cschannuth 3,816 #1 Posted February 12, 2021 Hello all. I’ve done quite a bit of searching and I probably missed it but I’m wondering if the dipstick should be screwed in or not when checking the fluid level in the Sunstrand Hydro? Thanks Share this post Link to post Share on other sites

Thanks Manual doesn't provide much guidance. Kohler is about the only thing in the world where you do not screw in the dipstick to read . (Techy B&S etc. tell you to screw it in) I doubt the small variance would make any difference the reservoir is quite large... I screw mine in but whatever floats your boat Edited February 12, 2021 by pfrederi 1 Share this post Link to post Share on other sites

Yeah, I checked the manual and it didn’t say so I will probably go ahead and screw it in. Do you know if it matters whether the Hydro has been warmed up through use or is it OK to do it while cold.

I think as a 'good practice' it's always best to warm it up a bit first. My hydro is a bit sluggish when cold. I let it run for about 5 minutes before use in the cold.

rjg854 11,475 #6 Posted February 12, 2021 I wouldn't think it would matter if it was warm or cold, oil doesn't expand or contract so the level should be the level. 1 Share this post Link to post Share on other sites

Definitely needed a few minutes before it starts working normally. Maybe the oil is thickerer? Share this post Link to post Share on other sites
rjg854 11,475 #8 Posted February 13, 2021 If you're talking about operation, that's a different animal. My hydros seem to work right away, alltho I do let it warm up a bit before I put it to work. Checking oil level, I don't think it matters much if the transmission is warm or cold. 1 Share this post Link to post Share on other sites
