Hi All.
Just about to change the cambelt on my daughters 1.4 Furio (8v). Got a Haynes manual, but the manual and the current timing hole settings on the cam sprocket seem to conflict.
Tried checking through the forums and couldn't find the answer - or i am simply being Numpty.
Problem is that according to the manual, the cam sprocket hole and crank hole should line up when "No 1 cylinder is at TDC on its compression stroke".
From what seems to be happening with the sprocket hole and followers, I'm not sure what position the followers would be when in that position. I think they should both be loose (longest cycle between inlet and exhaust opening), but when the cam sprocket lines up, the rockers are between the inlet closing and the exhaust opening on the cylinder closest to the clutch, which I think is Bottom dead centre (BDC). The opposite end cylinder 4 (at the cam end) has loose tappets, which I think is the correct position for the compression stroke. (NOte I hadn't found the 'correct'; flywheel hole at that time).
Information here seems to conflict as to which is No1 and No 4 cylinder. Haynes manual says it is at the flywheel end. Some threads here have suggested both. Anyone know for absolutely sure?
Finally found the pesky flywheel locking hole. Now, locking the flywheel has the sprocket at 7 o'clock directly opposite the 2 o'clock position and the tappets loose on the cylinder closest to the flywheel. Seems like this is TDC for the cylinder closest to the flywheel but the cam sprocket doesn't line up. The fact that it is 180 degress out makes me wonder if it possible for someone to put the sprocket on back to front?
For info - locating the hole for the flywheel lock seems like an impossibility. On this 2001 Furio, the Oil filter is in the way, severely restricting access. I thought I had found it, but I was poking around in the Timing access hole - the correct hole is much smaller and tucked right into the corner of the block (thanks to some of the excellent threads on here). Try an Allen Key on a piece of tube to get it down there....
Hopefully someone can come to my rescue and stop me chucking spanners around and tearing hair out. It really must be simple, no????
