Default '59 CJ3B with XDP 4.90: Mechanical lessons underway - Phase 1

Alright, a few pictures to start this thread and gather some eyeballs.













Now that I've satisfied your eyes, its time to pry open the brains. My jeep has been in hibernation for the past...year. Now, I have sent her into the garage to have her looked into and change what I think is necessary to get her back on the road again. BTW, her nick's Free Willy.

1. Engine - The problem
- I noticed white smoke during early morning starts. It would burn my eyes. Plus the early morning starts would also take hell of a lot of time.

What could be the possible issues?
- One issue could obviously be with the starter for the late starting. Opened her up, and there you go - the bendix was warped and had to be replaced.
- The second issue for the late start could also be the glow plugs. But they looked fine.

- White smoke/burning eyes. A very dear friend suggested I sit in a closed garage/room with the engine running and figure out what the problem was.
- There was not a huge loss in power or compression as such.
- So I zeroed it down to maybe injector issues.
- Opened the fuel pump, and horror of horrors, there was a lot of dirt and mud in there. My mechanic (a lead from Suresh) straightaway consigned it to the bin.
- We then opened up the fuel tank (which is placed underneath the rear - horrible placement really). And yes, we found more dirt there.
- So obviously the pump was gone.

Now getting a reconditioned pump with a self styled *warranty* is working out to about 8k. Getting a brand new one is working out to be about 29k. Do I have any other options? I need the pump and the 4 nozzles.

Hopefully, the engine tamasha stops there.

More updates coming up.

Any updates? Try second hand pump if the new one costs too high

Default Fip

Hi Venkat,

The "SNAKE" is undergoing some heart troubles.

1) Service the Existing FIP.

2) Go for a post 2002 XD4.9P FIP (better revs and fueling)

3) Have got the Diff-Ratio's sorted out?

4) By now you should be bugging the daylights out of Suresh Stephen or JAMMY Anand.

Regards,

Arka

1. I am sending the existing FIP to a guy who specialises in this. Lets see what he says.

2. I have started looking for the XD4.9P used pumps. Thanks for the heads up on this.

3. The Diff ratios are sorted now. I am changing the front and the rear to 5.83 ratio.

4. I am also securing a 4+1 gear box and transfer case (double lever). With that ratio and a 3 spd, I'll probably be hammering the last few nails in her myself!

Hi Venkat,

5.38:1 (43/8) or 5.89:1 (47/8)

With 5.89:1 and 6.00X16 the world will go about its business all around you.

The KMT-90 will be a good upgrade.

Regards,

Arka

PS - Check your Diff-Ratio if it is 5.38 then let it be, if its 4.88 lower it to 5.38

In 1959 they still paid attention to detail. Nice aux lights up front with guards and indents in the front fenders. You have got to love it.

But what is this thing hanging on the back end?

I have asked a few friends and they replied variously:

Free Willy tongue depressor
Advertising space
Arka's cyborg mother
Hydrofoil for river fording

None of these answers inspire confidence.

Being a dentist myself i could'nt help but on Dirtydan's tongue depressor comment, good one. Am also waiting for the final verdict on what that actually is, possibly a contraption that was made to be like the nets that hunting jeeps used to have? or maybe even a fold out bench for sitting on when parked after a tiresome obstacle.

You're right on that one. Its actually a platform, on which you can stand and gaze out. I have had two fully grown male adults stand on this and ride with me for about 45 kms on the highway, and the stand held up without a whimper.

Ah, and I had about 8 people on board the jeep as well. All adults :-)

Were there any fowl, cattle, etc?? (just joking).

Reminds me of a Malayalam story opening like this:-

"He opened his eyes and gazed into the distant winding road. A huge ball of humans was coming down; somewhere in the middle of that ball was a jeep."

The story came in the Mathrubhumi dailiy, Sunday supplement several years ago. Anybody remembers the author?

Wow, u sure u got yourself just a normal Willys Jeep? or is it a state secret that its actually a Willys on Steroids? , anyways i seemed to guess that it was a fold out bench/platform because the hinges were a giveaway, but really did not expect that it would hold good for people to stand on it over a long journey
