The Middleton Railway has a Peckett 0-4-0 diesel locomotive, which is unique. It has a Gardner 8L3 driving a Wilson gearbox through a fluid coupling, similar to an 04. It has recently suffered from a broken compressor drive belt which is proving almost impossible to replace. The old belt is a Brammer link belt. It measures 28 mm across and about 20 mm deep, which is a totally non-standard size mid way between a C and a D belt. The groove are 26mm wide by 26mm deep. Our regular suppliers (Eriks) have failed to find a replacement and Googling has also failed to find anything. It has to be a link belt as it goes around the transmission. A C belt is too small to fit the grooves and a D belt is both too wide and the small pulley dia is too small for it. If we can't find a replacement belt, it will be a major job replacing the drive pulleys with an alternative size due to space considerations and an otherwise good loco will be out of use. Has anyone come across these belts/knows a source/has any spare belts?
