Just wondering how stupid it would be not to replace the bearing when I replace most everything around it? It's just another $100+ dollars but damn that adds up fast. It sounded okay before, just wanted some thoughts. Thank you in advance.

I have several perfectly good used ones that I have not yet brought myself to throw away. If you don't mind pulling the engine it seems unnecessary. |

Shane,
How much is your time worth to drop it, pull the trans & redo it just for the TO bearing later? If your time is worth more than $100, then .... (IMG:style_emoticons/default/beerchug.gif) Tom /////// |

(IMG:style_emoticons/default/beerchug.gif) Tom /////// This (IMG:style_emoticons/default/agree.gif) I have many good used, and sell them at a discount, but it comes down to the fact that a used will not last as long as new. However, they could both outlast your use of the car. Hard to tell you which way is right for you. I leave good old ones in there, but I do this for a living so changing them is not hard for me (IMG:style_emoticons/default/smile.gif) |

If you have access to a small press they come apart easy.
Inspect the balls and races if they're perfect then I see no problem getting another 100K out if it. Clean and inspect, repack with a good grease (I use swepco 101) and press it back together. Last time I did 4 in under an hour. I've also done the super expensive 911 pull style bearings. The only issue IMHO I see with the ones I've done is the factory doesn't use a waterproof grease like the swepco. If a small amount of water mixes with the grease the bearings are shot in short order. I know some will say "you can't" or "I wouldn't" but I have several guy's using repacked bearings and in both of my cars with no issue so far. My '67 bug with a 911 (901) transmission is my summer DD and I have 5 years on it. To put a 901 in a VW bug the arm needs a major offset bend in it, so this bearing likely is stressed more than a 914 bearing. |

Cool thanks for the feedback, I never though about inspecting the bearing and using or replacing. Kinda like the old days with front wheel bearing. Thanks again!!!

I agree (IMG:style_emoticons/default/agree.gif) Easy to disassemble, inspect, repack with superior lubricant and reuse. Take care to lever the tin cover off with a few safety razors or a very thin putty knife. I've done it many times. |

Hi Mark, thanks for your insight and expertise on throw out bearings and many other subjects. I was looking at my throw out bearing my stock 914 (901). It looks like you press the bearing from the back side out of the housing? Then press the bearing apart? If you had a pic it would give me more confidence on this before I start pressing. Again thanks!!!

Is there anyone who could chime in? Maybe someone's done this before just wanted to know if the bearing presses out of the bearing housing from the back it looks like, then you press the bearing apart? Thanks for any insight on this (IMG:style_emoticons/default/beerchug.gif)

Thanks for any insight on this (IMG:style_emoticons/default/beerchug.gif) If no one else chimes in, I have junk ones I can assault later today and take pics. I have never done it and have hear of it being done. I have seen people using the grease repacking tool that looks like two funnels and a zerk fitting. |

One pic tells the anatomy.
Lever the race out with two fine screwdrivers. Don't damage the tin cover. Lever the tin cover off with safety razors or putty knives. Don't damage the tin cover Clean and inspect thoroughly. Retain balls (!) with new grease against outer race, install tin, use vise to re-install inner race. As they say in the mid-west...Walla ! Attached thumbnail(s)
