Replacing bearings on an old Elu MFF80 electric planer

[simonharper]

I have just gotten hold of a beauty of an Elu planer (pre Black and Decker) .The bearings are a little tired so I have replaced the ballbearings with SKF's
The problem I have is with the removal of the small needle bearing for the cutter drum.
It is pressed into a blind hole. I have used my blind hole puller ( slide hammer with expanding collet type) on it but it just wont budge and I don't want to crack the plastic casing with too much mmmf. Any one with any experience with this?

I don't know the item in question but would a gentle warm of the plastic housing with a hair dryer expand it a little - well faster then the bearing so it may be tempted to come out with your slide hammer?

how did you do it eventually?

sorry .just seen yr post
the bearing is indeed a press fit into plastic and the new one went in with finger pressure . Dont know why the old one was so impossible and believe me i really gave the puller some wallop.
I spoke to an ex aircraft mate of mine who immediately said 'dremmel' so thats what i did and 15minutes later 'hey presto'
The irony is that the machine is no quieter than before , with four new SKF bearings. Brushes were hardly worn. I put some new blades into it.
I feel better for doing the bearings but now realise it probably was a bit of a waste of time. The machine was really tidy when i got it and didn't look like it had a great deal of use
Anyway the machine is great and planes beautifully plus i did only pay £20 for it.
