I need a straight crankshaft for a 5024 Brick top. What other cranks can I use in this engine? What are the differences in these LB Brick top internal parts?
His engine number is a D-433. Personally I think I would do what his dealer recommends and just replace the shortblock with a good used one, or NOS. A good used one should be easy enough to find in Pennsylvania and no big internal parts disassembly will be required. Just my 2 cents...and really if that hardened steel crank is warped then what else has the delicate cast aluminum parts been subjected to? Those cranks are tough as nails.
I bought a new short block from my dealer for $40.00 so I hope to make the conversion soon.I have the same 5024 Brick top. Love that little mower as it was my grail mower for years. Growing up in the village where I did, my neighbor was the only guy in town with a Lawn Boy. I loved the sound of that mower as a kid in the early '70s. Everyone else had the typical Briggs/Tecumseh powered mowers, but when he would fire his Lawn Boy up, I would watch him mow for quite a while. Hope you're on your way to getting that Brick ready for the yard again!
