Sorry, probably leading you astray there I'm about to tackle the cambelt on my Mk2 Golf so that procedure is at the forefront of my mind.

A mystery has now arisen.

 

I tried rotating the crank to find TDC (with a long slim length of wood through No.1 spark plug hole) and, although the crank turns fine in an anti-clockwise direction, it will only turn a few degrees clockwise before coming to a dead stop and refusing to budge further.

 

I've rotated it 5 or 6 revolutions anticlockwise and it turns fine.

 

There are no locking pins in place and it turned just fine before I removed the crank pulley bolt.

 

If the timing has slipped, I should able to set it right when I adjust the camshafts, shouldn't I?

 

But why will it turn anti-clockwise ad infinitum, but locks up after a short rotation clockwise?

the story gets stranger....still cant get my head round bending the locking pin but hey ho..now sorted

only reason i can think of for crank not turning is its hitting a valve, but why it doesnt do this going other way is beyond me..

try turning the cams back a 1/4 turn then try turning crank...be very careful as its possible to bend a valve when turning by hand so dont force anything.

Yes, I'll turn the cams when I get the cylinder head cover off.

 

I can't do this job in the sequence suggested by the Ford Workshop manual as the engine mounting bracket overlaps the cylinder head cover by a couple of millimeters, so I can't remove the cover before the bracket

 

For days now, I've been puzzling over how to access the bolts holding the power steering pulley. If I had arms like an octopus and hands like a newborn baby, I'd have done it it in five minute flat.

 

And I also have to get the crank pulley off now I've removed the bolt.

off top of my head...i would normally make undoing the crank bolt/removing the mount the first jobs..so

car on stands, support engine with a jack, ideally on timing belt end of engine. remove engine mount, this will allow you to raise and lower engine via jack to gain more access to pulleys and cover bolts..

can either give crank pulley gentle taps to break the seal, or lever it off with couple of screwdivers behind pulley..dont use chisel/screwdrivers/hammers on the belt ribs of pulley to drift it off, as they will get damaged easily.

when cam covers are off, should see a hex built into camshafts, use them to lock the cam when undoing/tightening cam pulleys, dont rely on the cam locking tool for this though should be ok to leave the tool in place..just let the spanner on the hax take the pressure

i thought the pas pulleys were pressed on not bolted, from memory you only needed to move the pump a little on models with air con...could be wrong though.

one other tip...set the crank at tdc, then turn approx 90deg, that way, pistons are halfway up their stroke and pose no danger whilst you set the cam timing and loosen the pulleys..once thats done, then set the crank at tdc and fit the belt

Thanks for all advice.

 

Actually, I didn't mean the PAS pulley: I meant the pump. The stress of this job has affected my typing (and thinking)

 

The PAS pump bolts are difficult to see - I can see only two and there are supposed to be three - and they're difficult to get at too.

 

I shall persevere .

For days and days I've been trying without success to find the three nuts to loosen the power steering pulley.

 

I've found two quite easily but the third is nowhere to seen, felt or in any other way detected.

 

Below is the diagram from the Ford workshop manual:

 

Firstly, perhaps a silly question, are we looking from on top or underneath?

 

I ask because it doesn't look very much like the real-life view from either direction.

 

I've searched with my eyes, and with my hands in places my eyes can't see.

 

But can I find that third bolt?

 

Can I (heck).

firstly, i take it your car has air conditioning and the PAS pump is roughly top and rear of engine as you look from front of car.
that being the case, you are looking at the picture as if you were sitting in the drivers seat, so to speak...so 2 of the bolts have to be removed from alternator belt side of engine, third bolt is screwed in from reverse side of those, ...imagine a wheel with 3 nuts...two of which facing outwards, 3rd is facing in and accessed from inside of wheel...think that makes sense

if PAS is under the car at the front, as viewed from front..then you dont have air con and dont need to touch PAS pump to do the belt

Yes, it has air conditioning..

 

As I stand at the driver's wing looking down at the engine bay, the power steering pump is facing me (right above the aux belt tensioner pulley) and it has two bolts running (away from me)  through a mounting plate. A nut screws onto each bolt on the opposite side of the mounting plate.

 

So far so good,

 

However, I'm totally mystified by your description of the other nut's location.

 

Please try again, cos I'll be over the moon if I can move this p/s pump.

 

Thanks.

apologies..doing this from memory and long time since i did 1.25 with AC

looking at the pic, i can see now that the nuts are on reverse side, thought they were just studded bolts.
so going by that pic, the third is hidden same side but tucked closer to engine block, you might be able to view it easier from under car

you may also find the nut or bolt is now reverse so unscrewed towards you as you stand at the wing

In fact, the p/s pump is held on by two bolts (not nuts as I said above, confused cos the Ford Workshop manual says 'nuts').

 

Here's a pic taken from the driver's wing, looking downwards.

 

The two bolts, one vertically above the other, are arrowed in red.

 

Where's the third bolt in relation to these two?

im convinced your undoing the wrong bolts there.

if you compare your pic to the ford one, you can see the bolts you have undone are not the ones arrowed.

in your pic, you can see one of the studs you want directly above the bolt you have undone in the foreground..the bolts you want are verticle fitted, not horizontal
