Instructions for the use and adjustment of the 3640 Assembly Press
General
The 3640 Assembly Press has been designed specifically
for the assembly of 3M electronic connectors. All 3M
Locator Plates, Applicators, Platens and Cable Cutters
adapt to the 3640 Assembly Press to assist in the
assembly of a wide variety of connector and harness
assemblies. All of these items are purchased
independently from the 3640 Assembly Press.
The 3640 Assembly Press is a manually operated
portable tool that also can be fastened permanently to a
work station.
Set up requires a Locator Plate which is ordered
separately. Shipped with each locator plate is the
appropriate Shut Height Gauge.
Procedures for Adjusting Shut Height:
Shut height settings are guidelines for proper
termination depth. The adjustment settings are
specified on the chart provided.
1. The shut height adjustment is made from the base of
the assembly press without the locator plate or
platen in place.
2. Lower the handle of the press until the handle
casting makes contact with the press casting. (See
Figure 3)
3. Place the shut height gauge across the press base.
(See Figure 2)
4. Rotate the shut height to lower or raise adjustment
feature until the bottom of the shaft contacts the
desired position on the shut height gauge. (See
Figure 3)
5. Install the locator plate and the appropriate platen
on the press. The platen should be positioned
parallel with the connector body and cover.

3771 Base Plate (Optional):
The 3771 Base Plate provides additional stabilization
for the 3640 Assembly Press while maintaining its
portable features. It is available from your 3M
distributor. (See Figure 4)
Maintenance:
The press should be kept clean and lightly oiled
periodically. Use a few drops of S.A.E. 10 oil on the
six pivot points and press shaft at least every 5,000
connections. It is not necessary to disassemble the
press for lubrication.
