I have a 1985 model 454 Crusader 350 engine and am trying to replace the fuel pump. The push rod is tight against the wall of the engine, hence i can't get the stem of the fuel pump in. I have "bumped" the engine numerous times and tried to move the push rod back to get enough clearance to insert the pump. I have tried to wedge a flat blade in between the end of the push rod and the engine case but can't move the rod. I admit this is new to me and I searched the forum for the answer to no avail. Help. |

As you remove the old pump, the push rod usually falls down and stops at the pipe plug. In this position the end of the rod is hitting the pipe plug. You can grease the rod and move it back "up" into the block, and the grease should hold it up as you install the new pump. Is this making sense? |

Sometimes, you can have a sluge buildup on the rod. when the pump comes out, that stuff will wedge the rod tight. If necessary, you can remove that plug and gently tap the rod up. Use a thin grease like Dave suggested and it should keep the rod in the block. you mmay find it beneficial to rotate the engine, by hand, to get the rod on the low end of its eccentric. Don't forget to replace the plug if pulled. |

Yes, thank you- I went back up and with better light and some contortions of the body found the pipe plug. It is still a tough fit--if the cam is at its lowest point will I be able to esentially get the pump nearly flush to the engine wall with just a little pressure. Right now I am about 1/2 inch away with out pressure. |

Tried rotating the engine using socket on the crankshaft pulley bolt. To turn the way the engine turns the bolt started to back out. Would it be alright to turn the engine backwards. i have the coil wire out. |

Is that a reverse rotating engine? If not, you're turning it the wrong way.

Ray - you can rotate it backwards, manually, w/o any problems. |

I'm turning it the way the engine rotates when it is running. I probably didn't explain the direction very well. That directions loosens the bolt that holds the cranckshaft pulley on. It is the normal direction to loosen a bolt. I can bump it with a weak battery as needed, to see if the cam, at it lowest position, will give me good working room to get the fuel pump close to the engine wall to facilitate getting the bolts in. |

That is your Right Hand Rotating engine. In the marine realm, engine rotation is determined by looking at the flywheel - clockwise=right, counterclockwise=left (handed).
The newer setups almost always use LH engines and change rotations with gears rated full power in either direction. |
