Wood Splitter Shaft Question(s)

nh8260 · Feb 4, 2019

The other day i bought a 20 ton wood splitter from a guy, the motor on it was not the best of condition so i went to Northern Tool and bought a 208cc motor, everything went great till i went to put the pump back together. It has lovejoy connectors in the pump, basically i found that the old motor had a 1.5" long shaft, the new motor has a 2 19/64" shaft, by it being longer i cannot get everything bolted up right. The idea i had was to mark the new shaft at 1.5" and cut it off there and things should go back together correctly, is there another way i have not thought of? I hate to cut the shaft but that extra length will not let me bolt things up nice and snug. If i do have to cut the shaft, are they tapered? I looked at other engines but did not see any that had a 1.5" shaft.

Gonna GUESS the pump is directly mounted to the engine with an open frame that allows access to the coupling?

I used nuts and washers under mine for spacers. Never have used it though. Dont know how long it will last.

they make all sorts of adapters, but can't remember where i saw them. keep searching and you'll find them.

Had the same problem on my 27 ton splitter. Engine quit and needed a new Chinese engine. Could only find same engine with a longer shaft. Took the metal saw to it and haven't had any problems after five years of heavy use. Kept the old engine for spare parts if needed. Haven't needed any yet.

Once you chop off the crankshaft you'll find that the adapter won't bolt to the engine block. Bolt holes are all in the wrong place and not enough meat to drill new ones.

Instead get the right adapter frame. Tractor Supply has them. Then you won't need to cut the shaft.

Surplus Center? Northern Tool?

If you expect the coupling to last it needs to be aligned to .005 or better. The C-frame adapter on the original engine will do that for you.

You and Glen SW Wi can't both be right. You'd have to see the unit first.
