After market Bosch turbo compatible pump

[Peterr]

Anyone tried one of these new after market pumps ?

0460414154 VE4/11F2000R711

For OTOSAN 2.5L-DITC 74KW

Would it be compatible with my Transit turbo diesel 2.5 1997 engine 4GD ??

Apparently made by Ford in Turkey.

I have a pump like this; I used it for a naturally aspirated engine, which I installed a turbocharger on myself.
After installing the turbo, the engine became noticeably more powerful.
I noticed this after installing a 2007 Transit rear axle with a 1:3.31 reduction on my '90 Transit.
Without a turbo on this axle, the car doesn't want to move at all.
But with a pump and a turbo corrector, the engine produces high torque at relatively high RPMs—over 2000.
With a standard pump and a hydraulic corrector, after tightening the hydraulic corrector screw, the engine produces high torque at lower RPMs—around 1500—and pulls great from idle.
If you have an Otosan pump, install it and don't hesitate.
However, after replacing the pump, you'll need to adjust the pump to achieve maximum engine efficiency.

Thanks! I just ordered it.

PUMP 0460414154 VE4/11F2000R711 For OTOSAN 2.5L-DITC 74KW

It has the LDA head so I have to add the tube to the air intake as is the photo. I’ll have to drill and thread the hole one air intake.

I was wrong about it being made in Turkey. These are made under license in China

These pumps are now manufactured in China, but I received a Bosch pump for Otosan as a gift.
There's a guy in Russia who repairs Transit 2.5 diesel engines and fuel injection pumps for them and runs a video blog about it. He recently posted a video about installing a Chinese fuel injection pump with a turbo corrector on a Transit.
My first impression of this pump is positive.

cherniy_chack,
I’ve taken my 145 and 146 to an old-timer diesel specialist. I know one or both of these pumps could be fitted with an LDA. You mentioned having done it. I would like to give it a try. Create a specific forum topic for it if your willing to guide me through it. I have a second engine. No turbo but was thinking of pulling it out and working on it and adding a turbo. So I could use a second LDA pump. Only 140,000 km on it.

[Peterr]

Do you have a link to the Russian guy’s channel?

My new pump is being prepared for shipment. Anyone know why there are two tubes from the fuel return on the pump?

Here's a video about this pump.

I'm not advertising it for the simple reason that Russia invaded Ukraine in 2022, and advertising enemy products is utterly stupid.
But I'm doing this at your request.

[cherniy_chack]

Peter, instead of these Chinese tubes at the inlet and outlet of the pump, you need to leave the original ones from Transit.

[cherniy_chack]

Peter, I have an original Bosch VE fuel injection pump, part number 154.
The LDA is installed there by the factory.
I read on a French forum about someone installing the LDA mechanism on some Bosch pump, having removed the LDA mechanism from a pump for a different engine brand.
But I haven't done that. And I won't do that—in my opinion, an engine with a standard hydraulic corrector, after adjusting the hydraulic corrector, provides a more comfortable ride due to the higher torque mechanism at low rpm.

[Peterr]

Thanks Cherniy,
I understand what you mean about Russia invading Ukraine. An awful situation. Hopefully Ukraine will prevail.


Do you have a photo of a hydraulic corrector? How easy it it to install? Any reference links?

Maybe for the 145 or 146 pump on my other engine if I can find all the parts to add a turbo to it.

[cherniy_chack]

Peter, all Bosch pumps installed on Transits before 2000 are equipped with a hydraulic corrector. It's also known as a smoke corrector.
Pumps numbered 144, 145, and 146 have a hydraulic corrector as standard equipment, installed at the factory.
Pump number 154 has a factory-installed turbo corrector or boost pressure corrector.

I received the Otosan 154 pump. Oddly the timing hole is missing. Is this an issue?

The photo on eBay has this timing hole. I was assured the pump is factory set at TDC.

It’s also missing the pulley chuck which I assume I’ll have to remove from the Bosch pump.

[Peterr]

Update:

So the seller’s tecnician explained that these pumps are factory set to TDC on 1st cylinder. There is no timing pin hole. This is a new version of 154 pump the timing is set up at the factory and a locking nut is placed on the side to keep the axel from moving during shipping and must be removed after installation, as the red box indicates the position of the bolt to remove below:




So far I’ve been really happy with the tecnical support I’m getting after purchasing. My questions are promptly answered by a tecnical person of knowledge.

These pumps come without a mounting plate and “L” bracket to fasten it to the side of the engine block. They intend that the three front bolts will hold it fast. Vibration issues? However they did say if that is an issue I can remove the plate and bracket from the Bosch and mount them. How well everything fits and runs is yet to be seen.

I will also have to drill and thread a hole on the air intake to place a tube for the LDA as my intake lacks this:



Hopefully the pulley chuck from the Bosch is easy to remove and fits properly on this new pump.
