Santosh,
What silencer bend are you referring to? Am sure the GC is already good enough. Now whats brewing??

the 2nd bend after the drop from manifold that runs along the GB Cross member - i have bent that place more than once and also once broken the last 1 feet of the pipe in the quarry trail. i really want to find a permanent solution via a snorkel but not just at the end - but from the engine head itself! sounds stupid but possible - thinking along the tractor exhaust lines, but slightly route it towards the a-pillar and heat shield it enough not to burn ones hands!!

Santosh,

Allow me to post the solution to your silencer woes.

Taking it up at the A pillar will be as bad as Hitlers gas chamber vans (carbon-monoxide).

I too had thought about the silencer below the chassis level..before finally doing it on the Lynx, take the exhaust in the shelter of the GB skid plate. I did a lot of off roading in Hyd and elsewhere in the Lynx with this set up and it never failed me.

Pics for you.

Regards,

Fazal, Nice S bend you got there, eliminates the 2 acute L bends at the face of the GB Crossmember

In the last 2foot section after the rear diff - I broke it over a bunch of rocks last year after Rebuild and nearly blew my head gasket as the broken part got crimped... i am seeing a good way to avoid it again. Regd the fumes - do you think even if I raise it a good half foot over the a-pillar and bend it outwards like the tractor, the issue of fumes will arise?

Edit - Fazal - I think the flexi hose is not water proof... I also wanted to avoid that bit - once you dip this setup into a stream and floor it - the whole system gets flushed!! At least happened in my case...

---------------

PS - At last my pending project is on its way... the right side one with the bigger pulley!

Santosh,

Oh yes ! the fumes will be sucked in especially when driving at higher speeds (see the Thar guys crying about the fumes in their rear cabin?) the vacuum created by air displacement sucks the fumes in the cabin.

Go for the rear set up as in my Lynx (refer to latest pics of the rear end, on the Lynx thread) you will notice that the lowest part of the finished tail pipe is lower than the chassis by just 2.4", enough to sail through all exit angles and boulders.

The flexi hose has been into deep water a couple of times, at AKC it was underwater for almost 5 continuous minutes, at times half the front grill was under water but I had no issues with water entering the exhaust system ever.

After a loooooong time - got approval for half a day 'private time with my jeep' - found time only to do this small mod. Got a tiny L pipe brazed onto the rear diff cover to act as the breather pipe...

Also, if you guys recall a talk earlier in this thread - in a SFRA there is a grease nipple for the sole' rear bearing. I tried to replace that with a bolt but in vain - did not get the same size bolt to permanently seal that opening which causes minor oil leak... so planning to dip the grease nipple in araldite or anabond and refix it in full torque!

SVS, bad idea, think of brazing than glueing.

no ways i am brazing anywhere directly on the axle housing - this grease nipple sits on the housing rather than some carrier plate alike - what is the issue in glue-tightening it up? We glued up the engine (oil pump bolt) itself in your case...

I think he means braze seal the nipple, and then screw it in.
But why don't you measure the thread. Most likely UNC/ UNF.

ok^ but that wont work either i guess - the leak afaik is not from the nipple opening - its from the thread itself - or could it? I am not sure... let me find a matching bolt from a authorized fasteners shop next week... it is i think a 1/4 inch size 12 spanner head bolt, deep/rough thread...

PS - sudarshan bhai - yes water over the years inside diff has caused rust on crown/diff cover, all over!!

If the grease nipple has a MM part #, order/ get one, and measure its thread. Or maybe one of the gurus can help.

Default PTO Aircompressor Complete

PTO Put to use - got a small air compressor and spent a day to make it work - this is 1st cut of work - pending work is rounding off rough edges in tub, servicing the compressor's crankcase, and adjusting the belt tension...

next work is fixing the mini air tank and getting a length of air hose and air nipple to fill air in tyre...

Santhosh,

Nice job done. I'm glad you have made the first PTO equipment that is not a winch to use in any known Indian Jeep. Congratulations.

My hands are tied, there are lots of projects pending back in India for me.

I'm ignorant I really didn't know that Jeep borewell machines are out there, personally I haven't seen one. Could you post some pics of those Indian jeeps with locally fabricated PTO mechanism?
