hey, khan_sultan, Congrats on your new hardware .

any specific reason for trying out on the rear diff, and not the front diff ?

Getting the Locker is easy but the next challenge is getting the install done (especially for a Gypsy) in an 100% proper manner. There are not too many mechanics who would have done this on a Gypsy.

Initially I thought of getting the locker (and many other mechanical mods) install done by any one of the tuners listed in T-BHP site. However, it seems that no one is willing/enthusiastic to take this project up, so I have to do it myself and rely on M.A.S.S mechanics and other folks that I know.

Yesterday evening, I called up Lokesh from Suraksha Automobiles (Hosur Road) and told him that I wanted to get the 'locker' installed. Understandably, he didn't understand a word of what I said and wanted. He suggested that we meet and then discuss; so we setup a time for today morning @ 8.15 am to meet and I was there dot on time with the locker.

As Lokesh is running a bit late, few other supervisors come and want to see the locker. None of them can make head or tail out of it so I try explaining on what this is and what it will mean to the Gypsy post install. By the looks on their face, I can clearly see that no one has understood anything (either the concept or the rationale to put up a locker)

Lokesh joins us a couple of minutes later and after a general round of small talk/chit chat (Sanjay Agarwal's Gypsy/K-1000) we start talking about the locker.

Lokesh: has anyone done this before here?
Me: No. Not to my knowledge.
Lokesh: (Says nothing). Scratches his head.

I again do my spiel what I did few minutes ago and he is again scratching is head. I explain the install procedure to him and we go through the installation manual in detail. I ask him how comfortable are your mechanics with the rear differential of the Gypsy? Have they ripped apart and put back the differential of a Gypsy at least 2-3 times? To which he replies, oh many times! I say then no issues. That should be ok.

We settle on Saturday morning for the install. Lokesh has kept the installation manual with him to understand it better and go through it in detail (I have told him that if he loses it, he will be hanged).

Meanwhile, the locker is with me; begging me to put it where it belongs -- the rear diffs.

Nice writeup - Good story build up - Lets hope that you have a vehicle that does justice to your efforts!

Keep them coming!

The rear is generally preferred than the front. But i guess it should be possible on the front too!

How will this physically lock up? Will it be electrical(switch) or mechanical(gear lever in addition to what exists)?

Not being of the typical automotive background - ran a search on what exactly you guys were talking about - so just to share for all here is what a "automatic positive locking differential" means.

Powertrax 2410 - Lock Right Automatic Positive Locking Differential - JEGS

::4WD Systems - LOKKA Automatic Differential Locks::

and guys let me know if these post are OT or misdirect - I might edit and take em out.

BTW what else have you planned for the Gypsy Khan bhai!

Thanks Irfan. So far I was wondering where exactly this lock is going to sit. Now I can visualize with this picutre. Thanks again.

Hey Shahnawaz,

Have someone that has installed a locker in a Jeep do your install. Perhaps put up a post in Jeep Thrills, or contact Arka.

I would not let someone that has never done anything like this to experiment with your vehicle.

Regards,

Have you spoken to Psycho? Or FRK?
I would also strongly recommend sending the car over to Electra Performance in Chennai.
They specialise in doing one-off jobs and have done a few hundred one-off jobs and are very technical and professional. Speak to Krupesh Patel.

No, bad idea. Please note that forward wheels are used for steering the vehicle, front wheels turn in different speeds everytime you turn the steering. You will break the axle in no time. During Coorg OTR, Sudhir Kashyap had discussed this issue with some of us specifically saying LSD or any diff locker should not be used in the front. Same goes for Gurkha's front diff locks, don't ever lock it in hard ground and turn.

When it senses the difference in speed beyond a point, it locks the diff. Unlike LSD, this allows no slip after it locks. That is my understanding, but I am not sure how it unlocks. KS, please correct me if I am wrong.

Gaurav, I know what you mean and believe me, that's a concern for me. I must have read and downloaded 100's of pages on the install of lockright locker in various 4x4's. pictures with step by step instructions etc.

Have posted in jeep_thrills also about it. Let's see. I doubt that someone has installed 'lunch box' lockers in their 4x4 here in India yet and especially for a Gyspy(though technically there may be not much difference in a Gypsy install/Jeep install ).

Reading the various material available on the net, it seems that this could be a DIY job also provided one has the right set of tools. But I could sense some unease when the install procedure mentions about marking some parts of the existing diff and remembering which part was from where and which sequence.

Keeping my fingers crossed

Have sent a PM to Psycho, however it seems that he is very busy. Let's see if he reverts back. Personally I would be more willing to let a tuner known in t-bhp work on the locker install.

Good idea but too late . Could have been possible that I attended the Palar first and then got the locker install done in Chennai and then again some off-roading and then back to Bangalore .

Probably Amit is keeping him so busy with his baleno. Just try to PM Amit too and see if you can reach Physco through some means. PM me if you need his number.

Somehow, the knee-jerk reaction on this forum, for any technical issue is to contact your local tuner. While some of these guys may know more than the average ustaad-mechanic, some are more of sales/marketing B.S. experts than technical experts.

But if you do have a tuner do the job, they should do if free of cost for you, since they will learn, and be able to offer the service to future customers.

A locker install is D.I.Y., if you have experience with gear install, like a ring and pinion, etc. Personally I would not advise it, unless you have someone with this type of experience working with you.

And by the way, you might want to get a couple of spare axles ready prior to any hard core off roading with your new locker. Just in case.

Shahnawaz I wouldn't be surprised if the web has some forums where this install on Suzuki Samurai's has been discussed in detail, and the mistakes during install highlighted. Do check that out too.

Pardon my ignorance.
I always think of Samurai as TVS Suzuki's

Sorry again.
