I've done a few of these and the radiator isn't in the way, just the plastic covers and fan belt pulley on the crank have to come off.

yeah you guys are right
I had nissan on my mind and got confused with another post I was reading.
on the mazda I think the crank key points up at 12 oclock , this should line up the mark on the pulley with the pointer on the cover. as for the cam sprocket I think you position the A straight up if memory serves me right.
now that I think about it I pulled that other out of a manual I had. I'm sure it was the wrong serial number range most likly

The engine is a Mazda F2 and does use a timing belt

Swoop- no disrespect but this engine does have a timing belt- it has plastic covers over the belt- the chain equipped engines have the chain running in engine oil (at least the ones I've seen).

What engine am I dealing with? Just curious- I know older Yales used Mazda's- not sure what make/model this engine is

Thanks for all your help to both you guys

Hi Swoop,

I naturally thought with that ser number it would have been a Mazda engine with timing belt.

first off there is not a belt on this engine. It has a chain.
secondly you set the crank to 0 degrees (cylinder 1 on tdc) the timing mark and pointer/indicator on the cover/block should set you there.
thirdly get the cam turned so that #1 cylinder rockers are valves closed. There should be marks on the gears of both the crank gear and cam gear you can use.
fourthly the timing chain has 2 blue links that are specifically spaced and once you get the gears set in the right place those blue links should align with the marks on the gears.

thats it

easy peazy :o)

Hi BBforks Im afraid this post has come through four times this was due to some error message that Popped up on my screen, still I hope you have sufficient info to do job now,

Hi BBforks,

As I recall having removed Radiator, Cooling fan and bracket plus fan belt, and finally the crank shaft pulley held in place with cap head bolts one should be able to access plastic timing covers shielding the timing belt, remove the covers held in place with 6 mm bolts, 10 mm heads this should get you down to the timing belt, if the belt has broken remove the remains and check for any damage to pulleys and associated bearings and pulleys. Loosen of belt tensioner pulley.

Setting the cam shaft pulley to correct mark, on the circumference of cam pulley is a v mark may even look like A, on the cyl head face is a notch turn cam till A and notch line up,
Crank shaft gear look for key way directly above this should be timing mark, on crank case block you will be able to see notch about TDC area rotate crank shaft till gear mark and notch line up.
Fit new timing belt ensuring tensioner pulley goes to smooth side of belt adjust tensioner till belt is sufficiently tight, refit plastic covers and rebuild in reverse order, if you have not removed or altered distributor adjustment, then timing should be right and engine should start
