Hi Gang,
Bump---To bring this back to the top





diamond grinding wheel dresser
this tool you dress the grinding stone to the different angles for the valve seat in the head
great tools but the training manual just doesn't have all the answers it would be nice having experienced helper

I dresssed the grinding stone to 45*
I did all the intake valves seats to 45*
now I'm thinking I should use this diamond wheel dresser to change the angle to what ever the other two angles?? are

then doing the next angle on the grinding stone dresser
then grind the 4-intake valve seats
dressing the wheel to the next angle
then grind the seats again to this angle

my question is would I dress this same wheel (45*) to the other angles ??
In my 1955 VW transporter manual the VW valves seats are 75* 45* 15*
Then in a 1963 Trade school training manual showing the two tools above----- they grind American car valves seats to 60* 45* 20*

I haven't found the three angles for the Volvo motor we are rebuilding
but expect to have that info tomorrow

Does the exhaust valve seat also get the 3 angle grind?

I ordered up 4 new exhaust valves
thanks
