My brushes went on my pump so I was told and bought a few from Grippatank. I thought it would take me half an hour swapping it over. It was behind my twin stack hose reels so it was a bit of a nightmare. Took me 2hrs just getting it off and that was grinding the bolts off because they were allen key ones. Fitted 4 of my own bolts back on and tightened them up which took an hour. Nothing is easy in this game when it comes down to maintenance, now I realise why there is so few of these Oliver guys going about. ?
