Top Block
Assembly instructions are interchangeable between all sizes of the GreyT Top Block. For the purposes of this User Guide, the 2” GreyT Top Block is used as an example.
Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.
Step 1
The 1/4” ID x 5/8” OD bearings will sit in the slots in the Top Block. A ziptie can be used to hold the 1/4” Dowel Pin in place to make assembly of the Top Block easier.
The table below shows the Dowel Pin size used for each Top Block
This step must be repeated for both halves of the GreyT Top Block you are assembling.
Top Block Tube Size | Corresponding Dowel Pin Length |
1-1/2" | 1-1/4" |
2" | 1-3/4" |
2-1/2" | 2-1/4" |
3" | 2-3/4" |
Step 2
Slide on all components in the order shown in the image below.
The table below shows the #10-32 bolt length, #10-32 spacer length, and CF Spring width for each size Top Block.
This step will be repeated for both halves of the GreyT Top Block you are assembling.
Top Block Tube Size | Bolt Length | Spacer Length | CF Spring Width |
1-1/2" | 2" | 1-1/2" | 1/2" |
2" | 2-1/2" | 2" | 3/4" |
2-1/2" | 3" | 2-1/2" | 1" |
3" | 3-1/2" | 3" | 1" |
Step 3
The assembled halves from Step 2 should bolt together. Make sure the #10-32 Spacers are fully seated in the Top Block pockets before tightening the bolts.
The Top Block must be assembled with the CF Springs in the correct orientation shown in Step 2, and in the image down below.
