Tracy Gruetzmacher 3 #1 Posted September 30 The only difference between a C-145 hydro and a C-165 hydro is the horse power of the motor. Is that a true statement? The reason I ask is I have a C 145 hydro with a leaky pump. And I know where I can get a C 165 hydro donor that I know the pump is good with no leaks. Would this swap work? 1 Share this post Link to post Share on other sites

oliver2-44 9,743 #3 Posted September 30 Looks like you found a good donor. .Take us along for the swap. Remember with hydraulics, cleanliness is key. 1 Share this post Link to post Share on other sites
daveoman1966 3,751 #4 Posted September 30 Just watch that they are both Eaton power. The odd-ball 1980 C-165 has Sundstrand power. From my spreadsheet: 01-16KS01 1980 C-165 Automatic Kohler K341AS-71803D 16 Sundstrand 90-1173 1 Share this post Link to post Share on other sites
Tracy Gruetzmacher 3 #5 Posted September 30 The C 145 has a Sunstrand and the C 165 has an Eaton. I have been told to break tractor at 4 main bolts and swap entire rear end assembly out. Is this true? 1 Share this post Link to post Share on other sites
pfrederi 17,735 #6 Posted September 30 NO Motion control Linkage setups are different between Sunstrands and Eatons. Share this post Link to post Share on other sites
Ed Kennell 38,162 #7 Posted September 30 Is the C-165 a roller? Much easier to swap engines than unlike hydros. 2 1 Share this post Link to post Share on other sites
Tracy Gruetzmacher 3 #8 Posted September 30 Yes the C 165 is a roller. Hmmm, thanks for info. Share this post Link to post Share on other sites
Tracy Gruetzmacher 3 #9 Posted September 30 The 165 is beat up and the 145 is way nicer so switching rear end assemblies is still what I am thinking. The motion control would come with the rear end assembly if I split at the 4 bolt? Share this post Link to post Share on other sites
pfrederi 17,735 #10 Posted October 2 Take a look at the linkages under the panel ahead of the seat (and forward of the 4 bolt separation point.) They are different. 1 Share this post Link to post Share on other sites
Tracy Gruetzmacher 3 #11 Posted October 3 I did look and they are waaaay different. If u look at my other post about pump shaft seal leak, I have the leak stopped with 518 loctite. So mayhave dodged the swap bullet. Thanks for all the help. Share this post Link to post Share on other sites

Easier to swap the engine, hood, fender pan etc. Share this post Link to post Share on other sites
