TW125 feed rollers

[64treefrog]

I am facing the task of replacing the feed roller blades on my chipper, badly worn, not helped by chipping my loppers!!

General opinion is that removing the blade bolts is a bastard.

I searched on here and found Aspenarbs post re welding nuts on. As my welding skills are iffy at best and I use a stick welder I see problems with this method.

Having years of experience changing blades I am aware of the importance of cleaning out the debris before fitting the tool.

Any advice please before I start. cheers

First try and clean out the heads of the bolts as far as you can. The deeper the socket fits in, the less chance you have of knawing the heads off.

I did have to weld on a nut to undo mine. I am not a skilled welder, but i use a mig weldrper which is much easier.

I think with a stick welder, as long as you can fill the inside of the nut up , it should be ok, and the heat will also help free up the bolt.

An impact driver is an invaluable tool too!

If you look at the same thread I did mine at Christmas just dot welds and hit with hammer and chisel to free them.

They are really difficult to remove and I don't think there has been many successes with just heat and tools on the job. What you have to equate it to is your valued time for that job. If you work it out to your hourly labour rate you may find just buying new roller bodies , blades and bolts would be financially astute against welding nuts or bolts to them ,very time consuming in itself ,and there are 24 bolts to remove ?

If not skilled enough I agree. But did mine in just over 2 hours so cheap.

2 hours is a great time . At £79 + vat each new roller body it is still a close run thing to some labour rates I here about for 2 hours work.

But you have still got to strip old bush's out and fit into new body and why would you do that. 

[Gareth Phoenix]

agreed , but if you have bought new blades and bolts ,and also the bushes and the only thing left to do is to remove the old blades , why go to the effort for £160 more,replace the bodies as well.a job that could take you all day (and lots of swearing). its a calculation to how much is your time worth. 3/4 hours tops all new or could be an all dayer or even 2. machine back at work in the afternoon.

We did a set the other week as the splined boss had stripped. Welded nuts to the bolt heads, the heat penetrated nicely into the bolt, removed with a socket directly, new boss fitted, blades sharpened, new bolts fitted and back together all within a couple of hours carried out by our 18 year old apprentice ?

Thanks for input guys. It did cross my mind to buy new rollers but as I've been living in Yorkshire for over 25yrs now I find it hard parting with 'Brass'. Will attempt job and see.
