Timing Belt writeup

[Robert Bade]

I have this write-up too. Some pics don't load, but combined with Kneales link you have the deal layed out well. I just did mine in so it's pretty fresh in my mind, feel free to ask questions. Bob

Does anyone have a good link to a timing belt writeup?

I popped a belt.  It was my fault as a piece of hardware fell into the TB area 
during a valve cover gasket change.  Being old and deaf, I did not hear it - 
until I cranked the engine...  The hardware broke off a small piece of the 
protective flange around the crankshaft area and then presumably proceeded to 
wedge in between the crankshaft gear and break the belt.  So far it appears I'm 
lucky and no valves crashed.  I'll know more once the new belt is on and I 
gently turn the engine over a few dozen times by hand and then do a leak down 
test.

The specific question I have concerns the camshaft and crankshaft gears.  I have 
not yet taken them off.  Are they keyed with a woodruff or just tightened down 
onto a tapered shaft?  It's been so long since I did a change, I can't recall.  
Bentley shows a woodruff key for the camshaft on SOHC engines, although Scott 
Mackey's site says there may or may not be a camshaft gear key.  I cannot find 
anything about a keyed crankshaft gear.  Bentley just shows it neatly coming off 
with the vibration damper and the reverse of that for reassembly.

I have spare transportation so an answer is not urgently required, but it would 
be nice to have a good writeup as guidance for the remaining of the weekend.  I 
thought I had a writeup that I printed off from Cris Miller about a decade ago, 
but now I can't lay my hands on it.

As always, all help appreciated.
