Hello 1545872,

To increase the cut-off pressure of the Bostitch CAP2000P-OF Type 0 Air Compressor. Turn the Red Knob on the part number AB-9415883 Pressure Reducer(Regulator) to the right. to the desired PSI cut-off point. You may have to turn the red lock nut below the knob.

Hi jg2259,
There has been a couple of cases where the contacts in the pressure switch have burnt and prevented the pressure cam from opening the circuit when the pressure reaches its link removed that case the pressure switch has to be replaced.Hope that helps.Good luck.

How do you install new belt

Hi,
Is the new belt the same size as the old belt.They used two different pumps on that compressor.One pump has a small air filter on top of the pump cylinder head and the older pump has it on the piston as the air is drawn from under the piston.which pump do you have?
Tinker

Can you plz give both part#'s to these belts. Thx

The belt number for the OL195 pump is AB-9075047 which is for the first generation pump.The OL197 takes the AB-9075316.
Now the are a bit difficult to get on as they are very tight fitting belts.

How do you change the belt on the bostitch cap60pb-of? I have the one with the filter on top of the cylinder and a model # of 9415905. I cant figure out how to get the belt over the crankshaft. What do I have to remove to replace the belt and in what order. Thanks for any help.

Hi dustyiniowa,
Well if you have one of the many pressure reducers that were faulty on that model compressor you really only need to unscrew the regulator knob assembly and replace it with the new regulator knob assembly that is on the regulator that you bought.If you want to change the whole thing you first have to remove the two pump case half and unscrew the female connector from the regulator body.Be careful though as the manufacture uses a high strength green loctite that might need to be heated a bit to get it off.Then remove the regulator body and reassemble in reverse order.Hope that helps.Good luck.

Hi mcmar,
Make sure the teflon ring is sitting centered on the link removed your top piston cap and torx screw.Be sure to loctite
the screw.Put the bottom of the connecting rod through the top of the cylinder.With one hand hold the cylinder top end down on a soft block of wood and grab the bearing end of the connecting rod with the other.With a rocking motion pull the piston and teflon ring through the top of the cylinder.You should have a tight fit.Hope that helps.Good luck.

Hi wjcj5251,
If I remember right its M5.08 thread. and to remove it ,screw the long bolt that holds the two halfs of the shroud together into the nut and tap on the bolt to get it out of the shroud.Hope that helps.Good luck.

Hi roni,
My understanding is this motor non serviceable and needs to be replace as a unit
Group Motor/Crankcase Part Number: AB-9415925. Hope that helps.Good luck.
Tinker

Anybody know where one could get brushes for this unit? Looks like common brushes to me, I just have a problem buying a group motor/crankcase for $150. when brushes cost $2.

Hello predicta,

The manufacturer does not supply the brushes for the Bostitch CAP2000P-OF Type 0 Air Compressor . The AB-9416744 Group Motor/​Crankcase would have to be ordered.

How do you push that stiff ring in there without breaking it?

Yes, a video on youtube would be awesome. I've destroyed 2 piston rings trying to get them installed. Don't order from link removed. There tech support sucks and their jack you on S&H.

Hi DWFryer64,
Yes its the pressure switch assembly.Bostitch had a number of these units with pressure switch problems.Hope that helps.Good luck.

Thanks Tinker!

Is swapping out the switch fairly straightforward? Anything I need to know about the repair (I'm fairly handy with tools, but this is my first compressor)

My situation is exactly the same as yours. Turns out the threads are completely stripped out of the cylinder where the regulator screw runs in and out.
Apparently the metal is too soft to withstand the pressure against them. the screw threads appear to be intact.
The replacement part is a special order and takes three to four weeks to be shipped.
Ordering the replacement part is probably the only solution. The screw is steel, but the cylinder is non ferrous, probably pot metal. Hopefully the replacement part is better engineered, but I'm still thinking of a possible material that will adhere to the surface of the cylinder, that can be drilled and tapped.
If the replacement part is no different than the original, then, I'm afraid it will just be a matter of time before it strips out again.
The model no. of my compressor is "C-pack 1850 BN, which is not listed anywhere.
I'm hoping that "Cap2000P-of" has parts compatible with my compressor. In fact, I plan to call the Stanley Bostitch people to get more info.
Hope this helps.

the best is Raymon's answere an cheap,all you need is super glue I doubt if I will ever buy any thing from this company again

Hi Guys,
Call Stanley Bostitch and explain your problem to them.They are fully aware of the problems with the stripped knob (we have boxes of them in my shop).There was a quality control problem with these regulator knobs as the threads were not tap to specs.Explain to them that your aware of this problem and like using their products and feel that they should give you a little help by sending you one out at no charge.Be nice and polite and in most cases they will send you one to replace the defective part.These tool companies really do want you to be happy and I now from experience that they will bend over backwards to help.Hope that helps.Good Luck.

There is no such thing as a Bostitch model 1850BN. Look at the bottom of the tank for the model #. It should be a CAP2000P -OF. Disregard the 1850BN designation as it is not the model #. Stanley Bostitch 1-800-556-6696 Parts- 1888-678-7278
