VJ Posted January 5, 2019 Share Posted January 5, 2019 (edited) Im building a spare gsx1100g motor at the moment and a quick google shows that the bearing shells are the same for all OSS engines. Does anyone know the cheapest way to get the right set of shells in there? I have cases and a crank, im not sure if the crank came from these cases although I bought them from the same seller.

Gixer1460 Posted January 5, 2019 Share Posted January 5, 2019 'same for all OSS engines' is a broad sweeping statement and NOT factually correct! The Hippo engine was based on the 1127 cc engined GSXR family series - nothing else! If the crank is unknown then you can use the references stamped on the cases to give one half of the bearing sizing information but the crank journals need to be measured accurately to determine the ID bearing size required. Then you'll have to use a sizing chart to determine the correct sizing - there are 3 sizes available for the mains and 3 sizes for the rod big ends - so lots of combinations. Unlike with cars, lorries etc. bearings are generally only available OEM - no aftermarket suppliers, no shortcuts! Quote Link to comment
VJ Posted January 5, 2019 Author Share Posted January 5, 2019 I stand corrected, that'l teach me to believe an Eblag advert Cool so i need my manual for the comparison chart and then a 25-50 micrometer on the journals and then i should be good to go? Rods are in place on this crank so at least thats saved some money. Any preferred supplier for the shells? Cheers John Quote Link to comment

fatblokeonbandit Posted January 5, 2019 Share Posted January 5, 2019 (edited) work out the colours and get the part numbers and stick them in Eblag, i got this lot from Trumpland for £10 each pair!!!! In robinsons they are £18 each and you need 8 big end shells, soon gets very expensive.... mains are £10 each shell as well... Edited January 5, 2019 by fatblokeonbandit Quote Link to comment
VJ Posted January 9, 2019 Author Share Posted January 9, 2019 have worked out the ones I need now, found 3 on Eblag in the uk for cheap so got them. did you not get tapped up for more from customs for the US import ones? Cheers John Quote Link to comment
fatblokeonbandit Posted January 10, 2019 Share Posted January 10, 2019 Nope not this time, it seems entirely random, as I have payed duties sometime and not other times Quote Link to comment
