ricksrj58 273 #1 Posted June 27, 2014 a coworker has a 416 hydro that made a knocking noise in the engine he took it to a shady mechainic-he was told it was too much work to repair it wasnt worth it. he brought the tractor home it sat for 4 years with NO oil or plugs in it some mice made a home out of the engine compartment. I've never work on a hydro tranny or an onan engine...how expensive might this be to rebuild-would it even be worth rebuilding-would it be cheaper for him to just replace the tractor?? Any advice or thoughts would be a big help... Share this post Link to post Share on other sites
Forest Road 594 #2 Posted June 27, 2014 As for the Onan. I'd use it for a boat anchor. The tranny if its sealed and full should be fine. I'd change the filter and oil. Use a 12-16 hp kohler or whatever engine is available. Plenty of guys here have bought harbor freight Honda knockoff motors and enjoyed them. Certainly worth a shot.

ericj 1,576 #3 Posted June 28, 2014 you have to do a compression check to see what actually see what broke or didn't then decide if the motor is repairable the hydro should still be good. i just reread original post is the motor locked up or does it spin over. were in pa are you located might be able to help, or take it off your hands what ever you want to do. send me a pm eric j Share this post Link to post Share on other sites
ricksrj58 273 #4 Posted June 28, 2014 well he dropped it off at my house and did not take long to find out both rods are broken,the pistons moved freely with my fingertip and no noise when i spin the crank.looks like i just got a new horse for my stable. 1 Share this post Link to post Share on other sites
Sparky-(Admin) 19,589 #5 Posted June 28, 2014 I vote you re-power it and not re-build the original motor. Mike......... Share this post Link to post Share on other sites
richmondred01 2,208 #6 Posted June 29, 2014 225 hours. Drop it right in new coil, new starter runs perfect. Removed from a 416. Wiring harness attached plug it right up. PM if interested. Share this post Link to post Share on other sites

Desko 552 #8 Posted June 30, 2014 I vote to replace the rods as that would be cheaper than a new engine. Mic everything and see if its within spec then rebuild. 1 Share this post Link to post Share on other sites
546cowboy 301 #9 Posted June 30, 2014 Looks like an easy choice if richmondred01 is willing to make a trip worth your while. If yours has two broken rods that is not all you'll need. Last time I checked rods were about $80 ea. and I bet you'll need to at least have to turn that crank plus a full gasket set runs about $150. The costs just keep going up when you open an Onan.

Forest Road 594 #10 Posted June 30, 2014 X2 for 546Cowboy! It could easily run $500+ to rebuild an Onan. Share this post Link to post Share on other sites

boovuc 1,090 #16 Posted December 31, 2014 Sounds good, Desko. The tractor itself looked fine. Glad you repowered it! Share this post Link to post Share on other sites
Desko 552 #17 Posted December 31, 2014 Sounds good, Desko. The tractor itself looked fine. Glad you repowered it! No so much a repower just a bigger onan as i love em briggs vanguards are expensive and i wanted to keep it somewhat original the wiring is like mint no burn or nothing clean white plastic im torn about selling if i will probably not i might give it away on the forum i dont see me needing several tractors my work horse with the p216 and 8 pinion diff and the D160 is all i need and the pictures dont do it justice it accutaly really nice clean and waxed Share this post Link to post Share on other sites
ericj 1,576 #18 Posted December 31, 2014 well if you want to give it away i'll take it off your hand, don't really need it but it would look good in my collection eric j Share this post Link to post Share on other sites
rustyoldjunk 127 #19 Posted December 31, 2014 The tractor looks like it was well worth taking care of the engine issues and I even see the hard to find cast iron front wheel weights ! Share this post Link to post Share on other sites

Desko 552 #22 Posted January 2, 2015 Yes save them when you can and i didnt think $200 was bad everything in the motor was usable other than block crank and rods which all of that other stuff i had so i pieced it together and went and haven't looked back othe f than the governor being wayyy out of adjustment but it got it were it needs to be after a little reading Share this post Link to post Share on other sites
