mTDI / TDI-M Injection Pump FAQ

[dieselherb1]

I have a 1Z engine. And now I have a ALH engine, needs head rebuilt. Car had a underhood fire melted all the plastic onto the engine, burnt the wiring, 2002. Does the 2002 ALH IP have a 10 or 11mm head? Manual trans.

[Hey]

10mm pump

[dts67]

He means the adjustment of the shaft on which the governor gear/flyweights are mounted.  It is normally inaccessible due to the pump bracket being in the way.

 

So adjusting this increases internal pump pressure ie more advance? Or am I missing something from previous posts?
Thanks

How do I know what Bosch VE Pump I have or am looking at buying?
The Bosch part number on the Bosch VEs pumps are fairly standard i.e. 0-460-4XX-XXX VE , what are important to note are the 6th and 7th digits of the Bosch Number. The 6th digit indicates the plunger size, 9 for 9mm, 0-10mm, 1-11mm, 2 for12mm. The 7th digit the is the application, 4 for 4cyl., 6 for 6cyl., etc. The specific manufacturers part number may also be on the pump and completly different, for example, the Cummins 4BT injection pump numbers do not indicate plunger size, everyone I have seen to date has been 12mm. Since the 4BT is a 4 Cylinder engine we can assume that part.

The only way to know for sure is with the Bosch part Number.

I don't know if this link has been posted before but it is very useful for crossing Bosch and vehicle manufacturers P/Ns and even finding #s for indevidual pump parts by application.

The pages take a minute or two to load.

enjoy.

Ok...... so I am trying to get a grip with the Bosch or VAG part number for any VAG 11mm (auto trans) electric pump. From the first quote (which seems to make logical sense) it would appear that there would be an 0-460-414-XXX pump that would be fitted to a VW application, but I could not find one on the list in the 2nd quote.
Does anyone have any actual part numbers and application that I can use to trawl through E-bay / scrapyards / classifieds please? So far every "breaking TDI" I have emailed on ebay has come back with a 0-460-404-XXX, regardless of transmission.

Or could it be that there are some 11 mm pumps with 0-460-404-XXX part numbers?

All bosch pumped ford transit 2.5 di's, the 'smiley face' ones, my '95-'99, have an 11mm head, thats what I used. Common as muck and cheap as chips!

Hello. i have some problem's with my m-tdi engine.
i have engine from arosa 1.7 sdi with injecitons from 110Km tdi.
my pump is from fiat croma 11mm and afn camplate.
timing is from 1.9td dualspring,
and my problem is to find a way to regulate the timing?
did something wrong with gov?
i have gov from corma and do i must take go from transit because i have gov sleeve from this engine. this sleeve is much longer and it have 23,7mm  , sleeve from 1.9td and fiat croma have 20,7.

The engine with gearbox 4t 020 from golf mk3 td  takes something about 5,5 litres/100km .
does it good result?
i modified the Principal lever with easier way and i think it work perfekt.

Are you trying to figure out how to increase timing advance as rpms or load increase?  If so I might be able to help.  Can you be more clear on what you are wanting to achieve?

[jabcok20]

how to increase timing advance as rpms or load increase

yes my problem is this. I have gov with 2 springs and i think i must put 1 spring form maybe transit...
what do you think? i think gov gives too much of oil injection and i hear early inject,  then when i change pressure(for liminate early inject ) car in the morning (when i start engine it ) smokes white and interrupts.
sory for my english:]

[410]

When you say "I have gov with 2 springs", are you talking about "Timing is from 1.9td dual spring?"  I just want to make sure we are talking about the same thing.  Also, is there another electronic solenoid on the side of your pump that looks the same as the stop solenoid?

Do you know how to adjust the internal pressure in the pump.  I can help but this thread might not be the best place to discuss this.  You can pm me or start a thread in the tdi section and I can help you there.

no timing springs from 1.9td dual spring and electronic solenoid is cut of with grinder:]
and gov from upper side of pump;) is with 2 springs and a transit have 1 long spring ...
now i take dose up and did gentler gov.

PM sent

[Hey]

Selenoid is cut off? Did you drill the channel on the back of the governor axis to allow timing to move with load?? If not.. this is a problem. Also, 1.9td regulator wont work with 11mm pump!!

I have been running my m-tdi pump/car for a long time now with absolutly NO PROBLEM.( 30 000km) The winter starting is MUCH better than my old 1.9td car.
As for the economy, I made 4.63l/100km (60.7mpg or 50USmpg) at 120km/h lots of higway and some visiting (calculated from a trip to Boston with 5 people in car) last spring. In a mix of highway/town it is around 5l/100km with hard acceleration. Timing at .42'' (1.05mm). I also have NO boost pin at all.

I have a VNT17Va at 20psi and some smoke close to the end but the clutch slip in high gear anyway and EGT climbs to 1300F-1400F fast when smoke occur.

It's nice to see you posting again Hey.  Your input is always greatly appreciated!  Because of your info I am also enjoying my injection pump.  I am running 1.9td regulator with 11mm head with no problems though.

does the AAZ IP bolt right onto an ALH?
