Correct Hydraulic fluid for 63 convertible top motor
I had a top motor issue due the resevoir being topped up by an upholstery guy with a fluid that was not compatible with the fluid already in the pump. The mixed fluid turned to foam after one going up once and could not lift the top back up. I removed the pump. How do I clean out the old fluid in the rubber hoses going to either side of the pomp? They seem to be mostly empty now but don't want to have nay more foaming issues. WHAT IS THE IDEAL HYDRAULIC FLUID TO USE IN THE MOTOR? The…See More
"Usually with the top up you can sit on the back seat, and unclip the convertible top liner behind the seat to access the motor, but since your top is stuck down, that doesn't seem like an option. I still can't image that they would somehow…"
"Chris, in your photo I see no access to the platform on which the pump rests. As I mentioned in another replsy, I saw an access area to the bottom of the platform from behind the seat on a 69 or 70 at a junk yard."
"Thanks for the photo, Chris. my motor must be different. Mine has no bolts going into the pump from above. All I see are the rubber grommets. The center of the grommet is open. No bolt. I was at a junk…"
"Unless they hooked yours up with different hardware, you should be able to get the motor unbolted with a 7/16 wrench or socket. Mine was only bolted down on one side surprisingly enough. As for the fluid, it's going to make a mess regardless of…"
"I think you are right regarding mixing the fluid types. The first thing I want to do I see if I can remove the resistance to me manually getting the top in the up and locked position. I have removed the plug with the 2 hoses from…"
"Thanks for your reply and photo. You saved me a lot of time by not trying to remove the seatback. I removed the 1/2 inch T with the two tubes that is located on the back (trunk side) of the pump. . But I will try to…"
"As you can see here there's not really any access to the top motor with the back seat removed. Your best bet would probably be to use some large objects like blocks of wood or whatever you have available to put on both sides of the top motor to…"
63 convertible Power Top Motor issue
Boys and Girls, Hope you can help. I was looking on the Website for information or manual on operation and repair of the power top motor. Mine was working fine until last week. I pushed the switch to put the top down. All went well and it dropped into the well. The motor sounded as it has always sound. I had a new boot made my local upholstery guy and he also topped up the fluid which had been a little low. It worked fine.. When I tried to put the top back up the motor did not sound…See More

1963 RHS A/C kick panel - photos needed
Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes
Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Loud air moving sound within carb with cleaner removed
Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like
While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
