Unhappy Crankshaft scored... i really dun goofed

Hey guys,
it seems like iam that idiot that scratches his crankshaft while trying to remove the front main seal. I tried the "screw" trick to get it out but scored my crankshaft in the process. Now iam questioning my existance and how i can repair this mess. Is it possible to sand it down or polish it out? Or do i really need a speedi sleeve. If so can anyone maybe help me out by telling me which one i really need? My car is a 96´1.6 with the 8 hole hub. Any help would be appreciated.

You can order a repair sleeve from Rock Auto. No big deal.

Screw trick? Is that better than the Harbor Freight seal puller trick? I bet the actual correct tool cost less than the Speedy sleeve Plus freight.

the "screw trick" works great, if you do it right. none of those tries look right.

Yeah now i know. Talk about learning the hard way. So no polishing or sanding? Straight to the speedi sleeve?

You can try - but you also have to be willing to tear it back down again if it doesn't work.

And a leaking crank seal will deteriorate and kill a timing belt. I needed mine to last 6 weeks while I got another car on the road - it lasted 5.

Problem with those sleeves is you still have to pull the oil pump at least. The flange side pushes on first, then you pull yhe flange off, which would be behind the oil pump at that point... (I was going to do one for my rear main until I figured that out.)

???

The oil pump rides on flats that the sleeve wouldn't possibly slip over. I are confused.

You have to put the sleeve on flange side first, push it on, then rip the flange off. The flange is going to be behind the front face of the oil pump at that point and very hard to get to.

On the RMS one I have, the flange also limits how far back you can push the repair sleeve, which means you can't get it on fully with the crank in the engine.

I dont think that would be a problem. It certanly has been done before. You should be able to get in there with som needle nose pliers. I dont think i need to anymore.I got the f-ing seal out today using that same screw trick. The next shop which has the lisel deal puller is a continent away. i wetsanded the scratches with 600grit. Turnout was much better than expected. Tomorrow i will get 1000, 2000 and maybe some sort of polish cloth to finish it up. Here is the before and after.

Yeah, the screw needs to go into the hard part of the seal, not the rubber. Not gonna be able to yank it out by the rubber!

I also find drilling a tiny pilot hole in the "hard part" of the seal before even attempting to thread a screw into it helps a lot.

The Lisle 58430 seal puller works great for seals like this also.

After sanding it down with 1200 grit i got most off the deep scratches out. I installed the new seal with a bit of rtv on the outside.
What do you think? Should be okey i guess...
