Jonboy Posted September 7, 2015 Author Share Posted September 7, 2015 Still ran really nicely on tickover, just sounded awful as soon as any load was applied Quote Link to comment
Rene EFE Posted September 7, 2015 Share Posted September 7, 2015 I bet it stopped at some point Quote Link to comment

Blubber Posted September 7, 2015 Share Posted September 7, 2015 Looks like a donor engine might be cheaper Quote Link to comment
Gammaboy Posted September 7, 2015 Share Posted September 7, 2015 750 plain bearing engine? Quote Link to comment
Jonboy Posted September 8, 2015 Author Share Posted September 8, 2015 (edited) 750 plain bearing engine?no, 1000 roller crank engine.. or did you mean replace the whole unit with a 750 one?.. Edited September 8, 2015 by Jonboy 5am stupidity Quote Link to comment
Gammaboy Posted September 8, 2015 Share Posted September 8, 2015 I thought it looked like the kind of debris you get from plain bearing failure - when my GSX1100 crank ate it's bearings it looked nothing like that!I certainly don't recognise the big brass? chunks! Quote Link to comment
Captain Chaos Posted September 8, 2015 Share Posted September 8, 2015 when my GSX1100 crank ate it's bearings it looked nothing like that!try harder then. 1 Quote Link to comment
Gammaboy Posted September 8, 2015 Share Posted September 8, 2015 Hey, there was plenty of bearing metal in the bottom of the cases - it was all hardchrome slivers though. Oh, and bits of cam lobe and rocker pad... 1 Quote Link to comment

Locomotion Posted September 8, 2015 Share Posted September 8, 2015 Firkin el roller cranks are usually tough, what do you reckon happened to cause that Quote Link to comment
Gammaboy Posted September 8, 2015 Share Posted September 8, 2015 They're tough, but high mileage roller bearing cranks start lifting the hard chrome from the oil hole drillings. I think in my case the crank failure was driven by the welded/ground cams spitting an inclusion out... whatever way you cut it, I was down a few crank bearings, and the cams and rockers were trashed (bearing material wound up blocking the oil feeds in the rocker shafts) Quote Link to comment
Jonboy Posted September 9, 2015 Author Share Posted September 9, 2015 Firkin el roller cranks are usually tough, what do you reckon happened to cause thatNot sure at the mo, only stripped it far enough to discover what was wrong and then stopped. Engine is now out of frame and will be heading to a new home soon. Meanwhile, got to order some gaskets etc for top end of 1170ET lump which is going in the GSish 1 Quote Link to comment
