a little torch 'attention' required



light lunch ..... coffee and Pam's GF Cappuccino cake .... yum



16 out of 0.55M sq



trimmed up ready to put away again

Pam had to have a play about with them ....



held on with bulldog clips .... for now
going to take a few hours fettling, before I can get them welded in situ .... and dare say the 'design' may well change before then !!

also need to get the gates painted too .... if a colour can ever be selected!!

right gentlemen ...... I am in need of your collective knowledge/experience .... (if there's anyone actually reading this!!) .... maybe best guesses.

tripped over this pic today ......



this is the valve that controls the 'Drema's throttle .. this ain't mine but is identical off another Hydrema.

I have five levels of 'volume ' ..... Idle 1000rpm, standby 1400 rpm, low 1800 rpm, medium 2000 rpm and high 2300 rpm, all button controlled.
she auto idles after 10 seconds inactivity and I pre-select what 'volume ' I need on start up (or at any time I like after that)

if you can't make it out on the pic ..top pipe is labelled L and the port below it is labelled P

I'm guessing the 'goldy' coloured bit next to L is a solenoid and there're 4 wires going into the other bit from the multi plug ... as far as I recall and can see here

Anyone ever seen one of these before, or got any ideas how it works ???? .... it basically varies the stroke of what must be a cylinder which pushes the throttle cable and opens the injector pump up to give it the beans

I surmise that P bleeds pressure as required, from the LS line, when it senses a demand for 'action'

(I'll have to see if I can see WTF it comes from on mine),which is in no where near as convenient a position, to examine (tucked down/under/beside the Deutz's sump),as this one is - hence grabbing the pic ....
but quite how much travel to give the throttle must be determined by those wires, which presumably are the four separate switches on the dash - SB, L, M & H

also guessing the 'goldy' coloured item is responsible for dumping said pressure for auto idle to occur ??
Some kind of proportional stepper solenoid perhaps?

If this ever goes wrong it's gonna get a cable - end of, but would be nice to know HTF it works and whether anyone has any idea WTF this 'valve' is called ???
plus of course how it functions

Game on fellas .......

rudely awoken at 7.30 by me phone this morning .... me drug delivery driver lost one day we'll have someone turn up who's actually been here before !!

so a slightly earlier start than usual (I am retired, after all ) ....When it had stopped precipitating, 'bout 10.30, had a lil' project to sort.
Clara's birthday Saturday coming, and we've not got her until Friday afternoon this week - unusually, so had some time to get this together for her.



had considered making one, but couldn't for the price of this .... and having the dry time to do it.
pretty good kit, but yer average Joe'd struggle getting it together, especially with some of the issues encountered and some pretty crap 'destructions' to follow

when I put it together it had captures for M10 bolts ... in the UK they'm a 17mm AF head.
Bolts in the swing kit were M10 with continental 16mm AF heads ....
guess what didn't happen in their capture holes ..... they weren't and just spun
Good job I had some M10 x 55s to replace 'em with
Seems odd with all the ISO sh1t that Euro M10s are 16mm AF heads, yet nuts are 17mm AF
... have a lot on the 'Drema that're 16/17mm combinations

hopefully it'll have the desired effect, when she next arrives ......




She loves the swings at the play area, next to her nursery school, down in the village .... one of her own ought to go down a storm - we hope
The baby seat's for little Shem, who'll be here, from Plymouth, this weekend, for her birthday, but have a.n.other std seat for when he's grown a bit

Gonna have to bungee him to the glider though, for now ... super glue might be a bit drastic

spent a few hours after, collecting bloody leaves and bits of tree, after all the bloody rain and winds, these last few days ........ forgot to pop the bonnet on't 'Drema for a hose suss though ......Manyana
