Should be a fairly straight forward job to remove the bearing and aluminium housing. Just remove the 2 bolts and the plate will come off. You should be able pull the housing out then. As for what you replace then depends on the type of housing and how long the bearing has gone for. There’s one type of housing that’s mad money from what I remember. You may get away with just taking the bearing out of the housing and replacing the bearingI bought a s/h wagtail over the winter for handy money. Just going through it today and I noticed a bearing is gone in the flywheel that joins onto the Y piece. It has two bolts holding the bearing in. Are these hard to change or will I need a mechanic or any specific tools?
Also, make sure the end of the wishbone that sits into the bearing isn’t worn down. If it is, again depending on the housing and bearing, you may need to put a new sleeve on it, try and build it up, or replace the wishbone. Stick up a couple of photos of the aluminium housing and bearing, as well as the wishbone when you get it out. There’s 3 different types from memoryThanks. I’ll take a spanner to it and see how I get on so
You're going the right direction, there is a plastic band that goes around the aluminium housing to prevent it corroding to the housing but it didn't seem to work in your case. Try hit it around the edges with the hammer from behind because if you hit a thin part it'll break.Just an update on this. I’m after giving the aluminium housing a fair bit of hammering and wd40 but she is refusing to budge. Is there something I’m missing? I’m hammering it towards the tractor
