sorting out lower link arms

pcp20us · Sep 16, 2016

Ha chaps..

Need to compare my tea20 lower link arms, see pic.

The left one looks like it has had the front connector that connects to the axle housing rewelded ( you can see it looks straight.

The right one is angled ( at axle housing) but it looks like the angle is to great.. so the arm is hitting the stop on the axle housing, Maybe there on the wrong side or been turn over....

Searched the net but could not find anything to to check this.

IF anyone has info or photos of link arms i would appreciate seeing them.

Cheers

You are correct, the arms are supposed to have the slight angle and it does look like it was repaired without the bend. As the left and right arm
are the same part, if you brought both to a shop to repair the one they would have a correct one to go by.

The lower links are almost straight at the pivot pins fitted to the transmission housing . There is a slight bend , only 10- 15 degrees at most . The angle needed to allow the links to fit the draw bar or implement is created by the movement in the ball sockets .
Hard to tell from your photo but the straighter one looks more correct , the bent one just might be on backwards .

A closer look at the pin end of the lower link arm showing a very moderate bend .

Thanks charles, looks light my right one is a bit bent maybe.

Gotta ask, do you have a howard reduction box and coverted your one wheel brakes to a hand brake.... Is this so you can you handbrake turns in the paddock,,, or maybe a bit of tractor drifting!!

Or maybe the right arms fitting and ball are just worn so much it sits on more of an angle... Had the link arm off recently and had the PTO shaft out, wish i had of checked the shank pin the link arm fits on, as i went to undo the nut to remove the arm later on and the whole bloody pin rotated.. quess i ll go back in and snug it up at some pint..

No way to ' snug it up ' easily

They are a fair B!t@h to get to . The right side is almost possible if you have small hands and are nimble ; remove the pto , weld a socket to a bent bar , be prepared to swear and curse for two hours ! The other side really needs the trumpet removed and diff centre out to do properly .

I checked my notes , the lift arms are 31,1/2 '' long from centre of ball to centre of ball , the angle is 10 degrees each end , overall length 34 inches . Bar thickness 1/2'' .
Make sure your lift arms have these measurements , they are often repaired badly which puts strain on those pins and loosens them .

Nice one. Those measurement will be handy to check them..

My thought too, being 60 year old tractor anything could be on there.

The LHS link arm has been welded and or straightened. As the arm going upto the lift arms was bent rather badly, so would say it has has a good shut on the LHS.

I read that you can get at the RHS nut from PTO shaft which i looked at when i had it out but did nt try to get a socket on there...Sounds like a bit of a mission.. Thaat why i want to sort that RHS lower arm to get pressure of that shank...

Read that to about the LHS shank, full pull down to do that one
