Title: WTB: Cranks pullys for AHU, 1Z, AAZ
Post by: fatmobile on June 05, 2026, 02:31:53 pm
The crank pullys on my friend's project are looking fried.
 Swapping the AAZ serpentine belt setup onto a 1.6.
The harmonic balancer pully is torn up where the timing belt rode against it and the v-belt pully is all bent, weak and rusty.
 part numbers:
 serpentine belt harmonic balancer pully 028 105 243 H (AAZ)or T (AHU).
 Fits most of the MK3 diesels.
 And the v-belt pully 028 105 253 A not sure what it comes from.

Hello Craig, I have a New 028 T harmonic balancer. Never used it.
Also in the hoard I have an 037 pulley for 9.5/10mm wide belt that might just be a tad smaller diameter than the 028. Fits perfectly into the balancer.
make an offer on the 028 T harmonic and the 037 is free, if it fits, awesome.
Some pics and measures...

 I'll check those measurements against the v-belt pully.
 And I'll see what Aaron wants to pay.
 Was kinda hoping for a cheap used one.
 Hate to grab a new one out of your stash for this used 1.6 engine.
