Hello.

I've read a lot of posts and thought long and hard about whether or not I should do this...

ok, I did it.
Remove the lid from the ESP (presumably a device or container), and line everything inside with paper towels.
'Removed the quantity setting mechanism, carefully marking both the quantity setting mechanism and the ESP beforehand...'
'Took everything apart, examined how it's built... then reassembled it all.'

Okay, here's what's definitely happening.

The engine is very difficult to start when cold, and it stalls if you don't give it gas.
Performance from idle to 1500 RPM is equivalent to a tractor *g*.

after that, like the fire department.

Just a heads-up: I have a new turbo installed, including the manifold, and new gaskets, so everything should fit properly with the turbo.

How do I properly adjust the ESP now, or which driving mode should I use?

Best regards,
Michael.

What do the tensions indicate for the upper and lower limits?

Compare with the relevant article!

Regards,
Guste.

Previously, exactly one marking was placed on both the interlocking system and the ESP.


As far as the theory goes, in practice, there's always a margin of error of a few millimeters... and that can be more than crucial.

After cleaning the MSW (Multi-Spark Waste), my 1Z wouldn't start (it wasn't due to a lack of diesel in the fuel lines). However, after moving it just a few millimeters forward, backward, left, or right, the engine suddenly started and ran smoothly again.

I would loosen the screws a bit, shift the MSW slightly (minimally), and try again. However, be careful: As far as I remember, the technical article also mentions that, in the worst case, the motor might immediately start spinning at high speed, so a second person should be at the controls and be prepared to shut it down if necessary.

Hello... and good morning...

It actually starts almost normally at 5°C... however, I have to give it full throttle. It doesn't do anything at all with just idle speed.
If it's idling, it won't accept any throttle for 10-15 seconds.
He only starts to pick up speed gradually.
I'm going to try shifting the pump towards the timing belt.

'Do I see voltage on motor control unit 1-3, or what?'

I can't say for sure right now, but the voltage with the ignition on is 0.800 volts.
The idle speed was 900, and the voltage was around 1 volt.

I need to create a log file. What should I log?

Best regards,
Michael.

Hi.
The production rate needs to be increased, so the gearbox must be decoupled from the timing belt.
Best regards,
Dirk
