Ford 1210 Lift Fail

[RocketMan2024]

Hello all. I am new here but been reading all about some of the problems with this Ford and all have been helpful in solving some issues. Very informative. However, i have a problem with my Ford 1210 Lift. It wont lift up.
A little background here. I inherited this machine and it starts and runs fine. 3 CY diesel and it is good overall shape. The lift would actually lift to any height but just would not stay there very long, ie 0ne minute and it would be on the ground. I was able to determine the lift piston seal was bad by the posts on this forum. I tore it apart and the seal was just in tiny pieces trapped in the piston grove. So i had to pay an exorbitant amount of money $57 + shipping for a new seal SBA050309016. I just installed it and NOTHING. it wont raise or even move.
So question is , what did i do wrong or is there something i overlooked? Is there a checkball/valve somewhere i missed?
I actually installed it based on the instructions i found on this site. Nothing to it, just install with the lip towards the pressure chamber, ie head of the piston.
Maybe somebody out there has done this with the same results? Please let me know.

Seal is a double lipped nylon variety and should be installed in correct orientation. The lip should face the lift cylinder head where the oil pressure and flow comes. The lip expand some against the cylinder wall to hold the pressure, rater than leaking in to rear diffy housing.


You can non-destructively take the cylinder head off , retrieve the piston for inspection. The only bad thing it is almost impossible to remove the old seal and re-orient without damage to the seal. soaking it in warm water might help some.

Sorry to hear your 1210 trouble.

I wonder why did the seal go bad?
Ford 1310 operator manual calls trans/hydr. oil change every 300 hours

I changed the transmission oil yesterday on my 86 Ford 1310 and it took close to 6 gallons of Ford 134 spec or equivalent oil (12-speed synchromesh manual transmission).

All seals are still original and there has never been any leaks...

Thanks for the input. Yes, i installed that seal exactly as you show it in the pic above. It did fit tight and i agree removing it would be a expensive mistake. I just can not understand why it wont lift now. It was working before i tore it down, it just would not stay up. Now it wont even budge. While i had the head off i cranked the engine and it was pumping fluid out as it should. Maybe the pressure is too low? Going to find a pressure gauge and test it. BTW. I measured that new seal so if i need one in the future it can be bought on Ebay for less than $10. Here is the size: 48MM x60MM X7MM. Had i known the correct size before i would have bought it before paying that jacked up price.

Ford 1310 operator manual calls trans/hydr. oil change & suction filter cleaning every 300 hours

I changed the transmission oil yesterday on my 86 Ford 1310 and it took close to 7 gallons of Ford 134 spec or equivalent oil (12-speed synchromesh manual transmission).

Those seals are good for about 30 years and then they seem to just disintegrate, LOL. AM going to look at the pump today and maybe change the fluid out as well. Hoping the filter is just plugged up and not the pump broke. Maybe i can use an alternative fluid, gonna check it out.

Correction to my post #3 above :

The suction filter should be cleaned every 100 hours & oil change every 300 hours.

You can check the pressure and flow to the lift cylinder head. Look at the pic below. If you have an oil filled gauge good to 3000 psi then you can use to see if you have nay pressure developed. Alternatively, you can just open the plug with a bucket under and have someone starts the tractor. You want to catch the oil. that would be indication of flow to the cylinder head. There are other thing to look at but got to diagnose systematically.

Ok thanks, gonna do that as soon as the rain lets up here in Houston area. Been raining everyday for a week. LOL

I do not have one but guess i have to buy one. What should the pressure be? When i had the head off i turned the engine over with the starter and fluid was pouring out. Just turning over with the starter and not starting it so figured it was good to go. Wrong assumption apparently. Will get back on this when it stops raining. First we had Hurricane Beryl roll through and then it started raining again a week later and still raining. Can not catch a break. LOL

So, look at the pic below, if oil came out from the port on the left of lift cylinder assembly with an o-ring seal then you are good as that is indication of pump working along with lift spool valve (3-point). it is good to have the gauge but you do not need it now.

Now as far as pressure. The hyd pump is a positive displacement gear variety. The pressure it develops along the flow is based on engine RPM. At the pump rated flow (GPM) and about 2400 engine rpm it should develop around 2100-2300 psi. That pressure is dangerous so need to be careful attaching or detaching pressure gauge there.

You need to look the orientation of the seal you have installed. That's where i suspect the culprit is.
