Edelbrock 2650 stage 2 pulley alignment issue

[Woopaloop]

I'm having an issue where the belt is walking back towards the engine block on the tensioner.

Any tips on pinpointing the issue?

how many miles on the kit ?

2600, it's been an issue since the begining I've had to replace a belt already and this belt is getting torn up on the side facing the engine block.

Do you happen to know if the block was drilled from factory and/or the brass spacer was fitted?
(I’m assuming the stage 2 kit uses similar parts to the stage 1 up to a certain point)

Your top left idler looks different than mine. It also appears your belt is routed incorrectly.

The stage 2 uses a different routing apparently...

OP has a 2018, different than 2016 apparently.

It was done by Ford, I'm sure it was done properly I just cant seem to figure out what is out of alignment. It seems like maybe the bracket isn't close enough to the block and the tensioner is too far away.

Is it possible that the spacers got jacked up at step 43?

The spacers were installed correctly, however I think I found the problem. The center top bolt on the bracket isn't seating flush with the engine block. It's possible that the casting was a tiny bit off or is slightly out of tolerance. This is causing the bracket to not be parallel with the block and is slightly angled so that the tensioner is further from the engine block than it should be.

I believe the solution will be to shave down the block slightly where it's hitting allowing the bracket to sit flush.

What worked?

What worked?

I havent gotten it fixed yet, but I havent gotten on it very hard since this issue first started.

I'm getting some more upgrades, eventually I'm going to take everything out and fix it when I put in some 1300cc injectors, fuel system, and others.

I'll update this thread when that time comes.

I had the same issue across multiple engine long block/timing covers. I got the stock measurements and verified with a slide gauge the stand offs were correct length....I had to have them milled down to bring the plate into alignment with the blower pulley using a straight edge loaded from tensioner to blower pulley then blower pulley to water pump.and water pump to crank all where inline except the tensioner mounting bracket so I had them milled down and its tracking perfectly..
Just an FYI......

Had to mess with the torque sequencing on the mounting bracket bolts in order to get mine to lay flush. Verified pulley alignment with laser before testing it on the road.

That's extremely useful, I will do that. Thank you!
