I have a '58 Dexta and after a steep learning curve, have the old girl running again, thanks in no small part to the infomation supplied by a number of members of this site. I have just split a Super Dexta in half to investigate a possible clutch problem as well as replacing gaskets & seals as the old girl leaks like a sieve. The leaks are in the usual places... front & rear crank seals, input shaft seals and so on. The Super Dexta is a '63 model I think. Can anyone tell Me if there are any differences in the parts for the Super & the straight Dexta's that I have? ( apart from the engine & injector pump & govenor )Is it imperative that I know the exact age of the Super Dexta when I order parts from either FNH or Bareco ? Input shaft seals & bearings & clutch friction plates & pilot & throw out bearings plus front & rear crank seals & gaskets are the main items I will be looking for at this stage. No doubt I'm not the only one that hates eargerly awaiting parts to arrive only to find on delivery that the bits dont fit. Anti-climax doesnt even begin to describe that feeling of having to wait another week before being able to get at the old girl again. ( referring to the tractor here gents...). Any advice appreciated as always.

Hi Paul
No help with your problem sorry, but was supprised to see a fellow australian.
Pitty we dont have the interest here as the US.
My dexta must have been made by the same people as yours as it seems to have the same leaks, the main one being between engine and clutch housing, must be the rear main seal.
With the experience you have is this a big job to do??

You are right there Oscar. I have a 1958 Dexta in NSW Australia just west of Newcastle. It looks like a bomb hit it at the moment. I've just had the rear axle bearings and seals replaced and have the front end off to rebuild the steering. My main aim is to get it fully functional and pleasant to use, not as a restoration project. I am scratching my head over the steering box at present.

The steering box can be repaired. Assuming you have the problem of excess play. Remove the steering box and dismantle it. The wear will more than likely be in the cams at the bottom of the column. I have successfully had these built up with weld and reground to fit the cam assembly. The problem seems to be caused by loss of oil from the sump at the bottom of the steering box. My advice to all dexta owners - Check the oil / Replace the oil seals.
PS The top bearing can be replaced but it is unlikely to be the main problem.------------------

Hey Lilacman, Good to hear from another Aussie.
The steering box is a piece of cake. You dont need to remove it from the tractor. Disassemble it from the top. Watch out when you get to the loose ballbearings in the cup at the top. Take the top housing off & your left with the steering rod poking out of the box.Once you've stripped everthing from around it, take off the left arm housing & then remove the two studs at about 7 & 8 o'clock ( as in the face of a clock )from the housing. This will allow you to remove the steering rod. Remove the right arm & clean out the box. Replace the two arm housing seals.Check the wear on the steering arms & the steering rod, dont build anything up yet. Use a bit of grease when you re-instal the arms. Now, when you took off the left arm housing, there were shims. The trick is to eliminate the shims until there is very little or no play in the steering turn. Dont go too tight as it may bind up. When you re-install the piece at the top that has the groove in it to take the ballbearings, put the top bearing cup on & reinstall the top retainer plate with two screws only. Now turn the steering & watch to see if the top bearing cup mooves up as you turn the steering. If it does, you need to shim this area until the cup doesn't move up. Make sure that your shim doesnt protrude above the face that the top retainer has to seat on. Alternatively you can buy a kit for the top end, it consists of the ballbearings & cups & the bit that has the groove in it ( that bit also has the thread inside it to go onto the steering rod . The price I was given for the kit was $167 !!!!. I shimmed the original & filled her up with oil & she is like new. Let Me know if I can explain anything further for you. It would pay to get yourself an I & T workshop manual. I found mine to be extremely useful when replacing all the seals that I did.Good luck & enjoy yourself. [/B][/QUOTE] IP: Logged |

The rear main seal is daunting if it's your first time. The replacement as such is no big deal. Getting to it & rejoining the tractor is best done following instructions from an I & T manual. I did just that & managed to do all the seals on my old girl. Let me know if I can be of any help.IP: Logged |

Paul,
I am not expert but I am sure that except for the parts relating to the cylinders (due to bore size difference), injector pump and the front panels all other parts are the same on the dexta, super dexta. I find the bare-co online catalogue is a real aid along with the Vapormatic online catalogue. The Vapormatic catalogue is in a way better as you can select the specific model and then easily check other applications.Regards,

Thanks Paul and Gerard for the detailed info on the steering box. Just what I needed.! I'll give that a go and post you on the success or otherwise.

Paul,
sorry I haven't spoken to you in a while, I have been sick and busy with work. Did you manage to get to the Caboolture historic Open day on the weekend? There was a petrol Dexta there. I think the significance would of been lost on most people. It didn't sound right though with the petrol engine.The address of three useful parts website that I use are: www.bareco.com.au/index.htm
www.vapormatic.com/Australia/shopcustadmin.asp
www.bepco.com.au Hope this helps,
