Default 1.8 Timing belt change.

Hi Team-
Weather here is just gorgeous, so taking advantage to service my new ZT. I have Oil, filters, and plugs. It will also involve my first ever timing belt change so I'm trying to be fully prepared.
Applied PlusGas to all bolts on offside engine mount earlier.
I have:
Timing and auxiliary belts.
Tensioner with new bolt.
Water pump.

Collecting 22mm socket and coolant in the morning, then getting to it with fresh pants and Brave Pill on standby.

What have I forgotten??
Gasket seal on water pump?

Got trolley jack for engine, decent set of Hex sockets, long bar for crank pulley bolt. What might I be missing??? Can't run to motor factor if I get stuck- they're doing 'phone or email orders and delivery.
Any tips gratefully received.

A locking tool for the camshaft pulleys!

If you’re using the bar rather than an impact gun on the crank pulley, you’ll need a means of locking the flywheel (a stout screwdriver should do it) and an assistance to hold this in place.

Thanks Gents.
Starter motor to undo the pulley bolt?
That's a bit fierce, but guessing you've never had a breaker bar fly off over the fence and brain the neighbours dog.
Now you mention the cam locking tool I think I have one- bought it a ages back for the TF then chickened out. Hope I can find it. Much more room to work on the ZT.
If the sun's out tomorrow we'll have a go.
Cheers

Take note of the tensioner position, the centre is a teardrop or egg shape, you can adjust both ways but the correct way is the more pointed shape downwards

For everyone who replied, many thanks.
The crank pulley which I thought would be a real problem popped right off.
Plugs out, fuel pump fuse removed (numer 28 under the glove box) 22mm impact socket and breaker bar wedged in place.
2 second crank of the starter motor and all done with no drama.
In fact, the rusty screws meant that getting the wheel arch liner off was more trouble.
Got as far as fitting the new water pump before the light started to fail. Should get it back together tomorrow morning.
Cheers All.

Time to fit the new belt, and I'm finding that it won't sit over the teeth of both cam gears at the same time.
Locking tool went in place before the old belt came off, and hasn't been removed, but it looks as if the cams have shifted very slightly relative to each other? Also feels much too loose on the driven side (towards front of the).
I haven't done this before, but it looks as if I need to removed the locking tool and tweak the cam gear to both tighten the driven side and let the belt sit home properly. Can that be possible??
Any tips gratefully received.

Hi All.
I've been sitting looking at my car for an hour, and I'll try answering my own question.
I think my timing was very slightly wrong to begin with- the marks didn't want to line up properly.
I think I start by tweaking the crank. It's very slightly too far clockwise, so adjust until the oil pump rib sits dead on between the two dots on the crank.
Then I have to set the cams. I suspect they should only rotate clockwise?
If so: one of them will need a tiny tweak, the other almost a full rotation. Once the timing marks on the gears are exactly right I lock them and fit the belt.

So for those in the know,
1. Clockwise only for the cams?
2 Ok to move them independently?
3 Ok to turn them by putting a socket on the bolt holding the gear in place?

Or, am I making this too complicated?
Cheers

If I understand what you mean, then - - - - -
Oh I think I understand. You think one of the sprockets was a tooth out of line?

Do you not have a Haynes manual?
