Some time ago I posted on this forum regarding a G1000 FWA Wheatland Diesel that I has rescued from a cattle station. Well I finally removed the heads from the motor, and the internals are not good. I now need to remove the front axle and sump and then the rod bearings so that I can pull the blocks and pistons off together, and then somehow push the pistons out of each block. It's pretty obvious that this motor is going to need a rebore and new pistons, rings etc. I think at least three of them are stuck - one in each block section. I am assuming at this point that the pistons are standard size and most unlikely to be usable again.
I discussed this with a local engineering shop, and they suggested that a rebore and sleeve may be a better option. So I thought I would put this out there and see what you guys think. I have not seen any discussions on sleeving these engines. The parts manuals all list pistons and rings at standard, +20, +40 and +60 sizes.
I have also noticed that the businesses selling aftermarket pistons only list pistons for gas/LPG engines.
So at this point I have two queries
(i) is it better to rebore and sleeve these engines, or rebore and use oversize pistons?
(ii) is it still possible to get pistons for these diesels?
No doubt I will have more queries on this rebuild, as my intention is get it back to a workable tractor in an ex-factory condition.
Thanks in advance
