I usually don't remove any links, once I put them up. I have had some dead links become active again after being gone for as much as a year. If you hit a dead link, try it again in a minute, hour, day or so, sometimes even a week or two or more.
Or, if you hit a dead link, right click and then click "Copy Shortcut". Now paste it into the "Wayback Machine". It may be achived there.
If you find something you like, download it as fast as you can. DO NOT think it will be there waiting for you tomorrow. It might not last another hour. Service Manuals links come and go like the wind. Grab it NOW.
Some of these are in Adobe Acrobat. To save these PDF files, right click on them then left click on "Save Target As...". You will need to get the Free Adobe Reader to read them.
You can get it Here. 
Here is a FREE PDF Viewer/Printer that works great and is Much smaller than Adobe's
Sumatra. Another PDF Viewer that works good and is portable.
Lastly, if you steal all my work here, as some have done, it is OK. But at least give me a link back. Remember... "What goes around comes around."
