Tony , i have an injector tester of my own , just a classic one with gauge and pump , and for timing : some equipment i can use some equipment from a another boater which profession is bosch specialist , its not of my own .
Oh yes an little tip for those who has an injector tester and didnt want to remove the injectors, but want see what the oping pressure is : , it is possible to connect them with the injector tester only remove the high pressure pipe for the DPA pump and connect the test pump and see the opening pressure and if needed adjust them . i know with this method you cant see and clean the injector tip , but you dont need new rings etc. , the test pump i connect to the floor frame near bij the injectors and the line on the test pump was of soft copper .
The waters i,m sailing its is very diffirent , from small waters, lakes and canals (yes we have also in holland! ) and also waters like markermeer/IJsselmeer and zeeland and also the big rivers like the waal , the waal is one of the most riskful rivers in nl. it means its Always very busy with big ships and heavy downstream , on this waters it is very dangerous to had a failure , engine must be in good condition otherwise it dont have a good feeling for me .
enough spare parts is a must , the T90 never disappoint me , the only failures i had in 15 years , a clogged fuel filter (remove on the river in a few minutes ) and an broken built in waterpump also on the river , the pump was completely stocked and the V belt was nearly burning , to save myself to a save plave , i cut the V belt with a knife and run the boat downstream deadslow running without cooling circulation to a safe place and remove the pump for a spare one . the broken pump was a new one , i asked the importer how this was possible , they told me that is was chinese made and many customer came back with the same problems , i got my money back , since that time i order my parts in the UK. , found the adresses on this fantastic forum .
