944 Torque tube bearing maintenance

Changing torque tube bearings is a time consuming project as we all know. When you have taken tube off your 944, removing saft and bearings is quite easy and fast job to do. With son's project we removed saft & bearings with electric winch. It works quite fast, about 40 seconds, as you can see from the video

If want to rmove saft even faster, about 5 seconds, it can be done with proper tools [;)]

This is a 1983 944 tube which was sent to us for some overhaul.

As you can see we used very high tech tools to remove saft & bearings....in our case a house, old Subaru, broken 968 tiptronic damper and some rope.

Bearings we removed with very slow ghetto-method. Want do it again, have already a new fast working tool for this job as well. If you do it just for your own car this method can be used.

Since this is 1983 tube it has old style bearing carriers. You must drill out the rivets to have a possibility to remove bearing from a carrier
Central plastic sleeve is also pressed in, so you need some innovative hightech tools...

Great stuff as usual and important for me as I need to keep an eye on my torque tube, we think a bearing near the front is dodgy as its got a bit noisier than I can recall. Could be clutch but the clutch, fork and throw out bearing were all replaced about 10k miles ago.
 
Here's some I took of my rebuild: https://picasaweb.google.com/102381013786850618724/944TorqueTubeRebuild?authuser=0&feat=directlink

I used these bearings as a bit of a trial: http://simplybearings.co.uk/shop/p7929/SKF+E260062ZC3+Energy+Efficient+Shielded+Deep+Groove+Ball+Bearing+30x55x13mm/product_info.html
 
Thanks guys,

"Subaru method" was fun & fast to remove saft.

With this '83 tube we are going to use Koyo bearings, also C3 tolerance. In son's project we have SKF C4's, couldn't find C5 as original were. C4 ones cost double compared to C3 ones...
 
Looks like I need to invest in a Subaru. Last time I proceeded with the ghetto method I probably invented new swear words...
 
My father-in-law gave Subaru to me. He is 75 and wanted two years ago buy a new car for himself (the last one as he said) Local Subaru sold a new Forrester to him for a bit lower price when he didn't had this 20 years old Legacy as a trade..... He asked then if i want to have it. Actually Subaru have been quite good to tow car trailer etc.
Here it can be seen bringing son's project to his garage

Yeah, I just wonder if this means some reduction in longevity but I guess I won't find out until somewhere down the line...
 
First the bearings were put back to carriers again. Since these were older design carriers, some welding was used to put halves back together again.
