I have had several requests asking me to supply the special bolts needed for the installation of an oil filter, and/or monitoring the oil pressure at the main oil galley.
The dimensional details of the special bolts can be found in the "Guides" found at
www.modelaengine.com and they can be made on a screw cutting metal lathe.
The large special bolt is only needed if an oil filter is used because it returns filtered oil to the main oil galley.
The small special bolt replaces a valve cover bolt and can be connected to a pressure gauge to monitor the main oil galley pressure and/or supply oil to an OHV head conversion.
I had 100 large and 100 small special bolts made.
The bolts are made from 6061-T6 aluminum alloy and the large bolt will yield at just over 55 lb-ft of torque.
The price of the large bolt is $20.
The price of the small bolt is $10.
In the USA, USPS small box flat rate postage is $8.45 whether there are 1 or 25 bolts in the package.
