so here are the answers.
1. my jeep stalls on the mechanical pump in about 30 kms, then i have to shift to the elec pump...reasons???
Not sure, and I leave this question to experts.
2. what is difference between piston ring job and overhauling the engine?
Basically, Piston ring job is that of remove the head and change only the piston rings without looking at any other point of the engine. They do this some times if the piston is worn out and cylinders and rest of the components such as connect rod and bearings are in good condition. However every time when they remove the head, the head gasket needs to be replaced. They don't even need to remove the engine from Jeep mounting to change the piston rings.
Complete engine over hauling is meant to be looking at every point of the engine and getting it serviced. So, the engine will be removed from the chassis and dismantled completed and serviced.
3. my jeep doesnt have a hand brake, does it work ina jeep? should i be haviong it? what is the approx cost involved?
Yes, Jeeps come with Handbrake aka. Emergency Brake. If yours is a CJ3B the hand break will be on the dashboard adjutant below the speedo meter. There will be a umbrella handle like stuff which is the hand break lever. The hand break works in CJ3B with a drum attached to the rear wheel propeller shaft, when you engage the handbrake the cable prevents the propeller shaft to run, hence braking the movements.
4. why do i have to press the accelator pedal and start the jeep , it doesn't start without it?
Since the Hurricane is not Multi Point Fuel Injection System (MPFI) as seen in the latest petrol engine, you need to give little acceleration when you crank the engine for feeding the cylinder with fuel for first compression.
5. the gear shift in reverse and 1st is much longer in comparison to the 3rd and 4th, is it normal?
Not really looked at it this way, may be some one else here will tell you.
6. how can i caliberate my speedometer , it shows excess speed kmph?
May be the gear which rotates the speedo cable in gearbox is worn out or Speedo meter itself having trouble. You can get a brand new speedo meter and get it installed. Check the rear of your speedo meter for the gear ratio of the speedo meter.
There may be false speed indication on the speedo meter if your jeep's tyre size is not standard or gearbox is upgraded and matching speedo meter or speedo meter gear is not replaced accordingly.
7. would front lambda hubs help in improving fe? and how?
Yes it is. If you look at the local city drive where you need to apply lots of clutch you may not see a major difference. But if you use the Free Wheeling hubs on a long drives you will easily see the difference around 2km extra milege for every liter of fuel.
Because when you use freewheeling hub you don't waste the engergy to rotate unwanted moving items such as front axle, propeller shaft and gears extra. Hence less friction, less motion load and less engery to move the jeep. so saving fuel.
8. how do i come to know that some thing is wrong with the carb?
There is no standard answer to this question, there may be many reasons for carb being wrong. You need to post a specific question if you have any issue with the performance of the jeep which can be related to the carb. Some common issues are
1. Engine temprature (Lean of Rich fuel supply)
2. Some color
3. Pickup loss
4. Leaking fuel
5. Flooding
9. are there any mechanical components we could get better in europe??(as i leave for a visit for there, and wanted to get a gift for my jeep ....)
I doubt, check
Mahindra Register • Index page which is a Mahindra Jeep club from UK and europe you will understand many of them having issues maintaining their jeeps as parts are very difficult to get over there.
Unless in USA many Willys components are direct fit and you will lifting kits, jacks, winches, overdrive and other PTO stuffs that are designed to work on a CJ3B I'm pretty sure now to tell you don't waste in looking for stuffs in UK and they are costly out there.
You may check if you want steering dampers and few other electrical items, but normally UK is considered high on price.
10. what precautions do i have to take after driving my jeep through serious mud and slush , also through water ? as in after an otr.
When you ask about sand I would say keep the momentum do never try to dig up you will losse tracktion leading to complete recovery need mode.
mud you need to careful on the speed and steering, some time I felt turing opposite direction makes you drive straight.
No much experience in slushy situations, may be some one else can help you.
Water crossing needs more precaution as any other mode, you really need to aware of your jeep's internal a bit. The limit or level of water restrictions on the jeep etc.
Important think aware of the air-filter inlet, water should never go through that whatever happens.
Secondly check the breather values of your differntials to be connected to a pipe and put it elevated place
every time when you do water crossing, immediately treat the jeep with new oil for differntials if it is mixed with water.
Check all the greasing points under then body for lubrication requirement
If you use paper element air-filter pay attention for water in it.
11. my jeep is a ex airforce jeep and has the spare tyre mounted on the left with the swivel contraption over the tail gate which falls down. i wanted to ask whee was the jerry can fitted on this version , if there was any? also where should i put it , as i need it and the right side of the tail gate is having the blackout lights and reverse lamp and other things. also what were the original format of markings on these jeeps?
You can mount the Jerry can on another swing open type door as you seen for your stepney on the right hand side. Other wise you can fit is on the right hand side before foot step behind the fender.
If you are using a Mahindra Jeep, then the marking will be on the grill and tail gate embossed.
If it is a Willys jeep, then Tailgate, Bonnet sides and Grill will show you the willys embosement.
12. i wish to fix in a ammo box to fit in some spares and other nick knacks, any idea of where it sould be as the space is already a constraint, we are usually 4 friends in the jeep.
Amo boxes are in 3 sizes, I'm planning to do the things on my jeep
a. The smaller one to go above right hand side above the rear wheel arch for First Aid Stuffs.
b. The medium one to go between front seats for some recovery stuffs such as DShackle etc.
c. Long one to go behind both the front passenter for all the tools, please note that since you are going to be 4 friends always, you may not be able to fix this one as it takes lots of space.
I hope my answers gives you a kind of overall answers to your questions in general.
