Jcb 803 kingpost

[Holty]

Hello all new I’m new to the forum I have just bought a tidy 1995 Jcb 803 digger most pins and bushes are nice and tight for there age but the king post has a fit bit of play in it I was wanting to remove the top and bottom pin and have a look how bad it is weather it needs just bushes or pins as well maybe even line boring I’m guessing it’s a job for a puller I’m interested to see how people Have set it up to get the pins out

It'll need to be bad before it needs line boring. I made a puller out of a bit of M12 threaded bar and some thick washers, and turned down a top hat to engage on the bushes. Same set up to pull the old ones out and the new ones in. Your machine is a bit bigger so you might want to go to M16. Make sure it is the king post bushes and not the slew bearing.

Ok thank you will try that I’m guessing top pin will go up and bottom one will go down ?
