On the weekend...

Last weekend,I went camping with my missus.
Had some trouble with the Mog jumping out of reverse when under
load.This does not happen when I am towing something in reverse
down hill however.I wonder if the linkage is out of adjustment?
ITs a 416 that was ex Army,with four forward gears,you can only
engage reverse in
low ratio.(apparantly thats normal for Military Mogs?)
Is non Hypoid EP80 the right stuff for the Gear box on this
wagon?

Hi Norsk,
First things first, the 4x4 gear box is very nice :)
Unfortunately the symptoms yours is showing are signs of a
gearbox out job, and a rebuild. You could look at the gear lever
rubber boot,as sometimes these can be tight and pull the lever
out of gear, or the detent for the gear lever could be warn.
Otherwise it's a case of just living with the box as it is.
It looks like an amazing area you were camping in by the way :)

The 4x4 box looks like a good option. You can get much quicker
reverse speeds than you can with the 6 speed.
Oil wise, SAE 80, 80w90 or 85w90 can be used. Just make sure
it's not a hypoid oil.
Edit... Reverse in low range only is pretty vital. The 6 speed
box can make about 12kph flat out in reverse, the 4x4 box in low
4th can do 30! You really don't want to be going that fast
backwards!

Thank you for your replies.I'm taking the inspection plate off
the Bottom of the Gear box today to have a look.

Good luck. Hopefully it will turn out to be something simple
(cheap!) to fix.

Just a thought......... I don't know if this applies to your mog
as well? On my 404 I had to remove the top plate to sort a
selector...... I made the big mistake of doing this on a
slightly uphill piece of ground.
Everything was fine until I came to put the selector plate back
on? I found that I could set up all the gears ready to receive
the selectors and as I put the plate in all the gears had slid
back because the nose was up!!
I eventually managed to jack up the back and get it level - but
how I wished I had thought of the slope problem first!!
Also 404 owners....... when I was a Mog virgin, I believed the
helmets on the internet that said if you remove the interlock on
the reverse lever - you can get reverse in high range too! The
pratt even gave a "how to" - believe me it is complete and utter
nonsense and if I can save just one person from all that work
for nothing - GOOD!
The reverse gear is only available through the low ratio shaft
and anyone who tells you different is full of ............!

I took the plate off the bottom and adjusted a nut on a rod on
the bottom of the Box.This gave me more "reverse gear" I simply
screwed in inwards,along the shaft.this moved the
forward/reverse lever further back.
The shaft is cross drilled and the nut castleted ,so if you go
past the factory hole for the split pin,you have to lock it with
another nut screwed ontop of it.
This has so far sorted my problem of it hoping out of
reverse.The larger gear felt a bit sharp on the edges,but I
think that was a result of the selector not picking it up
correctly.Its a simple fix,took longer for all the Oil to drain
than to do the job.

Just for information the 4by 4 gearbox is the same as 6 speed
it's the selector that's different I've swapped these and indeed
still have one in the garage. Military like them for getting out
of the shit and rail way companies for obvious reasons. I find
the 6 speed a bit slow sometimes.

Is there a way to remove the 1st/2nd lock on reverse in the 6
speed box? Even hitting the rev limiter (3000rpm on mine) in 2nd
the reverse is slow as hell. I could get out and crawl faster!
I can see why the army wouldn't like it. If anything went wrong
you'd be right up the creek by the time you'd got the thing
backed up or turned around.
