My first ever cambelt change...
A few important additional points to note:
When I fitted the new cambelt I set the crank at 50 degrees ATDC - that's the all important dot or raised point to the right. But I set the engine at TDC prior to that to ensure the correct kicking off point... The TDC photo is after turning the newly fitted belt two rotations: it all fits and matches the marks if you follow the instructions - if it doesn't then start again and get a sanity check from the forum or other source. I mention the 50 degs mark it in the early parts and in Photo No 5 but forgot this at the write-up at setting up the timing = there is a lack of detail. I have attempted to edit this...
Do follow the official instructions.
If you are unsure about anything do ask the forum, mechanic etc.
