I do a lot of short runs of custom machining. Mainly for bikes and 'pimp my ride' type cars, but I do a fair bit for engineering purposes as well. My background is engineering but I had a 10 year-ish stint in Arb so I have contacts who get me to repair / machine parts for their broken stuff. Always happy to take stuff on.

No, the axle sheared just inboard of the wheel bearing so I had to get it out to machine the new bits. I was speaking to someone today who knows about these things and he reckoned that the over-centre bearings were such a pain in the arse they were only fitted for a short while on the earlier machines. I've come across them on machines I normally work on, but never on a axle bearing wallowing in mud. Theres more about them here........ Eccentric Locking Collars, V Series

For those that are interested, a bit of an update........ The collars in my picture do turn. They turn anti-clockwise as you look at the outboard ie if you were stood in the middle of the axle. Drift them round by about 1/4 turn, then they move on the shaft, which should hammer out. I had to penetrate the collars for about 2 days before they shifted but once they were moving they werent too bad. The shaft comes out easy either side, I found the best way was to use an air hammer. The vibrations seemed better than big whacks with a sledge. Hope this helps someone in the future if you're ever unlucky enough to do this job!!!

cheers, much appreciated

Thanks. Had plenty of heat and my 4' stilsons on it and it still won't turn. Didn't really want to cut it off as I need a fairly accurate shaft to copy when I make the new one. Doesn't look like I've much choice cheers for all your help anyway.

Sorry for the delay - I couldnt upload the pic from my ipad. Anyway, pic attached showing what I'm trying to explain badly! Trigger - Thats exactly what I'm after thanks. PM Sent. Graham - It looks like its gonna be gas axe time soon as I need to get it back to the guy for monday and I've got to machine some bits for it as well before then.

Morning. Thanks for your replies. The axle is a solid shaft incorporating the wheel bearings at each end and the sprocket for the drive chain (its a self drive model). It seems you take all the bearing assemblies off, loosen everything else and withdraw the axle from one side of the machine. Thats the bit I cant do!! Malcom was my first port of call. He was only interested in selling me the IPC for £50 and the bits. Ill machine the parts myself so he sort of lost interest at that point! Am off to the workshop now so I'll try to post some pics later.

Thanks for the reply. Ill take some pics and post tomorrow - should have thought of that! Ive removed the whhelbearings as it seems that once they are off the shaft should slide out. There isnt much else stopping it apart from 2 bushes which i cant shift hence this thread as I wonder if im on the right track.......

Evening all, Wonder if anyone can help please? Im trying to get the front axle off my 1625 stump grinder. Ive taken the wheel bearings off and slackened all the grub screws i can find and removed the bolts on the inner bearing housing, but i cant work out how to get the shaft to move!! Has anyone done this and can give Me some pointers please? Or even better has anyone got a copy of IPC so I can see how it all comes apart? Id be really grateful as at the moment im stumped. Pardon the pun!

Dont know where in North Suffolk you are but I always use EE Green from Yarmouth. They charge £40/h (4 hours min) for a 8 wheel grab with operator. Normally the 4 hours gets everything done i need

For what its worth - my dog drank 5l of the strongest glyphosphate and was sick but no long term effects!

! The intervew!!

My mate has B16 NOB, but its on his lorry and he's away so i cant get a pic

Yes they bolt on with 3 hex bolts each. I re-read the original post and checked some papers and it would seem one I replaced them on shed its fins at just over 1300 hours so I wonder if they need changing out before that as part of the servicing?? Not a good design - they are bolt on and alloy so any slight flex and they shatter over time!!

True! But if you look at his pics the blades are still there. I'm talking about the fins. Maybe i didnt write my post clearly
