If you have the tool it won't be bad. Just take your time and you'll be fine.

Make sure everything is clean and get the tool indexed right. Wipe out the excess compound before it sets. Really not a bad job with the tool.

What do I have to index?

The install tool will most likely have to be attached to the head a certain way. It may seem like it is working if you put it on the wrong way but the cup won't fully seat.

don't forget to drop a penny in the cup before you try to remove it, to stop all the shavings from going in the cylinder.

From looking at it , it seems there is a o ring on the tool where the cup gos on to then I tap it in . I think

Yes, it looks like you need to use a hammer to drive the cups in with that particular kit. Just follow the directions on the website and you will be fine.

Make sure you use some pipe cleaners or a tool of some sort to scrap the old sealer out. Brake clean and air on it to get all the bits out doesn't hurt either. And it needs to be the green sleeve retainer loctite. When you drive the new cups in, listen for the change in sound when it bottoms out and then give it a few more good hits to get it fully seated.

Yes, a tool that doesn't require you to hammer in the new cups, or taking it to a shop to have it done.

Who makes this tool?
I have the OTC kit and the Rosewood both you have to hammer in the cups to seat them, FWIW I prefer the steel OTC driver to the aluminum Rosewood kit.

A touch of heat on the old cup can help break a stubborn one free.

The new Riff Raff kit does not use a hammer to install the new cups it is so much nicer of a job on 7&8 with the new kit. Makes it worth the money IMO

when you get all the coolant drained and cups out, look down in the head and youll see where the face of the cup sits. there is a penny sized amount of locktite that needs to be broken up and removed. I found using a long pick really helps with a small vaccum attachment to get the remains.

i have used Jims tools serveral times, it works great. just make sure to get a good bit of turns on a cup before removing. the tool will start to get tight, dont be afraid to get a couple more turns on it for insurance.
