Agricultural & Plant
At Barnes Auto Engineering we acknowledge that living in rural North Wales, means that we also have a great demand for repairs to agricultural and plant machinery, we are seeing an increase in the amount of agricultural and plant cylinder heads.
We offer cylinder head resurfacing (skimming), pressure testing and valve seat cutting for all makes of tractors. We also fit wet and dry cylinder liner which are necessary due to these vehicles working hard for many hours.
Marine cylinder heads and engine repairs are very common at Barnes Auto Engineering. We cater for all types of petrol and diesel inboard engines from 4 cylinder, 6 cylinder and V8. We recommend the fitting of brass core plugs and stainless steel water pumps etc. A common issue is sea water finding its way into the cylinders. This can have catastrophic effects on valves, seats and cylinder bores, all of which we can repair in house.
