We've been getting a lot of calls about replacemet cranks for the 443R and 236R—the steel ones that just seem to wear out faster than they should in that 500-1000m² range.
It's a 700g steel piece, precision machined, and it basically fits the 443R, 143R, 236R, and 436R models without issue—MOQ is usually 50 units or so, and we check the runout.
What it does is convert that piston motion into rotational power for teh straight metal blade, and it handles torque pretty well for a trimmer mower, though you don't want to use it on anything above 1000m²—it's not built for that.
Most buyers go with the standdard metal finish, but our company can do a suface treatment if you need better corrosion resistance (usually adds 2-3 weeks to lead time).
We usually have stock on these, but the 20-day lead time is typical for a full container—give or take a few days depending on your port.
We typically require a minimum order of 50 units for OEM production. Let us know if you need a smaller batch to start with — we can discuss that.
For an order of 200 pieces, expect around 15-20 working days from order confirmation. This can vary slightly depending on current production load.
Yes, we can supply a material certificate for the steel upon request. We also offer a dimensional inspection report if you need it for your records.
Yes, they fit the 443R, 143R, 236R, and 436R models exactly. All use the same 2-stroke engine crankshaft design, so no modifications are needed.
Each crankshaft is individually wrapped in oiled paper to prevent rust, then packed in sturdy cardboard boxes. For larger orders, we can use wooden crates to ensure safe transport.
