Brandon, great tutorial! I have two 760 motors that are leaking. Can you rebuild them for me? Also, could you let me know how much it would cost? Thanks.
Thanks for a great video and for opening up the comments! I have a couple of questions as I wait for the gasket kit to arrive: 1 - How did you position the pinion when you put everything back together. When FAAC ships it they have it set for the gate to be in a partially open position. Is that what you did? 2 - How do you refill it with hydraulic fluid? Do you just fill the reservoir and cycle the unit to move fluid into the cylinders, or do you somehow fill the cylinders in addition to the reservoir? 3 - What was involved in setting the braking and pressure bypass levels after the rebuild? Did you try yo fine tune it, or was that not really necessary? Again, thanks for a delightful video. I really appreciate the detail, and I bet it was hard to do that while you were also shooting the video!
1. I after bleeding the system I put the pinion in the gate wide open position and install it with the gate wide open. 2. To bleed the system yes as FAAC states in their manual you are to fill the reservoir and cycle various times, letting air out of the bleeding bolts. This takes about 10 cycles until the pistons start to budge and then you should refill the reservoir. After they are moving as they should top off the fluid in the reservoir. 3. if you are just putting in new pistons seals you do not want to adjust anything from what it used to be in that department. The manual does not provide the best info on how to tune the motors but with small adjustments of 1/4 turns and cycling you will begin to be able to get both sides of the gate even. If you have a wall on one side of your gate prepare for the gate to possibly hit the wall beforehand. the motor in the video had to be rebuilt again due to putting in the cylinder walls. You may want to get those parts too. If I was asked to do this again I would buy the piston cylinders from FAAC for $200 and get the piston seals on eBay for $20. They are 60*70*7 hydraulic piston seals. I did not mention it in the video but they install in one direction. So keep note of that when you remove the old seals. 4. Thank you and good luck with yours! I can do them in about 2 hours now and have had one gate working for over a year and the other has over 4 months (but with new cylinders I think it should be good for years to come). 5. Thanks Rick for getting me to get this info out there. I’m sure with my help and yours a lot more of these things will be in use.
@@brstarks7 I wonder if yoou could initially fill the two cylinders by removing the bleed bolts and filling thru those holes? It would be nice if FAAC produced some kind of document on their method for returning the FAAC 760 to its initial state after conducting a repair.
@@brstarks7 Just for clarification, are you recommending to buy new replacements for the two metal cylinders rather than trying to clean and reuse the existing ones? Was that where you were experiencing fluid leakage and loss of pressure?
Yes for one of the 2 motors I rebuilt the leakage was coming from one of the metal cylinders. They are quite expensive and also hard to find but I feel like a machine shop should be able to make you new ones (if they are no longer available) as they seem to be identical to piston sleeves.
A new system with new motors in the SF Bay Area will cost around $6000. You might be able to find a new FAAC motor online for ~$1500 per motor. I can repair a motor for around $1000 total. The gasket kit costs about $140, the piston-rod-cylinders will cost about another $300. After shipping (to and from) you'll be at around ~$500 depending on your proximity to me. I'd repair it for a flat fee of $500 after that (500+500=1000). However, this will be up to you to properly install (bleed the hydraulic fluid in the motor and properly time). I will not give out a warranty for this reason

I did not do this but I’m sure it would not hurt the system to do. FAAC just states to fill and refill the reservoir during the bleeding process.

Hi Brandon,
I`m interested in repairing my FAAC 760. How can I contact you?
Thanks,
Alex
Great Vide, I would like to have you rebuild my 760 operator. What is the best way to contact you? Thanks very much!

Reply back with your email and I’ll delete your reply after emailing you
@@brstarks7 Did you get my email address? My wife thinks she may have accidentally deleted my reply. Thanks.
How much to do mine?
