Finally a big update. We got rid of the humming noise of the gear box. We swapped the gear box from a total loss 2012 T3 800. That car had major damages on right hand side, and upon verification with my SAs, it was declared that the GB is fit for use.
Many many thanks to shashi for hunting the GB as well as getting the work done in my absence. This is called petrol head brotherhood.
The car is finally noise free at speeds of even 100-110 Kmph. Only thing you can hear when you roll up the windows is the engine.
Big relief for me, as earlier whenever i drove on 4th gear for more than 50 kms, i got headache.
Since the engine and GB came out of the car, the painter in the workshop searched for all the areas which developed surface rust, sanded them and again re painted all the areas.
The GB mount was fairly new and in good condition, so we didn't change it. We changed the engine rear mount. All the oil seals of the new GB were changed and the old GB was cleaned with diesel. Also, the clutch plate, pressure plate, flywheel, release bearing were checked.
It was a gamble for us, because until the GB was installed in the car, there was no way to judge the condition of the GB. Once the GB was installed, shashi took the car for TD without bumpers, HL, grille.
He took an extended TD of about 30 Km and declared the GB fit. Once he came back from TD, the gear kit was changed (bushes on the gear shifter rod and the lever) to fix the play in the lever.
The gears now slotted very smoothly and without any abnormal noise.
The drive is much more relaxed and soothing now. I missed the organ transplant of my love, still i was relaxed because of the fact that there was someone who will take care of her as his own car. I haven't driven the car, so i request shashi to elaborate on the drive.
Thanks a lot buddy.
And, for a change, we also changed the front indicator lenses.
