This guy used a wd7 in his build.

do it as well as you can,but learn to do it better
there was a.n.other supplier on Fleabay a while back, reasonably priced too, but can't find them tonight

Yes I have seen this build before . Shame with the effort that went into it that the cylinders weren’t mounted correctly , leading to them bending on use.

Wouldn't it be a shame to go to all this effort though and then fit such a key component from China which might be made of cheese? Id want to be pretty sure of the quality I think

Are there any uk suppliers at all ? Is it not a shout to make it all British (or at least European built ) if possible ? Just to show it CAN all be done here .

My current plan is to use an IMO slew drive, which is a German-made unit. Other attachment manufacturers commonly use these drives for tree shears and grapple saws, so they’re proven in similar applications.
RagnarTech in the US also use IMO slew drives in the tiltrotators they manufacture, which gives me some confidence in going down that route.

Having some further thoughts on slew motor placement.
Because I’m using a standard slew drive, the hydraulic motor will inevitably stick out the back of the unit by a fair amount. It’s not ideal from a clearance/protection point of view, but I’m not sure whether it will actually be a problem in practice — I haven’t used a tiltrotator before, so I’m unsure how the geometry works out with a bucket fitted, especially when curling the bucket into the ground.
At the moment I’m weighing up two options:
Also, motor-wise: I’m currently looking at an OMP-style motor ( fits the slew drive ),
A smaller more compact motor is an OMM-type motor but I cannot find one that’s suitable for 180 bar and roughly 50 L/min.
Any suggestions on the best approach would be appreciated.

At the moment I’m weighing up two options:
- Accept the rear overhang and build a decent guard around the motor/hoses
- Reposition the motor above the slew drive and transmit drive via an HTD belt or chain

try Whitehouse products ... if it exists they could advise

What's your thoughts on repositioning the hydraulic motor? @V8Druid
V8Druid

opens up several cans of worms using belts
could make a housing to mount in place of the motor to re-position it on and use a 1:1 gear set up or as you say have it facing the machine suitably HD guarded.. nothing to say it has to be perfectly orientated at 90 deg.s to the bucket/machine either - could be placed at an angle which best suited clearance and safety.

How much further out does the motor sit than the ram if mounted below it at the back? That’s how my Rototilts are constructed (with a solid guard as part of the casting below the motor).

I have tried this orientation, unfortunately it hangs out a good 140mm from the outside of the slew ring. I will just give it a go with it hanging out the back to begin with and see how it goes.

How far out is the ram at full offset?
I think you’d be better with the motor facing towards you (where you can see it) if that will still allow full crowd. It’ll soon get smashed off if poking out behind the back of the bucket (if I was driving it at least!
)

Facing forward would be the ideal orientation . Limiting factor would be the thumb fitted to the machine would cause a collision when crowding the bucket.How far out is the ram at full offset?

Thumbs and tiltrotators just don’t belong together

Having tried a few different orientations, I’ve now put together a rough model of an externally mounted drive.
The idea is to run a 50cc OMM motor (with a dual cross-line relief valve) as I’d need to limit pressure down from the machine’s ~180 bar. From what I’ve seen, this is the same displacement motor used on an Engcon EC02 and a Rototill RC1.

Drive concept
- Motor mounted externally (to reduce rear overhang / improve clearance)
- Drive transmitted using an HTD timing belt
- Taper-Lock pulleys on both shafts
- Sliding motor mount (adjust motor position for tension), or
- A separate tensioner/idler pulley

yes , we don’t want to be removing the thumb every time we want to fit the tiltrotator. Keeping it permanently installed is a part of the design requirement.

two 1:1 gears would be easiest IMHDO ... a belt is always going to be troublesome, keeping it tight
