Dropped my Oil Pump

[STI_KLR]

I was attempting to put my new STI oil pump on the new block, but realized the main seal got messed up putting it on.

I took it off and attempted to get the seal out of the oil pump but it slipped out of my hand and I dropped it onto a carpeted floor from about 4' up.

It now makes a slight "click" sound and if you give it a slight shake, you can hear the internals move around. I never checked to see if it moved before I dropped it, so is this a normal sound? Or have I just obliterated my brand new pump? Is there a way to check to see if it's ok?

I really doubt dropping the pump on the carpeted floor hurt it. You are probably hearing the rotor shaking around in the housing although I don't remember it being loose enough to rattle. You will need to locktite the screws when you put them back in as a common problem is the back coming loose and the motor loosing pressure when the screws come loose. You should probably put some assembly lube in the pump on reassembly.

unless theres a dent or something the pump is fine. its stout and carpet is soft. the rotor has slight play but shouldnt knock much. i second needing to use loctite on the screws anyway.

You might need an impact screwdriver to get the back cover off. They can be pretty tight.

I second that highly!!

Grab a hammer and one of these http://www.sears.com/shc/s/p_10153_12605_00947641000P

makes like much easier. I use to use an impact screwdriver but after nearly stripping two screws found the old method to work much easier. They work great for the piston access plates on the back of the shortblock too.

I used my buddy's Snap-on drill. My god...I had no idea they were going to be as tight as they were. I was almost balancing on the drill with all my weight because the bit kept wanting to strip the screw out (thankfully, I didn't strip any).

Everything seemed ok - nothing out of the ordinary. I compared it with my oil pump I took off the motor and everything matched up. I used loctite when I put the screws back in and used the drill to achieve this.

*fingers crossed*
