Yes, our neighbor at work is an industry parts dealer.
I can find here special greases, bearings, o-rings and quite all the seals I need. Plus the tools needed to pull bearings or make an oil pressure gauge to test the left mileage in the oil pump ...
The only bearing they could not have (as far as I know) are the needle bearings into the valve rocker assembly.
They are very friendly (I change them from their boring work selling the same bearing again and again.... )
