Hi guys.

I own a 1200 delux and a skyline,
My problem is with the SKyline this time.

Well, mines is the the Skyline GTX, only assembled with the L28 motor, exactly like the Z cars, here in South Africa.
None of the guys on the Skyline sites can assist due to this.

Well you see, I have had the crank pulley come of twice thus far.
This time time it has come off, and half the bolt broke into the crank. This is no problem though.

My problem is that how can I stop the pulley coming off this often.
I beleive this is a common problem with the L28e motors.

I have previously, put on lot of Loctight on, purchased key ways from Nissan, however, same problem.
Do I probably have to have the pulley balanced before putting it on this time?
Any suggestions welcome.
