Hello, how could I remove the oil pump of a 235 engine without to remove the engine? One problem(?) the heads of the srews that fix the oli pump have round heads Is that normal or are they damaged? Ask Wolfgang
A big grin I found the reason of the bleeding oil pump Hello, I found today the reason why the oil pump couldn't made enough pressure the pressure got lost if the engine was standing still for a day. :-(( The oil pump has a valvet that must work if the pressure gets to high. This valve has a small steel ball, a spring and a pin to fix all. I take pressure air and blow it into the oil pump. Normally I think the valve should open about 6 or hight bar. I had a pressure under 1 bar and the air was coming out of the valve. :-(( So I remove the oil pump and take a look what ccan be wrong. I push out the pin, take the spring and have a look after the ball. But there was no ball. :-(( I meassure the borehole take another ball from a bearing and put it into the hole. Fix the spring over the ball with the pin and blow air into the pump. And great pleasure the valve works. ) I think some of the workers how build the pump had lost the ball and put only the spring into the pump and said okay thats all for today. What a fool! Happy Wolfgang
