520 Question

[743]

I am loking at a 520 bobcat and it has no engine. It has a hub and a Spline couple sticking out and thats it Like shown on this ebay Idem http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=370018373959&ssPageName=STRK:MEWA:IT&ih=024 The spline is bigger than a chevy drive shaft. So heres my question is there another adaptor or is the crank shaft have a spline end on it?

All the parts should still be available but the only thing that concerns me is you may also need a blower for the oil cooler. This will be very expensive no doubt. If you hook up say a thermo fan i see no reason why you can't get an engine and U-joints and adapter to the pump.
The hub you can see, is that just the drive spline on the hydro pump? If so, you need the adapter like what you showed on e-bay, 2 U-joints plus a few other parts to attach to the engine.

It looks like the guy selling the hub on ebay has parted out a 520 and may have all the parts you need. You should ask him. The 520 had a 19hp Kohler air cooled engine and no oil cooler.

Sorry, The 520 did have a oil cooler for the hydraulic oil so you'll have to see if that's there.

Blower will be spendy! Make sure you factor that in before you buy the machine. I would suspect $5-700 but a call to your dealer would confirm this. You could mount a thermo fan if needed.

I guess for $400 I really can't go to wrong. Heck I wasted more on other things It was just the fact that this spline is bigger then a Chevy driveshaft spline and didn't know if Kohler had that big of a crank or if there was a adaptor.

my 630 is also air cooled the hyd cooler is mounted in front of the engine so the air going into the engine cools the fluid first.....Jeff
