    Considering whether it is worth attempting reconditioning above engine in our workshop. The engine has run a big end.

    Most of it looks doable and would send the head away etc, but reading the workshop manual it goes through the procedure for reaming the small ends. I don't have the necessary reaming tools or knowledge to ream them out. With modern manufacturing techniques, will the small end bushes be supplied at sufficient precision not to need reaming or do they still need reaming out after fitting? I don't recall reaming the small ends when I rebuilt the Lambo engine two years ago. Just fitted new ones and they seemed OK.

    Any other difficulties or peculiarities likely to be encountered?

    Just asking before I rave it apart. Tempted to just take the offending big end off, emery the journal and fit new shells and leave it at that like we did on the diesel which ran for many more years on light saw bench duties.

    Thanks.
     
  2. If you have engine works near by they will ream the offending bushes for you im sure

    A tvo engine will be under a lot less stress than the equivalent diesel, so emerying the journal may do.

    what id be inclined to do, is remove the head and the offending piston and rod, have the engine upside down with the sump off and clean the journal up, get it down to what you think it needs to be, then trial fit the shells with the rod fitted upside down, ie sticking up out the sump. Given a bit of patience you will nearly get it bang on, a bit slacker will be better than it being tight

    they were not built to very tight tolerances when new, like a lot of engines of the time

    All doable in the workshop, what have got to loose?
    Get the new shells to float from side to side on the clean (no old shell left stuck to the journal or it will pick again) journal with the cap torqued up tight. Check oil pressure after starting especially when hot.
    If it does need a conrod do as suggested above.
    Might be worth checking all the shells as the oil pressure probably dropped while running.

    Very enjoyable, little engines .....

    For price of shells id fit an entire set, a micrometer will be your friend here, measure a good journal and use that as a reference to bring the bad one down to tolerance. Engine layed on its side on the bench will be easier than lay under it getting dripped on by 50 year old oil

    Yes they come in sets now, I hadn't thought of that ............
    He should see the white metal from the shell stuck to the journal, hopefully.

    Thanks. I'll take all the big end shells off, inspect and measure then go from there. Was hoping to get away without too much intervention. It's a friends tractor and he doesn't do much with it, but just wants it running again.

    If it was mine I'd probably strip it right down and do a full refurb. I'd probably have changed the oil as well!

    Good plan ......
    Let us know how you get on ........
    Might be worth checking the drive to the oil pump and the pump itself for excessive internal wear.

    I suspect most of the shells, big end and mains will be showing the brass/copper and will need doing. All the ones I have had apart have been like this and yet they still ran well with no knocking etc.
    One diesel, I got away with a light emery on the crank and new shells, there was no scoring on the journals and it was on max undersize anyway.
    As above any machine shop can ream the little end bushes for you, if needed. I haven't replaced any in any of the engines I have rebuilt.
    Simple easy to rebuild engine, oil pressure is normally 50 cold and will drop to virtually 0-15psi hot.
    If you do go for a rebuild I would shy away from Agriline Gaskets as in my experience none of them fit!!

    Same applies to most of thier engine parts as well, from previous experience of them!!!

    Always had good stuff from EMMARK UK for perkins and other engines, DB stuff i now tend to get from Barcley Williams

    0-15psi when hot, love that ...........
    Nothing like a good wide tolerance ......
    :cool:

    Ha ha, t'is true!!! Some of the boys I plough with show almost 0 on the gauge when hot and yet they are fine, mine shows around 10-15psi and is smooth as silk!
    It does help to have the right oil in them mind.

    Chap at Gardners told me "quantities more important than pressure".

    That's home of the 180, or a different Gardner?
    We never check oil pumps for flow, funny enough ........

    Back in the distant past I worked for a transport company and we had the 180 Gardner in our Foden trucks, we also had a few with the Foden 2 Stroke.
