Location for cylinder head buckets

8 posts in this topic

Hi, 

I'm not sure if this is the right name, but after the location of the buckets. I've managed to drop 7 out because I was an idiot. 

I've bought a gauge but can't fit it for the main tips. 

The buckets all have the measurements inside them but not sure which valves? They go onto. 

Any help would be great. 

 

I have attached a photo of what I mean

I think thats the shim inside the buckets, you'd have to work out what size shim you need for each valve clearance.

I thought it wasn't going to be so straight forward haha. I've bought a measure tool and it's the wrong thing. 

I've read that I put the camshaft on (no point ***** down) and then measure with a feeler gauge to the correct one? That right? 

Shim is right - I'm not good when it comes to this stuff.

Okay, I have done some searching and think I can ask in a better manner now.

 

I am after the tolerance for the gap between the camshaft and valve tapets. found this, but unsure if it's correct and if they are wrong. Anyone know where I can find out?

 

Tolerance is 0.17MM to 0.23MM (Intake) and 0.31MM 0.37MM (Exhaust)

 

It's for a 2011 Ford Fiesta Zetec S.

read the thickness from the underside of tappet
The number on the valve tappet indicates the thickness of the bottom of the tappet. However, the number only indicates the digits after the decimal point (example: 725 = 2.725).
Calculate the valve tappet thickness required (thickness of the currently installed tappet + the measured valve clearance - the required valve clearance).

Thanks for that! 
"(thickness of the currently installed tappet + the measured valve clearance - the required valve clearance)."
Will that still work even with the tappet out? as I am missing 7 tappets (I've got them just need to work where they go). 

if I put the camshaft on (unscrewed) I get two different readings from the same tappet 0.18mm and 0.20mm (intake) - am I best ***** them down and doing the missing ones that way?

Could someone please confirm I have this right? 

I've currently finished doing the intake, I have them all set to 0.18mm this is when the lobe on the camshaft is facing upwards and not touching the bucket. 

Is this right? 0.18mm was the distance for the ones already in, so the ones that dropped out I have set to 0.18mm
