Good morning. The 901 on my project has already been removed from the car. I need to open it up to replace the 2nd gear synchro and it obviously needs to be clear clean clean before I do that.

Is it safe to pressure wash the exterior case so long as I don’t spray where the input shaft is?

And been there / cleaned that tips to share?

Thanks!

Never tried oven cleaner, but Gunk Engine Cleaner stuff works pretty good, especially if you do it on a hot day in the sun. Spray it on and let it sit for 15 minutes then use a stiff plastic brush and a tub of really hot water to loosen and much grime as possible, and hose it off.

Wish there was a good way to catch the oil and grime. Can't be good for the environment rinsing that stuff into the lawn or storm drain. Going to a professional steam rack is probably the most environmentally friendly plan.
