Thread size for Volvo tamd61 raw water pump plate bolts

[sharpness]

Does anyone know what the thread size is for the bolts used to secure the raw water pump plate cover on Volvo Tamd61a. Reason I ask, I plan to make a couple of securing studs to aid keeping gasket in place when refitting the pump plate. Access for raw water pumps on Sedan 36 is ridiculous, so every little helps

I think your pump type is a Johnson F8B part 10-24315-01 see page 505 of this book. Page 410 has the parts list showing 1/4" 20 UNC x 10.
