More interested in the workshop than the rally field, he only ever steamed the Foden.\u003cp\u003e\u003c\/p\u003e\u003cp\u003e    First steamed in 2023 in the hands of a new owner, this one came to us described as in good mechanical order, fully certificated with a season's running behind it. Sounded ideal - a virtually new engine with a few outings under its wheels to sort out any teething problems.\u003c\/p\u003e\u003cp\u003e    If only things were that easy...\u003c\/p\u003e\u003cp\u003e    The first thing we noticed when it arrived was the lack of a gauge protector. Not a requirement - and indeed many of the engines that pass through our hands are not thus-equipped. But, on a boiler pressed to 180psi, let's just say we consider one a very reassuring presence.\u003c\/p\u003e\u003cp\u003e    Next thing - easy to spot, as there was no protector (see above) - was the cracked gauge glass. To his credit, the owner whipped the broken glass out and, after we'd cut him a new one, proceeded to fit it. Whereupon it broke too...\u003c\/p\u003e\u003cp\u003e    Having a closer look revealed that the top gauge fitting was a) out of line with the bottom fitting by nearly 3mm and, b) pointed in a different direction (and not in a way that it could be rotated to line up).\u003c\/p\u003e\u003cp\u003e    Whilst we can normally test an engine that comes in while its owner waits, we confess that this one defeated us (mainly because we'd run out of thick walled gauge glass). Sending him on his way, we said we'd report back as soon as we'd got it into some semblance of working order.\u003c\/p\u003e\u003cp\u003e    With the gauge pipework removed, annealed and reshaped so that the fittings aligned; a new glass fitted, and various other jobs attended to, we were finally able to steam the engine the following afternoon. The teething problems we'd assumed had been sorted remain, but they're things requiring some care and time in the workshop rather than significant expenditure.\u003c\/p\u003e\u003cp\u003e    Our workshop notes on this one read as follows:\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e    \u003cli\u003eWater gauge fittings need stripping and servicing - neither seal and one leaks\u003c\/li\u003e  \u003cli\u003eSimpling valve jams open when used, it needs a stronger spring. \u003cb\u003eThis is a critical fault\u003c\/b\u003e as it causes the engine to run away unstoppably if operated\u003c\/li\u003e  \u003cli\u003eSteam leak from injector union\u003c\/li\u003e  \u003cli\u003ePressure gauge reads 10psi high at working pressure - safety valves will need resetting once replaced\u003c\/li\u003e  \u003cli\u003eRegulator stiff to operate, it has an \"all or nothing\" action.

It will require work in order to pass a steam test, including servicing the gauge fittings, providing a gauge protector and replacing the pressure gauge.\u003c\/p\u003e\u003cp\u003e    The plain, unlined paintwork was done to a pedestrian standard when new - it has suffered heat damage on the boiler cladding under the motionwork, we would be tempted to strip it and repaint.\u003c\/p\u003e\u003cp\u003e    All that said, it's a fully assembled engine, in running order, which has had less than a year's use - current price of the kits is around £23,000 including the optional rubber tyres.\u003c\/p\u003e\u003cp\u003e    \u003cbr\u003e    \u003ciframe width=\"353\" height=\"198\" src=\"https:\/\/www.youtube.com\/embed\/_QT5M5-9IZ4?si=2RlXgT5xjr7902NM\" 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":54020071522645,"sku":"12754","price":16500.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/12754-1.webp?v=1779910429","url":"https:\/\/stationroadsteam.com\/products\/4-inch-scale-burrell-scc-traction-engine-stock-code-12754","provider":"Station Road Steam","version":"1.0","type":"link"}
