Try Silikroil. Spray some in the cylinder and let it sit for at least 24 hours. If that doesn't do it repeat with another dose for another 24 hours. Let me know if that works, I'd be surprised if it didn't |

Hi there everyone, I was just looking for my pdf copies of the Sabb manuals to answer someones question about his gearbox when I found I no longer have them. I didn't make back up copies and a few months ago I had a nasty computer virus and lost lots of stuff. Unfortunately it seem the pdf manuals included. I went back to the Sabb site but they seem to have changed it and no longer have anything to do with their old engine, Pretty tight I think. Anyway does anyone have the pdfs that could send me copies. Kind regards Iain. |

One method I've heard about (but have not tried) is to weld a bead along the length of the sleeve. The contraction is suppose to shrink and loosen the sleeve so it can be pulled out easily,run a bead along the center of the cylinder and it will contracts and makes the diameter smaller just by a fraction, but thats all you need to pull it out. |
