Description
O-Ring to the front pump bolts. At the front of the gearbox, behind the turbine, there are 8 bolts that hold the oil pump to the gearbox. Some gearboxes have sealing washers under the bolt head as a seal, but there are also some that have an O-ring that sits in a milled groove on the bolt. If you have sealing washers, the dimension of the bolt head is 1/2″. If you have the O-ring type, you have a bolt head that is 9/16″. 8 O-rings are required for a gearbox
