I have some assembly lube I might use, but I've read around on some other forums that others have just put it back together and it was fine without anything. I will probably prime the oil though, remove the fuel pump fuse and crank it a few minutes.

Cleaning and re-assembly will begin tomorrow morning, I'm finished for today.

 

if you have assembly lube use it, Vasoline is just a cheap replacement for assembly lube .

 

What I did was a very thin coat of grease with u-joint grease, then dumped gear oil all over the gears. After reassembly I filled up the oil filter to over flowing with oil, pulled fuse to fuel pump and injectors and cranked for about 30 sec or so. Plugged everything back up and started it and with in 5 sec the oil light went out. I did my gears as a preventative measure, once I got the old ones out they where actually in perfect shape. I was quite happy to see this as I was in the bad vin range with over 110k miles on the original gears at the time.

 

Whatever you do pull the fuel pump fuse so you can crank the engine till the oil light goes away.

 

LRScott,

the attachment Is that your oil pump ring gear broken in three piece or someone elses?

 

Its mine . Glad I caught it though.

 

I guess that is the outcome of the misaligned timing cover on 03’s. Yours is the third or fourth 2003 in the last year that people have posted pix of a broken outer ring in the oil pump, most just like yours broken in three pieces. The misaligned timing cover must put undue stress on the outer ring gear.

 

I was snooping around and had remembered when talking to a service manager about this awhile back. That he mentioned, when the issue occurred it was remedied with a different timing cover. I should have asked the part number.

On AB, there are 2 different timing covers for the Discovery II: Land Rover Parts, Accessories and Information . So, from the looks of things, the block was machined wrong when they made it, but the timing cover is what they decided to alter instead to remedy the problem. I looked on the front of my timing cover and it says "HE .1310148". Below and to the left of the cam shaft sensor, it has in 3 square boxes with the numbers, 01,02,03. SO, drowssap, I was wondering if you wouldn't mind or are able to look at your front cover on your 04 Discovery and see what it's numbers say.

 

the 04 in my avitar is another toy; one on my harleys. my disco is an 2000.

 

Whops. Hopefully someone else will chime in that has an 04. I remember seeing an 04 at a local scrap yard (sad sight), maybe they still have the engine and will allow me to take a look at it.
