gt14rider 1,255 #1 Posted 12 hours ago (edited) Hi all , got a question. Working on a 1972 charger 12 with a sunstrand 90 - 1136 hydro gear. The tractor sat for 30 + years . I drained atf ,the atf was dark, but no shinny parts in the pan. New atf, 1410 filter, service all the ports , checked springs, replaced all O rings, checked valves ( forward and reverse ), springs look good, no nicks or burrs . Took a red wh filter off, so it's been a while since last service Question is how to get some atf up in the top of pump. Don't want to dry start if possible. What do you guys think 🤔 Thanks Tim Edited 9 hours ago by gt14rider Pics Share this post Link to post Share on other sites

gt14rider 1,255 #4 Posted 11 hours ago (edited) Thanks Paul, added some atf, tryed to fill others ports but didn't seem to take much, I can just hear those brass slippers and pump grinding on a dry start.

rmaynard 17,436 #5 Posted 10 hours ago The transmission holds 4 quarts. How much have you gotten in? Turn things by hand at first. 1 Share this post Link to post Share on other sites
sqrlgtr 3,320 #6 Posted 6 hours ago Following with interest got a 73 14hp NoName with same Sunstrand. The ol Kohler K321 was pretty tired when I pilled it under the shed but the Trans seemed stout and thought about a 18hp vanguard repower later on. Please keep us informed on your progress.

I believe (I could be wrong) that you have the 8-pinion diff as opposed to the 12 hp that had the 10-pinion L/S. All are good IMO though 1 Share this post Link to post Share on other sites
