Many thanks DE for the Newage details. I've submitted an online enquiry form with details of my alternator.
      In the meantime, I received excellent & prompt service from SLEEMAN & HAWKEN Ltd, when ordering the Air/Oil/Fuel Filters for my AC1 engine.
The Markon end bearing is a standard  product - - 6203-C-2HRS (17/40/12 mm). I was lucky to acquire one from a local Marine Engineers in Fraserburgh. Made by FAG. A nearby marine electrical engineers provided me with slip-ring brushes. They're for a Stuart-Turner motor & a wee bit oversize. They actually gave me 3 pairs, backsheesh, as its years since they serviced S - T stuff. So who am I to complain about a wee bit of careful filing & fine emery-cloth rubbing down.
      Haven't done much work on the engine/genny this last week or two - my workshop is dry but unheated, and we've had snow/ice/ & cold winds up here in the NE of Scotland for days & days.

                                                                Regards,  Dave

Hello Bob, many thanks for your reply. Right enough, I reckon its worth changing the bearing.
       I emailed Listers about spares, and they passed it on to Sleeman & Hawken Ltd, from Teighmouth, Devon. They emailed me yesterday & said they held AC1 spares, and are Lister/Petter's UK parts agent. I've enquired about Oil, Air & Fuel filters, and also asked them if they hold Markon spares. I'll let folk ken as soon as I hear back.

                                         Regards,  David

Yep, another AC1 query from a Forum newby.
       This AC1 Genny on it's pram wheeled frame, was originally(20 years ago) used on a pal's farm as a standby genny. I wired it up via a Memrex mains change over switch. About 10 years back, my son acquired it for his wee croft, but left it mobile. He now wants it "done up" by dad. Covered in barn crud & dust & jolly rusty. Engine will need a full service - air & oil filters changed, engine flushed & new oil. Rusty interior of fuel tank needs thoroughly cleaning. The usual story.
        Securing wee bolts on black plastic alt. end cover - rusted solid - - so took a chance at stator casing removal without removing slip-ring brushes. Came off easy enough, but sod's law - one brush broken. Can these brushes still be acquired ? The Markon brush assembly(19-033C/1/E) was covered in crud & the 4 wee nuts & bolts heavily rusted. But have managed to remove it & clean up. Have tested the components on the wee pcb - OK at 2 x 0.1mF, & 100 ohm. So hopefully that(rocking-horse manure ?) wont need replacing.
        Just one bearing at the slip-ring end of the Rotor - guessing "fully sealed" - would folk recommend changing it ? Or are they r/h manure also ? It seems free-running enough.
        Any help & advice most appreciated.
