Thread: Camshaft gear bolt. can't undo.

Try using a 6 sided impact socket, preferably on the end of an impact driver, if you're not keeping the timing gears jamb them either through a hole in the cam sprocket or jamb something in the gear and chain teeth. Or find a way of holding the crank still, give the breaker bar (not a ratchet) a sharp whack in the correct direction and it should break the seal, then use the ratchet, Regards frank.

The camshaft bolt (the one that holds the distributor drive gear and timing gear to the shaft) does not want to budge.

I not 100% sure what size the head is. my 19mm spanner and sockets feel a bit loose. 3/4 af is no better.

Anyone know the correct head size and a neat trick to getting the bolt to loosen?

Thanks,

Thanks Frank

I'll get a 6 sided socket.

Can anyone recommend the best size? Both 19mm an 3/4 af seem a bit loose.
