Cool Pulley Sizes

I have searched the forum and only found the exterior dimensions of the pulleys for my 31 ft. Hi-Lo. I want to replace all the composite pulleys with aluminum ones. Some of them are already busted and have fallen on the ground below the camper upon lifting. What I am looking for is the center diameter for the bolt that goes through the center of the pulleys. My camper is at my son's property (where no one actually lives). I want to gather all the parts for the lift system to rebuild it before I go out to where it is. All the cable and related hardware has already been ordered. Just need to order the pulleys. Thanks for any help!

Question pulleys ...me too

hey when you find out about the aluminum pulleys would you let me know where you got them from and what they cost. That sounds like a good thing to do. I also have a 31 footer (2004) and have done several mods to it already. Drop me a line and I'll tell you what I have done.

I do not remember the shaft size, but I replaced my pulleys and cable a couple of years ago. I used stainless steel cables. The pulley part numbers for those I used were 5RRX8 for the lower pulleys and 4JX69 for the upper saddle units. You can Google these numbers and get the specs. Hopt this helps.

Default Pulleys

Hi Savage, if I remember correctly I used 16 of the 5RRX8 and there were four of the 4JX69 saddle type. You should be able to get an exact count by crawling underneath the trailer, they are all exposed. One note the new pulleys don't squeeze the cable like the old ones, I could not find any with the narrow profile like the old ones, but I haven't had any problems with the new type. I don't remember if I mentioned, but I did use stainless steel cable for the replacement. The new pulleys had brass bushings, so they should long lasting.

Thumbs up pulleys

thanks for the info on the pulleys...so tell me where did you get the stainless steel cable and what lenghts were involved and where did you get them....what other hardware was needed to complete the rebuild. How did you jack it up in order to do the job. I would like to see some photos of this if they are available...thanks
