CJ3B & CL340 CJ340 (Mechanical Differences & Similarities)

[DKG]

Another fact CJ3B lovers should note is that while it was originally offered as a option the 43/8 (5.38:1) differential is what goes well with the petrol and is ideal for offroad application. The standard unit had the 4.27:1 ratio unit. Apparently with diesel many cars got switched away from the 5.38

Apart from a little metal tag at a diff case bolt showing 43/8 I believe another way to tell what diff you have is to jackup the rear wheel, bring the air valve to 12 o'clock, mark the main drive shaft wrt pinion housing, rotate the wheel two revolutions and count the revolutions at the pinion. You should get 5.38 if that's what you have or 4.27 if you have the standard unit

The CJ3B fans recommend the 5.38 as an ideal match to the Hurricane. Some have addressed the lower speeds concern with a warn overdrive. Wonder if any of those drives made it to India. BTW the overdrive turns your gearbox into a six speeder from three

There's a very nice article explaining all this in detail at the CJ3B website

Guess where Mohammed went after Partition. He then became the Finance Minister.

Have a look here: Mahindra Corporate

This thread is going to get really confusing.

In 1967 Mahindra stretched the CJ3B by 10 inches making a "91" Wheel base JEEP. It was powered by the F4-134 Hurricane engine.

In 1974, Mahindra introduced the B275 International Harvester Co. Tractor engine on the CJ4A and called it the CJ500D.

By 1986, Mahindra designed the MM540 series which were essentially a CJ5 with Peugeot XDP 4.90 engine.

In 1999, Mahindra introduced the MDI3200 (B575) engine on the CJ500D and called it the CL500 & CL550.

In 2004 the MDI 3200TC was introduced on the CL550 which we know as the Mahindra MAJOR. This JEEP is still in production.

Now you can connect the missing links of CJ / CL 340 and Classic on this data.

In 1974, Mahindra introduced the B275 International Harvester Co. Tractor engine on the CJ4A and called it the CJ500D.

By 1986, Mahindra designed the MM540 series which were essentially a CJ5 with Peugeot XDP 4.90 engine.

By 1990 Mahindra introduced XDP 4.90 engine into SWB CJ340 with the same CJ3B differential ratio

In 1996 Mahindra introduced Mahindra Classic aka. CL340 DP - Classic with first power assisted disc breaks for Jeeps in India and the differential ratio of MM540 and XDP 4.90 engine. This Jeep was considered a fine tuned version of all SWB

In 1999, Mahindra introduced the MDI3200 (B575) engine on the CJ500D and called it the CL500 & CL550.

In 2004 the MDI 3200TC was introduced on the CL550 which we know as the Mahindra MAJOR. This JEEP is still in production.

If I am not mistaken, Mahindra had a Stretched 3B (CJ4A) with the hurricane engine as well. I am sure CJ500D was not the first 91 Wheelbase jeep from their stable. Were the CJ3B and CJ4A sold side by side from 1967 - 1974 ? When did the production of CJ3B with Hurricane engine stop ?

Someone please put some gyaan on this.

Those were for the Army, I think Mahindra produced CJ3Bs for the army till 90's. When did the production of CJ3B stop for Civilians ?

Which engine was fitted in the rare MM440,..was it not the hurricane petrol.
Arka's petrol CJ3B was a 1985 IIRC,..and this had the Hurrican petrol too.

Jammy Where art thou !!?

Wapedia - Wiki: Willys Hurricane engine

Willys stopped making it in 1971. Did Mahindra continue to make it under license?

Mahindra continued to make CJ3Bs for the Indian Army till 1990s as they had the license from Chrysler. Since Arka's and Harjeev's JEEP are army disposals, they have the hurricane engine. The question that we have now is "When did Mahindra stop manufacturing CJ3Bs for the CIVILIAN MARKET in india ???"

They made it for the Army till 90s, I am not sure about Civilian models. Behram Sir, Arka, Jammy we need your inputs on this.

Help please.

Hi Guys this thread has confused me.

I knew models MM 440,540,550 ,but never knew the differences in them. now what is this CJ3B & CL340 CJ340? are they different from MM 440,540,550 ?

What is the jeep used by COPs?

Am a lay man in this topic please explain in plain words rather that using sophisticated techie languages

I think that the ones used by the cops should be CL500's or also known as the Major!!!
And CJ3B, CL340 and CJ340 are SWB jeeps whereas the Mm440 (petrol) MM540 & MM550 are LWB!!!
No I am talking with my limited knowledge so other will have to verify what Ive written???



But I think that we have deviated from the basic topic of the thread here which was

What are the mechanical differences in the CJ/CL 340 and the CJ3B!!! Leaving aside the engine

And will the Mahindra Workshops or specifically Mahindra Company owned workshop will be able to overhaul/ service the CJ3B's as its possible that the mechanics who now working there might have never worked on petrol engines???

[joshguy]

thanks harjeev ,but am still confused

Engine - Made by M&M (Designed by Peugeot and licensed to M&M)
Gearbox - Who made this? What is KMT?
Transfer case - Who made this? dana, spice, dana-spicer, M&M, BorgWarner?

Edit -

The CJ3B Axles had the famous Dana/spicer axles right? Who made the axles on the CJ340? Are they same as the CJ3B ones? Or did M&M make new ones for a diesel engined SWB?
