how do u use the zetec camshaft timing locking kit?

[john_d]

zetec silvertop ive bought this but how do u use it? i know the bar goes into the cams, but how do u lock the crankshaft, im guessing u use 1 of the pins? TIA

next to the cps there is a 10mm headed bolt un do this and tern the engine over (buy hand) till the bar looks like it will nearly fit in the cams then screw to longer of the 2 thredded bolts (if you have to in your set) into this hold buy the cps then tern the crank over buy hand till it locks up you SHOULD then fined that the bar will then fit into the cams mite need to give it a tap tho

Exactly as well descibed, just to add, take plugs out lot easier to turn, then you can actually hear the crank web contact the pin that you insert, if bar is way off going in slots rotate another 180, as offset.

"Blacktop" upside down on a stand. Timing pin and blanking bolt.



and how the pin works inside.



I'd just add, having seen the results of ignoring this, is that both the cam plate and the crankshaft pin are only for alignment. DO NOT use them as locking devices for doing up or undoing any bolts.

Top info there,whats wrong with good old timing marks.

There are none on zetec

Timing marks aren't accurate enough for the tree huggers (emmissions standards strike again) ....... or simple enough for auto assembly perhaps.

My Zetec is in a single seater and timing marks are certainly not accurate enough. I use a dial gauge to find tdc and also to dial the cams in....

Did you check the Ford TDC timing pin against the dial gauge ? I don't see how you can 'dial in' cams using just a dial gauge. I use the conventional method of using one to measure a set valve lift (say 1mm) and a degree disc on the camshaft. Final adjustment on dyno using vernier pulleys.

I couldnt find where the locking bolt went into the block, so as I normally do used the dial gauge on top of the piston to find tdc, this gets rid of the dwell, then set the timing disc up with a pointer at the correct inlet full open position as dictated by the cam. Use the dial gauge to ensure that cam is on full lift, then fit pulleys. I would never use vernier pulleys, an unnessary expense. With standard Ford cams I would guess that the slots in the end of the cam can be assumed to be accurate, with aftermarket cams I wouldnt risk it.................

Well if your using a 'Silvertop' block you will have problems finding the timing pin location.

So your not logging either valve opening or closing when timing.
Vernier pulleys have always been an important aid to timing. Necessary back in the days of keyways (though they could be left out) to correct minor machining inaccuracy before CNC grinding. Nowadays they are necessary for optimising timing on a dyno. You can't tweak cams without an indication of movement.
With aftermarket cams the accuracy can usually be found to be good on the slots, its just the optimal setting might be 3degrees out. Found that to be very consistent on several dynoed engines.
Fords own cams are often damaged by owners who've used the alignment bar as a lock bar. And there is known tolerance problems which led to TSB issue.
