ukcruisin 0 Posted December 9, 2008 Hi all....need some advice if poss....(Have searched at length but can't pinpoint the answer) Ive just replaced the head gasket and water pump on my 16V 2L (9A) Corrado, Its obviously getting a new timing belt and tensioner whilst in bits but when checking the freeness of rotation on the intermediate shaft pulley it feels ok most of the time but there are moments when it feels like its 'grabbing' and a little stiff. I have taken this pulley off and undone the two bolts and removed the oil seal and housing hoping I would find a bearing on the end but alas nothing. So heres my questions..... 1. How freely should this shaft turn or will it always feel slightly tight 2. Are these prone to bearing failure? Is this an engine strip down job Crank out etc? 3. Does this shaft drive the oil pump? I assume it does Any help much appreciated!! :D Cheers guys Quote Share this post Link to post Share on other sites
Supercharged 2 Posted December 10, 2008 Yep on the 16V it just drives the oil pump - so timing of this pulley does not matter Quote Share this post Link to post Share on other sites
ukcruisin 0 Posted December 10, 2008 Thanks for the reply but I knew that it wasnt related to any timing issues I just wondered if a bearing failure was common? And if a bearing change involved having the crank out? Does anyone have of an exploded diagram of the internals of a 9A engine? :? Thanks again Quote Share this post Link to post Share on other sites
keithabc216v 0 Posted December 10, 2008 it should turn freely you dont have to touch crank but you have to drop engine or take engine up to get the shaft out just had to do this as bearing had failed on mine Quote Share this post Link to post Share on other sites
ukcruisin 0 Posted December 11, 2008 Thats great info thanks Keith. So if I have enough clearance, I assume I cant just pull on that shaft and expect it to slide out because it would slide out of its own accord once the engine was running. So is there something I have to undo to slide that shaft out? (Like remove the oil pump so the gears dont engage it?) Any ideas? Thanx Andy Quote Share this post Link to post Share on other sites
keithabc216v 0 Posted December 11, 2008 ITS HELD ONLY AT THE FRONT IT WILL DISENGAGE FROM THE PUMP OK YOUVE GOT TO TAKE THE CAM BELT OFF TAKE THE SPROKET OF 2 BOLTS SEAL FLANGE AND OIL SEAL THEN IT WILL SLIDE OUT BEARING IS ABOUT £7 MINE WAS SO KNAKERED IT CAME OUT NO PROBLEM HERES HOPEING THE ONLY THING THAT I THINK CAUSED THIS IS WRONG TENSION ON CAMBELT ABOUT 20K MILES AGO GOOD LUCK just a thought as the only thing the shaft drives is the oil pump might be the pump itself worn ?
