First, read this carefully. I'm not going to re-use the bearings. Never planned on it. I am just looking for input on condition and wear patterns.
This past weekend I was able to split the case on a 2.2T engine I am rebuilding for my 914. So far the tear down has been great, nothing broken, no chunks of metal or debris, everything came apart without much fuss, and the case has time-serts. Case is apart now, most of the bearings looks really good, a few have some wear. I've had a few engines apart but not many, and those were special circumstances so I don't have a lot of personal experience reading wear on bearings. One case half (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297820.1.jpg) From one end to the other, close up's on each of them (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297820.2.jpg) This one seems to have much more wear than all of the others for the crank. (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297820.3.jpg) The dark spot here is oil. (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.4.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.5.jpg) Wear on the far edge of this one. (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.6.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.7.jpg) For the intermediate shaft bearings: (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.8.jpg) More wear here too. (IMG:http://www.914world.com/bbs2/uploads_offsite/c1.staticflickr.com-19709-1500297821.9.jpg) Any thoughts or input from you guys and gals? The engine was a core, unknown history. Buying it was a roll of the dice. |

Yes, I was firmly on the new bearings route, then someone on another forum mentioned that several have had issues with new bearings and quality control. That a lot of people have been getting their existing bearings coated (I assume like what Mark Henry does) instead. I understand that everything would need to be in spec for that to be viable though.
Hoping he can chime in, I'd love his recommendation. |
