Hey Guys - And Bob!
Got a question. I build 5hp racing engines for kart racing. We use a hydraulic dyno for testing the engines. When I built my dyno I talked to the guys at Haldex Barnes and they recommended I use ISO-68 AW20 for the fluid. So far it has worked great for me.
Now, talking to other engine builders they are telling me they are using ATF fluid (Mercron and Dexron) in the same application. The reason they give is the fluid is already thin so no need to wait for the fluid to come up to temp to get accurate readings. They also claim it is better on the pump for wear. When I ask them why they use it, the standard answer is always "because that's what xxxxx is using". No one knows the real reason behind using it, only because that's what they have heard of others are using.
What is your opinion on using ATF in hydraulic applications.
The service is generally 1500-2500 psi, 90-120 degrees F, no oil cooler or heater.
Thanks,
Jamie Webb
