1990 Mazda MX-6 2.2 Timing belt issue.?

Question

Hello,
I have a 1990 Mazada MX-6 2.2 SOHC with a man trans. Recently the time belt went ( at a low speed under 20mph ) I recently replaced the belt. I am a fairly decent mech when it comes to chev ford ect.. but mazada's have always intimidated me. I have the Cam at the #1 position with the arrow on the timing mark imprinted into the valve cover body. I have the Crank Timing mark 3 little marks past the " T " symbol ( i am guessing TDC ) and it is on the compression stroke near as i can figure. Tightend the tensioner and check for slack in belt. The motor started but died almost immediatly. i adjusted the distributer a few degree's either way and it would start rev somewhat high ( 2k maybe 2500 ) then fall and die. I know Nissan's can be touchy what am i doing wrong? All input is appreciated.

Well as far as going from a Mazda to a Nissan, i was just stating that i know from previous exp that Nissan's timing can be really really touchy and i was just hoping this one isn't as touchy. =-) I hade the cam at the correct mark. though i didn't check the distributer. ( will check that now though ), the bottom gear is well a little of a mystery. I know there is a timing gear with a key slot and a baffle that goes between the gear and the outter pulley. I really didn't see any other markings on the lower timing gear when I went to replace the belt. I looked up interference motors from your repspone, I do have a belt not a chain though i am not sure if it qualify's as a " rubber belt " but i bet it might since it is of a Belt variety. I thankyou for your response and will re-check what i have done already with this car. thankyou =-)

Answer 1

There is a notch in the back side of the crank pulley that should line up with an arrow on the front side of the block. This will indicate that you are on TDC. The cam pulley also had a mark that should line up with an arrow on the valve cover. When you put the belt on, make sure that these marks are still in alignment when the belt is tensioned. Sometimes the cam moves slightly and must be reset. It is best to turn the engine over once to verify that the marks are still in alignment before putting it all back together. There is no chance of the valves hitting the pistons on this motor.

Answer 2

How did you get from putting a timing belt on a mazda to starting a nissan? Pull #1 plug and make sure your piston is at TDC and that your cam is in the firing postion (both lobes up) and you timing marks are aligned....be sure the distributor is pointing towards #1 and all should be well...unless you have an interference motor, then it will have tagged a valve no matter how slow you were going...good luck

Answer 4

approximately each and every 60k miles that is cautioned to steer away from important problems....right this is what my mechanic chum only pronounced to this question (pronounced as him, works on Mazda's in basic terms) "mutually as the engine is non-interference he has seen engines destroyed while the belt broke at extreme speeds. $3 hundred vs a minimum of $3000, which do you %."
