Correct Con Rod Shells Help

Hi All,

Following my recent post I have manage to obtain the correct sizes as per the chart in the workshop manual so time to order my shells.

On the World of Triumph website can any one tell me why there are to choices for each colour shell for the con rods, for example part no. PFKL1182138 is a red shell however part no. PFKL1197406 is also listed as a red shell.

My assumption is that they are different in diameter to accommodate the different crank journals fitted to the later engine so if this is correct could any one tell me the correct ones to order for my 98 T595, Thanks

 

Thanks Oldyam, thought that might be the case, just wondered if anyone had had any previous experience and could remember
