Thx.. Jaggu, not at all OT. would love to, but my mech has no idea of a hurricane and it is very delicate/risky to be fiddled around without knowing about it. But the GB - yes, try to drive catchkumars jeep now and get a feel of the GB, it is slicker than his DDIS's..!!

All,
There are two types of clutch system in general. The older/extinct 'Coil Spring' clutch and the latest AKA 'Diaphragm' type clutch.
Diaphragm Type - Coil-Spring Type -
All new gen vehicles come with a diap type for its many PLUS points over the coil spring type. For 1, the coil-spring is a VERY HEAVY type clutch, needs quite an effort over the diap type and had led to many a problem like below....

Having met Sutripto, I can now relate how tough the clutch should be to cause his discomfort.
BUT - there are a few obvious MERITS of a Coil Spring over a Diaph type. I may sound like I am harping - but - it is again the serviceability and cost of REPAIR of the system...!!
Yes, for many vehicle owners here, 'clutch' and 'repair' are OXYMORON'S, well actually the people who change the WHOLE clutch kit are made more of a moron by the manufacturer.
Any clutch system consists of the loading plate (Pressure plate) and the Friction plate (the disc with the lining material). The coil spring clutch is fondly called the 'finger type' clutch because of its 3 (in jeep) fingers that are actuated by the release bearing and it pushes the pressure plate onto the clutch disc and thus deactivating the engine power to the GB.
Now, there are many places any clutch system fails over a period of time. I am going to take a example of the fingers - they are available as a KIT and there are many clutch repair/overhaul shops/vendors who charge a nominal labor cost and the kit @ Actual and repair the 'coil spring' type.
For example, the 3 fingers + labor costs 400Rs and little bit of lathe/facing the pressure plate side will bring the clutch loading plate into life.
And, now the clutch disc. A MSL (Mahindra Spicer Limited) clutch plate or a LuK branded clutch disc is around 1600Rs for a brand new piece.
The clutch disc looks like this.
There are many components, but the main one are the base disc and the friction disc.
Base - Friction plate -
Now, the same vendor who reworks the pressure/loading plate, can work a clutch disc also. There are 2 critical parameters that need to be checked. The Rivet Quality and the friction disc authenticity. Kits are sold by clutch companies and used to repair all types of busted/in repair condition clutches.
---------------------------
In this case, Kumars jeep had the old type coil spring clutch which gave ALL SYMPTOMS of a FAILED clutch and needed a sure shot replacement. We sat thru the removal and were bracing ourselves for a 4000Rs spend on new and complete clutch kit. Clutch pedal needed to be released almost complete to engage the clutch and we had little hope. But, upon inspection we realized only the finger was busted due to a slightly smaller release bearing being used and it had eaten up the fingers altogether. New finger kit was 400Rs inclusive of labor.
Next the clutch plate showed signs of burn marks. Not due to lack of SPF45, but clutch fading and excessive clutch riding - which was needed due to above para (worn out fingers).
We could have just done a relining of this disc, but we found out the center spindle of the disc had some slight play and would lead to jerky starts, so ditched that idea, and exchanged this disc for a rebuild/relined disc with brand new lining and a proper spring/spindle setup - 600Rs.
For 1000Rs we now have a coil spring system which would make Sutripto smile, i am not kidding, it is butter smooth and does not feel hard at all. Did a mini OTR and no sings of fade/slip etc.
Kumar, please post all the clutch rebuild pics now. We were awaiting the results so as to not mislead new guys who want to save some $ by trying this idea.
