Tea20 Top linkage

Hi Folks
Taking a closer look at my Top linkage area I noticed that the pin going through does so flush one end but not the other is there a reason for this as it looks as though it should push through more???
Thanks

That looks like it has been subject to a severe field repair. :) Is it a solid one piece pin? It is supposed to be hinged in the middle.
 
Have you ever had the pin out? There is supposed to be a single bushing in the center that is wide enough for the rocker to just fit on.
Do you have 2 bushings one on each side that slip into the rocker? If so, I'll bet someone cut the shoulders off the original bushing and it is frozen into the boss on the rear end housing.
 

You will need to replace the entire rocker link in any case , there is no way that yours can be repaired with any certainty .

Removing the old bush calls for care , too much force can result in you breaking the flange off the transmission casting .

You did not really say, but can you/ have you pulled the pin or rod that goes through the rocker out? If so can you post a photo or two?
 
Hi
No I have not yet attempted to knock it out
and to be honest I'm not sure I want to
after seeing what can go wrong.
If it functions the way it is then maybe I
should just leave it.
If I do then I will cut through either side
of the flange so that I'm only having to
knock back a small sections at a time.
Is the original pin and bushings still
available.

The problem Charles is speaking to is the driving out of the bushing. Depending on what you have there, I may have a cheap and easy fix. If it was me I would try and drive just the pin out. As seen from the back, it should come out right-to-left. A quick search found this... http://www.ebay.com/itm/Ferguson-tractor-lift-rocker-pin-TO-20-30-35-Tea-Te-181060M91-TO-561-/231857127182
 
Hi Ron
Why is the pin hinged on the middle???
I'm sure I may be able to get a spare part
from the wrecking yards over here.
Thanks
 
An owner before me had cut the bushing on either side of the boss and inside the rocker with a hack saw or more likely a body grinder with thin blade. I am guessing it was to do a weld repair on the rocker. My problem was without the bushing holding the rocker on axis, when ever I lifted the 3PT hitch to max. the blade would bounce. The same bounce you get when you do not have the top link yoke snug enough.

I bought a replacement rocker from a tractor wrecker, that is why it is red :) , and also got 2 new bushings. The bushing on the left I believe is normal length, the one on the right has been cut to fit. The amount cut off is about the same as the width of the washers.

The pin hole on the left is the same diameter as the bushing for normal installation. The pin always has to go in from left.

I tried to get the old bushing out, but I do not have a torch to get it hot enough. Take a look here on one guys attempt to remove the bushing, successfully. http://mytractorstory.blogspot.ca/

When you pull the pin out from the left it is too long and hits the fender. You pull it part way out, bend the hinge, the pull the rest of the way.
 

Both the ' Grandfather pin ' and the rocker are easily found new . It may be worth buying new ones as older ones sometimes have significant wear .
The damage I showed in the photograph is not mine ! :shock:
It was caused by an idiot going mad with a sledge hammer . There are many ways of removing the bushes , the easiest is to weld on the inside , the subsequent contraction of the weld drags the bush inwards from its outer circumference and allows it to almost slip out in some circumstances . Don't be too wary of using a hammer , the lugs will take a reasonable pounding with little effect . Another way is to use a socket of the exact size to fit into the lug's hole and sit onto the end of the bush , use this to drive the bush out using a clamp or portable vyse.
A dremel can be used ,but be aware that if considering drilling the bush out ,that it is made of exceptionally hard steel .
 
How hard can I bash the pin out. I have cut the pin either side of center mount and removed from the side mounts, the pin left in the center mount does not want to budge Any ideas.
Thanks
 

Try to drill the centre out first . The heat may help and the drilled out middle will allow some flexibility to the pin that should allow it to compress inwardly .
Don't bash too hard ! Too hard is about what it takes to break a brick .
 
Hi Ron
Finally managed to cut drill and bash that
pin out no idea where or what it was. No
bushings found. So will purchase correct
hinge pin and a new rocket as this one is
broke. Where do I get the bushes from would
Sparex have them.
Cheers

Sparex probably has them. This is where I bought mine. https://external_link.com/t20-hydraulics/1628-ferguson-tea-ted-tef-z120-ford-2n-8n-9n-rocker-bush-1212003.html
