Hi all, following on from my previous thread about the snapped tappet.

I have now got two new exhaust valves, new stem seals, water pump seals and other bits, the valves are lapped in and head is back on. All seems to be in order.



Now I am trying to get the cams and crank timed up. I have taken off the ignition cover to reveal what I assume is the flywheel.



I couldn't find any definite marks on this to set it to TDC. I found it the old school way using a rod in the spark plug hole and marked it with red paint.



I read a few threads on this forum about timing these up and I also read the manual. I read bearbuster's thread here

http://husaberg.org/mechanical/4190-timing-marks-1996-fe-350-a.html

My cam seems to be the same as his and so with the cam lobes pointing down, the bolts are at three and nine o'clock.



Does this look correct? It doesn't look perfectly parallel to the head but its very very close.

Always very happy to get any advice and enjoy learning.

Thanks,
Joe

Open The other side to see two sprockets with marks for alinement. The side with The clutch.
 
Palle your motor is a 2nd generation and is different than Joef's. Joef's does not have the marks that align the balancer to the crank. His timing chain goes straight to the crank from the cam.

To find True TDC on the 1st gen motors I use the dead stop method to mark TDC. Ape makes the tool for this. Insert the piston stopper into the spark plug hole and turn the crank slowly until it stops the piston. Mark the flywheel and the case. Then spin the motor the other way around until it stops and mark just the case where the flywheel mark is. Now split the difference and mark between the two marks on the case. This is true TDC. I prefer to have the valves pointing up instead of down. You can then lay a straight edge across the lobes to help you judge when they are at the same height. The water pump impeller vanes will also help you sight when the cam is in the correct position as will the cam sprocket bolts as you have noted.

Thanks palle but husabutt is correct, we have different engines.

Thanks husabutt, I have used the dead stop method and found the exact TDC and I am happy that my cam sprocket bolts are parallel with the head.



I think I am ready to reassemble now and set the clearances...

ignition timing is a whole different game though. what I suggest is that you look for centre punch marks etc about 40mm to the right of that TDC mark you made. there WILL be a punch mark to the right OK?

when you get it running and have a nice idle, try to use a flashing timing light and time the engine using this. they are plain weird because you can't really work out WTF is going on but gradually you will get there. they want to lead by 33d BTDC at at maximum revs but they seem to do this from 2,000 revs and straight away as well.

like I say: weird!

FE570 low idle issue, outside of the usual suspects! (I think)
