Hi all,
I am working on my JD engine, which partially seized on me last winter, due I suspect to bearing wear, dirty oil, maybe partially plugged oil filter. Anyway I pulled the engine and all is apart.
The kicker is that there is no aftermarket rebuild kit for this engine, (type 4219 GT) which is gas. There is one for the diesel version. Among other things the pistons are different. Nevertheless I have sourced most of what is needed to rebuild it from different suppliers, including a new (used) crank and all the usual bearings, gaskets etc.
I am hung up on what to do regarding pistons, liners and rings. JD does have liner kits available, the problem is the cost, $403 per cylinder and I need 4.
What really floored me was the cost of just a ring kit, $132 per cylinder!
So, what to do?
1 mortgage the house and buy four new liner kits (really a stretch to find that much $$) OR
2 Re-use the old pistons, rings and liners OR
3 Old pistons with new rings
Or maybe something else, new pistons and rings in old liners perhaps. I am not sure what.
I had thought to put new rings on the old pistons and just hone the liners a bit. However I understand that if the old pistons are too worn in the ring grooves this may not be a great approach. I would appreciate insights from anyone with more experience.
