OK in deep crap ,or not in deep crap .crankshaft pulley.

no mail is running on friday (happy New Years!), it would have to be monday. Fed Ex might take it saturday, but USPS would be cheaper.

I'll take the free one how much to send it to Costa Mesa Or how much will it weigh etc
A guy at a local shop said cannot weld it's cast .
He also said it sounds (by description ) like the starter isn't engaging. I used some degreaser and cleaned the he'll out of it and threw on some loctite heavy duty 4000tensile strength epoxy on it we shall see tomorrow if I'll be cruising or bruising my last nerve cleaning that shit off

[Petros]

cast iron can be welded, but needs special process. Mostly it has to be heated first, and than annealed after welding, which means the bond between the rubber dampener band and hub will be toast, so not suitable for the dampener. But even if possible, welding up and than machining down would likely cost over $100, perhaps as much as $200.

The epoxy process, with a new key, plus correct torque up on the bolt, it should hold up for a while. As long as all the voids are completely filled, should be a good interim repair. Wait for it to break down before you install the new one, that way it will not be as much to trouble to pull apart.

I got a baaaaaaaaad feeling guys.
If that stupid little strip of stuff on the inside of outer radius of this God forsaken piece of the cursed puzzle that is the tercel ,happens to go bad , does it ...........slip.......thus spinning the outer ring and leaving the crank shaft unturned ?

[Petros]

no, the crank is what drives the front pulley and cog belt, that drives the cam shaft. If the key fails completely, it will allow the valve timing to go out of sync and the engine stops running. it would be bad if the valves could strike the pistons, but in the 3a engine there is enough clearance so all the valves could be full open and the crank shaft spins without striking the pistons.

The worst that will happen is it will first run badly, than not run at all. So you have replace the parts necessary to keep the valve timing in sync with the crank.

If the rubber strip goes bad, the engine will be out of balance a little, that is all.

[Mark]

I'm still confused as to what exactly is happening. Is the lower timing belt pulley on the crankshaft slipping? Even with a worn keyway, I can't see the pulley completely slipping with a new key. Also you say the engine doesn't turn over? The starter should be turning the crankshaft and then if the crankshaft pulley is slipping, the timing belt isn't rotating? Do you have a picture of the problem?

[xirdneh]

Are not the crank pulley and time gear (pulley) on separate keys?

[Mark]

Yeah, if the crankshaft pulley was slipping, the car should still start and run (for awhile anyways). the alternator and water pump won't be turning though.

[gnarnold]

That's just the thing guys the wheel ,bolt and everything else is turning .starter was under warranty so I exchanged it ..still the same noise .I'm thinking it could be the battery maybe it's not charged enough to crank it but if it spins it should turn over right

Same key.

[gnarnold]

Well I figured out I bumped the cam timing gear when installing the new belt .put it back to what the book said .it started and runs .like cap though loss of power .stalls at stop light sounds loud .found a hole the size of a dime in the rear exhaust by the muffler .

Yes, it will run, and eventually the crankshaft will fail. It is not so much about balance, but about dampening the harmonics of the crank shaft. when each piston fires it winds up the crank slightly, like a torsional spring, and at certain rpms each of these slight unwinding of the crank can couple when harmonics match the rpm, the forces on it will multiply and can get very high at certain rpms. It will cause a crank failure, I have seen it before with a failed dampener. the dampener serves to dampen these harmonics and greatly limit peak forces on the crank.

I have no idea what you are talking about. what spins? crank? what does "turn over" mean? I hope your engine does not turn over, it means either the engine mounts failed and it ripped it way out or the whole car is upside down (hard on the paint job). This term "turn over" means different things to different people and it is not used consistently.

Do you mean the engine is cranking but it will not run on it own?

It sounds like you got it running on the last post, but running poorly. Check the valve timing is correct (from marks on front pulley TDC and timing hole lines up with mark on head at cam sprocket), make sure the spark timing is correct (requires timing light, rent one if you do not have access to one), the spark plug firing order is correct, and you have no vacuum leaks.

[gnarnold]

That's what I figured
