PTO seal change

[keptenjim]

It looks a heavy casting to me, I imagine it's dowelled and bolted to the rear casting and it will have a recess for a bearing and external seal. Pulling the cover plate off may bring the PTO shaft with it if it's the floating type but it would only need to be pushed back in.

What tractor is it, you should be able to find an exploded diagram on the net.

 

Kubota A-17 Aste. I've scoured the net but can't find any diagrams

Its the 'bearing' aspect that concerns me. Where is/are the bearing/s? Will the bearing come out with the case or stay behind? By removing the cover, is there a chance that I'm going to damage a bearing? The tractor is a grey import so I have to be careful with my spares requirements

 

The bearing is behind that plate, its a "vet chasing a tomcat" or on other words, a ball race. The balls are on a cage and enclosed between an inner and outer bearing face, this page has a good cut away shot 7005-CSUP4 Nachi Precision Ball Bearing Single - BearingBoys.co.uk

 

The entire thing is pressed into a housing (the cover) usually on a tight (interference) fit but some have a circlip to prevent movement. The balls wont fall out unless the bearing is seriously goosed.

 

Taking the cover off isn't going to cause damage its supposed to be removable, having at it with screws and tools could.

 

Parts wise, unless its a particularly old or obsolete machine a decent bearing stockist will be able to cross reference any numbers from the seal or bearing.

 

On scale of "how difficult" it rates a 3/10 on the beginners scale.

3/10? I should manage that then, even being the half-wit that I am! Thanks for that info
