The gearbox on my CSW was running fine (when it was on the road) until I changed the oil. Now 3rd pinches. Once I get back on the road I’ll send it away to be rebuilt. Maybe the old oil was masking something.
The mushroom breather is on the bench with a new potato stuck in the outlet. Got some doosel soaking the filter. I’ve scraped off the silicone bead and ordered a new o ring.
