Q Will chang­ing wa­ter pump make my blood boil?

Motorcycle News (UK) - - Garage -

My 2011 Yamaha R1 has a fluid leak from the bot­tom of the en­gine which I’m told is the wa­ter pump. Is it pos­si­ble to re­pair it by re­plac­ing the seals only? I’m a pretty com­pe­tent me­chanic, but if I think it’s be­yond me what would the cost of a pro­fes­sional re­pair be?

ACharles Marvell, Fl­itwick Mo­tor­cy­cles The job en­tails re­mov­ing the body­work, ra­di­a­tor and ex­haust, sump, the en­tire clutch and the oil cooler. Once all this has been achieved, the pump assem­bly can be re­moved from the bot­tom of the en­gine. The wa­ter pump seal can then be re­placed. It’s not a cheap job, I es­ti­mate six hours labour.
