For later 240D 300D 300CD 300TD 300SD Models. Most after 1980, BUT YOU MUST LOOK AT YOUR PUMP BEFORE ORDERING! WATCH KENT'S VIDEO BELOW. You have asked for it, and we have delivered it again. Now that all those old power steering pumps are leaking out the front seal, we have come up with a kit that will allow you to replace the front seal of your pump at home without any special tools other than what is provided here. If you order the wrong kit, you will have everything torn apart, and the seal will NOT fit. We now include the rear o-ring seal and instructions on how to replace it. It does not leak as often as the front seal, but if. you are removing your pump; it is best to replace this seal BEFORE it starts leaking.

You will need an eight-inch C-clamp to replace the rear seal. If you do not have one you can purchase it separately below.
Here is what the pump looks like that uses the small seaL. It has a ZF blue part tag on it.
