Below is a sample of the 1100 group of the new numbering system. We saw this earlier, in the ‘Getting Started in 2013’ series I wrote last month. I am going to slightly change the system of numbering to make engine building easier to organize. It is a subtile change, but an important one. I pick this simple group to show the before and after, and to explain why. Very shortly I am going to come back with the final revised numbering system, and print it all out here. We are going to change our own parts numbering system on our catalog page on our main website to match the new system, and we will have a vastly better organized system for builders to work with that will provide a very orderly path to a running engine.
Below is the original numbering system from last month. Note how the group is 1100 and also the camshaft itself is part number 1100.
Cam group (1100)
1101- Thrust washer
1103- Cam gear
1104- Hydraulic lifter set -12 total-
1105- Cam lubricant
1106- ZDDP oil additive
Ok, here is the change: Notice the group stays the same, 1100, but everything moves down one number. below this I will explain the why of it.
Cam group (1100)
1102- Thrust washer
1104- Cam gear
1105- Hydraulic lifter set -12 total-
1106- Cam lubricant
1107- ZDDP oil additive
Now, picture yourself building an engine with the new numbering system. As I will show everyone shortly, there are 40 different groups, each with their sub component numbers. We are going to have a checklist for builders with the 40 groups on it, so a guy heading to a college to close his case will know that he needs to have all the sub components so he can ‘check off’ groups 1000, 1100 and 1200 from his list.
The new change eliminates confusion between a builders speaking of ‘having part 1100’ which was just the cam, and ‘having group 1100’ which are all the items listed above. The simple number change above fixes this.
Second, we are moving toward a system where we will be able to offer an entire group in one box, instead of just some parts of the group. for example, Lets look at the Oil Pan Group (2200).
Oil Pan Group (2200)
2201- Oil pan
2202- Oil pickup
2203- 1/4″-20 hardware -19-
2205- Oil pan gasket
2207- Dipstick bracket
