Cam Chain n Tensioner
- The off subject post about the cam chain reminded me of a post John
Fitzwater from Thunderbike.co.nz had sent re: another off subject post
about Gearbox problems.
>>Just saw this post and thought I'd throw my $0.02 in... Might helpsomeone.
While the T3 engine is bloody strong, and capable of big miles, the cam
chain tensioner is not - it's only reliably good for about 30,000km or
18000 miles in our experience. I've seen more T3 engines damaged by broken
cam chain tensioner blades than by any other cause - the tensioner fails,
the cam chain runs loose, flaps against the aluminium block adding
aluminium to the oil - a perfect grinding paste - it totals the crank,
pistons, oil pump if not picked up - and it's sometimes difficult to pickup
over the normal timing gear clatter. We ran a lot of T3s and T4s in our
motorcycle tour fleet for years, and also have the experience of being a
Triumph dealer since '94. We always advise clients to replace the tensioner
blades at the mileage I've given above.
Hope this helps...
Best to all,
I have not experience dealing with checking the cam chain or the tensioner.
In fact, I'm guilty of not checking it at all and at 115k miles I should
figure out how to do this. Anyway, hope the Fitzwater insight is helpful.
