MY 52 started rattling bad yesterday

Postby IHC52 » Sun Apr 30, 2017 12:35 pm

!st time use for the season cutting my lawn. Oil was AOK, water AOK, no issues. 1/2 way through cutting, a squealing/rattling noise came from the front & was a definite drag on the motor. I immediately shut her off, Belts were tight, fan---no slop--oil was clean, Gen. was charging. I started it back up & could tell there was a "Drag" trying to slow the engine down & the rattling quieted a bit but still remained. I did see some water come out from somewhere, but could not pinpoint the spot.

She started hard this AM (drag again) & I have her in my shop. Do these baby's have water pumps ,because that's sure what it sounded like. I'm going to start taking her apart---remove fuel tank etc now & inspect. Just as an FYI engine is running like a top----NO smoke----no hesitation. I replaced the bearing set-up a few yrs ago with one of the more (supposedly) reliable fan set-ups. Fan remains tight w/no slop. Gen was rebuilt about 15 yrs ago. Appreciate any feedback men.

Thanks,
ihc52

Try running the engine briefly with the fan belt loose/removed. Sounds like the fan shaft is seizing. Have you oiled the fan shaft? There is no water pump, thermo-siphon cooling. Not sure what you mean about "replaced the bearing set-up a few yrs ago with one of the more (supposedly) reliable fan set-ups. Fan remains tight w/no slop." A bit more info and/or picture might help on this one. Couple of additional posts will give you access to the manuals available at the top left corner of this page at "QUICK LINKS" tab where you can view/download lots of good information about operating/maintaining your cub.

Hi Stan, poor lingo. The original fan shaft that had bearings in was replaced by this Chinese set-up they sell on these new fan units. I have hood off now , removing belts now----------------------

Trying to paste a pic-------------No Luck, I'm new to this forum. Bottom line------------the JUNK bushing in this Chinese fan assembly (NOT original) just ate itself up. Who rebuilds/exchanges the original fan w/bearing assemblies ??----Thanks
