One of the two jobs I unfortunately had to redo recently; cleaning the gearbox extension. I put everything together after I cleaned the alloy part in question thoroughly in 2018. At least that was what I thought. Fast forward 8 years and I found what looked like old grime and oil was coming to the surface of the alloy gearbox extension.
Time to redo the job and hopefully this time with a better end-result! First step was thoroughly washing the casting in very hot water with a good degreaser and a collection of different brushes. This removed a fair amount of grime and oil. Actually much more than expected. The water was pretty black afterwards. Needless to say, the extension was rinsed of with lots of clean hot water. After which it was time for an extra treatment, blasting the alloy parts with glass beads. Well pleased with the end result! Hopefully this time I got rid of all the oily muck in the casting.
And the final step was fitting all replated steel parts back to the gearbox extension. All rather straightforward. I only have to adjust the reverse gear baulk plate to its correct position. But for that the extension needs to be fitted to the gearbox.
