Field Notes: LS400 Timing belt & Ancillaries


Description

Lexus LS400 Year 2000 Field Notes on Cambelt, waterpump and pulley replacement

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.

Just a tip on a handy tool I made to help get the crank bolt off and on easy on the LS400. 

Bought a very large 46 mm open end wrench ( bought for 10£ ) and drilled two 8 mm holes to fit the 8 mm holes in the damper . Fitted two M8 screws  + 2 nuts. Screw thread sticking out ca 25 mm .
