4/5

I got it working on my To get my upper unit to work, I used a stand to hold the lower unit vertically, then I was able to lower it straight down.

Most of the shafts fit perfectly, but the oil seals are leaking or I was mostly satisfied with everything

3/5

In addition, the seal that goes over the water pump housing is a bit shorter than the previous one, so the tool that is used to press it down does not make contact with it. However, the shaft seal went on easily enough. A pressure test showed that I had quite a bit of leakage.

3/5

There is a slight difference in the length of the outlet between OEM and this housing. This part seems to have been finished off too much during the manufacturing process. I hope that it seals well.
