Khan sir looking nice , yet to test it i guess . How is the ride quality compared to OE ones ? What about body roll ?

Tyres look puny now , how much did the kit cost you ?

Why Sir? Infact this vehicle can take much more abuse and you will be comfortable

FC will need to be done. That expires (15 years) in April of 2103.


How to rectify that? Someone did tell me that take injectors for calibration and check if all have the same pressure. Can Mr KRISHNAMURTHY also do that part?

If I put in new injectors will the problem go away of existing injectors can be calibrated and used. If new injectors have to be put in, what all other parts also need to be taken into consideration for replacement for ideal setup?
One can fit the entire pump with injectors onto the pressure checking machine and check the feedback too - Please try to oversee the checking calibration if possible.

Seriously, I understand your reasons for trying this and I wish you good luck with it. I will be watching this thread with interest.

Slightly off topic but I saw a blurb on TV a couple of months ago that Suzuki has started selling the Jimny in Red China. There is still a persistent rumor that Jimny will be sold in India by the end of 2013 or so. My question is twofold.

1.) What's the status of the Jimny in India NOW?

2.) Does Maruti voluntarily hold back releasing models so as to NOT compete too aggressively with Indian car makers and thereby raise the ire of Indian protectionist politicians and government big shots?

The ride is much much firmer now, handling lot better. However, being a SUV, a SWB one & now with lift, it will have body roll but nothing much to be worried about. I think the experience of driving spidey for long time comes in handy

Tyres are 32" as of now and no plans to go bigger here :-).

Surprisingly, the smoke has reduced a lot -- a combination of my driving style change + some service aspects on the vehicle in recent past. Driven like a NA diesel, (and not a petrol), it does not smoke.

However, I will be watching this closely and at some point, when I understand a bit more about diesels/pumps etc will try and get this to near perfect state.

Thanks Vikram. I will be getting to this pump/injector work in some time in future. Am on a learning curve here and slowly understanding diesels.

Got this rectified this weekend and the Coils are now as how they should have been. The tilt has gone & vehicle stance is a lot lot better.

While the lift kit was being installed last weekend, had noticed that the power steering unit boots were cracked and a leak had started. Ordered the parts (boots & oil seals/repair kit) and promptly they arrived a week later. Got the work done this weekend along with all the gear oil, TC oil, Diff Oil change, Power Steering fluid change.

Here are some pictures of the work in progress.

The steering unit. Was a pain to get this out & took along time. NOtice that the boots are cracked.

The place from where the steering unit was removed.

The unit with oil seals changed & new boots. Should hold good for a long time now.

While removing the steering unit, the skid plates had to be removed. These are made of metal & strengthened at necessary places. Seeing this you can notice how much thought has gone into the engineering of parts. It is a 2 piece plate that covers almost from the front of the vehicle to under the gear box.

Finally, got the side steps also removed & here is a picture of Prado as it looks today.

Also, must say am really happy at the professionalism & attitude of toyota service folks @ Nandi Toyota Bomanahalli. It's really a pleasure dealing with them.

Yes, please do monitor this and if you find the root cause and fix it, kindly do share the details. My Tucson didn't smoke much over last 4 years, but we remapped it recently, and I feel I am running a risk of higher smoke now. In my case, the turbo to intercooler pipe had a leak (it's welded for now, but it still may not be perfect). Also, the the air-intake hose (the very first one in the air path - that sucks the air from atmosphere) seems to be aged and one theory is that it may be constricting during heavy engine load no proof of this yet as we don't know how to test this). However, I am going to replace both - the hose and the pipe and then take it from there. I don't like smoke at all and though diesels tend to smoke under heavy load, I want mine to be as perfect as possible, so I am looking to learn from all the sources.

Thanks in advance.

Its good to know that Toyota will work on a 15 year old vehicle without wale nor whimper nor gnashing of teeth. That's amazing! Getting a compression test on a diesel motor can be a bit daunting because of the much higher compression of diesels but I would try to do this just for peace of mind about the health of the engine. I would also continually monitor the engine oil level for some weeks just to make sure it isn't burning oil. I would also take a good long look at my cooling system to make sure it isn't overheating and I might stress test it just a bit to that end...just my 2 rupees worth of advice.

Have a question to the experts.

I noticed that the transfer case of the Prado has an attachment -- a metal holder that contains a molded rubber beading kind of thing. Was wondering what it was, function etc and on searching found that it is a called the Dynamic Damper.

More searching on net showed that people have mentioned that if they don't have this, it causes vibrations, harshness etc. Also, this is a VERY expensive part. Costs around some 400 USD+. YES..!! Just for a piece of molded rubber.

Not able to figure out how it works and how it helps in Damping/reducing vibrations?

The picture below shows the Dynamic Damper (The arrows marked).

^^: The Old M800 [flat nose - first one] has a similar kind of engine mount. Try it.

They are made of a special rubber compound that absorb the frequency of vibrations generated by the engine - Whats why they are EXPENSIVE.

You could also try aftermarket mounts from the US aftermarket shops.

Go for PU ones if possible

Till the experts give their comments, I would like to chip in with the little understanding I have.

You are right, these are known by various names dynamic damper, tuner mass etc. Essentially,the functioning of all these are the same. To tell it in simple terms this component (a spring, mass, damper system in vibration lingo) reduces the vibrations resulting from low amplitude, high excitation frequencies.

That is the most simple explanation, anything further, I will need to bring in some fancy terms like elastomeric bearing, hysterisis, vibration isolation and transmissibility, which will be too much to handle I'm sure. Over to the experts.

BTW, do you have any plans with this part? How did this query arise - anxiousness to know or something else?

They are right.

400 USD, you must be joking. If provided with the right tools, Viji can make these for 400+ INR. For reference, a similar part on the Thar costs 514.29 INR (slightly bigger in size). Did you observe this part on the Thar when you did the test drive report?

Cool. Why is this not present in say a Gypsy? Do MM Jeeps have this?

Quote:

The damper in my vehicle is not broken/needs replacement. I wanted to know how it works/what it is for etc.

But don't you think PU will not absorb vibrations as much as rubber? I have seen PU body mounts and the vibrations/harshness through those are much more than rubber mounts

Thanks Spikey. While I get the theory part, how do they work -- can you explain in simple terms (Is it that since this is mounted to the driveline/transmission, hence all the vibrations in that can be routed to this damper) (like they say have lightening copper wire in building)

Quote:

No. No plans. Just curious to what it is, what it does and HOW

Not clear from the pics, khan_sultan , but it seems to be attached only to the tcase...I would have thought that the other end should be attached also to the chassis. Or, is it going to do the damping just by mass addition ?

That is a tuned mass damper and that is why it is so expensive. Trust me it is far from being a simple piece of molded rubber. I'm sure the weight of the rubber piece will be controlled within milligrams for it to function properly.

Quote:
A tuned mass damper, also known as a harmonic absorber, is a device mounted in structures to reduce the amplitude of mechanical vibrations. Their application can prevent discomfort, damage, or outright structural failure. They are frequently used in power transmission, automobiles, and buildings.
