Finishing the Lifter Bores |
Finishing the Lifter Bores
|
 If you remember the last motor article I spoke of re-drilling the oil galleys after the sleeves were installed in the lifter bores. A lot of oil passes through this area of the motor and is pumped to the upper end of the motor. Forgetting to drill the galleys would lead to a motor that may last a couple minutes instead of many miles. |
|
 Sehr Performance has a table that that guides the block to the stationary bit. This 7/16-inch bit is 2 feet long and what amazed me was how straight it is. There is not a bit of deflection at the tip as it spins. |
|
 My camera caught the bit as it was spinning away, making it look like it's standing still. There are 2 galleys (one for each bank of lifters) that need to be drilled. |
|
 After the initial reaming of the galleys and now the drilling of the oil passages, there is a bit of debris that needs to be removed to get them nice and smooth. This photo shows the finish honing of the lifter bores. |

 As Scott Sehr was honing the lifter bores and I was snapping this photo he said, and I quote “I love my job!” Well Scott, I've got news for you – it shows in your work! |
|
 Here's a quick shot of the block after they were finished honing it. So now as I write this article and look at this photo, I sit back, smile, and think - “I love my job!” :) |
