Hi, welcome to my site.  Please browse down for explanatory images on the Bullworker X5 overhaul (1980 model).

I have been maintaining my X5 for the last 24 years (honest!) every 3 years or so, in the following way.

Use normal safety precautions, such as protective eyewear.

Step 1: the chrome-plated tube is disengaged by holding one end of the Bullworker between the knees whilst kneeling down, then pulling down the chrome-plated tube with your right hand (if you are right-handed) whilst holding the top handle with your left, so as to expose as shown below; then, taking care not to twist the spring too much, pulling out the spring from the black plastic guide:

Step 2: the black plastic spring guide is taken out:

Step 3: the guide shown out of its place:

Step 4: both guides out:

Step 5: the springs are to be taken out of the chrome-plated tube:

Step 6: one spring out ...

Step 7: ... and the other spring out as well:

Step 8: the blue plastic spring guides are to be taken out of the chrome-plated tube:

Step 9: both blue plastic spring guides out:

Step 10: the handle cap is to be disengaged from the handle on the side where the traction ropes are not stitched:

Step 11: note the white plastic pulleys over which the traction ropes run:

Step 12: the pulley pins are to be pushed out with e.g. a watchmaker's screwdriver:

Step 13: one pulley pin shown out:

Step 14: note the stitched ends of the traction ropes at the other handle end, so as to be able to assemble back as they were, before proceeding to dismantle the handle from the handle cap and the pulleys and pins:

Step 15: prepare some water with a handful of detergent powder:

Step 16: wash the traction ropes in the water/detergent solution (it is good to give them a good soak, for example, a couple of hours, use only cold water), and hang them up to dry thoroughly:

Step 17: apply general-purpose grease to the black plastic spring guides ...

Step 18: ... in the same way, apply grease on the springs:

Step 19: apply light machine oil to the pulley pins:

Whilst the Bullworker is dismantled, it is a good idea to check the various parts for any excessive wear, rust, etc.

Re-assembly is in the reverse order of disassembly, of course.
