Viton clutch damper rubbers now completed approx 700 miles mostly local driving, Recent check revealed clutch basket freeplay still non exsistant and no vibration or noise noticed from clutch area. I would suggest vition as a possible solution.

Will feedback after 1500 miles.

I did think it a bit strange? Thought maybe there might be an issue but oil light goes out even under cranking and stays out until engine stops.
Now he knows engine's a runner I believe its full strip and refurb next..

CB350/400 / Missing oil pressure light?
« on: June 23, 2020, 09:59:26 AM »
A friend of mine has just brought a project bike (CB400 four) which is missing the oil pressure light.
Inst panel is complete with no extra holes but where top oil light should be is the Honda wings logo? Have told him to check if the oil pressure switch is fitted.
Have any members seen this before?

I have removed the rivets by center punch marking and drilling on a pillar drill right through with pilot drill (1.5mm) then opening out to 5mm Dia.
As per other posts on this site I have then tapped the six rivet holes to Std M6 thread, intending to use suitable bolts with threadlock upon reassembly with new cushion rubbers.
Still currently working on fabrication of cushion rubbers.

My original ones are black in colour, don't know the material Honda used or obtained in production.
As I have not been able able to find any "off the shelf" items suitable, I'm currently working on having a die and punch fly press tool made from gauge plate to be able to fabricate some new ones from "Viton" sheet. I will feed back on success when iv'e tried some.

Thanks for update Kevin,

Viton seemed to be the way to go so I have ordered a small sheet (200mm x 200mm) of correct thickness (10mm) and will have a go at fabricating one set to try. I,ll feed back on results.

Thanks all for input on this.

Mike

Thanks,
Sounds promising.

I have p.m. TTR400 regarding availability of cushion rubbers, he says -

Hi Mike,

Not at this time. the first batch i did could not hold up to the heat and hot oil. broke down after around 10.000 km's.

I have now sourced the correct material and will soon be doing a test etc.

Regards Kevin (ttr400)

Anybody have any thoughts on the material used to manufacture clutch basket cushion rubbers. The oil and temperatures involved could Viton be suitable if a little expensive?
