A bit premature to say the least but had a brain fart and hot start type nonsense going on.
If there is a lot of blue/green dust over your fan shroud, then worry, your lining is toast and you will want to get it cleaned off so it doesn't get into the carb.
So got the remains of the liner out with a mixture of acetone and careful scraping with a stanley blade. Finally sanded carefully with a dremel making sure that the scored pattern is not erased because it helps to key in the epoxy.
So I have the new liner, long 24 hr cure Araldite, some thin acetate sheet from the stationers and of course a new liner.
The liner looks to be pressed out on a machine, there is a slightly raised border all the way around, doesn't look significant but can spoil your day if you don't take accounts of it, more later.
1. Cut the liner to size carefully cutting half a mm off when close, had this tight and bang on but dont try the so called "B" bend to get the ends together, mine cracked but didnt worry cos its all glued on.
2. Warmed up the epoxy in warm water so it mixes and flows easier, it can be difficult when cold.
3. Prepared the clutch and put 2 large bolts through so I can get it off again (Top tip), also cut some acetate strips so that there is just a small gap when put around the clutch.
4. Spread a thin even layer of epoxy around the inside of the clutch bell, warmed it up slightly with a heat gun to help the epoxy spread.
5. Carefully put the new liner in with the raised border against the metal, then inserted 1 acetate sheet and pushed the clutch inside it, went in easily, so thought what the hell and put in another acetate sheet, this time quite a bit of force was required, but now enough pressure was there to flatten that slightly raised part against the metal. I knew this was good because a gap of about 1mm appeared on the ends despite being careful to get it exact! I used Acetone on a cloth to easily wipe away any excess epoxy, a small amount seeped out which is good.
6. Next day, I cut off the exposed acetate, good job I put the bolts in because I need a firm pull with the bolts held in a vice. It did slip out nice and cleanly though.
Looking good now, assembled, there were one or 2 high spots that disappeared by just using the starter for a few secs, like new again.
