International Harvester 4510 Skid Loader Category
Original Model: Onan NHCV
The engine and shortblock are no longer available. The original Onan engine had a 1-7/16" diameter shaft on them. You could possibly put a newer OHV engine into this machine, but you would have to add a mounting plate to raise the engine up to the original shaft height. The throttle and choke hookups would both be different and the wiring will be different. If you drive off of the flywheel side, you would have to make an adapter to bolt to the new flywheel so your drive part would bolt up to it.

While we may have sold many engines listed above to be used for a International Harvester 4510 Skid Loader Category, we are NOT claiming these are exact replacements unless the product notes explicitly say so. Many original equipment engines may no longer be in production because of obsolescence or EPA regulations, so in some cases there may not be an exact replacement available. Our intention here is to show that other customers have utilized these in the equipment shown, but may have had to make some modifications to do so. If we know of any required changes, we will list those, however, some adapting during installation should be expected.
