JCB 3CX 1982
Posted: Wed Feb 06, 2013 12:46 pm
Only just joined this site desperately need some advice, so in hope someone can help here goes.
I have a JCB 3CX 1982 it breathes bad, I have rebuilt engines before many years ago but not like this.
I was advised wrongly and told that I could do the piston rings same as any other engine in situ.
So I proceeded, now find the pistons won't come out of the top the big end journal stops on the liner.
Now I don't mind if I have to put in new liners and the pistons and liners come out together
And of course go back together the same way,
However, after taking more advice I find I might still have a problem, because the person giving me advice said he had never done one like that only taken them out of the bottom, engine out.
His concern was that the big end journal might still not pass the cylinder wall, as the liner is very thin.
I thanked him very much for he observation and being truthful, unlike the the person I took notice of in the first place
and had no idea what he was talking about.
So hear I am can the job be done in situ or is it engine out?
Happy Days to all, although I'm not having one at the moment
