonable. Countersunk finish washers (may be available in either flat or cone styles): Stainless: M3M4M5M6M8M10 Stainless Steel Screws Cup Washers Countersunk Finishing Washer Countersunk Washers Finishing Washer Fasteners for Screw Parts Washers Alloy: ZSPEC M8 Fender-Finish Washers for M8 FHSC Flat-Head Fasteners, Billet, 10-Pack M4/M5-M8 Aluminium Countersunk Washers DIY Washers For Countersunk Head Screws Most of the alloy washers seem to be 6061, and may be available in all colors on anodized.

Unthreaded Alloy Standoff Spacers for M8 bolts: M4 M5 M6 M8 M10 6082 ALUMINIUM STAND OFF SPACERS COLLAR BUSHES BONNET RAISERS
^^ UK stockist, 1, 2, 5 or 10 pack options, diameters 12/16/20mm, lengths 5-50mm in increments of 5mm. Stainless standoff spacers for M8 bolts: Stainless Steel Spacer - Standoff Collar Stand Off Spacers | M5 | M6 | M8 | M10 ^^ Uk Stockist, 1, 2, 5 or 10 pack options, diameters 12.7/16/20mm, lengths 1/4, 3/8, 1/2, 3/4 & 1" (LOL)... Obviously, you could stack multiple standoff spacers to achieve the exact length(s) you want. Or someone with access to a lathe could spin you up 8 spacers in pretty short order, I'd think. At which point I got kind of bored. There's literally 100s of suppliers of standard items like these... Moreover, once you start poking around listings like these, Flea Bay will suggest multiple similar ones too. Last edited by spuggy; 24-06-2024 at 11:03 PM.. Reason: Add stainless standoff option |

Thanks for all the info Spuggy, now I know what to search for there's loads as you say. The McMaster site looks great but I'm sure I can find a UK equivalent. My next step is to dismantle what I have and get some precise measurements. Thanks for all your help.

As Mr Gazza observes, the factory supported the rubber bushing on both sides; there's a washer behind the silentbloc (apart from that one place on the M900 parts diagram that I think is a mistake), and the head of the shouldered bolt contains it at the front, so the bush is all sandwiched in place and constrained. The back end (between the hanger and whatever it fits to, frame or crankcase/prop stand bracket, whatever) - is just spacer dimension & exposed thread. What I really like about Mr Gazza's approach, is that the end result looks very tidy - it could have come from the factory. I did wonder - as he mused earlier - if you could utilize a factory part - like the washer the factory used on the oil cooler fixings. Which may be 84110011C, which some describe as "fairing mounting cap" - and might be available in silver or gold (seen both). This would likely limit the availabilty of M8 bolts though, as that washer wants to be used with a low profile socket cap head, which don't look to be as readily available in longer lengths (over 60mm). That may even be long enough... Measuring it all up and figuring out what's needed would seem to be key... Last edited by spuggy; 25-06-2024 at 07:38 PM.. |
