420A Hydraulic ---> Mechanical tensioner belt now walking out

[GSTurbo1]

Ok, about done with my rebuild... I followed all the instructions that came in my gates kit. Got it timed perfectly and belt perfectly tensioned, now when I turn the crank by hand the belt walks out maybe a 1/5 to 1/4 of an inch. I did a little more research on the web and it seems that most people cut the hole out on the inner timing cover like shown here 420A Mechanical Conversion Kit Images. Should I take the timing belt back off and cut that part of the cover out? Or is it something that is normal and will straighten out as it runs? Honestly, I don't want to take it back off but can, it's just the fact that i'm doing it myself and struggled big time to get it on.

Yes you must cut the inner timing belt cover. Then tensioner will not sit flush without cutting it.

Are you using stock cam gears? I have gates on my car and didn't have that issue.

yes, cut the inner t-belt cover. I thought i would be ok leaving mine without cutting and about 100 miles on the tac and i noticed some wear starting to develop on the out side of the belt. i fixed the problem before it got worse, also just to be safe i replaced the belt( I get a little paranoid).

Most peope? More like Everyone.. Since you HAVE to cut the hole out for it to sit flush.. Thats ###### the issue. Fix it and report back

Well cutting the hole out that was marked instantly fixed the problem.

Hi, this thread is so old the link to the picture doesn’t seem to work. Could anyone post another pic where this hole needs to be cut. I am having the same issue on my engine. Thanks
