You are right the 300D NA has larger gears then the 240D....a new 240D pump is 89$...the 300D 600$...

I am going to post in the classifieds for one, if no luck I will bite the bullet on a used one on ebay...no wayyy I can afford a new one

I've got to dash off and get the children from school so I haven't got time to answer the first part of your question. I have found the second bit 127 is hidden away in the "engine housing" part of EPC

I can see it is part 149 in the picture shown on the Russian EPC

Êàòàëîã MERCEDES

The Russian EPC doesn't give a part number for it though. With your grown up EPC I bet you could though!

(I'll try and answer your other questions later on today after we've finished making pumpkin lanterns - oh the life of a busy mum!)

AH no wonder I couldn't find it in the epc...checking that out now...

Enjoy all Hallows eve! Tomorrow is the start of the new year! Not many people know that. I will be handing out candy...but our tricker treating starts at 4pm and ends at 7 I believe...so I won't be able to put out the black lights, lord how things have changed..

Plus I am still figuring out where to find the coin for this repair...so we have time

cooljjay · #34 10-31-2014, 04:57 PM

Ok well it seems that bushing is in the engine housing, like the epc says. I went out and looked in the hole, after I found a picture of it. I can see it there but it won't come out...so imagine it is pressed in...

So here is a pictorial of the assemble, that is under that cap on any non turbo 300d, 240d, 220d etc..

here is the setup, left to right thrust piece, helical gear, oil pump shaft.

It is suppose to sit this tight in the block, no gaps between the three pieces but this is how mine sat because of the worn thrust piece.

Here you can see how the thrust piece sits on the gear and on the second pic you can see the gap of material missing.

So this is where the metal clank sound was coming from, since the shaft was not tight, a space worn between the gear and the oil pump shaft....this allowed the shaft and gear to clank aka hit each other.

So I really really need a new gear set, oil pump and thrust piece but I have no where near the 1000$ it will cost for new parts. So I am going with a used oil pump, used gear "if" I can find one and a few new seals/gaskets.

Not 'trick or treat' but Pick n' Pull !!

vstech · #36 10-31-2014, 10:20 PM

If you can't find anything closer, I'll be scrapping the euro 240this winter...

cooljjay · #37 10-31-2014, 10:40 PM

Sweet, well when you scrap it...you better pm me!! I want or should I say need a big box o parts...including that blower...

I'm thinking pick n pull but we don't have one

I am going to see what is down in phoenix...that is a long drive and fuel cost but it may be cheaper...

Decided to give candy away tonight, think we gave around 50lbs away...

Can you believe it, there other simi closet 180miles has 2 240's and 3 300's but they are all 82 which are turbo....debating on going there for the gears but still need to find an oil pump.

Stretch · #39 11-03-2014, 04:38 AM

I have seen the gears for sale but they were Febi (spits as he types)...

Stretch · #40 11-03-2014, 04:40 AM

Oh and I guess you don't need the other part numbers for the oil pump if you are going for a new one.

(If you have the part number for the bit in the block it would be nice if you are willing to post it up so us poor folks with no grown up EPC know what it is!)

cooljjay · #41 11-03-2014, 02:31 PM

Oh agreed febi doesn't sound great....but the price tag on the gear set is 600.00$ little pricey for febi. There are 2 240d's in a simi close junk yard so I am going to go pull both gear sets, I want a spare.

I found out that there is a snap ring in the oil pressure valve but I can't get it out or should I say no idea how to get it out. So that is where the spring, etc is.

So here are part numbers

gear set 1300500306

bushing in block 6151810026

Thrust piece 6151800144

Thrust piece seal 6219970040

I can't afford a new oil pump so I am looking for a good used one, probably will just replace the one gear shown as I don't want to remove the injection pump, vacuum pump etc to remove that gear set. As well as the thrust piece and seal, I believe this will surface for awhile.

cooljjay · #42 11-03-2014, 05:57 PM

Crap....I screwed up...I got the wrong thrust bushing....I seen 3 part numbers, assumed they had just upgraded the part or what not and changed the number....I see that it goes by engine number....but I don't get what the epc says..

part # 1261800044
Up to engine: 910 12 027647
Up to engine:
912 12 003544 EXCEPT FOR 003437-003450

FROM ENGINE
912 10/50,20/60 170720
912 12/52,22/62 146805

I bought the last one, so any help here??

ok ok I think I get it, they redesigned the gear at some point, looking at this picture of the gear set...you can see the extra spacer...

here is the new one vers the old one..

So my theory is that mercedes new about this issue happening and for the later year NA's they redesigned the gears and bushing so there would be less friction and less wear. This would explain why my euro na with the same miles doesn't have this issue....

Heh, so now you REALLY Want my 84 euro 240 oil pump eh? Likely you want the m pump as well?

Nooooo how many times do I have to tell you I want the whole car

Can you get it in a flat rate box...I'll pay for the large size to make it easier

Sadly the 240's have smaller gears inside of the pump, so it wouldn't do the job...though it would fit...the gear and thrust piece will...hints to why I am willing to drive say 400 miles to get to the 240's..

Stretch · #45 11-04-2014, 02:09 AM

Well you are doing great research on this - as frustrating as it is - keep it up!
