Thread: Governor repairs

I have an old Autopress Manual covering Series 1 and 2. It has a small section on the governor (mainly concerned with installation), which I can probably scan and email to you if you PM your email. It does show that front of the governor has a ball bearing race and a seal. These should be removable by removing the pulley and the front cover, and taking them to a bearing supplier should raise replacements.

I've got an old IBC ESCA catalogue, and the seal is listed as P3281.Any seal shop should be familiar with this number.The L/R part no.is 261573. W.
PS. I know nothing about governors and this may not be what you're talking about.

Thanks John (PM sent) and B.S.F. Nut.

The seal behind the pulley shouldn't be too big a problem but there must be seals where the shaft comes out the side of the body. The worry is that the unit has to be stripped down to get to this area to find out whether it's just an O-ring or a lip seal.

Any clues as to who would have repaired/serviced these governors back when they were more common.
Thinking about it I have to visit a diesel specialist later in the week relating to a problem with the wife's car, I'll ask them and see what they have to say.

From what I remember its similar internally to the works of the CAV pump of the diesel of the era, a diesel shop should be able to sort it for you..

Similar governors were used on petrol engined tractors of the same era Ferguson TEA20?), and some inquiries (starting with tractor dealers or mechanics) should lead to someone (perhaps retired) who can help in most country towns.

If you go to a place that does CNC machining , they will make a new pulley for you . Shop around for a good price . Draw up a good drawing ( takes you back to secondary school days ! ) of the dimensions you need etc, so they can punch the numbers into the machine. It will probably be a "B" section pulley .

Most of the fees are in setting up the machine . Aluminium may be a option too , because you won't be using it 24/7 .

Thanks Guys,

I'm off to the Lake Goldsmith Steam Rally at the weekend, I'll see if I can find someone who can help.

I found time at the weekend to get the governor on the workbench.

The seal behind the pulley is the culprit. It's an original leather one which isn't quite holding the oil in (just slows the flow down a bit).
The input and output shafts don't appear to be leaking so I'll just replace the seal with a modern one and get onto making a replacement pulley.

I've attached a picture of the seal & the cracked pulley.
