Finally got all the "pre-use" stuff taken care of on this new-to-me 135. Took it out to give it a shake-down ride and noticed that just riding along it will slip out 2nd, which seems to be THE most useful gear. I have done some searching on the internet, found very little info about this issue but what little I found doesn't sound good?

Hi,
This may well be the result of prolonged 'crashing' the gear lever into second gear and will require a major
dismantle to make the repair if a 'lead' has worn on the gears. When you engage second gear at a normal pressure
does it engage in the detent easily as if there is little in the way of a detent or can you feel a positive
'click' to hold the gear lever in place? If it is an easy engagement then it might be something as simple as a
broken spring underneath at at the front of the steering box assembly. There are detent bullets under the springs
which engage in the selector rod to hold it in gear. These bullets can be badly worn likewise the notch in the
selector rod. Add the last two together and the engagement and disengagement will feel very easy and may be free
enough to disengage itself. If you should find that this is the case it will be necessary to split the tractor at
the rear of the steering box to withdraw the selector rod/s.

Yesterday I tested the shifting and yes is does slip into 2nd gear easily, in fact it shifts into both 2nd & 3rd without the positive "lock-in" feel that 1st & reverse have. I have not noticed it slipping out of 3rd but I have only used 3rd a tiny amount. Hopefully it will just be some broken springs like you mentioned. How much of a pain is it to pull the steering column off?

It is quite straight forward. Remove the bonnet and instrument panel. The panel is not essential if you can lift the
whole assembly. Disconnect the drag links and remove the battery tray. The steering box can now be lifted clear to
reveal the three springs at the front. Take GREAT CARE that you do not knock the springs into the gear box. It is
easily done. Remove the springs as soon as you can. Using a long nose pliers or piece of wire with a 'noose' on the
end retrieve the bullet plungers. If the tips are rounded this will be part of the problem. You will need to assess
the amount of wear on the 2/3 rod to decide whether you go further.

Don't be fearful of it. The great abyss is sloped towards the drain plug. You can also use one of those telescoping magnetic pickup tools to fish around in the abyss. If all else fails the detents are about 3 bucks each.

The drain plugs should have a magnet on them also.
