Honda mower run with no oil, rebuild or not?

I have a Honda HR215K1HXA Masters series lawn mower. I think the engine has seized up. Is it worth it dollar wise to rebuild it???

The mower is about 9 years old and looks to be in good condition. I think the previous owner forgot to put oil back in after an oil change or it drained out the bottom of the engine.

When I bought the mower it started on the first pull but had a very loud clicking/clanking noise immediately on start up. It only ran for about 1 second before it was turned off. Previous owner said it was running/cutting fine when he heard the loud noise and immediately turned it off.

So I get the mower home and ran it for another 1-2 seconds until I turned it off quickly. A few minutes later I try again and I can't turn the engine by pulling the chord. I can rotate the blade CCW about half a turn and pull the chord which follows by a hard stop and a clank.

Then I realize maybe the oil is low and sure enough, doesn't look like there is any in it.

So, anyone rebuilt a mower engine that has previously run with no oil until it seized up? What damage is expected? What's the likely hood it can be rebuilt for a reasonable $ price? Talked with a shop and a new engine GXV-140 engine would cost about $450.

It does leak oil from the bottom of the engine.

I've never tried to rebuild an engine before but considering it if it makes sense... I know itís good model mower, but what would it take to get it running?

Thanks.

'IF' the eng has a'cast
iron' cylinder liner-it is rebuildable-if no'iron' linner '-disposable'
no oil on start up could damage the rod bearig surface.the crankshaft is replaceable,probably a rod also. but an aluminum cylinder wall-(no linner) is 'useless'-threrfore-disposeable

You must disassemble the engine to determine the extent of damage. Personally, I would replace before I rebuild. I do not think the cost will be too different if there is much damaged.

I could be wrong but I do not think the GXV140 engine is being made anymore. Even if it is, $450.00 is TOO much money for that engine. The price of a new replacement engine should about $200.00 or less.

Get the COMPLETE engine number along with the mower number and call businesses, local and internet, to find a replacement.

As far as I'm aware it is discontiuned. I would reccomend a GXV 160, I find the extra power is often usefull, and even here in rip off Britain you can get one for £200.

Alternatively you could get a briggs quantum 4.5-5.5hp, which would be cheaper, and should still be ok, although I don't think they are quite as good.

Thanks for the comments back. I did finally find a little time to disassemble the engine and found a broken rod. Looks like I would need to replace the crank, piston rod, gasket, lower shaft seal at a minimum. As irony would I have it I do have a piston and rod from an older GCV-140 engine I took apart a while back for tinkering purposes.

Questions: I do see/feel 1 or 2 small vertical scratch marks in the cylinder. I have no experience here and don't know what would be acceptable. A while back I heard it is a good idea to hone the cylinder? Should I do this and get new piston rings? Any guidance would be appreciated.

As far as a replacement GCV-160/GXV-160 engine. How would I know if I can bolt it up to the existing frame? Also I need one with a direct drive shaft to reconnect to the hydrostatic transmission. Does Honda make these engines "interchangeable"? I did a quick look around and I can find one with a direct drive. I guess the BBC and cables should be able to swap over.

If memory serves they should be the same, but check it out before you buy.

And hopefully in the future, you will ALWAYS check the oil before starting any small engine. Think of the cost of these repairs as tuition.
