I know both the 2 447 010 033 and 2 447 222 125 Bosch primer pumps fit our Toyota B and 3B diesels. (From info I've got from MUD.)

And I am pretty sure that some Mercedes Benz diesels are being fitted with these same pumps.

Now my problem is that I'm trying to locate a replacement primer pump on the Internet and almost all the vendors are aiming their sales at Mercedes owners. So even when they are selling Bosch pumps, they simply say which Mercedes models they fit (rather than telling me the Bosch part numbers).

For instance one vendor says : "fits all Mercedes diesels 1977 to 1985 (except 190D 2.2)"

Another says "fits all MBZ diesels 1968 - 85 220D, 240D, 300D, 300CD, 300DT, 300TD, 300TDT, 300SD, 300CDT"

At the moment they seem reluctant to reply to my questions. (Or else are replying that they won't supply to NZ.)

Can anyone tell me which Mercedes models have the primer pump interchangeable with ours???? (If I know this - I can perhaps order one without having to ask them anything.)

Thanks in advance.

I thnk the VW primer pumps on some models also work

Thanks Rosco. But to help me order one - I really need a specific model (- preferably with the year of manufacture too but that isn't quite so important).

And as I say, Internet sales (that I find with my "search engines") seem to be aimed primarily at the owners of older Mercedes diesels.

Actually I found what looks like a beautifully-made pump (after-market german-engineered but non-Bosch "screw-to-stow type ") but again the seller simply stated which Mercedes diesels it fits.

After my recent experience - I want to go for a reputable manufacturer who says specifically that their product is designed to avoid leakage. (Perhaps a lot of people don't mind diesel dripping all over the place for the brief period when they're operating the pump. - But I certainly do mind!)

(The original Toyota one at least lasted a couple of decades before it began to leak - And I don't want to waste my time fitting a "dud one" again. :D)

Dont they have walk in places over there where you can buy parts over the counter.
I know you have trains:D
 
My Isuzu one looks very similar. Also made by Diesel Kiki (aka Zexel aka Bosch) and also fitted to a type A injection pump.

I'll try to get some numbers tomorrow. Mine also leaks when not screwed closed.

Perth and Wellington probably aren't too much different in size so I don't think either of us would have a lot of choice in diesel specialists Rosco. And aussis and kiwis are both similar in their "laid-back attitude" - So I can just imagine how the conversation would go:

"I'm after a quality primer pump for my Toyota B diesel".

"Yeah I'm sure we'll have one here. Just bring your old one in and we'll sort you out"

"What brands do you stock and what's the likely cost."

"I dunno about the brand. Probably Denso. We don't stock rubbish you know. As for the cost - depends on which one you get. Anything from $40 to $80 probably"

"Would it be of the 'screw-down-to-stow' type."

"What?" (Whispers to mate - "Got a right timewaster here."

So if I can, I much prefer to order on the Internet where I can study the product at my liesure and know much more detail about what I'm getting. (As well as get a good price.)

Try this link. Mercedes-Benz Forum - BenzWorld Model Guide

If I did it correctly you will be able to cross reference MB car models with their engine families. From there you could order a pump primer based on model, year and motor.

Hope this helps

don't have trhe answer to your question but here's a site offering the part



(in German, try babelfish.altavista.com for a translation).

prices seem higher than what one could get by shopping around - he'd probably ship anywhere for the right amount of cash.

Thanks. This has all been most helpful.

Bosch themselves seem to have complicated matters. They are such a MASSIVE company and that they don't seem to have any rationale in their part numbering system.

It's rainy and cold today - Good day for doing more Web research.

JoeTLC site says the 2 447 010 033 (known to fit our diesels) also fits Mercedes 220D, 240D, 300CD, 300CD turbo, 300D, 300D turbo, 300SD Turbo, 300TD and 300TD turbo.

My research also shows the thread is M16 x 1.5

And I believe, since Bosch 2 447 222 126 is advertised on eBay for 240D, 300D, 300CD, 300TD and 300SD --- that it is near-enough identical to 2 447 010 033 and 2 447 222 125!

So what have I done? I've ordered TWO Bosch 2 447 010 038 for $US52 delivered to my door in Wellington from Arizona USA.

Why did I go for that part number when it is different from any that I've mentioned before? Well because it is also said to fit those same Mercedes models. And it comes from a supplier that Mercedes-freaks seem to prefer to use. They have a reputation for fast delivery and low prices as well as for "good gear".

Here are some photos I've scavenged of various Bosch pumps:

The place I've dealt with before are called Entech and are based in Nelson.
I needed a new diaphragm for the aneroid in my injector pump, after giving them the pump numbers they were able to give me the choice of genuine zexel parts or aftermarket generic parts.

I'll PM you their phone number.

So why did you order two? If you want to sell one, let me know.
 
Tom,

As I posted in your other thread(the bad one) I have this primer pump in my 3B, not sure if there is a difference in B and 3B.

The number on mine is 2 447 222 126 - different number but looks exactly the same and have had no problems.

again, not my photo stolen from a mud thread....

I sell and use that exact primer pump. It's much nicer than factory....no leaks, and it's a common 17mm nut that installs it. Import Purist Land Cruiser parts
 
Thanks for all your help.

Hey - I just noticed that the 2 447 222 126 pump in my photo is sitting on a box with the 2 447 010 033 part number on it?? The Bosch part number system completely baffles me.:frown:

So I think it is fair to say that we know the following Bosch pumps all fit our diesels (3B and the less common B diesel - and probably the 2B - as well as the 13BT, H and 2H engines of course):
2 447 010 033
2 447 222 125
2 447 222 126

And I've ordered 2 447 010 038 so that'll be a test to see if that one fits too. (It'll be embarrassing if it doesn't!)

And I haven't yet heard of anyone whose using a Bosch primer pump complain of leakage. (Which is one reason why I went for one of these. Other reasons are the small size, the fact that Bosch proudly displays its name on these products, and the fact that most literature implies they are "better than OEM".)

Actually I must try to enlarge that tiny photo when I get back home tomorrow because it shows the construction of the Bosch pump and that may explain why they seem to perform well. (If I can get it any larger?) ......done - Sat 24 May 10.40am NZ time

I note that my supplier doesn't guarantee the pumps I ordered for biodiesel though! But I think that is just "an honest supplier protecting itself from the unknown".

Oh - And I did order the second one as a spare - partly because it would probably make sense freightwise and partly because I get a sense-of-security from the "screw-down-to-stow" feature that is missing from these pumps. (I always imagine that mechanism is sort of like "shutting off a water tap" - compared to "leaving it open with a hose connected".) But perhaps I'm just a worrier?) PS -Freight more than doubles the cost of these items for me since I live so far away. But I think it still works out cheaper than if I were to buy them here!

:cheers:

I ordered two primers, one for my 1977 300D and the other one fit my 3b. So if it's good for a 300D I think your fine.

The 033 sounds familiar.
 
126 is what I put on my 13bt....though I'm not sure it makes much difference from what I have seen.
 
I wonder why it is that some suppliers in the USA are so good to deal with yet others just can't be bothered with overseas orders at all?

"Autohaus AZ" are GREAT!

On 23May I ordered 2 Bosch primer pumps from their Arizona-based premises and I received the pumps here in New Zealand on 3 June. and I would have got them far sooner if my credit-card-issuing-bank had "played ball properly" with AVS (- the "address verification system" used to combat credit card fraud).

But - Hey - I can pay by Paypal and that has it's own independant system for preventing fraud. So why don't other USA companies behave like Autohaus? (Harbor Freight won't even reply to me. Update 5 June NZ-time: Harbor Freight did indeed reply to me and apologised for their delay in doing so!)

Anyway here is a photo of the primers:

And getting them has helped me understand the Bosch part numbering system a little better. I now realise that I know of only two Bosch primer pumps that fit our Toyota diesels. The confusion (and why I thought there were more) is cause by each primer having two different part numbers - one for the box it is packaged in - and one printed on the pump itself.

So these two primer pumps are:
2 447 010 033 (box) / 2 447 222 125 (pump) and
2 447 010 038 (box) / 2 447 222 126 (pump)

Ooops. Looking back at the photos after I posted this........ It looks as though any box labelled "2 447 010 033" or "2 447 010 038" may contain either a "2 447 222 125" or a "2 447 222 126" pump. Anyone can enlighten me further on this? (So if you were to order based on the box part number you would order either a "2 447 010 033" or a "2 447 010 038". And you would get either a 2 447 222 125 pump or a 2 447 126 pump. Hmmmmm. Why would they do this??)

Now all I need is for it to warm up and stop raining in my workshop so I can fit one of these Bosch pumps (and rip out that heap of junk I installed a few months ago)

:cheers:.

So what is the difference between the two pumps?

The colour of the writing on the plunger.
The colour of the protective cap fitted to the threaded end.

Anybody know of any significant difference (such as having the internal seals made from different materials making them suitable for different fuels)? ...... Cos I don't know of any significant differences.
 
I wonder why it is that some suppliers in the USA are so good to deal with yet others just can't be bothered with overseas orders at all?

Well, there is more work involved to ship overseas...more paperwork at least. Paypal makes the money easy, but they charge a hefty fee. Ask me how I know. :(
I don't mind shipping overseas, but if I had to do it all the time I would want to charge for "handling". Not specter fees mind you, but something.

Good point.

I suspected the higher vendor-fees associated with Paypal was why Autohaus went with my creditcard instead.

Interestingly - Most USA-based companies won't accept my credit card - which I now think could be related to the problem with "AVS".

The thing is - You have such keen vendor-competition (and such a BIG local market) in the USA that your prices are sometimes WAY lower than elsewhere. So even if I add the high shipping cost - I can still get the goods cheaper (if I deal with Internet-savvy companies that know how to obtain/charge reasonable shipping rates - and SOR and CCOT don't really fit that description yet).

In this example - those Bosch pumps cost just $US12.04 each and I ended up paying $US28.50 for shipping/handling. So the "landed cost to me" of $US26.29 each was still worthwhile! And even more important - I got exactly what I wanted.

When converted to NZ dollars and all fees are considered - Each of these pumps cost less than the "unbranded failure" I purchased in this part of the world a few months back.

(Hmm. I hope I'm not premature in praising the Bosch pumps cos I have'nt fitted one yet :hhmm:)

Anyway- This post could be useful to other kiwis dabbling with Internet purchasing for their cruiser parts.
