<p>Thanks Dean, i may ring the tech guys from Timberwolf anyway. There were no shims inside as the last one seemed to melt and fuse itself and so we didn't fit another one so this may need to rectified as well. I'll keep you posted.</p>

<p>I've had to do two messages because the first was too long. </p>

<p>Timberwolf are very good on the forum, try them and see if you can get the temp reading off them if not and you don't know anyone in your area I can get the reading of Bob who posts on arbtalk, he has a machine, but it may take me a few week as I don't see him that regularly, let us know, regards dean</p>

<p>Hi Simon, yes they do get quite hot but should not be to a point where you can't touch them. If they are getting so hot you can't touch them it may mean the shimming is out slightly. What I would do is buy one of those laser thermometers, I think even screwfix sell them, they are fairly cheap nowadays and measure the temp after a set time, say ten minutes running from cold. Then either post your findings in the technical help section ( timberwolf have their own section on arbtalk) and ask timberwolf themselves, they may do the same experiment on a new machine for you or find someone local with a newish machine and do the same with theirs. But timberwolf should be able to give you an indication of what the temp should be after a given time of running.</p>

<p>It sounds to me like the shimming may be a little out if it is getting too hot to touch, if the shimming is out it puts too much sideways force on the bearings and produces heat through friction.</p>

<p>Hi Dean, just read your blog on timberwolf fins and bearing fittings. Just hsd mine gone again and they had only recently been replaced, all correct spec ie c grade. It looks as if 'and i quote my mechanic' the shims on the rear nose bearings melted and fused/welded themselves on the inside. It's all been filed down to size but my question is, after it has been run for about 10 mins should there be any heat from the bolt head in the middle. On mine it is hot to the touch, you can keep your finger on it, just about. Is this normal, if not any idea what may be causing the heat. Any info would be greatly appreciated as my mechanic seems to think this is normal but i'm worried as it is my money and without it i can't earn any. Kind regards Simon.</p>
