Hi All

 

My 300zx tt auto had an undignified ride home last week on the back of a recovery truck.

 

Upon investigation the conzult told me no signal from CAS.

 

Cleaned connection tried another CAS still no go.

 

Been out there today, stripped front down and found bolt holding tensioner pulley sheared off :(

 

Whats the chances of no damage???, should i be hopeful or is it time to say goodbye.

 

Before i move any pulleys is there any sequence/order i should move them in order to get them back in alignment?

 

Will try and get another tensioner and do a compression check keeping fingers crossed.

 

Was running really well until then.

Ok so belt come off then? most likely ok, saying that because the camshafts will very swiftly spin to the closed valve position due to the pressure from the camshaft lobs / valve springs, anyone who has done a cambelt swap and touched the pulley a smidge past the timing mark will have seen how quick they whip around.

 

In all of our time have never seen damage done from a broken or belt off situation as the above tends to save the day, however if the timing belt jumps but stays in place it can be more of a problem.

 

Best bet is to strip and sort out the broken pulley stud, refit the old belt in the correct position and with the minimum put back together start the engine, if starts and runs shut down and fit a new cambelt, nothing to loose, would be confident though.

Hi Jeff

 

Thanks for the reply.

 

Will try and get broken bolt out at the weekend.

 

One more question, i can align the cams back up but how can i tell whether the crank is on TDC, i can align the mark but not sure what stroke it would be on??

 

Have read lots of guides online including your one herehttp://www.300zx.co.uk/forums/showthread.php?135139-Align-timing-belt&highlight=cambelt but all of the ones I have seen are just replacement without the engine having moved .

 

Thanks
