Lower Lowrange using stock gears

So with the gears on the manual shift case out I did some teeth counting and compared low range ratios.

Standard Transfer on a BJ42:
Input: 32,
Hi speed side of idler:43,
low speed side of idler: 26,
hi output gear: 32,
low output gear: 38
(43/32)X(38/26)
1.34375×1.461538 = 1.96

Low range ratio of 1.96

HJ61 Transfer:
Input: 32,
Hi speed side of idler:43,
low speed side of idler: 24,
hi output gear: 32,
low output gear: 41.
(43/32)x(41/24)
1.34375×1.708333333333333 = 2.295

Low range ratio of 2.295

Which translate to Crawl ratio of :

4.9 (H55F 1st) X 1.9 (low range) X 4.11 (diff gear) = 38.26 crawl BJ42 5 spd NA spec
4.9 (H55F 1st) X 2.29 (low range) X 4.11 (diff gear) = 46.11 crawl HJ60 Auto Transfer gears

And if I get the 4.56 diff gears I’m planning on down the line..
4.9 (H55F 1st) X 2.29 (low range) X 4.56 (diff gear) = 51.16 crawl HJ60 Auto Transfer gears + 4.56 diffs.

Not quite the same as proper crawler gears but at least its better than stock with the 34″ tyres.

Glasshouse Mountains run

Went wheeling at Glasshouse today, bumped into Beno in his tidy lookin lux just after little red… One thing I discovered with the tyres is that while they perform well 12psi on a non-beadlocked rim is a bit of a big ask in a tight situation. Saying that I’m really glad I only broke the bead and not farked a brand new tyre…

Did little red but was driving down it, even that got the pucker factor up, some of those ledges are nastey, especially in a SWB.. we only nearly felt like we were gonna put it on its lid once a few steps from the bottom..

Anyway.. had a good day out with a few 80′s, lux and fresh 3wk old stock standard pootrol.

they say TSL’s but they should be LTB’s (and look like ltb’s..)

Front Bar diet

put the front bar on a diet this arvo due to constantly getting hooked up with the width of the front bar and sometimes even the hitch receiver would get caught up… getting the shits with it all I cut it down slightly, ensuring that some of the front wheels get some coverage.

that should be the end of it getting me hung up hopefully.

Tube Fenders and sliders

the front fenders have copped a hiding the last few times i’ve been out as i seem to have a tendency to put it on some extreme side angles, often folding in the bottom part of the fenders and caving in both sills… so i’ve had enough of that and am in the progress of making up some tube fenders/sliders that tie into some barwork over the rear wheels.

Today was mainly spent getting the tube bent up and in sections for each side. I also managed to get the tube fender bits trimmed and tac’d into place. theres still a heap to do but thought i’d post some progress pics.

Rear mountpoint for the slider. This ties into the chassis-body support under the drivers seat.

Turbo bits!

Found a turbo for sale on the forums for the right price and snapped it up..

PIC_0841
PIC_0842

It was pretty much a straight bolt in but I had to adjust the turbo adapter slight so it cleared the oil filter (only just).

The the finished result.

It seemed the dump pipe was a bit restrictive it was modified for better flow..

4WD Monthly DVD Shoot

well.. did the 2nd shoot with the 4wdAction camera crew on much nicer day than the first shoot..

went out the springs 4×4 park the first time and it was pouring down.. we did 1 track and Roothy ran into some issues with his transfer case at the top of a big hill.. after winching him out and the camera dude getting soaked as well as coming down with the flu we called it quits..

then we return there on monday with much better weather than before and watched roothy do a cooking segment.. The springs pie.. a version of shepards pie.. went down well.. had a few brews around the camp fire then hit the sack for an early start.

got up around 7am the next day to another gorgeous day and got into conquering the hill that stopped our progress the last time.. with that out of the way the rest of the day was spent driving around,, waiting for the camera crew to setup, drove thru some obstacles then wait for them to packup… pretty hard when you just want to wheel but it beat a day stuck in the office..

i managed to grab a few pics throughout the day but not many..
