{"product_id":"maxitrak-ruby-stock-code-3394","title":"Maxitrak Ruby","description":"\u003cp align=\"left\"\u003eA complete and running \"Ruby\", lesser-known sibling to  Maxitrak's ubiquitous \"Dixie\" (I've got one of those in at the moment  as well). This one is an older engine, paintstakingly stripped and painted by  the previous owner only to discover on the first steaming that a) the paint  wasn't heatproof so the boiler went all horrible looking and b) it didn't go  very well.\u003c\/p\u003e  \u003cp align=\"left\"\u003eAt this point he threw in the towel and part-exchanged it for  the Great Western 14xx I had in a month or two back (which also had dreadful  paint, but went well).\u003c\/p\u003e  \u003cp align=\"left\"\u003eThe usual (indeed just about the only) thing that goes wrong  with Maxitrak engines is the grubscrews slackening off on the valve adjusting  collars. Easy to spot, the engine can't decide whether it wants to go backwards  or forwards, and lurches along half a revolution of the wheels at a time.  David's been into the valve chests, valves are in the right place but open late  in forward gear. This is a bit odd, as the return crank is pinned in place at  the factory - it means that the engine runs but is a bit choppy going forwards,  as if it's constantly on a short cutoff (although in fact it's lack of lead).\u003c\/p\u003e  \u003cp align=\"left\"\u003eEverything else looks sound, boiler is ok, feed by injector,  crosshead pump and hand pump, cylinders are gunmetal oiled by a displacement  lubricator, valve gear is by Mr Marshall.\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020229726549,"sku":"3394","price":1450.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3394-1.webp?v=1779912077","url":"https:\/\/stationroadsteam.com\/products\/maxitrak-ruby-stock-code-3394","provider":"Station Road Steam","version":"1.0","type":"link"}
