Fuel Pump push rod bushing
Hi Gents
I'd like to know how to remove and then reinstall the fuel pump pushrod bushing? I want to remove it to be sure that the oil gallery is clean. This is in a model 59 block. Thanks so much Jim |

It is a very thin wall part as you know. I machined a special driver that would pilot inside for a good length and just fit inside the diameter of the hole in the block. The bushing is driven straight down into the cam bearing cavity. I can't remember if the bearing was in or out.

Re: Fuel Pump push rod bushing
Kahuna, Is it really necessary to remove that bushing in order to clean out the oil gallery?
I am just thinking you might be better off just leaving it alone, unless it's "worn out" , which I doubt. |

Re: Fuel Pump push rod bushing
Everdently you have the engine stripped to nothing. You have to remove the rear cam bearing. You make a driver that slides down the bushing a good inch, make the top of the driver just a couple .002 smaller than the outside of the new bushing, make a nice square edge where the driver hit the bushing. That is a very thin bushing and if you have a sloppy driver you'll will crumple the bushing have way down the hole and have a hell of a job getting it out. Walt

Re: Fuel Pump push rod bushing
Removing the bushing is a risky business, make sure you have a replacement before you start. Most guys don't remove them, clean the tube with a rifle brush 30 cal works great.

Re: Fuel Pump push rod bushing
I made a driver using a 3/8" bolt, cut down the head so it will go through the block that holds the bushing. The shank of the bolt goes through the bushing, use a punch to drive it into the cam area... I've removed a few and have not ruined one yet.
I reuse them cause the first one I bought- from a reputable supplier- was worse than the old one I removed. The ones I've seen don't seem to wear much. I have two or three around from ruined blocks, just in case. Ron, I must disagree with you... There's usually lots of crap in the oil galleries- I wouldn't be comfortable not cleaning every nook and cranny, and this is a big one... Karl |

Re: Fuel Pump push rod bushing
I stand corrected, only changed one and it wasn't anything I'd want to do again. However if you've never done this before, it's a great learning curve. I have the rifle brish on a drill and it works quite well along with a good flush.
