Dear Santosh - see if you can get hold of Armada NGCS 4WD axles. If yes, swap them. Don't get into changing crown wheels and pinions, it never gets done properly. 5.38:1 will make a huge difference. With the torque of the XD3, this thing will become a mountain goat. Then you only have to lighten it and increase the approach and departure angles. Production Armada Grand runs 4.88:1. For manual shifter, use Thar CRDe parts. Floor panel is from same family.

Best regards,

Behram Dhabhar

Here is one link to a common axle wrap solution. It entails a hinged metal piece connecting the axle to the frame rail in such a way that it swings with articulation but holds the axle in place in relation to the spring pack(s). Note, a single piece is not recommended. Double or ladder is the ticket.

Axle Wrap Prevention

Dear Behram sir, nice to have you back!

I thought I already have the NGCS axles? Mine is a july/aug 1999 production model (reg in jan00). I confirmed NGCS after seeing the special bump-protection for front diff Vs oil sump. I have never seen such a chassis part anywhere else! And I still have the data plate on the diffs - 4.88!

PS - I have dropped the crown/pinion reduction to 4.27 and instead going to upsize tyres to 16" (from stock 15"). Too precious to alter the originality of this vehicle.

but again 5.38 would contradict the above statement of leaving the crown/pinion aside :( i wouldnt do it anyways!

Lighten? How? this thing weighs a TON! actually 1.7tons IIRC - too little place to reduce weight?!! Approach/dep angles no issues, but BOA is SAD, dont want to risk SPOA and loose everything!

yes it is 4.88. Manual shifter for BA10? Or Tcase? My Tcase issue is solved, got a simple product and discarded the electric shifter. The side mechanism of BA10 is not my cup of tea, awaiting to implode the GB one day and either go the KMT90 or NGT530 way, depending on $.

Speedo on AG has stopped working. I think the inner cable has cut/gone kaput.

Would the bolero's speedo cable fit? Or is it a hard to source spare? Any help is appreciated?

Speedo cable fixed. Had to return the 1st cable and the 2nd one works. Too many choices and shop guy didnt get a exact length match for the sample (cut one). A slightly shorter one (God knows which MM jeep's!!) works as of now.

New issue : Fan Belt!

A good mentor once said "do a DIY fix of the fan belt" for learning purposes. I am not even venturing near that idea! Brrrr... The procedure involves removing :

a) alt belt
b) Pwr steering belt
c) AC belt
.......... Then you reach the fan belt!!

Tomm 1st half of the day is set aside for this task + the steering column bush is KAPUT - causing a ~1MM shake in the steering wheel. I suspect this is the cause of a (long time issue since purchase) THUD feeling over bumpy roads. This issue led to discover the axle wrap but I didnt fix that yet, but I suspect the steer-column bush to be culprit. Lets see!

Also - the air-filter had a plastic De-resonator kinda attachment (like a prefilter), removed it while refilling AC Coolant Gas and now the growl of a XDP Series engine is BACK - loving that!

Steering Column bush changed, old one was a bearing type, changed to whole-rubber to save rust/wearout!

Fan belt changed, cleaned the grime off the timing cover/front of the engine while at it!

Hi Santosh,

Do you know whats the size of the belt? 1145?

Also, can you please confirm if it drives the fan (water pump) using the PS pump as slack adjuster?

Thanks,

Dhanush

P.S:- Sir, my mech and a small spare parts shop in Bathery didnt know how to source that plate on which pintle hook is fixed. Also, strangely, Thar/Thar Di/Major manuals dont have the part number , even though its shown in the manual. Tomorrow I'm going to Mysore gujri. Will update you.

belt - 10*1000 (at least thats what was there earlier)

IIRC - this fan belt is only connected from Crank TO WaterPump+Fan. Let me post a pic later on...

aha... confusion again!

Please confirm!

Also, just back from Mysore Gujri. No plate for your AG. :( . You might get it in chennai or mettupalayam or moovatupuza. IIRC, Army ones too do the job and are a bit wider to accommodate the additional electrical something.

Total of 4 belts in my AG

1st) Connecting Crank -> Waterpump/fan (with the tiny pulley on the block as a tensioner) (longest belt)

2nd) Pump/Fan -> Alternator (tiniest belt)

3rd) CRANK -> A/C

4th) CRANK -> PwrSteering

No confusion

Sutripto - NOTE - Timing cover, I guess , right?

Gurus -- Will the 'timing cover plate' of a XDP4.90 fit direct on a XD3P? I know stupid question, but please answer...

Probably not since the xdp4.0 has timing gears and the xd3P a timing chain.

Thx Jyobeb, awaiting the shipment

Will a later gen XD3P timing cover with a 'triangular access plate' to loosed the FIP Gear fit in this XD3P engine? I guess kind of yes...?

My AG came with the stock 215/75/R15 tyres on 15" RIMS. (for testing) I changed the rear to 16" RIMS and 235/70/R16 tyres. There is a slight improvement w.r.t 'drop' in revs, and higher top end speed thanks to extra circumference. The AG has gained about 1.3"~ in overall height of tyre which means ~.6" in GC (Am I right?)...

Now hoping this would +vely impact FE too.

After a week of testing, I am already looking fwd to changing the front to similar 16" RIMS.

Dear Santosh - why did you put a bush in the steering column? It is a retrograde step and steering effort will increase. I have never encountered wear of this bearing, however, new bearing should be available. XD3P engine is notorious for consuming belts, please be careful.

Best regards,

Behram Dhabhar
