The amount of belt that is above the pulley is called Ride-Out. All v belts should have a positive ride out to confirm the belt is not bottoming out, is contacting the sides of the pulley and to visually gauge wear. I have a Healey BT7 with 3/8” width nominal (0.380” actual SAE size) and I assume the BN2 has the same width pulleys. The SAE standard for Ride Out for a 3/8” pulley is 0.060 +/- 0.045”. Your 1/8” Ride Out is very slightly over but I suspect once the belt is adjusted and run in it will fall within the SAE tolerance.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There are metric pulleys which use a 10mm width belt that is slightly too narrow for the 3/8” pulley. A 10mm belt in a 3/8” pulley tends to sit flush or slightly below the outside diameter of the 3/8” pulley but this is not the correct belt. However, I suspect some will argue their 10mm belt works just fine and it probably will but you run the risk of the belt bottoming out and loosing the visual check of belt wear.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Probably way more information than you wanted but what else is there to do while in quarantine!</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Harold<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:healeys@autox.team.net">Michael MacLean via Healeys</a><br><b>Sent: </b>Tuesday, January 4, 2022 9:22 PM<br><b>To: </b><a href="mailto:healeys@autox.team.net">Ahealey help</a><br><b>Subject: </b>[Healeys] Fan Belt</p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>I recently bought an original style fan belt for my BN2 from Moss. $23.00 by the way. If you like in the picture below, you can see the fan belt sticking above the water pump pulley by an 1/8th if an inch. I know it is supposed to ride in the pulley against the angled walls, not bottom out, but this belt sticks above all three pulleys by 1/8th of an inch. Just don't seem right to me. The second picture is one of the generic belts that a few on the list suggested. As you can see it fits deep in the pulley and actually bottoms out in all three. That doesn't seem right either.
