Default 10,000kms update

Hi all

I have completed 10,000kms on the diesel engine. The engine is running well and the vehicle is performing well on OTRs.

I had to get the following done:
  1. Change to a larger radiator as the engine used to overheat in 4L in summer OTRs (INR 3K)
  2. Get the fuel pump reconditioned as there was power loss when climbing steep slopes in the last few months (INR 4.5K)
Since the fuel pump re-work I had not attended any OTR till the NCR OTR on 1st Nov when the power surge not only surprised a few Mods but also suprised me. I am very happy with the engine performance now.

The problem I face now is mainly loss of traction, although since I have changed my HT radials for F78 this issue has improved vastly. Since the trails here can be very steep, sandy and bumpy (all at the same time!!!) it gets tricky keep traction. I am planning on installing auto-lockers on the rear diff. Any suggestions regading this would be very helpful.

Also, I have asked about MT tyres (non-directional) on the tyres and rims thread. Any suggestions there would also be very useful.

Thanks
Ankit

Can I please have some advise regarding installing Auto-locking diff on the front as well. i guess it will have to be with FWH for road use which can then be locked for off-road use.

All advise will be most helpful.

thanks
Ankit

Dear Ankit,

I won't recommend you to install a locker in front. When you are on trail, and FWH is locked, your front axles will have lot of strain with lockers engaged. And there is possibility for axle wind-up or breakage. Instead, install the locker in rear and go for LSD upfront. And make sure you have FWH installed. Refer the last page of Khan's Locker thread, you will get the part number you are looking for Locker. For LSD, you can go for Auburn Gear. No one tried this combo except Arka on his Jeep. As per him, it's like "Aim and Drive" and she will clear almost any challenges without any fuss.

Thanks

Thanks for your Advise sreerajunnithan!

Did a bit of research on the types of Mud terrain tyres I can use. The following tyres are available in Delhi as I have seen them on NIOC jeeps. Just need to find the correct size i.e. 215/75 or 235/75 R15s.

Any feedback on these would be very helpful.

Tyres in pictures from left to right and then down:
Pic 1 - BFG MTKM2 size 235/75 R15
Pic 2 - BFG MTKM size 215/75 R15
Pic 3 - Kumho LK71 size 235/75 R15
Pic 4 - Maxis Buckshot size 235/75 R15
Pic 5 - Bridgestone Duellet MT size 9.5 R15 (?? what size is this)

Ankit,

On stock gypsy rims, you can fit at the max 215 75 R 15. Go for yokohoma AT/S. or Michelene. Maxxis is the MT and it requires alloys since they come with minimum of 235. BF Goodrich is a good tyre, but will be too bumpy as it is hard compound.

Dwarak sir, IIRC, Mukunda has 255/75/15 on his stcok rims. Even I was running 235 Maxxis on my stock rims for some time. I think 235's on stock rims would not be any issue.

Oh! Does it not touch the wall while turning? Or spacer was used?

With stock rims, the oversize tyres will increase the height of the vehicle right? else, gets spreads across the rim on alloys.

Has anyone tried the FIAT UNO/PALIO 1.9D on a gypsy? Think it will be a good match for OTRs

Hi Shanawaz

Did the 235 touch during turning or Articulation? I have got 1 extra leaf on all four springs. I am planning to mount the tyres on stock rims as no more budget for alloys!

Trying to source the 215 Mud terrain BFG as well.

Will post my findings.

Cheers
Ankit

GoSlow, I guess you missed out to write the bigining digit of the tyre size.. i.e it should be 31x9.5 R 15 or 29x9.5R15 or something.. Pls reconfirm if this is the only no. written on it.

Hi Ankit,
I have been using BFG MTKM size 215/75 R15 for a year now, i would suggets you to go for this tyre because we have driven it around 20,000 kms in Mud, Dirt, Highway, Jungles, mining roads etc. Its performing well without a signle puncture over a year. I sourced it from Allahabad.

Regards,
Shubhendra Singh

Shubhendra Sir

Thanks for your inptus. I myself am more keen on the BFG MTKM size 215/75 R15. I have a friend who work in Michelin and should be able to source these for me. He is curretly travelling abroad on official business hence I cant get in touch with him.

Can you pls tell me which dealer in Allahabad and at what price? My wife is from Allahabad so I can try and get it from there too.

Cheers
Ankit

235 DO touch (like a mm or so) on full lock and during articulation it is dependent on the suspension setup.

I would suggest 215 as the optimum size. BEST SIZE IMHO for all needs -- daily drive + OTR's

any size bigger than this will require some changes in order to avoid tyres rubbing on lock-to-lock and articulation and going over bumps when turning.

Ankit,

my friend in Gurgaon has a Michelin dealership. Here's the price list of BFG (its dated, so not sure about the latest price). Let me know if you want any help sourcing them.
