Question about Craftsman Air Tools & Compressors

Open Question

I am rebuilding a model 919.166330 Craftsman air compressor. The pump has one broken rod with the other cylinder damaged. I plan to repair both cylinders with a rod, sleeve, and piston kit. In removing the rods from the crankshaft I noticed a spacer that fits between the rod bearings on the crankshaft. Does that spacer come with the kits? And whwere can I get a repair manual that has assembly information such as torque specifications for the head bolts and the nut on the end of the crankshaft?

SOURCE: air compressor won't run

Don't run it with the head off! the cylinder will just up and down with the piston and ruin the seals again. I have three Craftsman compressors in my shop and I've torn them all down at least twice. Rather than pay for the kit, I went to NAPA and got a roll of cork gasket material and made my own seals. They don't last as long but they work great.

I'd be willing to bet your seal it just too tight. I made this mistake the first time around too. it's not a very good design as the piston tilts through the stroke. I would try putting a light coat of heavy weight oil on the cylinder wall and move the piston by hand to lube the seal.

SOURCE: I need to replace the connecting rod,cylinder

Your compressor is made by Porter Cable. You can use sears parts or takes your old parts to a local Dewalt service center and they will match them up with replacements. You can save some money on the bearing by using a generic. Universal bearing number will be found on the dust shield. Most likely the sears part numbers will be the same as porter cable. Dewalt service center will help you with other questions and or instructions. Good Luck!

SOURCE: wont build pressure after rebuild

check valve plate and gasket for anything broken, also when you installed the piston into the cylinder did you push it up from the bottom? if the sealing ring is installed with it folded down towards the crankshaft will allow air to blowby, it needs to be facing up to pump correctly.

SOURCE: how to remove crankshaft for campbell hausfeld compressor

I assume you have removed the valve head-valve plate-cylinder assembly from the base and pistons. Remove the four bolts holding the bearing cap assembly on one side of the crankcase and remove the cap. You have to pull on the crank to get the crank bearing out of the opposite side of the crankcase. Move the crank forward and turn it until the rear bearing will clear the crankcase and the whole thing will tilt and come out the top. Campbell sells the entire crank, con rods, pistons & rings as an assembly under part number VT040600AJ. This is the best way to go as they don't have con rods to go on the crank if you were to get the journals turned down. NOTE: During reassembly, the bottoms of the cylinders have a taper so you don't need a ring compressor to get the pistons in the cylinders. Just be sure the oil rings are in properly before pushing the cylinder all the way down. The thin oil scrapper rings have a tendency to fold over and get caught between the piston and cylinder.

Why won't it pump up past 40#?

If you don't have any air leaks, the cylinder head gasket is probably bad on the pump. Easy fix for less than $10. you can get the parts you need here: or For around $50 you can get the whole rebuild kit.

Compressor will only hold 20 lbs and looking for some troubleshooting ideas

First check for obvious air leaks:
1. The drain valve on the bottom of the tank.
2. The air hose, both end connectors and the length of the air hose.
3. The air pump, where the line comes out of the pump and where it goes into the tank.
A spray bottle with soapy water works well for this. Sprayed on these areas, look for bubbles indicating a leak. If the motor/air pump is hot make sure the bubbles are not from the solution boiling away.
If these check out, you may have a damaged valve plate or piston/cylinder assenbly. Damage to either will not let the pump move enough air to fill your tank. To check these you have to remove the pump head. The check valve(s) are on a plate directly under the head. Check that the reed(s) are not chipped, cracked or broken off. They have to be in perfect condition to seal the incoming and outgoing air holes so air can be compressed enough to fill the tank. If OK, check the piston and cylinder. They have to be in very good condition to compress the air also. Some times the ring(s) around the piston get damaged and won't seal to the cylinder well. If any of these are damaged you'll have to replace them to get a good seal so air can be compressed and forced into the tank.

I am replacing the cylinder sleeve and compression ring on my Craftsman air compressor model 919165020. Searspartsdirect says that I need two compression rings. Is this right? My compressor only had one... This is the exploded view that I used.

67 head 65 gasket 64 reed valve plate 63 ring,this one goes under the reed valve plate 62 screw that goes thru the 61 piston 60is a ring that sets on the top of the connecting rod screw the piston with the ring into the top of the connecting rod then take the connecting rod end cap off and cover the studs with some rubber tubing.This will protect the crankshaft when you push connecting rod and piston assembly in to the sleeve that is seated in the block.The ring should be flexible enough to push into the sleeve,if not a bit of oil should help.Guide the connecting rod on to the the crank shaft.I hope this helps and thank you for using

2060p only pumps 3 to 4 lbs . will not come up to pressure. reed valve looks good. unit is approx. 2 yrs old its been used for pumping tires and small air nailer home use only. any suggestions as to what...

You will need to check the cylinder for scarring (deep vertical grooves or depressions in the cylinder) and also the piston rings for damage. Sometimes you need to shine a flashlight behind the piston and look down the cylinder to see if there is any wear. If you are only getting 3-4 lbs of pressure your piston is not pumping therefore I would think that the air is just blowing by the piston. Also check your connecting rod and wrist pin. Sometimes the bearing will blow out and not make the rod go completely up and down. Does the motor sound like it is bogging down at all? Make sure you drain all oil and remove the crankcase cover to inspect for any damage. Post back with any questions, I will monitor this post.

I have a craftsman 6.5 60 gal horz compressor.

i have the same piece of junk, iv rebuilt it 3 times in the past 5 years always a piston rod snapped and then it was running on only one. they are built like ****. anyhow I finely got smart and bought a cast iron pump thats not only quieter but puts out twice the volume of air in half the time. it took some work but it was well worth it costing under 200.00. the rebuild kit from sears will cost over 100 and it wont last. the one from sears is a direct drive pump and you will be told no one makes a direct bolt on but all it takes is cutting the aluminum housing away from the motor and welding a pin or bolt to the end of the shaft and putting a pully on it, you will also have to turn the motor to the side but let me tell you this was the best move i ever made. you can pick I bought my new pump from a place called heavy dudy air in ga. 877-447-2485

Craftsman 5 hp 30 Gal Won't build to more than 50/60 PSi

Most oilless compressors suffer from a short lifespan of the cylinder and piston ring. Unplug the unit and remove the cover to expose the cylinder and rod. Move piston to topmost position and examine the condition of the cylinder. If you see scratches or worn areas close to the top of the cyl. then most likely will need rebuild kit. (Not expensive) If cylinder looks good, remove the head and check the reed valves for debris or broken reed. Reed valve plate is also available as part with gaskets. To extend the life of an oilless compressor try not to use it in dusty or sandy areas as the bottom of the unit is open and tends to **** dirt into cylinder. Good Luck.
