u/Automatic-Branch-264

I ended up grabbing a 148-4736 final drive from aftermarket supplier and it arrived in under 7 days. My 307C was down and the local dealer was a nightmare to deal with on lead times.

The drive is installed and working as it should. It feels very durable, and the gear reduction is smooth as silk so far.

Since this is my first time using this specific aftermarket drive, how often are you guys doing your first break in gear oil change? I’m thinking about dumping the oil after the first 50 hours just to check for any initial wear particles, or am I just being over cautious?
