Got next doors TR250 here at the moment for a few jobs, main one being changing the spool block, it is one with a early electric type not the danfoss. Hasn't been any trouble up to 6 months ago but then started getting intermittent and basically annoying, solenoids seemed hard got hold of and with potentially eight to give trouble we decided to change it, it was the most hateful thing to use when it was working anyway, pretty much on or off!! Decided against a cable set up as they would be long with a tight turn when they came in the cab, either would of had to have been four individual levers or a joystick and two separate ones for tele and 3rd service. Rigged up a servo type valve using a joystick off a Daewoo excavator, although more expensive at least the controls will be the same to use as before. The joystick fitted in the armrest quite nicely!!

Used a couple of solenoids valves to operate the boom and 3rd service, they just direct the low pressure oil direct to the spool block, they are on/off type but was this way before anyway.

He wanted a couple of secondhand tyres for it which couldn't seem to find anywhere, so next thing was he said was get four new ones. Tyre supplier was not keen to fit them at all, said it was just about impossible because of the single well type wheels. They had failed in the past and had to take the wheels to be done on a machine, seemed to forget to mention this when I enquired about tyres!!
Well they're not impossible but are they ever tough!!!! Getting the bead back out on the rim is as much bother as anything.
