Mark siebenaler 93 #2 Posted February 14, 2023 Could someone please verify this is the correct length obviously someone else put this in at some point. I usually make sure the oil is up to the o. In oil? 1 Share this post Link to post Share on other sites

ebinmaine 68,233 #5 Posted February 14, 2023 So a mid-70s Sundstrand transmission. I can get a pic with length in an hour or two if somebody doesn't do it sooner. You want to make sure this type of transmission is NOT overfilled per @daveoman1966 but I don't remember the technical reason. Share this post Link to post Share on other sites

Ed Kennell 38,609 #9 Posted February 15, 2023 Eric, is it possible Mark's Sundstrand has a riser pipe requiring the longer dip stick? I don't have any Sundstrands left...only Eatons in my barn. There are three different Sundstrand models. I don't remember if they had different length dips. Share this post Link to post Share on other sites

Thanks when I get a minute I will check the length on my riser . And compare... 2 Share this post Link to post Share on other sites
Ed Kennell 38,609 #11 Posted February 15, 2023 I just noticed, the C-160 used both the Sundstrand 1140 and the 1137. I'm not sure if they have different length dips. Share this post Link to post Share on other sites

Mine has a riser... But... I can't prove it's original or correct. It seems to be about the right set-up. Share this post Link to post Share on other sites

One is a slotted screwdriver slot in front of the left fender. One is a petcock like valve on the top left center of the transmission. One is a hex head bolt on the left rear back of the transmission. I'm not sure what number goes with the valve location. @daveoman1966 probably has this info.

Mark siebenaler 93 #15 Posted February 15, 2023 Without removing fenders or top covers I can not see a relief valve so I'm sure it's some sort of bolt or something hidden? 1 Share this post Link to post Share on other sites

Might be a bit tough to see but you shouldn't need to remove any sheet metal. Can you please post pics of your tractor so we can see what you're seeing?

The C-160 should have a 90-1140 unless it was replaced. The tow valve should be as shown in the picture. 90-1136 90-1137 90-1140 90-2046 90-2062 Share this post Link to post Share on other sites
