Hey Dan,
The bushings are not meant to be a press fit. They just get stuck over time.
After you get all of them out you will want to clean and polish them
with a piece of crocus cloth or a scotch brite pad. The bushings
should slide in and out easily so when the pump is assembled the o-rings
constantly keep the bushings pressed against the sides of the pump
gears thereby minimizing the amount the gears move back and forth.
This also keeps the gap between the gears and the bushing
to a minimum for better suction in and pressure out. I believe
the bushing are suppose to be able to move freely to compensate
for wear . I think that is why the bushing have a flat on them.
And because the bushings can float the flat keeps them from
spinning in the pump housing bores. But hey that's just
my mechanical though processing of how I think things work.
I don't have any documentation to substantiate any of the above
information, Its just my opinion.
Now for where I get part numbers, I go to the Agco parts book
web site. You will want to use the north American web site so
you can view the parts books. The European site wants you to get a password
from your local dealer. On the north American site look for guest user
on the bottom right side of web page. at guest user click on view books.
from there choose Massey Ferguson, then parts, then tractors,
then compact, then 1120. Be aware that the 1120 has a different
front axle than ours. That is why I also use the White field boss 16
for parts. The White has the same front axle we have. Both
of these tractors were made by Iseki.
Try this link. If this works, look for the browse books on the top left.
If this doesn't work for you, try the other way outlined above.

Also, Check the link below.
TractorData.com - Farm tractors
You can lookup tractors of many manufactures.
My tractor was made in 1978. From what I have found
the TX1300 version I have was made from 1978 to 1981.
Also over here in the colonies these tractors were sold under
the bolens name. Mine is a bolens G154 which is an Iseki TX1300F.
In 1982 Bolens still sold a G152/G154 but it was now an Iseki TX1502/TX1504.
From what I have found 1991 was the last year Bolens sold Iseki tractors under
the Bolens name. I have a PDF of a 1996 Garden way Service seminar
which list the Bolens/Iseki tractors and attachments. I could e-mail
it to you if you want. One of the reasons I know some of this is because
we can't buy new factory Iseki parts in the USA because there are no
Iseki dealers here but there are Massey Ferguson dealers and if I
can come up with a part number under Ferguson they can get
me new parts through Agco who now owns Massey Ferguson.
Its a round about way of finding parts. Ok this has gotten
way to long. It has taken me over two hours to finish this darn post.
I had to stop and go find out why our furnace wasn't working. I worked
11 hours today climbing around one of our CNC lathes at work trying to fix
it and when I get home the house is cold but my wife and son did not
notice the furnace isn't working. I found the furnace ignitor had come lose and wasn't making contact so no spark. Do my post look upside down across the pond?
Ok, this has gotten way way way to long.
Thanks for spending the time on that - really useful stuff. It's not upside down, because I'm across the pond, but I do have to turn the screen sideways to read it!
Thanks for the tips on the bushes, I'll give them a bit of a hone before they go back in. I'm just waiting on the parts to arrive from the website above before I pull it apart again. The oil seal definitely needs changing too.
I'll update in about a week!
