  1. They should save as long as they are named differently. Saved tracks are limited to a maximum of 125 waypoints each on that model (which is practically useless).

    There are pluses to mapping units. You don't "need" to have store bought maps. Turning your track data into a map is fairly easy. I do that around here. All of the local 4WD tracks have been made into one small map that overlays onto other maps.

  2. I used a York from the junkyard. At least around here they are plentiful in many vehicles. $20 or so and it is in perfect condition. You don't need anything special. For the first year, I just hooked a hose directly up to it. I've since added a tank and a pressure switch, but they are not needed for filling tires.

    If you don't have room for a York, then any old AC compressor will do. Just add an oiler on the inlet or squirt some oil in before use.

  3. With all due respect to what has been said........this is not a race car.

    For this application, the worst case cooling duty is at slow speed and high power output when off road. The air flow must come from the fan in this case. All that is important is that the fan is big enough AND is pulling/pushing as effieciently as possible through the radiator. Many high horsepower rig run the rad in the back where little or no forced airflow is available (this keeps them from plugging with mud).

    Because the rads are sized for this low speed condition, they are way oversized for high power road use where much more airflow is available. If you do not believe me, compare a car rad of the same power level and you will see it is much smaller.

  4. Interesting that they don't list any body mods if you're running 235/85s with a 2" OME suspension lift?

    :blink:

    I think you are misreading somewhere. 235/85 will definitely need trimming, regardless of lift. The interference is front to rear, so a lift does not help.

  5. You need to trim. The best option with that size is aftermarket flares, IMO. With less backspacing (what you guys are calling offset :rolleyes: ), you would need MORE trimming.

    Note that the worst interference is at full articulation.

    Some more information here.

    I should add that spring lifts should not affect clearance....they sometime do....but they shouldn't as wheel travel should be controlled by the bumpstops and the shocks.

  6. I've got one - but its no use with the Bikini style winch mount as the pin fouls the mount and even if it didn't, you couldn't get the pin out anyway. Otherwise I would put it on.

    Agreed though - they do make a decent alternative - though they also bend in the middle if the towing vehicle gives it too much breakfast so are not 100%!

    I seem to think that Foley SV do a similar design but heavier duty replacement front bumper in the style of the military one with a central towing point, but I just looked on their website and I can't see it so maybe they have stopped doing it.

    I also found this while searching, looks interesting though a few £££

    Sorry, I thought we were talking about a cheap NON WINCH recovery choice. If you are mounting a winch, you can get a real bumper with preoper recovery point.

  7. But used with a bridle you can double those figures (which are swl for lifting).

    There may be better options but for a simple to fit and inexpensive solution I like them.

    A bridle does not double the ratings due to the bridle angles. Also it moves the pull point in so the inner sides are taking all the load. Any attachment that is under the vehicle is useless in most situations as you are normally burried when needing a pull.

  8. The problem is the bolt. It is a 10mm, 8.8 bolt in double shear. SWL is normally based on 20% of breaking strength. I'm estimating around 6400 kg to break the bolt in a perfect world. It really is too small for vehicle recovery.

    I never understand why people want to use them for that anyway. They are poorly placed and not really of the right level of strength.

  9. When I went wheeling with Yousef, in Colorado, he was running siped MTRs (sipes are very narrow cuts - the above tyre is grooved). He said there are tyre places in CO that will sipe them for a pretty reasonable price.

    In other countries you have to do them yourself. The tyre grooving tools like john showed use u-shaped blades. On many models you can flip the blade upside down and use it to sipe (2 cuts at a time).

    The tool I showed can sipe or groove. The blade turns over for siping.

    Professional siping machines mount the tire and have a powered blade. This sipes the tire fast. Unfortunately, it costs around $20 per tire and they will only do it if the tire is not used.

    So for the same price, you can have your own tool and do any pattern you want.

  10. Planetary style winches have in drum brakes. They are used the hardest with powering out under load. The brakes should disemgage when powering in.

    The Husky is a worm drive, no brakes.

    8274, external disc brake, spur gear drive.

    Milemarker, no brakes, relies on the hydraulics to limit speed.

    Planetraries:

    All Warn recreational winches other than the 8274

    Milemarker electric winches.

    All Superwinch electrics other than Husky

    Ramsey except RE series.

    Most other no name brand jobbies........

    Here is a sample parts view for a Warn XD9000, note where the brake is

  11. Only problem is - you didn't mention the temperature?
    The 'experiment' was done at 20c.

    :lol:

    Viscosities of the oils in question are on my site. VMX has a pour point of -32, MTF is -45. Redline MTL has the best viscosity range of any of the MTF fluids I have seen.

  12. I would be very suprised if mtf94 is actually 10-40 i wuld say it is alot thinner than that!! i have been playing with motul 300v which is a 3 ester fully synthetic oil 15/50 egine oil,so far it has been alot better i.e shift and noise plus temps are down a few '0c!!!!! indicating less friction.

    The Texaco MTF would technically be the same viscosity grade as a 0W30 motor oil and close to a 5W30.

    See here

  13. Really auto boxes have gears!!!!! come on really,sorry but i have seen more gearboxes than you have had hot dinners.Atf compared to real gear oil is carp,in the £48k wrc boxes i build we use pumps for lube aswell as for hydraulic purposes for controling diffs and activ roll control etc etc and we use 15/50 weight oil!!!!!!

    autos have gears doh???? really

    :lol:

    The story as I understand it (maybe Mr. Ashcroft can add details) is that the pump it not a very robust design and can be broken from the use of high viscosity lubes in cold weather.

    Trust me that the synchros are designed for the low viscosity. The gearbox will not shift in cold weather period with "real gear oil" as you put it. If you put in 75W-90 or similar have fun trying to shift below 10 C.

    There are lots of quality "gear oils" that have low viscosity and are designed specifically for manual transmissions.

    Here is a list of some.

  14. You can read it in his article about "nuance" of driving:

    I always did that when needed (steps).

    I'd be interested to know what you think about (just opinions/experiences,don't say "go buy an underdrive! please :rolleyes: )

    His problem is driving EFI V8s. The idle control forces the engine to push at a "high" rpm. A good diesel or carbed V8 doesn't have this problem, IME.

  15. The synchro are designed for a lower viscosity lubricant. In addition there is a pump inside the gearbox that is not designed for high viscosity lubes.

    MTF IS a real gear oil. So is ATF...... Auto gearboxes have gears too......

    Most modern manual gearboxes use low viscosity lubricants.
