Hi All

Still trying to decide if its time to rebuild the g/box / T/case or if I can put it off a while longer.

The box shifts in / out all gears fine and does nothing wrong except some noise in 4th and loosing oil from GB to TC but has stopped now with bypass hose (which makes no sense as its up hill for the oil to return to the GB ! but maybe the hose some hoe stops any pressure build up so maybe the oil now does not even leave the GB ???)

I am trying to find out what if any other GB or TC components can completely fail and let you down out bush?

It seems the T/C input gear has a reputation for complete failure, so if I just put a kit through the TC for now with a Terrain Tamer long spline type input gear which should solve this risk, what else is know to completely fail?

I would add the genuine double lip seal also.

Also do the Terrain Tamer gears last as long as genuine?

"What can fail to leave you stuck"

Geoff, better get yourself a good tape measure so you can determine just how long that piece of string is.

Seriously mate, who knows without stripping it down and having a look.

Personally I can't see how 4th should be the gear that is producing the most noticeable noise since this is a straight through the main gearbox drive path whereas all other gears use the lay or countershaft together with whichever indirect ratio you have selected.
On those boxes the 5th overdrive was an add on rather than being incorporated on the main shaft like the later H150 series.

As far as the longevity of the Terrain Tamer gears goes, I have only had a reasonably long term association with one. A good mate fitted one to his '93 ute at from memory, around 200,000 k's. It was still going fine about 150,000 k's later when he sold it.

The cross over pipe has been a very common mod for a long time just make sure the oil level is correct. It was common for toyo gearboxes to get a whine in them my previous 40 ser 4 speed, 60 ser 4 speed and my 1986 HJ60 sahara 5 speed all had a small whine in their gearboxes especially if it's been doing a lot of towing it cost me over $3,000 to get a 5 speed box reconned back in the late 90's in the sahara the previous owners towed a big van around. So if it's nothing major wrong with it you could try filling up with new oil and find an oil additive that may help reduce the noise and I read in a 4WD mag yrs ago that if it's only a small whine and it's annoying you turn your radio up.

Ive been contemplating this myself...
but going from a 4spd in a hj47 to putting in a 5spd of which the 60series was my idea...
A chat to statewide gearboxes in melb... told me this is not going to happen.
parts dont exist...as he has 14 gearboxes out of 60series he cant get parts for...
and the later boxes were better than the earlier ones... but no good as you cant rebuild them anymore.
soo best advice was to chase down a hj75 5spd...plentiful parts and will be for a while yet...
brendan is quite friendly and very giving of his time...onthe phone...
soo thats where im going to get the 5spd overhauled

drive your gearbox into the ground
and if youve got some cash spare...
pick up a hj75 5spd
and rebuild it and have it sitting in your shed....ready when the 60series box goes

empty 6x4 trailer yes

The early 60 ser had 4 speed gearbox like my 1980 2H 60 ser then they went 5 speed. So if I read this correctly statewide said you can't rebuild a 60 ser 5 speed box any more well if that's what they told you that is the biggest load of cr*p. Try doing a search and you'll find countless amounts of people supplying kits to rebuilt 60 ser 5 speed gearboxes and transfer cases. Hell would have been long frozen over before you can't rebuild a 60 ser gearbox I would be very suspicious as to why you were told this or did you mis interpreted what they told you or did I read this incorrectly as mentioned.

All Four x 4 spares done my gearbox up in the late 90's before I left Newcastle and they have been around for quite a while. Also click on the link and scroll down the list you may be surprised as to how many parts for the 60 ser box and even the 40 ser match with the 75 makes the people you went to seem like they don't know what they're talking about you really need to get advice from elsewhere.

Just going by the pictures shown on those links, it appears that the kits only contain a bunch of bearings, seals and gaskets. As far as I could see no gears or shafts.
I'd be surprised if you couldn't source the bearings and seals from a bearing company and the gaskets you could make yourself, although there are a few mobs around that specialise in making gaskets and shims to order.
I wonder if the guy who said that parts were no longer available meant that major components (shafts, gears, synchro rings, etc) were no longer stocked by Toyota and maybe the after market suppliers were no longer stocking because of age and diminishing demand??????

The link for All Four X 4 which doesn't seem to have worked has the gears etc just one company that still supplies them try a google search on them for the listing of the parts they supply.http://www.allfourx4.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/allfourx4/Categories/New_Parts/Toyota_Landcruiser/60_Series/Gearbox__Transfer

Give him a call....than listening to some nutters on a forum.
the balance line on the filler plugs...
Is to keep oil in either.
and not run either dry....
On mine the seal between the gearbox and tranny is leaking
ive replaced the tranny seal out the back 4times...even speedy seal hasn't worked.
All breathers arent blockes
And still pushing oil out the back of the tranny

Nutters on the forum I think you'll find your so called gearbox specialist is the nutter he certainly pulled the wool over your eyes.
