I have just received my new bearings, wow you can really see and feel the difference. These SKF bearings are top notch quality. Well worth the money.
Awaiting the new grease "Loctite 21030 Super Lube Grease" to arrive.
I am not quite 100% happy, but hey this is the first time I do this.
It was quite simple to put it back together, the bearings can be tricky to install. There is a night/day difference with the old bearings.
The hardest and longest thing to do was to adjust the worms, it takes time and patience....
But, all the issues I had before are now gone, no sticky points, everything is nice and smooth.
I would recommend it if you do have an old HEQ5 pro mount.
I changed all bearings in my HEQ5 couple of years ago as well, the larger axis bearings probably didn't make any practical difference, but the small worm bearings were definitely a big improvement.
