Mercedes OH1418 Gearbox

Post by Mercoh1418 »

Hi all, I'm new to the Bus Australia site, and new to owning an old Mercedes Bus.
I have a 1993 Mercedes OH1418 converted to a motorhome.
It hasn't had the love its needed at some point and the gearbox has suffered as a result. When I bought it the box was really stiff to change gears, I drained and refilled the box and heaps of metal filings came out, I then added fresh oil. It now changes ok but (it's a 5 speed) 4th gear sounds terrible and vibrates through the vehicle. Seems like it was the most tortured gear so I've added PTFE treatment, twice. Each time it has made changes easier and reduced the harshness of 4th gear but I still feel it has a limited lifespan.
Is there and suggestions of where we should turn to for a changeover gearbox - ideally a 6 speed if it bolts straight in to reduce highway engine speed.
Many thanks, Nick.
