I bought this unit last year. Worked great for sprinkler blowouts. Then stopped working. Will start up for a short minute or two then bog down and die with ATF blowing out two relief ports.

Attached is a few photos I’ve been uploading to try and figure out what’s wrong.

Any advice/input would be seriously appreciated.

Helpppppp

Hello all, I thought I'd post my problem here in hopes someone can enlighten me. It's a Fortress 10 gaL 175psi compressor from Harbor Freight. We've owned it for over a year.

Recently went to use our compressor that hadn't been used in a month or two. It powers on and runs, but all of the air pushes straight out through the circled hole in the pictured fitting instead of pressurizing. There's no moisture in the tank, as I checked with the bleeder valve underneath, and it has held at the pictured pressure since last used.

Any advice would be greatly appreciated, as the alternative is buying a new part without knowing if it will fix the issue.

I removed the flywheel and opened up the crankcase/bearing area. 28 individual needle rollers fell out onto the crankcase floor.

The important part is that the rollers were already out BEFORE I disconnected either piston connecting rod from the crankshaft. So they did not fall out because I removed the rods/

I also inspected both connecting rods, and I don't see any needle rollers/bearings in the big ends. They appear to be a simple rod/crank arrangement.

Here's the part that's confusing me:

• 28 individual loose needle rollers
• They are not in a cage
• They were already loose in the crankcase before I disconnected the rods
• The connecting rods don't appear to contain any needle rollers
• When I put the crankshaft into the far/end crankshaft bearing without the rollers, there is noticeable up/down/radial play
• When I put the 28 rollers into that bearing area around the crankshaft journal, the play is largely eliminated

So I'm thinking these may be the loose rollers from one of the crankshaft needle bearings, but I want to verify this before I reassemble anything.

The Campbell Hausfeld parts diagrams are confusing because they list needle bearings such as ST051100AV, but replacement listings appear to show a complete/caged bearing, whereas what came out of my pump were individual loose rollers.

Does anyone have experience with the VT510702JY / VT558704 crankshaft bearing setup?

I need to replace a small compressor for DIY, residential personal use like filling up my car tires, etc. Both of these are similarly priced but the Kobalt comes from Lowe's with a one year guarantee (through the manufacturer) and the Fortress comes from Harbor Freight with a 90-day guarantee. Does anyone have experience with either of these compressors? How long have you owned it and how often do you use it? Would you buy it again? Thanks.

I couldn't get a tight seal after 2 attempts, so staring wondering if maybe the tube is actually 6mm. I think this is the case.

Whoever put the tube on last time used a fuck ton of plumbers tape to get it to "seal," it was leaking tho so obviously didn't work very well.

I ordered some 6mm sleeves, but need to get this thing running before they get here tomorrow afternoon if at all possible.

Anyone every got this type of thing to "work," any tips?

I just got Thai tank secound hand it’s a 21 gallon I got a tiny camera to see the inside I have run hot water threw it to get the rust out this is what the insides looks like will I be okay to use it

My hose is getting so stiff it is very hard to coil, is there there anything I can put on it to soften it?

I just got this old air compressor I’m working on for a project I opened the engine housing and there are cracks at the back I’ve never worked on a air compressor but I’ve worked on engines I don’t think This will be okay but I want to check before I throw it away

cual creen que es el compresor de aire mas pequeño que se puede comprar hablando en litros , hp y precio, para empezar, mas que nada para usarlo con un tornador.

Tested out the pump-up calculator on AirCompDX today. Really straight forward ,you just record your time to pressure, drop in the numbers, and get your true CFM output instantly. Having a clean interface that eliminates the math makes regular health checks on shop compressors way more practical. Definitely worth bookmarking if you do your own maintenance and troubleshooting.

Switched from 460 to 230 and I need to have a higher amperage overpaid relay now. Elgi wants $700 for it, where would I find one from Siemens directly?

After not using it for a couple if weeks i went to start it and all it does is buzz, i replaced the starter cap which is a cd60 240vac 150uf, after fitting it i went to start the compressor and it buzzed again and the cap blew up, the belt mives easily so nothing is locked up.

Any ideas whats wrong please

I ended up buying a 1989 campbell hausfeld vt558704 at a garage sale for 175 bucks. Before this I knew nothing about air compressors and pressure vessel safety so I judged the book by its cover when I bought it with the exterior looking pretty decent. My buddy did all the electrical at my house for free. I put a borescope in it and the tank is not safe. A new tank goes for just under a grand, which is about the price of a whole new compressor with motor and all. But my motor is cast iron and low rpm, way heavier duty than the newer ones. Do you think I should just suck it up and buy a new tank for $930? My motor and pump seem to be in good shape still.

the transfer hose has a leak so I am replacing it, the pressure regulator knob was stuck, and I got that freed up. I need to pull the drain as that seems to be plugged, anything else I should check? it did run and shut off at proper pressure, just looks to have been sitting for a while. would it be good to open the plugs and add sealant to the tank to avoid corrosion?

Hi team what are your thoughts on these compressors?
Would you buy them over an atlas or a Chicago ?

I have never seen this done before.. I buy stuff from auctions and when something isn't getting bids, I buy it for a buck, then I figure out what to do with it,,, I have a few old 30 to 35 gallon tanks laying around, I got several radiators for a buck each and a compressor head for 4 bucks.. I decided to try an all in one unit to dry the air by chilling it before going into the tank. So I run it through the automobile radiator first then through a water trap mounted as low as possible, then into the tank. This should eliminate most of the water in the tank.. From the tank it goes through a water trap converted to use a desiccant, then a regulator with another water trap.. It seems to work but I have only tested it for a couple hours. it is set up so I can add 2 more steps if needed.. 1 a circulating pump for the radiator, and an electric fan I have 2 (also a buck each).. would there be a market for these or a partial DIY kit??

Was wondering if the great people of this group could tell me what model this compressor is. Found it in the father in laws garage next to big 100 gallon upright tank BIL wanted to scrap it. Any idea on horsepower required? Cfm?

Hi all,

A few years back my father got an Ingersoll rand SSR M30 compresor for a bargain.

Didn't got the chance to use it as we really had no the need for it, but now we are trying to do some sand blasting on our car projects and the current compressor can't keep up.

I haven't tried yet to start the ingresoll rand as my current power supply from the grid isn't capable or suppling 30 kw of power, hence the my question:

Currently the compressor uses a 30wk 2800 rpm motor, could i replace the motor with a smaller one and adjust the belt drive accordingly?

My plan is to install a 15kw 2800 rpm motor as i have it on my hands and put a smaller pulley on it than the original one, so that the RPM of the compressor would drop to about half.

Could this be an option ? Of course i would expect a loss of air supply and efficiency but i really don't need that much air anyways, even a quarter of the original air supply would be enough for me

TIA!
