Genuine OEM #10 heavy series split lock washer (part# 01713) for Tornado carpet extractors including the 98168 Marathon 1200. In stock in Crystal, MN. Call 763-535-0770.
A split lock washer holds a fastener by staying sprung after the joint has settled. This is the #10 heavy series version — thicker section than a standard #10 lock washer, so more spring in the same diameter. Part number 01713 is the genuine OEM part.

Heavy series is a real specification, not a grade of quality. The extra section gives more spring force, which is why it is chosen where a small fastener has to hold against vibration that would defeat a standard washer. Substituting a standard #10 lock washer looks right and gives noticeably less locking force.
Like every lock washer, it is single use. It works by remaining sprung, and one that has been torqued flat has spent its spring — refitting it is exactly the same as fitting a plain washer. If a joint on your machine keeps needing retightening, a reused lock washer from an earlier repair is the most likely reason.
Judge a used one by its step. A fresh split washer has a visible offset where the two ends of the ring sit at different heights. One that has been crushed flat has none, and at #10 size the difference is small enough that it is worth comparing against a new one rather than trusting memory.
Order arrangement matters. The lock washer goes against the nut or the head, with any plain washer between it and the material. Reversed, the washer bites into the material rather than into the fastener and does not lock.
Fit to the correct torque. Over-tightening crushes the spring on installation and gives you the same loose joint you were trying to fix.

What does “heavy series” mean?
A thicker section than a standard lock washer of the same diameter, which gives more spring force. It is chosen where a small fastener has to hold against vibration that would defeat a standard washer, so substituting a standard #10 looks right and locks noticeably less well.
Can I reuse it?
No. It works by staying sprung, and one torqued flat has spent its spring — refitting it is the same as fitting a plain washer. Judge a used one by the step where the two ends of the ring sit at different heights; at #10 size the difference is small enough to be worth comparing against a new one.
