Fixing INJECTION PUMP LEAKAGE in a small 3 cylinder diesel engine

Hitachi EX22 mini excavator has been leaking diesel fuel a long time from injection pumps top... Time to fix it even it is not recommended as a DIY job to tamper with injection pumps.

Hitachi is equipped with Isuzu 3KR1 engine but these injection pumps are pretty much similar in other engines like Kubota too. You might want to learn something new to by watching my errors!?

If Your injection pump reads Zexel in it then this video is for you too

I bought my repair kit & 5 flat screw special tool from UK:

Delivery valve holder O-rings were bought separately (2 pcs per cylinder 6 pcs together for 3 cyl. engine) from Korja-Kumi Tampere 0,32€ per piece
