The older I get the more it turns out my dad is right ........
Picked up a 680ck ( A267BD motor ) a while back , tired old girl but lots of potential . She ran well & never beat on her , oil & coolant mixed one day . Head gasket was not the issue , liner bore seal surfaces failed due to cavitation , electrolysis ya da ya da . All 4 cylinders have had the stuffing beat out of em !
Previous mechanic on this tractor fleeced these ugly bores with a generous coating of silicon ( rtv ) is what I discovered when I pulled her apart . I'll be quite honest gentlemen , I've never pulled an engine liner & what a fight ! Everyone one fought like hell on the way out .....
It gets better ! the folks at my local tractor salvage yard have a " tractor part hotline " and FLOCK ALL in the complete engine / engine block dept. for the J.I.Case A267BD motor .
I'd like to think that I'm more stubborn than an ugly stripper with a new outfit . Heads are off , pistons , rods , counter balance unit are out & I do have a plan so please comment ....
Step 1 : Pull motor & take all ( plastic-gauge ) journal measurements , strip block & have machine shop bore and sleeve block .
Step 2 : Slam a new " in frame " overhaul kit in motor on reassembly
Step 3: "Make The Dirt Fly"
I have some machine shop experience but the local shop asked me if I was providing the "cast sleeves" ? I asked the machinist " do the sleeves have to be made of cast " ?
His reply was " I'm only the machinist , most farmers always provide the sleeves ( one way or another )& they are ALWAYS cast .
Reaction to heat & or water is all that comes to mind when it comes to mixing metals that need to retain shape & water tightness while temperatures vary .
Any comments on this situation gentlemen ? The boy & I should have motor out buy Wednesday night
Always Best Regards
