Welcome to EE!
The engineering drawing should have a default tolerance block on it somewhere. Many organizations use the decimal place method.
.xx = +/- .03
.xxx = +/- .010
.xxxx = +/- .0010
The diameters have distance dimensions associated with them that are .xxx. So, the cylinder to cylinder location tolerance should be +/- 0.10 should this be the default tolerance case.
If there is not a default tolerance specified you need clarification.
