The P38 is my first 4wd. Other than the Cape york trip last year I'm not as experienced in "real" 4wding as many of my fellow forumites (= I don't regularly exercise a set of 32" muddies:D). I have never experienced lockers. "However" about a year ago I did put the rig over an obstacle course designed to demonstrate the supposedly superior advantages of the LC200:eek:
When my turn came I approached the course with the EAS at "Access" height :twisted: Stopped, selected LR and max EAS. UUUP it went in just a few seconds:eek: and proceeded to 'climb' over an extensive grid of wooden "electricity" poles laid with some cunning at various angles. I feathered the brake with gentle pressure, while applying slight accelerator.
I was amazed at the 4-Wheel traction control:o the rig just ambled over the lot, wheels askew at all angles and never exceeding more than 1200rpm. At times there were only 2 wheels in contact with the "ground" but all four were turning as they should! I will admit the LC200 (petrol) with its ability to set crawl speed at about 1km/hr looked impressive, but was no better in terms of getting the job done...I'm probably $60k in front at this stage!:p

Wow, a few q's there! I'll answer them as best I can!
First thing I guess, it's an Ashcroft air locker! It has the advantage of further positive engagement over the arb unit. Secondly, it will never leak air like arb units do due to different design. It's also physically stronger than the arb unit with a major price advantage ($900 to my door). I dealt directly with Ashcroft for the purchase.
Secondly, yes I do have 4 wheel traction control! I could have put this locker in either diff, I simply chose the rear so I could keep the steering advantage! It also seems that the p38 will happily move forward with a front wheel in the air, bit as soon as a rear wheel kicks up the forward momentum stops!
Third, I can provide photos and info on the air/switch setup if you like. I tapped into the air tank, off a tyre inflation line to be exact, which is isolatable for peace of mind! The air solenoid lives with the emergency fuel release mechanism in the back!
It's a job that I was not confident to tackle on my own (the air lines and switch I did), so I had the help of a mechanic mate for the install of the centre, but I'd happily do it solo next time!
Cheers

On the topic of using the brakes, I am not an expert, but one would imagine that braking would tell the abs to prevent lockup of a spinning wheel rather than promote pulse braking of a wheel that has lost traction under drive? I'm not too sure on that one!

Well done
A quick and easy demonstration for people that may be considering a locker,but haven't seen for themselves just how much difference they make over and above traction control.
And a good demonstration of how having one can help save our tracks from being carved up.

Top job mate :D A bit of advice id run your air line in some conduit or a outer cover of some sort to prevent the chance of you air line puncturing from rubbing on something:cool:

Apart from fitting all the ancillaries would you say fitting the main unit into the diff centre is a DIY effort with no previous experiance of dismantaling diffs. I have seen a couple of vids on youtube but dont understand the pre;load and how to measure it. Did you use new bearings or re-use the old?
I have been looking at the chinese copy ARB units which a couple of years back were being slagged off as crap. Time has passed and there are now good reviews ( apart from ARB themselves)
-
Nice add-on mate!! Love that video that shows how usefull a locker can be.
I may consider one in the future:cool:
-
nice, lockers always help. but you forgot to try what the owners manual tells you to do first. in layman's terms back up and boot it. :wasntme:
-
Ha ha, it does work! I've found that it shakes the beer up though! I would say it is a diy job for someone with good mechanical skills. Setting the pre-load can be advised on rave. Just make a mental note on how tight it was when you pulled it out. The Ashcroft locker comes supplied with new bearings, all you need to option is the p38 spacer ring ($30) in order to bolt your crownwheel up!

Nice job Keithy, love the vid.
You might find the position of the switch a bit awkward though as you right knee might accidentally knock it. I moved my locker switches in to the dash binnacle.
Cheers, Paul.
