General TR Oil Pressure Gauge - Test

[RJS]

Hi,

I plan to remove my oil pressure gauge for cleaning (66' TR4A). While it's out, I'd like to test it for accuracy. Any good DIY ideas on how I can do this? I tried some searches but, came up empty

you could always connect it in parallel eith a known acurate pressure gauge.

Connect it to a tire of known psi?? You might have to McGyver the connections…

Humm. That has possibilities Mike. I have a portable air pump which has an air line with a schaeder valve on one end and a quick couple on the other. I could use a donut spare tire which are usually inflated to 65psi

Mezy, yours is interesting too. HF has a $30 oil pressure gauge kit I could try and plumb-in.

I think my biggest challenge was finding a method of generating pressure

Any other ideas welcome.

Tee off the feed pipe feeding the original gauge and fit a gauge to each pipe, if the two gauges read the same pressure they cant both be wrong.
failing that try a foot pump with a gauge on it and see how the two gauges compare.

Bingo! It may be a couple weeks before I can get to this but will definitely circle back and advise how I made out

So complicated...I've always just used the rubber nipple on an air hose. But it sounds like you don't have a compressor?

 

[RJS]

You know, maybe this is just the excuse I need to buy a compressor! Then I could do a leak down test as well!

You can bet I'll be online looking tonight

Next to a screw driver and socket set...an air compressor is the next "must have" tool for the shop! You will never regret getting one. My wife even uses it to clean the dogs off before they go in the house, LOL.

I think I just used one of those hand pumps.

I took 2 oil gauges and used a T fitting to check out oil gauge pressure and calibration when driving. It worked fine. The only problem was getting some of the brass fittings for lines and fittings. I actually mounted them with 2 hole gauge holder and drove around. I found one of my gauges read very weak and no gauge read too high. All the gauges even the new ones seem to have 2inch diameter, so you can put a new gauge next to an old one.

Ed, I like it. That's a very neat test rig. A few cheap parts does the trick.

Thanks
