Glanzaa-V Posted February 28, 2011 Share Posted February 28, 2011 Hey all,Just about to go tighten my c/h head down, Just wanted to no, Do i have to rotate my bottom pulley round so that the pistons are top dead center? Another words rotate the bottom pulley so that the grooves on the pulley match up with the triangle on the oil pump casing...?ORDo i leave the pulley and pistons were they are from when i took the old head off? I turned the bottom pulley to get the cams timed up before i took the head off? So therfore it should be okay to put the head back on and the cams back in the same way i took them out?Hope you can all understand this ha Thanks in advance..Phil Quote Link to post Share on other sites
Whitegv Posted February 28, 2011 Share Posted February 28, 2011 surely your engine would be at tdc when your cams were timed, if you put the engine so cyl1 & cly 4 are at tdc (the mark is on the crack pulley) then line your cams with the dots it will be fine,i did mine like this and it runs bob on, obv you have to time it all together once you get your cam pulley on for the cam belt Quote Link to post Share on other sites

Does the 4e mark have to align up to something? Well the crank pulley at the moment is at tdc?P Quote Link to post Share on other sites
Sparky Posted February 28, 2011 Share Posted February 28, 2011 Cams in lined up, crank pulley on with cylinder 1 and 4 at tdc then cam pulley on the 4e slot as said.Basically when you take the cam pulley off there are two slots, 4e and 5e, just put it so the slot sits on the 4e mark, you'll see what I mean Quote Link to post Share on other sites
Glanzaa-V Posted February 28, 2011 Author Share Posted February 28, 2011 and when you come to put the belt on that the bottom crank mark is alighned to its mark on the oil pump housing... Sorted everything else thanks guys.. ^ But this is what im struggling with atm ^ ^ ^ Any help or pics ? Please & thankyou Phil Quote Link to post Share on other sites
Whitegv Posted February 28, 2011 Share Posted February 28, 2011 the mark is really small, is the engine out of the car?just take your time and have a look around the bottom pulley, on the engine side rim of the pulley there is a small mark, if its hard to see, when you find it put a small bit of tip ex or something on it so it can be seen easier. line that bit up with the mark on the pump housing you should feel where tdc is because the crank will go light then tight again Quote Link to post Share on other sites
Sparky Posted February 28, 2011 Share Posted February 28, 2011 A good tip to find TDC when the head is fitted is to remove the plug from cylinder 1 and put an extension bar down there and rest it on top of the piston, then turn it over until the extension bar reaches its highest point Quote Link to post Share on other sites
