YD25 D22 UPGRADED OIL PUMP

 D22 OIL PUMP DESIGN ISSUES

With a standard D22 engine the sump must be removed to remove the oil pump. The first photo shows the oil pump backing plate protruding into the sump. This is why the D22 sump must be removed first.

The second photo shows the oil pump with our upgraded oil pump backing plate installed.  With our backing plate we have machined the section that drops into the sump, a fitting is then inserted into the sump to make up for the material removed from the backing plate. A oring is used to seal between the oil pump and sump like a d40 setup. With our back cover kit fitted the oil pump can be removed without removing the sump.
