Olá a todos, espero que estejam todos bem.

Após realizar diversas medições, concluí que meu motor apresenta folga axial no virabrequim. Todas as medições que fiz mostraram mais de 0,40 mm (cerca de 0,016") de folga axial no virabrequim.

Descobri isso depois que o carro parou de repente enquanto eu dirigia. Fiz um diagnóstico e encontrei uma falha no sensor de posição do virabrequim. Depois de instalar um novo sensor, comecei a ouvir um ruído alto que parecia ser o disco de acionamento (roda relutora) raspando no sensor. Foi então que decidi medir a folga axial do virabrequim.

O que normalmente é recomendado para corrigir adequadamente o deslocamento do virabrequim? Quais peças são geralmente substituídas durante o reparo?

Existe algum reparo temporário que possa ser feito apenas removendo o cárter de óleo e trabalhando por baixo do motor, ou a desmontagem completa do motor é a única solução adequada?

Qualquer conselho de pessoas que já lidaram com isso será muito apreciado. Obrigado!

Hello everyone, I hope you are all doing well.

After taking several measurements, I concluded that my engine has crankshaft end play. All the measurements I took showed more than 0.40 mm (about 0.016") of crankshaft end play.

I discovered this after the car suddenly stopped while I was driving. I ran a diagnostic and found a fault with the crankshaft position sensor. After installing a new sensor, I started hearing a loud noise that sounded like the drive plate (reluctor wheel) scraping against the sensor. That was when I decided to measure the crankshaft end play.

What is typically recommended to properly correct crankshaft end play? Which parts are usually replaced during the repair?

Is there a temporary fix that can be done just by removing the oil pan and working from underneath the engine, or is a complete engine teardown the only proper solution?

Any advice from people who have dealt with this would be greatly appreciated. Thanks!
