I have a homelite 20av and the chain lube has stopped. Does anyone know the steps to replace it? Thanks

Hi,
Thanks for checking in but I have some bad new for you . This group discusses the American Made Homelites of the '50 through the early '90s so you may not find much help. Here are a couple of links. the second one shows the oil pump which consists of 4 parts and it looks like there is a repair kit listed.

The easiest way to replace the oil pump on that saw is this:

1. Remove decal from side of the saw.
2. Replace entire saw with functional one.
3. Apply decal to replacement saw.

OK, seriously. I have never had the misfortune of taking one of those apart. Most of the saws in that price point use plastic drive gears on the oil pump. Often if you run them out of oil, or a piece of crud gets in there, the pump gears will shear off. You'll have to pull it apart and see what happened. Start by draining the gasoline and oil out of it to prevent a spill once you get into things.
