How Do You Maintain Johnny Jaws?
Weekly maintenance for Johnny Jaws: grease zerks, bolts, airbag check, and the latch adjustment bolt.
Weekly Greasing And Inspection Routine
Keeping Johnny Jaws running on your front-load truck is straightforward. The weekly maintenance routine takes a few minutes and fits right into the truck checks you're already doing on your fleet.
Hit all three grease zerks, make sure the bolts are tight, and look the unit over for any cracks. Check the airbag while you're at it. If the latch indicator isn't popping up when the driver throws his latch, there's an adjustment bolt right on the unit that brings it back into spec. And if that adjustment bolt ever breaks off, guys in the field have welded it right back on without missing a beat.
No special winter prep, no separate lube schedule, no parts that need babying. Joe Ruby walks through what to look for and where to hit it.

Do you guys deal with the same weather we got? In the winter, does it ever seize up?
Never had it. Nope.
You don't lube it up or nothing?
Nope.
Now maintenance on it. We do our weekly maintenance on the truck. Is there any maintenance to keep it up?
The weekly maintenance is to grease it. Hit all three grease zerks. Then tighten the bolts, or make sure the bolts are tight. Make sure there's no cracking going on on the Johnny Jaws and check the airbag for any cracks to make sure that's not going to blow out.
Right here is an adjustment bolt. If he's throwing his latch and the indicator is not popping up, it could be just out of adjustment here. Or if it is in adjustment and that's not popping, this may have broke. I know there's some guys that had the top of it break off, and they just put weld back on it, filled it right back in.
