This replacement hardware is a high quality item that is specially manufactured for use on Bostitch air compressors. It is an authentic screw that is used to secure the conrod cover to the connecting rod. Please note this durable metal torx screw is sold individually.
This is for a small, pancake air compressor used to drive a nail gun.
On disassembly, take photo or do drawing to show where parts go, especially reeds in the head..
Assemble new piston parts, use thread lock on torx screw.
Pass connecting rod up and through new cylinder barrel with connecting rod sticking out the end
... Read morewithout the flange. Then hold on flat work surface with piston end down. Stiff piston ring is hard to bend so it will go into cylinder. I put some WD40 on the cylinder to make it easier. push down on cylinder while rocking piston a little until piston ring compresses and piston slides into cylinder. Ring should be concave toward cylinder head.
Assemble piston, connecting rod and cylinder into compressor through the cylinder frame, lightly tap connecting rod onto bearing. Don\'t let piston slide out of cylinder barrel.
Fix connecting rod to bearing with connecting rod clamping screw, thread lock would be good here too.
Install fan onto crankshaft with socket head screw.
Assemble cylinder head parts, taking care to keep reeds in proper place. Use your photo to make sure you get things right. Use new gaskets. Head parts and gaskets form several layers. While holding layered parts together, install on compressor with cylinder head bolts. Two inside nuts are captive in frame, outside nuts require 10mm box wrench to tighten. Install cylinder-to-tank tube and tighten. Run compressor briefly (keeping body, fingers, etc. away from the fan and connecting rod in case something comes loose) and see that pressure starts to build. If so, reassemble cover halves using the long bolts and screws. You will have to take the hose connection off to get one cover half on so release the pressure in the tank if any. Job done. Would have taken less time, but doubted whether reeds stayed in place and took head apart again. Also make sure you order all gaskets and parts you\'ll need up front. I didn\'t and it cost me more for shipping. ereplacementParts was fast on the orders and had the right parts. When a piston lets go, it is best to replace all the parts from connecting rod to piston cover and likely the cylinder too as it gets scored from the piston without ring banging around. Doesn\'t take much banging to do it.

Control rod and piston head disintegrated causing the drive belt to break. Second time this has happened since buying the compressor.
1. Removed the plastic housing surrounding the motor an compressor manifold.
2. Removed the broken Control Rod remains of the Conrod Cover (piston head) and inspected the piston well. Had some dents in there but it was still serviceable so I didn\'t replace it.
3. Assembled the conrod and conrod cover and seal then slid it int
... Read moreo the piston housing. Had to use a small screw driver to bend the flexible seal attached it to just enough to allow it to slip in.
4. Reattached the conrod assembly to the motor wheel and tightened it all down.
5. Spent the rest of the hour attempting to get the new drive belt on. That is a PITA but it can be done, don\'t give up. You will need three hands to do it but a good screw driver in the right place helps keep the belt on the track long enough to get it all the way on. Make sure it is in the center of the wheels before you test it\'s operation.
6. Tested the repair and tank operations satisfactorily then reassembled the plastic housing to complete the job.
Replaced cover, connecting rod, piston ring, cylinder and torx screw. Put the piston and rod in the cylinder and connect the connecting rod. By replacing these parts it fixed the problem.

Burned off the timing belt and damaged the piston ring during repair.
I first replaced the timing belt and damaged the piston ring (rubber). I had to go on internet several times to complete repair. There are (weird)long bolts through the covering. There is a reverse thread bolt on the fan. There is a torx bolt holding the piston ring cover on. Had to heat the piston ring crank shaft with a torch to get the
... Read more torx bolt out. Couldn\'t get it out with an impact driver. The new piston ring is hard to get back in place. You need to premold the new ring and slide the piston in at an angle in to the cylinder or you will never get it back in. There are two small plates of steel in the compressor head that keep falling out and getting out of position. Getting the timing belt on is difficult too. Bostitch Model CAP2000P-OF
