Hi! I have identify the problem in my corsa 1.4 which is crankshaft, I just want to know that i refill the gap on crankshaft where the pulley enters, would the car give me the same perfomance as befor

I meant to say the key way gap where crankshaft gear fit is now expanded therefore when you set timing it doesn't come right because the crankshaft gear is lose then it loses power. So what I want to do is to refil the key way gap and resize it so that the crankshaft gear can fit without being lose.

Ah the woodruff key. It's either a square steel bar, or a piece like a slice of a solid cylinder of steel, then cut in half...like a half moon. There are a couple things you can do. Woodruff keys come in all sizes, instead of trying to fill a gap on the crankshaft, to do it right it would have to be welded then ground to size. Get a slightly bigger key that you can hammer in to oversize slot, the grind the other part, when you say 'crankshaft gear' you mean the harmonic balancer or just a pulley, whatever it has and grind the slot out ...maybe with a dremel or something just big enough to accept the bigger key. Make sense? Or am I way off on what is happening? Is it on the crank sticking of of engine or the pulley that the slot is too big?

thanks man we are on the same page but my worry is that "would the car give me the very same perfomance as before"? or I must just raise money for another engine

Yes. It will give you the same performance as before. I didn't answer your question, I got caught up in the fix. Geez, this is no way a new engine thing, completely repairable good as new. Either by my way or maybe there is a better way. But the worst case is the timing marks on the HB might be just a smidgen off. Tiny bit, as the HB might not be in the exact same place on the crank. But it can be timed and you are in business.

Thanks bro even though I come 2weeks later

Thanks once again I have refilled the crankshaft keyway and the engine is running smoothly. My challenge now is that after 3minutes the engine is running, the engine light pops out. I checked everything is connected. How to shut it off?

hey guys, am having a problem with the crankshaft pulley always having to go lose and failing to start, kindly help on how i can get the problem resolved permanently, i have replaced the pulley and sprocket so many times

Hi , i have the same problem, my crank has grew wider, which size of Sprocket did you used after you oversized the slot?

Hi I have serious problem guys help me , my Corsa c gamma 1.6 , I have changed my crankshaft pulley an now it's not pick uping the revs ,it overheating an the exhaust manifold becomes Red , the other mechanic told me change Thermostat,collant temperature sensor,idling sensor,pick up senso , crankshaft sensor,petrol pump an head set gasket I did change but it's still the same

Hie guys I have a problem with my corsa lite 1,4 2005 it looses power and miss fires and it really chaws the petrol I have change the ht lead cool pack I have some the top but still it looses power a times when I start the car the engine shakes hard and the car just over heats

Hi, if you changed your coil pack and it doesn't make difference, check spark plugs or either one of your injector is not okay, just double check before you waste money due to guess work

Mpho you gonna buy the same sprocket but u should take the crankshaft to engineering so that they can weld it and resize it with the sprocket that you have bought

Hi guys i have very same problem on 1.6 astra i welded the sprocket together with pulley so the car is misfiring. Can that be a cost???

Yes

Hi guys i have a problem with opel astra 1.6 estate i welded a pulley together withi crankshaft sprocket so the misfire. So can that welding be a cost of misfiring????

Moloi when you say you Refilled the crank does that mean you welded it and filed it down? i had this problem for a long time and I knew I would have to fix it and now I am forced to but I want to know what the best route is to go? Welding and filing or drilling and dowel?

i have i 1.4 i corso lite keyway needs to be repaired..... car has lost alot of power now speed very low and sound like a have a miss......... can i still drive the car ?

THE CRANK WHERE THEY KEYWAY GOES THERE IS A PLAY MAYBE 1CM OLAY CAR LOST POWER AND LIKE A MISS SOUND CAN ITS BE REPAIRED?
