There is nothing to calculate as far as the tacho is concerned - what you see is what it is.

The calibration is for something else, not the rpm.

It is the speedo gear Calibration.

All vehicles have it including 2 wheelers have it.

In older TM vehicles they had different ratios, based on the design of speedo gear. Thus if you had to change the speedometer you must know the ratio else, your ODO or speedo readings will not be correct.

In the case of Tacho on the 2.2 / Sierra - it is a electrical Tacho (w/o cable linkages) with input from the alternator. I am a little rusty as to how it works, will inform later on.
Most of 2 Wheelers having tacho have now switched over to electrical tacho (w/o cable linkages).

around 10 litres. I would recommend filling diesel as soon as or before you encounter this orange light.

Similar to Steeroid's beached whale experience (http://www.team-bhp.com/forum/236736-post96.html), I went up an incline to a bunk with very little fuel and stalled. The truck refused to start. Unlike Steeroid, I had the luxury of slowly rolling back down the incline, waiting for a while and restarting.

can the fuel pump be operated manually in case there is a need on the safari? should be, will enquire with the service guys tomorrow and update here.

i suffered this once on the bolero, within 1st month of purchase, there was a broken pipe and diesel was flowing out freely.. never realized it until an auto guy pointed out at a traffic signal.. immediately stopped but by the time the mahindra mobile service guys reached me, fuel levels had dropped considerably and i got to learn of manual fuel pumps.. still feel the chill thinking of it, diesel though not as spontaneous to catch fire as petrol, the what if always lingers in the mind.

yes TATA has given a balloon in the engine bay. its used if your beast has no fuel and fuel pump has taken in air. Its on the right hand side (when you are facing the car). One can squeeze the balloon and i believe that this helps (Though I have never have been unfortunate to try this).
Its also mentioned in the service manual.
Will try to post a pic soon

Yes, turbanman got to use it on his recent Goa trip, he got stalled looking for the pump and had to fetch 1 liter diesel and then use the pump before the safari could start. But his needle had reached almost empty before this happenned.

Harjeev, which page specify this usage, just for my info.

Default Dampener pulley replacement

After a check, Concorde has decided that the dampener pulley in my Safari need not be replaced. It seems my vehicle already carries the new design.

got my pulley changed at concorde, took almost the whole day. vehicle seems much better to drive, thanks to the clutch bleeding that they did free of cost. the pulley change is required for vehicles before feb it seems.

the cranking seems faster now, may be i am biased in my mind reading about it earlier.. lets' see.

about the fuel pump, the service guy showed me how to do that when air comes into the fuel lines.. 5-6 presses of the balloon should do the trick as per him. good to know about it, though do not plan to use it.. :-)

Did he tell you how to detect the "air in the lines" and then use the pump or you have to know beforehand that fuel is finished before you use the pump.

Anyways what's the exact sequence of it.

in normal condition, if you press the balloon, you can feel the liquid inside resisting, if that is not there then the air has taken over.. 5-6 squeezes should take the air out and the feel of the fuel should come back according to the service person i talked to.. provided there is still some fuel left somewhere, though i guess this condition is best avoided, the bottom of the tank would always contain some debris and those getting into the engine pass the filter somehow would not be a good thing.

good indication is needle down, fuel low light on and vehicle doesn't start and your battery is good/ cranking happening properly.

these are my versions only, anyone going to the service station can please clarify these points and update here for all of us.
