looks like there are two different size threads on merecedes motors prechambers.Does anybody know if this homemade tool will be compatiable with 89 190D 2.5 motor.
thanks

well i will answer my own question. 89 2.5 prechamber has same threads a injector which happened to be the same as dodge caravan axle shaft, nissan pulsar, saab axle / axle shafts. i used caravan's axle's outer end and slide hammer to pull it out.
