<p class="MsoNormal">The reason they state to not use washers is they are afraid that the washers used will (1) not be hard enough and will compress under the bolt head and (2) all ARP bolts have very liberal radii between the head and shank. If there is a
tight fitting washer this would be strain on this radius and could break the head.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The 7/16” ARP bolts used on Chevy flywheels is what I fit to TR’6, late Spitfires and modified TR4 cranks. These bolts come with the special washers to use with them. I have used a proper washer under the 3/8” ARP bolts many times with
no problems using a correct washer. You can also use an ARP crown wheel bolt for the same purpose and these come with proper washers.<o:p></o:p></p>

<p class="MsoNormal">I just got a set of ARP 206-2802 flywheel bolts from Pegasus for the TR4. They are for “BMC A series”. The instruction specifically says, “DO NOT USE ANY WAHERS”, yes, all in caps for emphasis! They further state that ARP will not be
responsible for failures is washers are used. The instructions also say, “Make sure there is an adequate chamfer under the bolt holes on the flywheel to clear the radius under the head of the bolt.” Torque is 55 Ft-Lb with specified lubricants on the threads.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve never had that much good luck grinding the ends of bolts and still having it square so as not to start it cocked and runing the female threads. Maybe it’s just me<span style="font-family:"Segoe UI Symbol",sans-serif">😊</span><o:p></o:p></p>
