Many of the fasteners on the Triumph bikes from the mid-90’s were plated steel, chrome or just a cheap plating. With stainless steel replacements very cheap to purchase I’ve listed below the bolts you can readily change.
As part of a running restoration on my T150 I’ve taken the opportunity to update the headstock bearings to the newer taper type. I’d taken the forks off for refitting with new stanchions (old ones were gouged and rusty) and the headlight, loom and front wheel too. All needed some attention.
I noticed when I took the old head bearings out that there was an extra ‘top hat’ cup that fitted into the dust cap under the top yoke, it’s obvious why it’s there to allow the top nut to pull down on it but strange that it’s not in the 74′ parts manual. The T140 and T160 models don’t have anything similar.
Equally strange was the fact that when locating the bottom taper bearing into the bottom yoke some of the taper faces are still visible and would be subject to grit/dirt/liquids from the road. No cover was supplied in the kit or listed in the parts manual again.
I spoke with Carl Rosners who supplied the kit and they’re going to look into it as it’s not ideal. As it’s Christmas not much is open so I’ve not been able to check with P&M Motorcycles or LP Williams however discussing this with the nice folks over at the TR03C club on Facebook it would appear this is normal! Still don’t like it though.
I’ve made up a think cover in stainless to reduce the opportunity for the race to get contaminated during use, very simple to make and I’ll install it until I know 100% I can’t change the bearings for ones that have a built-in cover.
