Small weight on drive pawl?

Small weight on drive pawl?

PostBy: daluds On: Tue Nov 24, 2009 10:05 pm

Hello,

The drive pawl on my DF520 gets oil inside of the hole where the mounting bolt goes through, and it prevents it from going down fast enough to engage with the gears. I keep cleaning the oil out, but it keeps getting into the hole. I put a small weight on the pawl to make sure it goes down even when it gets oil in the bolt hole so the fire doesn't go out. Will this cause any problems?

Thanks,

Dave

From what I know, the only purpose of the oil is to minimize the noise of the pawl/gears. It would seem that the extra weight that you added shouldn't contribute to any extra wear of the gears. It does seem strange that the oil is hanging up the pawl. What kind of oil are you using for the ratchet? It sound like it may be too high.

I was having this same issue off and on since I installed my DF520 last year. I think that my issue was caused by having too much oil in the bowl / tray under the gear. The last time took the pawl assembly apart to clean the pawl and bolt I used a rag to absorb the excess oil and left just enough so that the just the top of teeth on the gear ran through the oil. I haven’t had an issue since.

Sounds like The oil is to heavy use a lighter weight oil Have you checked and seen if the bolt that goes threw the Paw might be to tight stopping it from going up down easily .
Also check and see if the edge of the paw is rounded if so run a file across it to taper it up make it even .
