Piston rings

[arctic003]

Hi Folks - it's been a while!

Well it looks like the time has come for me to change the piston rings on my '78 6945.

I was out ploughing yesterday and had to keep one door and the rear window open otherwise the cab was filling up with blue smoke from the crankcase breather

From the manual it looks like a fairly straightforward job - is there anything I should know though before starting work? Am I likely to need anthing other than a set of rings and head and sump gaskets?

Any other pointers, or anything else I should bear in mind? The engine has about 5300 hours if the clock can be believed.

Many thanks

Hi There,

Just so you know I can supply you with those rings should you need them

J-P,

Hmmm...5300 hrs should not be a problem. Might have gone round twice or three times??

If your tractor has been lightly stressed i.e. a lot of work on tickover or very low revs she might need a good workout e.g. rotavating.

Good luck,

p.s. How is the new arrival?

Thanks Dominic, TomZ

I'm not sure, but I think I can get the rings locally - but let's see. Thanks for the offer anyway

Could the clock have gone two or three times round? Maybe four even! I can tell that it has had a lot of hard use over the years, but I don't have the experience to be able to estimate hours

Actually the tractor was smoking a LOT less yesterday than it was the day before. Before that I hadn't used it in a few weeks.
Apart from the experience of the last two days, I haven't found that giving the tractor hard work helps. If I'm doing something heavy, like dragging a spring tyne harrow deeply, the engine just runs hotter and more oil escapes through the breather. I haven't updated the breather or added a second one yet - I have a PET fizzy drink bottle tied on to the breather with electric fence wire to act as a separator. Once or twice a day I stop and pour what has collected back into the engine

Oh and the little one is fine thanks Tom. Getting less little all the time!
