I am about to install an L-9 holding valve on a 444 serial#9710071. After cutting and removing the remainder of the 90 degree fitting in the top port of the hydraulic drive motor I will need to install a straight 7/8" o-ring to 5/8" tube fitting to attach the steel tube to the h-draulic motor port. Is there a "name" for this type of fitting or adapter and where to purchase? Also has anybody found an easier way to cut the elbow other than a hacksaw?. Thank you for any information.

You can use a SawZall or a Dremel Tool or an angle-grinder with a cut-off wheel, are both optional methods but it's a good idea to force some grease into the fitting to capture the filings or grindings to keep them out of the drive motor. You just need enough to fill the fitting far enough so you are cutting through the grease. When you remove the balance of the fitting, the remaining grease should come with it along with the nasty, metal bits.

Any decent hydraulics shop should have the fitting you need. Just take the 180 degree steel line, along with the O-ring half of the fitting you are about to cut and explain that you want a straight fitting instead of the 90.

I was thinking of a cutoff wheel but was concerned with space. after I get the bottom elbow off I will try that first. thank you for the info

I just went the other way with this and pulled a holding valve off. To be able to install the 90 I pulled the left rear tire, fenders and seat pedestal and removed the fuel tank and the six bolts holding the transaxle to the frame. Just had to pry/lift the the frame a little to start the fitting. Thought I might have to pull the brake but didn't have to lift far enough for it to be a problem. Replaced the rock hard fuel line at the same time and it only took about an hour total.

in my opinion the seller should have included ALL the nec. parts for this swap.
this being said you need a SAE to JIC adapter.
go to your local carquest store, then Gates fittings/ adapters.
