Sanderson 6-22 telehandler

[Johny Walker]

Not sure about engine options after 17 or more years. Nothing wrong with the Ford but I think 525's were Perkins; will have to have a look at my mates example when I'm there again. Artic. loader is good for forks type work or "craneage" as steering acts like carriage sideshift. Might not be so handy in tight yards as 4 wheel steer. I wouldn't say any telescopic of the types discussed would last in woods environment for long.

 

it going to be used in a yard stacking log & chip,kind off out grownn the 4x4 tractor so flog that & get a t/p

Thought that could be problem. Similarly I used to go to a market garden/nursery when they moved to a more modern tractor with starter interlocks; I more than once had to go to a tractor which wouldn't start with no reason to find that the rear of the cab behind the seat was stacked with coats and bags the result being the P.T.O. lever getting knocked into drive unnoticed and then when it came for the workgang to move on the tractor wouldn't start because starter was locked out. It was a most orderly place; the nominated tractor drivers had to have a whole day training course at the college and they had to fill in a most comprehensive daily vehicle checklist (tick all the boxes).

However on the Sanderson; the small rams at the rear of the mast compensate the forecarriage ; so the "bucket" or whatever attachment stays level (or tilted to about the same angle) as the mast goes up and down. The most likely reason for them to be disconnected is that they leak internally so the "bucket" continuously tends to droop on the crowd ram needing constant correction; which can be incredibly irritating (and very dangerous!).

To reseal the rams isn't that hard but the pistons are solid (don't split) to get the new seals on; we had I presume supplied by Sanderson some machined nylon-like rings (tapered one side to slip the seals up, with a thin skirt the other side to clear the piston diameter and guide the new seal over the piston ring grooves into their place; seals heated in kettleful of boiling water to soften) which were for fitting the seals, without which I think would make the job difficult without damaging the seals. Happy days; of course then you may have found that they also leak on the piston rod seals so then you have to get the piston off the rod to change them as well usually fixed to not come off; so they wont but occasionally have unscrewed themselves partly and only hanging on. However not all hydraulic rams can be serviced without special equipment in the "field" at all; which we often did including the big "main mast" lifting ram.

 

Cheers for your help Rustcutter, I'll have a look at those rams when I get time.

Hi not sure if anyone can help. I have an old 1989 Sanderson 6-22 telehandler which has stopped driving forward. It works fine in reverse however it takes a couple if seconds to move after the throttle is pushed down. Any help would be appreciated. Thank you

Is this one with a shuttle forward/reverse and therefore no clutch?  If so first thing is to check transmission fluid level.  If it is a fault with the drive I suspect it may need a good agricultural engineer. 

 

It is essentially robust Ford mechanics so should all be fixable, but machines like that are never cheap.  Still you have a fighting chance unlike newer machines.

Thanks yes it’s forward and reverse on a lever which is clutch less.  It’s been acting up for a while, when you press the accelerator, it would do nothing for a few seconds then it would move. Was not so bad once it warmed up but now it’s stopped moving forward all together. Thanks for your sdvice I will check the fluid levels.   Any more advice welcomed 

 

thank you

As above check the fluid if its the torque converter drive model with a borg warner  box, its basically half of an auto box. If it is there is also a filter in the shuttle box sump which may be clogged. The trouble with clogged is its likely to be from plate material, the good news is they share plates etc with other BW units like the one fitted in an old V12 jag and are really simple to rebuild. Its less than an hours work once its on the bench.

Mines has done forward and not backwards several times over the years but always been a dodgy connection. But this is on or off and won’t change with fluid temp so probably not the case for you but easy one to rule out.  Swap the spool connector round to try it. If it then goes forward you know it’s electrical and not mechanical. I replaced the forward/reverse switch with an old toggle to get by but got a new unit complete for about £200. It’s a doddle to replace. 

 

You our should see a dramatic improvement in hyd filters and oil change too so worth doing anyway the filters are cheap enough but it takes a fair bit of oil.
