Good day all!!!
Thanks guys and gals!!!
So, today I was bored and only had stuff to clean... Still no new parts... Got an email stating that they had to wait on some parts from "BMW" and would get the stuff sent out as soon as the complete order is together... That will "learn me" to order everything at once...
I found these in the hardware for the valley pan... I have a bunch of hardware left over from my other projects and actually had exact matches for these... I think I also have to replace a few from the rear cover too...
Oh, probably to the disapproval of some out there, I refuse to put a new cover on the rear and valley pan because they don't just sell the gasket... And, it begs the definition of insanity to keep doing the same thing expecting a different result... I'm ditching the factory seal and going 100% high temp sealant... I don't feel like pulling the stupid thing back apart cause of a coolant leak at the rear of the motor...
This is the oil pump... I don't think anyone has pulled this apart to see what it looks like on the inside, so I figured I would... To my surprise, I found the top filter spring inside the pump...
Here is the dirty pump pulled apart... I did have all the bolts in the location they came from, but they fell out moving to the work bench... So, that was a puzzle too...
Don't forget about the spring...
Goes here...
These go here...
These have dots on one side... They weren't facing the same way for some reason... I doubt it matters and was just put together in Italy this way... It is hard to see the dot on the ring... It is at the top of the ring...
Sleeve locks drive shaft in the pump...
They can't get mixed up if the pump is to actually work again...
I figured out that all the bolts needed to stick out this far prior to tightening...
The longer, thinner tube will start before the larger pipe so no fighting in getting them both started...
You should turn the drive shaft while pushing the end piece on... it is a tight fit, so be patient!! This locates the end piece, but it would be better to tighten these with all parts locked in where they should be first...
This is what it should look like when it's on all the way... both machined ends should be just barely visible on the large pipe... the thinner tube is squashed in place...
The mounting bolt hole for the side with the drive shaft has almost no clearance compared to the other five mounting points...
All four main parts had engraved numbers... none matched...
This is the pump pick-up screen... This is stout!
and goes here... Gasket goes on next... and this can get put on backwards...
Getting these lock rings out wasn't too hard once I figured out how... This method is dangerous!! I had one pop out and landed outside of the garage... Cover with your hand and use the pliers to hold on to it! Only the one tip of the pliers is in here...
Put one end in and get the pliers under the ring... squeeze ring with the pliers and push down until it pops out... violently...
It is a shame I had to buy whole new parts... the plastic part, with it's own part number, is the only thing that needs to be new...
These looked nearly new... by comparison of the other 4.4L BMW motors I've done...
And the best part of the day... Trying to get this plug out, I discovered a previous owner or shop tech over tightened the drain plug and rounded it out fairly well... Not sure if yous guys and gals know, but there is a torque setting on the cap itself... one for the plug and one for the cap... Sheesh!!! I need a new drain plug... No normal bolt will do...
Oh, one more thing... I took the center of the filter housing out... Just cause... it seemed as if the machining of the threads didn't go well... it broke some threads coming out and the plastic threads looks wavy in one location... I've never had issues taking them out before today... In the event they do that on purpose (instead of using Loctite), I'd advise you leave yours in place...
That is about it... I did clean up the chain covers... oil pan is next... maybe I will get some parts soon!!!
Cheers all!!!
