[Vwdiesel] Help! '04 TDI tensioner trouble

[Shawn Wright]

Installing the TB kit on my '04 Jetta, the new tensioner appears to be
weaker than the original (both are Litens, but the original has a VW part #)
as follows:

The material for centre hub is crap pot metal - the hex key is stripped
after two attempts! OEM is much harder material.

The metal tab which fits in slot just bends and pops out of the slot when I
try to tension to correct amount. I am keeping the 15mm nut snug as possible
while tensioning to keep it flat against engine, but the soft metal tab arm
just twists!

I fear I have just ruined a new tensioner with very little effort. Am I
doing something wrong? I'm following the guide for BEW engine at
myturbodiesel.com

Thanks
