Briggs & Stratton Intek Series, 19 HP, 540 cc, Single Cylinder Engine

The media could not be loaded. I don’t do many reviews on products, but in this case I will. Because this information may be very useful to someone else that had the same problem or concerns.My 42” inch cut Husqvarna model YTH18524 engine shattered the piston arm cause of the balancer broke and it made the piston rod just explode. The motor was the 18.5HP 33R777-0005-G1 and I was looking for replacing just the parts. But it was a catastrophic failure in the motor. So I was on a hunt for a new motor… come to find out, the 33R777-0005-G1 are discontinued. So now I was upset cause now, I need to find a new Mower now versus a new motor… I was upset to say the least. But I started doing a lot of research on replacing the motor still. From the marketplace, eBay to amazon. Wasn’t sure buying a used motor on marketplace or eBay would been the best idea.. So got on amazon and seen the 19HP 33S877- 0019-G1 Motor. I researched into this motor extensively to make sure all components are compatible with my Husqvarna YTH18524. To my surprise, it was compatible with my mower. So I ordered it.I came fast, earlier than expected. Packaged well. Took the old motor out and dropped the new one in. Note the 19HP 33S877-0019-G1 “DOESN'T HAVE THREAD FOR EXISTING BOLTS” you can either use a threader and cut your own threads or you can get bolts and just bolt it on. The motor mount holes lined up perfectly and bolted on with ease. The electric harness was an exact match so all I had to do was plug and play, and connect the starter wire. Now with my mower it’s not a side exhaust, it’s a front exhaust and I ordered the 532137352 Muffler Kit (Muffler & 692236 Gasket) for Husqvarna and took off the side muffler that comes with the motor and switched with the front muffler and it fits perfectly.Pleased with how easy it was to install and pleased with how it runs. Be sure to add oil to it before starting it. The motors don’t come with the oil in it. So be sure to add oil before starting. As for value. It was well worth buy the motor and replacing that instead of buying a new lawnmower. And the power of the lawnmower was exactly the same as the old motor I took out. Hope this helps someone else out there.

Fit like it was made for it. Nice engine package. You will need to tap 3 holes 9/16-20 if you want to use the same hardware that cane with the Kohler. If not you can use nut and bolt. I tapped and was a perfect fit. Harness is plug and play. Fuel line easy to cut short due to location of included filter and line. Choke is easy peasy. Remove black plastic retainer and Install choke cable into white plastic holder. Clamp down. Put throttle into chock position on the mower. There is an upper thin bracket on the carb side that you bend up to contact the choke U shaped rod on tge carb. Bend the tab up to meet the rod to get the desired choke stroke. Done. No need for extra choke cable like some have done. Put oil in and start. Runs perfectly smooth and quiet. Good deal. Better than spending 5K on a new Bad boy.

I ordered this motor off of Amazon, it came from outdoor powersports, this company has a lot of chop, chop, from masachusets, to Idaho and I had it in 3 days, frontline motor , that you could tell was fresh, was not a motor that had been sitting in a warehouse for 4 yrs, I had did my research, and was putting this in a John Deere la110 mower, fit was perfect no mods at all , I did remove the muffler that came on it, and installed the original one on this motor. rest of the connections very basic, even came with new fuel pump and fuel filter installed, had oil filter on it but no oil in it, I didn't expect it to, just a reminder to not forget this, seeing oil filter on it , kinda makes you think it is full, it isn't.mounting holes lined up perfect, reuse the old mounting bolts, mower works great, runs great , new ones made so poorly, IT made sense to me to repair the old one with new motor, glad I did, it is built better than the new ones unless you spend 10 grand. I highly recommend this motor and this company. I have used it for 5 hours and then changed oil and installed vanguard synthetic in it, have put about 5 more hours on it motor does not use oil, or smoke, and runs very well good torque from it, nice to finally get what you pay for, can't beat briggs power, ran my old one low on oil, won't happen again, was my fault .
