Guys

Can any of you help me? The background:

I friend of mine has a cutter named Toro as he sit upon when he cut the grass. The right hand side Spherical bushing has been wearer and he can no longer use his cutter.

I’ve been searching after that detail and found it on www.psep.biz/store_mower_bearings.htm It has 3 number, the first begins with 12-8789.

The detail is made in USA by Triangle MDG Oshkosh Co Wisconsin. I have tried to find it on a Swedish site but failed.

The Type is Toro Kab P-2 (Made in England)
Nr: 190 243 271
(Homolounge Cemagret)

I have some difficulties when I want to know how much Inch is in cm. For example:
ID = 7/8”
OD= 1 11/16”
LTH/HT= 1.1/4”

The external circle is 16,5 cm
The inner circle is 8,9-9.0 cm

If it had been 1 Inch it should be simple to calculate.

Can anyone tell me what ID, OD and Spherical bushing means: The Spherical bushing is a nearly round metallic ball as will lie in a cradle when it is mounted on the drive axle.
