What can I do about sloppy pivots on sc252?

[066blaster]

There is some play in the "pivot" or pins,not sure of the correct term but can these be fixed somehow? I know they will only get worse, so I would like to fix them now. The machine has 1400 hrs on it.

In the thread about upgrades to a 252, needle pin bearings are suggested for replacing the fast wearing plastic bushings.
Others have used them with success.

My concern about them is, that they may cause wear to the mounting holes.
Needle bearings need grease, but dust can get in there, as there is no seal.
Dust and grease between bearing and mounting hole seems not good for my understanding.

So for now I went the save way and purchased bushings from vermeer.
In my country they where 8$ each and look like a cut off piece from a plastic pipe. You need 4.

Maybe it's better to wear out plastic bushings instead of non replacable metal on the machine.

Maybe I am wrong and one of the needle bearing useres can comment the longterm reliability.

How do I get the thing apart?

It all come apart quite easily. Simply drive out the pin and bushing and put it back together. Bushings are cheap and easy to do.

We drilled the pins and installed grease nipples in them.
1400 hrs and still on the original bushes.

Could someone give me a step by step on getting them apart. Do I have to remove the bolt on the bottom. Or just pound the pins out from the top? What's holding them in place?

I bought the thing used, I have put about 75 hours on it. Not sure what previous owner did as far as maintenance. It has a new engine. And green teeth setup. The thing looked like it had been sitting outside for a couple years. I sanded and painted it.

It's a very easy process... First ,remove the thru-bolt.. drive the pivot pin down & out,,swing the cylinder out of the way..remove the factory-type "plastic" bushing ( sometimes they are a bit difficult).. clean out the bushing bore.. Carefully line up the new bushings & drive them in.. (Hint: Don't hammer on them directly..use a wood block )..swing the cylinder back onto the pad, line up the pin (tapered end up) drive it back in , line up the thru-bolt and install... easy peasy, Bobs yer Uncle
