It's BIG, Yellow and digs holes! JCB 3CX Project 8 is joining the Tractor Shed
awemawson:
After MANY quite serious (*) distractions I got to water up the pressure washer this morning, and it's not good news I'm afraid. I do vaguely remember similar problems a year or two ago and thinking I'd have to tear the pump apart. The high pressure pump is leaking back into the water feed pipework and blowing it apart with quite dramatic results. I assume that there is one (or more) none return valves in the pump through which it draws it's feed and they should close as it pumps, but it (they) must be stuck open.
OK a job for the future and I'll have to find another way of de-greasing the JCB :bang:
(*Many Distractions: A friend was here having tea waiting for the time to collect toddler from playschool in Battle - a couple of miles away. Goes to car and starter solenoid just clicks. I trundle a huge tractor battery to it in a wheel barrow - still just clicks - getting dark, can't see the starter motor to thump it - time running out - OK I'll take you to collect child and worry about car when we return. While this is going on her husband rings to say that their Shire Horse mare is 'down' - this mare is 3 months from foaling. OK abandon car, take her and three kids home meanwhile husband trying to get vet. Dropped her off, still no VET, and she is arranging for Fire Brigade Fallen Stock Unit to try and raise the mare.
This morning I got the sad news that the mare (and of course foal) had to be put down - all rather depressing)
Spurry:
It seems that the more problems we have, there is always someone who has more...
awemawson:
That's certainly true Pete, sadly someone else is always having a worse time.
Still the RAC turned up to tow her car away today, and by one of those odd co-incidences he was a chap who rents storage space for his caravan here !
So this evening I proved that a hot air gun was able to soften the congealed grease on the JCB sufficiently for it to scrape off with a paint scraper, but this is not a practical method. Firstly it would take a month of Sundays, but also there is a danger of scraping the paint off as well.
. . . However it proves that a hot water pressure washer should work.
Next decision . . devote time to dismantling and hopefully fixing the Karcher MPDS or shove it back in storage and find another method . . . .suggestions on the back of an envelope please !

While possibly not the optimal outcome for you, a thread on repair and refurbishment of the pressure washer would be an interesting interlude to the refurbishment of the jcb...
Otherwise, did you try a spray on degreaser?
Or, depending on the location etc, can you feed hot water into the cold water washer? Nowhere near as hot but maybe sufficient?

awemawson:
You are right of course Russ !
I woke up this morning thinking I can't face working down on the floor (where the Karcher water valves are) on this rather cold blustery day with my head streaming with a cold (no NOT Covid - I tested last night!)
Then it struck me - let the JCB HELP with the Karcher steam cleaner repair - it has forks (although up until now I've not deployed them) so bung it on the forks and raise it to a convenient working height. Looking at it, it is possible that the valves I need to rectify are all 'screw in external' types.
. . . job done . . just needed to lubricate the bar that the forks slide on to be able to slide them into a narrow enough format, and numerous ups and downs in and out of the cab to get them level and an inch off the ground before sliding the Karcher onboard and lifting to a convenient working height.
I've leave it at that for now, and put the dismantling and hopefully repair in the 'rebirth' thread that already exists on the forum: here for new viewers!
