Thread: Td5 Fan shaft still got slop in it with a new bearing

Noticed I had plenty of wobble in the fan so I've replaced the fan bearing with a new SKF one. Unfortunately after I shrunk it into place there's still a ton of slop

This had been repaired with bolts going through the housing and pushing on the bearing. Others will have the details.

[emoji848] ..... by “shrunk it in to place” i assume that it was necessary to freeze it to be able to insert it into the housing. Was it a sliding fit going in or did it also require application of heat to the housing to get it seated ? ....also did you refit the retaining circlip?

Didn't try without it, froze the bearing and heated the housing. Did installed the circlip. Once everything had returned to temp I could still slide the bearing back and forth a little bit. I did double check the bearing and it's the right one from skf.

That's not good.
The bearing will be spining in the housing and flogging it out more, it needs to be an interference fit.

In cases of only being rightly loose, e.g. a push/slide fit, Loctite bearing retainer will work, otherwise the bore will have to be sleeved or the housing replaced.

Will give loctite a shot, else I've got a 16p engine that's going to go in sooner rather than later. Thanks for the help all, wanted to make sure I wasn't making some stupid mistake.

I had a housing like that a few years ago. To get out of trouble, as I was not in a position to replace housing, I drilled and tapped 3 holes (M6 from memory) on housing at 120 degree spacing and inserted short screws. They were only nipped up enough to stop the outer race from rotating and locked with a jam nut. Not a perfect fix, but got me out of trouble. Charlie
