First time for me doing the timing belt on my 1991 164L.. I have done them before on my GTV6 and 3.0 Milano. What used to be the "new tensioner" spring made in Canada done at 70K when mechanical removed. Service by BMW guys. When I first looked at the tensioner pointer was high by 5mm. Removed the tensioner and checked the spring. Appears to be working. Now that I have reinstalled it I can't get the belt back on. I removed al the slack elsewhere in the belt. All suggestions appreciated as to how to get the belt over the tensioner pulley.
