To remove 99% of VHS video heads (Betamax are much more difficult,
especially in aligning the new head), do this
1) disconnect the wiring on top of the head drum. This may be a series of
flexible wires (yellow, red, brown are the usual colours I think), or a
PCB. If it's wiring, just unsolder the wires going down near the spindle.
On a PCB type head, unsolder all the marked connections (look at the new
head to see which ones are not connected. On a few machines (NordMende  (I
think JVC deck mechanics)), you unsolder everything and them lift off the PCB
2) Remove the 2 screws on top of the drum near the spindle
3) pull off  the drum. if it won't move, either bollow a video head
puller, or gentle warm the drum e.g. with a hair dryer.
4) put the new head, right way round (match up any white marks on head and
spindle) on the machien
5) screw it down
6) solder the connections back
DO not apply any force to the pins coming out of the loer drum that go
through the PCB on the head. Make sure they are all free before removing
the head. Solder them back after screwing the head down. You can easily
damage the rotary transformer in the lower drum, and a new lower drum for
a high-end machine can cost #250.00 (about $400).
