Please come and have a look at my jeep (it will be in workshop) and comment what and all have to be done.

Suresh is telling about Free Wheeling Hubs which improved his steering. Full Float is related to Rear Axle. Its better to call him and get it clarified, i think its bouncing over your head now I am not adding my "So Called" Tech jargons to confuse you more. Man, i never thought one day i will be talking about axles. Jeep makes you learn more

Thanks

I am going to closely watch your upgrade since it is of interest to me. I hope you will post your upgrade experience here.

Dear Sharath,
I don't know the exact length details of the drive shafts. I have talked to Arka and he has confirmed that CL 500 set fits in the CJ3b which is similar to our CJ340. The number of splines is 19 teeth and it will not change

Oh, I was under the impression that CL500 rear axle came only in semi-floating version.

Sharath,
I was also thinking the same, But Arka confirmed that one model of CL 500 did have a full floating axle. Since he knows Jeeps as his palm, I believe him

CL500DI came with semi floating axle only. Commander 650DI and Commander 750DP came with full floating axles but 650DI was underslung and 750DP was overslung. It is easy to get confused. In full floating axles also, there are 2 types, flanged and unflanged.

Thank you sir, I must have heard it wrong when Arka told me and assumed that it was a model of CL500.

Hello,

What should I do to make the rear axles full floating in CJ 340. I am giving the Jeep to work on with Raju (Suresh's Contact) on this saturday. So just wanted to do this too.

[Samurai]

Basically you have to use a Army MM540 axle or Mahindra Pickup axle which came in full floating version. But they are wider axles, you need to understand the pros and cons before attempting that.

This topic has been widely discussed here: https://www.team-bhp.com/forum/4x4-o...les-cj340.html

All the best Baburaj, my 550 is currently with Raju for minor repairs.

Hi Suresh,

The Older CJ500D-101 Wheel Base the fore-runner to the CL650 was the model I had mentioned about the Kinds of FFRA.

It Shares the same track as the CJ3B.

Interestingly the LWBs had FFRA with the diff off-set either to the left or the right and the un-flanged axles could be swapped to either off-set, by switching them left to right and vice-versa.

1) Flanged - Differential is in the Center and Off-Set Left (Usually FJ460DS433 & NGCS Vehicles Bolero/Marshal/Savari)

2) Un-Flanged - Differential is Off-Set to the Left Side ;Off-Set to the Right & Differential is in the center.


Regards,

Arka

PS - I have done the conversion for atleast 7 CJ3B. to name a few.
1) Gaurev (Red CJ340)
2) Dr.Jones Prowler
3) Patrick CJ3B
4) Arka CJ3B

Dear Mr Behram Dhabhar,
One doubt. What is the steel used for the Hypiods, Gearbox gears and axles and the hardening process followed in Mahindra jeeps? Also are the hypoids lapped as a set or it is used straight after the generation process/ checking in the gleason tester?
Suresh

@ Suresh:


The gears, bevel gears used in the gearboxes for HMIL are made of OCF steel and machined directly to finish tolerances. BTW, OCF is Orbital Cold Forging process.
