Repairing Craftsman 5 hp chipper
Recently we picked up a free older chipper shredder that was in need of a little tender loving care. It was free and could be used to make our own wood chips for the smoker. We got it home and started the job of repairing Craftsman 5 HP chipper.
Finding manuals for the chipper and engine
With a grease rag and flashlight I was able to find model numbers for the Briggs and Stratton as well as the Craftsman model number for the entire unit. It is a Craftsman 247.797853, 5 HP chipper/shredder.
Before I could begin Repairing Craftsman 5 hp chipper the model numbers were needed to see if replacement parts were even available. I was able to quickly find a free PDF version of the owners manual online. With the model number for the Briggs we were able to find repair parts numbers for most everything we needed.
Engine repairs made
The little 5 HP Briggs actually ran when we got it, but it didn’t sound quite right. Upon inspecting the gasoline in the tank it had the slightly sour taste of old gasoline. It would need a tank flushing, and at a minimum, the carburetor bowl cleaned. While taking off the air cleaner assembly it was clear the air cleaner needed replaced. I was able to find an air cleaner and spark plug kit for $6.50. The plug was ok, but was replaced along with the air filter.
After removing the gas tank and carburetor it was easy to tear into the carb. The bowl had varnish buildup from our ethanol gasoline and needed cleaned. The needle looked rough, so I elected to just purchase a carburetor rebuild kit. It was around $10 from Amazon.
The carburetor kit made a world of difference in how this old chipper ran after flushing out the tank and adding fresh ethanol free gasoline.
Chipper shredder blades
To inspect the chipper and shredder blades on this unit I had to tear into it a bit. With a few basic hand tools I was able to inspect our blades. They were beat up but would be fine with a sharpening. If you’re taking on this same job you can still buy replacement blades.After installing my sharp blades I buttoned the unit back up.
Chipper shredder bag
The bag for this chipper shredder was long gone but I had hoped I could catch the chips in a bucket or something similar. Unfortunately I discovered the bag was going to be required, it generates too much wind and the chips were blown out of my bucket, A serviceable replacement bag is available for around $46. If you are good with a sewing machine it would be easy to make one of these with the dimensions listed through my link.
The first chipping job after repairs
The first task for the old chipper was to make some wood chips from a mulberry tree for our smoker. We ended up chipping some hickory and apple wood as well.
