Front rotor question

Here's a quick question for you front rotor experts. It's on a 79 ROW 930. What's the preferred method of removing this center cover. It has a threaded attachment - does it just pull out? Maybe with a slide hammer? None of the information I have specifies. Thanks!

You can use a slide hammer with a bolt welded to the end. Make sure it's a heavy enough weight on the end. Maybe 5 lbs.

As I recall the last time I did that job I used a 10 lb weight and had a bold through the center with washers, and a nut, just tightened it and pulled right out

I used a harbor freight slide hammer and the threaded boss popped off the cap, it's spot welded on.
Had a guy tig weld it back on which also attached it stronger to the cap and now the slide hammer works fine.

Interesting. I like the idea of using a bolt and washers through some type of device like the 10 lb weight. I might try that first since I can probably piece something like that together in the garage. If not, I'm headed for Harbor Freight. The main thing is knowing that it just pulls straight out. Thanks again - Doug

I used this for awhile until I made the puller.

Point of reference, a 79 930 has a different hub and bearing cap. Someone must have updated to later style hub and nonfloating rotors on your car. Probably to save money on rotor replacement costs. i like the pulling fixtures as opposed to impact like a slide hammer. it is easier on the welded nut on the cap that way.

Drilled a hole in a short piece of 2x2, run abolt throu and thread into cap.
Couple light whacks on the 2x2 with a hammer and it's off.. no fuss no muss & nothing special.

I didn't have a steel plate so I substituted a piece of hardwood (oak) and just pulled out the cap. I tried a piece of 2x4 but it was too soft and just poked through.
