Engine Locked Up After Clutch And Flywheel Change

[Stringer87]

Hi all,

 

I have just replaced the clutch and rear crankshaft seal on my 2003 GV have got the car completely built back up and the engine has seized solid it won’t even turn with a bar on the crack pully..... I fear I may have done up the flywheel bolts to tight I done them to 100nm

 

Can anyone confirm if this is far to tight and have the correct torque spec for it, or simply any other suggestions of things to try before I take the box back off.

 

Many thanks in advance

Possibly worth mentioning that it’s a 2.5 CRD engine ??

Are you sure its not in gear. Jack up a back wheel and try turning it.

Slightly confused ?‍♂️ one thing I never mentioned it’s a manual gearbox.... how will jacking the back up help? As it’s a FWD

Thankyou for your response

Hic burp right enough have you tried a front wheel then. Jack up, turn wheel, in neutral it should be free. Them turn with clutch pressed and in gear, if it turns clutch plate is free and not the problem.

Would doing this also prove that the flywheel is not to tight and binding? i.e with car in gear and the clutch down does the flywheel turn as well when the wheel is turned?

Many thanks for your responses

I am pretty good at mechanical work but have never come across this before so a little stumped on the diagnosis side of it, short of taking it all apart and starting again

Hmm no it wouldn't, because if the engine was running the flywheel would be turning and separated from the gearbox and wheels by the clutch being pressed down.

You turn the wheel and if its in gear, motion goes right through gearbox and out clutch end by help of the first motion shaft. The first motion shaft is splined and has clutch plate which is also splined sliding on it. Clutch plate is clamped between two facing rings inside Clutch except when clutch pedal is depressed. Clutch housing is attached to flywheel, flywheel to crankshaft. 

Picture might help but this should do.

Thanks for your responses.

I am going to brave the cold and attack it this weekend even if it means a full strip down again :-S

Just incase a full strip is required would anyone know the correct torque settings for the flywheel?

I have got this emotional feeling that I over torqued it and it’s bound solid on the crank case.

But I will give it a good go to prove otherwise

Thanks in advance

Quick update on this.......

Stripped all apart today and the problem lies with the new crankshaft oil seal that sits behind the flywheel..... it would appear that the metal used to make it is to thin, about 1mm. Thusly meaning the flywheel bolted back to tight against the crankcase. I bought it off eBay for 35 quid so I would say its a bad case of buy cheap buy twice.

Going to speak to Chrysler on Monday and see what a genuine part will set me back.

Will keep you posted
