Benford Dumper Gear Selection Issue

[Mjhdevelopments]

I have a Benford dumper 4000, when I select gear and go to pull off it pops out of gear, does anyone know what the problem might be?

Any ideas will be great.

Drop the oil out of the box and check condition and quantity is as expected? Replace with fresh oil and see if it alleviates the issue.

If not, it could be shift linkage is out of adjustment or it could be a more serious problem.

My guess would the ball at end of selector has worn.

Are you with Kehoe's in Wexford, then @nickirl ?

We're up the other end, but have bought stuff from them in the past, very good to deal with .

Is that a Spicer COM-T4-2012 gearbox @nickirl ?

If this is the Turner/Spicer box (aka Compact Plus family) then service manual here may help:

Your not holding it in gear as you drive along. As soon as you have fixed your dumper you can have a go at mine.

Are they supposed to have oil in these gearboxes. I thought all constuction plant worked without oil as the operators cannot find the dipsticks.

Was that box found in the first of the JCB 3CX's with the white cab?

no JCB never used spicer turner boxes.

no JCB never used spicer turner boxes.

JCB would’ve used their own ITL boxes in preference surely, no?

Was that the 4-speed powershift box? If so pretty certain it was the PS750 box made by ITL.

Sorry probably completely wrong. Four shifts on the floor (I think) and mechanical forward / reverse shuttle, apparently some of the Sanderson handlers used the same box?

yes and no, the T3 sandersons did use a very similar spicer turner box but there were a couple of key differences.
firstly the sanderson didn't have a option to bolt on a 4wd box, it didn't need it as they bolted a drop box to its main out put shaft and used the drop box to split the drive front to back.

the second key difference was the valves on the top, sanderson ones had electric valves on the top with no pressure modulation, Manitou started with a cable F/R with a pressure modulation and then progress to electric F/R but again still with pressure modulation so clutches didn't go in with a bang.
