Bob Grundy Posted October 11, 2020 Share Posted October 11, 2020 The Rolls Royce B61 is more powerful than the B60 used in Ferrets and Pigs. B60 4.2lt & 120bhp and the B61 is 4.8lt & 140bhp. Would any one be interested in the B61, I will be getting some take-outs shortly. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted October 11, 2020 Share Posted October 11, 2020 Hi Bob, I rebuilt a B61 a few years ago for a Dennis fire engine. Goes well, twin SU carbs! Would be good to convert one for a Ferret..... or a Humber Quote Link to comment Share on other sites More sharing options...

Bob Grundy Posted October 25, 2020 Author Share Posted October 25, 2020 This is the best B61 out of the four that I have. It was reconditioned in 1974, you see it as it done then ready for service. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted October 26, 2020 Share Posted October 26, 2020 Hi Bob what was that B61 configured for? The only B61 engines that I knew of in MoD were in RAF ground equipment like aircraft starters.. I notice the fan is reverse flow, ie drawing air from engine so looks like it could be from a generator. Quote Link to comment Share on other sites More sharing options...
Bob Grundy Posted October 26, 2020 Author Share Posted October 26, 2020 Richard I had heard that they were used for starting jet engines. I have no idea how that was accomplished. There seemed to be a few around as I saw about half a dozen at a farm near Chester a few years ago. Quote Link to comment Share on other sites More sharing options...
Whittingham warrior Posted October 27, 2020 Share Posted October 27, 2020 Hi Bob Are the take outs you've got seized or are they free? Have you tried to start them if they are not stuck ? Thanks WW Quote Link to comment Share on other sites More sharing options...
Bob Grundy Posted October 27, 2020 Author Share Posted October 27, 2020 Today I have had one briskly turning over by two 12v battery's. I have yet to have a go with the others, however I am not attempting to start them. Quote Link to comment Share on other sites More sharing options...
