Boost sensing pump

[igotalake]

Hi all,

After having decided to replace my failed epic pump with a bosch i have come to a halt with a dodgy bosch pump which i bought second hand, no guarantee.
Anyway, i'm looking for a replacemnt 145 686 but in the meantime i was wondering how much the 'high lift camplate, large fuel head, boost sensing pump' that i have read of would cost if anyone can tell me.

Thanks,

John.

igotalake,Do you want to repair the injection pump?Replace the cam washer and the plunger pair?If I understand you correctly, the repair of the injection pump will cost more than checking and buying another injection pump.

No i don't want to repair the bosch pump that i have. I am looking for another pump.

I have read one or two posts mentioning a pump which has a "boost sensing top" which should in theory work better with a turbo than the plain bosch.
Question is do they really exist and how much are they?

Re: Performance mechanical pump for turbo 2.5 Di.

Several posts about it.

Basically you put the top half of a Landy pump with LDA set- up on to the bottom half of the Transit pump.

Set-up/tuning of the LDA is discussed on most Landrover and VW diesel sites, just bear in mind the cooking DI motor wasn't designed for boost controlled mechanical fueling in mind, so you will have to muck about with manifold bleed line restrictors/dampers to stop diaphram/torque piston flutter at certain Rpms.

Such a pump exists, its brand Bosch VE 0460 414 154.
I have such a pump, my friend gave it to me.
Another friend of mine says that such pumps were installed on TF for Turkey.
I recently installed it on the car.
The engine absolutely does not give smoke, but it pulls worse at low engine speeds.
Another friend of my friend installed on the injection pump Bosch 0 460 414 145 plunger pair with a diameter of 12 mm.
He claims that the motor has become more powerful and works gently.
He claims that his usual speed is about 150 km / h.
My speed is about 80 km / hour.
He's young, I'm old.

Thanks for the replies. I have pm'ed andypdq about his boost sensing pump.

Cherniy, is the 154 fitted to anything else other than turkish transits? I have looked and it is not cheap at 3 grand new. Nothing available on the second hand market.

I'm happy enough with 80 or 90 km/h but don't want my van to take 2 minutes to get to that speed.

Early UK TDs had the LDA Bosch pump.

In all honesty, the EPIC system is the best, the 100ps version is lovely to drive and quiet with it. Bosch convesions lose some of the civility, but do allow a bit of tweeking, all be it at the expense of some/a lot of smoke emmissions.

The 145 and 146 pumps are a reasonable match for the TD motor, and if you know what internal adjustments to make can give more stomp than the EPIC with very little extra smoke. They will smoke like a Chinese Grandfather if you give it a footfull before the turbo has had a chance to spool up though.

Bosch pump is the only sensible option for NA conversions.

No complaints about the epic pump when it was working. Started on the button, very smooth and powerful enough even towing a trailer. I wish there was a fix for the cam ring sensor fault.

I wish there was a fix for the cam ring sensor fault.

It can be removed, cleaned of steel sawdust, adhered to the magnet and set in place.
Before removing the rotor position sensor, its position must be fixed by outlining its contour with a needle.
Before reinstalling the sensor, replace the gasket.
Our people somewhere buy spare parts for injection pump EPIC, I have tried many times to find a seller-unsuccessful.
However, the Bosch injection pump can be adjusted to sufficient power with a small amount of smoke.
The main element with this setting is the screw under the lid on the pump fungus.
If the lid is no longer-it means there was an intervention in the pump settings.
But it does not matter.
The device in the form of a fungus on the cover of the fuel pump is called the "fuel pressure corrector" or "hydrocorrector."
Its purpose is to reduce the supply of fuel at high engine speeds, when the fuel pressure in the injection pump housing rises.
If you tighten the screw in the fungus, the fuel supply at low speed increases and the power and torque increase.
Together, by adjusting the supply of the common feed screw and the screw of the hydraulic corrector, you can get a quick acceleration of the machine and a small amount of smoke.

Oh, I was wrong!
Of course, this is the sensor position of the cam ring!

igotalake,here a little information about the EPIC system.

I doubt if you'll get a reply from Andy, he hasn't visited for a long time.

You're right Chuggy, no reply from Andy about the boost sensing pump.

Thanks for the info Cherniy, but i would love some detailed info on the epic pump as the LDV manual doesn't go into detail about the pump, it just concentrates on the fault diagnosis with the Laser 2000. According to Minormatt the problem is that the cam ring gets sticky and the fault is not necessarily the sensor itself.
