{"product_id":"3-inch-scale-burrell-agricultural-engine-stock-code-12047","title":"3 inch scale Burrell agricultural engine","description":"A 3 inch scale Burrell 6nhp agricultural engine to the Plastow design, this one has come to us from a long time customer, now in his ninth decade and clearing out some of the larger toys from his collection.\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    An older engine, it was rallied regularly up until the start of COVID, since when it's been stored in the owner's dining room.\u003c\/p\u003e\u003cp\u003e    The boiler had a preliminary hydraulic test on arrival. Amateur built, it has several stay heads that showed beads of water, although nothing that concerned us enough to prevent steaming it - as expected, they were dry under steam. Firebox crown has more stays than called for in the design - untidily fitted, although dry under test.\u003c\/p\u003e\u003cp\u003e    The engine itself runs very well - missing its regulator and gland when it arrived, we've made and fitted one of our graphite PTFE regulators, which is light to operate and leak free.\u003c\/p\u003e\u003cp\u003e    In steam the mechanical pump worked fine, the injector didn't - clogged with limescale when it arrived, it's been cleaned out but needs replacement.\u003c\/p\u003e\u003cp\u003e    The mechanical lubricator doesn't work when the engine's running in reverse - curiously it's connected to the expansion link rather than the valve rod as shown in the design. Driving a lubricator from the expansion link is a great idea where the link has a fixed pivot (as in Walschaerts gear - it's how we drive the lubricators on the engines we build ourselves) but not so good where the link moves, as in Stephensons.\u003c\/p\u003e\u003cp\u003e    The engine runs on rubber tyres - the front nearside coming adrift, it needs some adhesive - which makes it quieter on the road, whilst slightly raising the gearing.\u003c\/p\u003e\u003cp\u003e    \u003cbr\u003e    \u003ciframe width=\"353\" height=\"198\" src=\"https:\/\/www.youtube.com\/embed\/MR2trvSCB_I?si=AN-8_MAqNZj3vECO%20%20\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019165782357,"sku":"12047","price":5250.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/12047-1.webp?v=1779902437","url":"https:\/\/stationroadsteam.com\/products\/3-inch-scale-burrell-agricultural-engine-stock-code-12047","provider":"Station Road Steam","version":"1.0","type":"link"}
