The mechanic that changed out the timing belt, when I first acquired my Patrol, didn't correctly torque up the harmonic balancer bolt. As a result, the belt retaining washer chewed into the shaft.
I had to change out the water pump a few months later, and this is when I discovered the blunder. I was lucky enough to get the washer to sit within a few thousandths of an inch when I torqued up the harmonic balancer bolt and it has run for nearly 80,000 ks.
The Belt and radiator a overdue to be replaced and by chance I saw this video, https://www.youtube.com/watch?v=7oq0UhOd5_8 on You tube.
Has any one used this method to repair a crank? Is it a strong / hard enough weld that can handle the stresses it would be subjected too?
I have a replacement crank, but it has a worn oil pump drive flat. Could this method repair it as well?
