A little update on disassembly of the 74/75 shocks. I went to Ace yesterday and bought a couple of items to compress the spring. Basically a turnbuckle and some J-hooks and a long enough threaded bolt to go thru the lower eye and a couple of nuts and washer to space them out so the turnbuckle did hit the spring when you turn it. Make sure you relieve as much tension on the spring, use your shock spanner wrench to do this. Once you sent it up and compress the spring by turning the turnbuckle the thin chrome cover with drop down and you can see the bottom of the top mount, the jam nut and rubber doughnut that's on the piston shaft. The jam nut is 26mm. It would be nice to have 26 mm open end wrench, but I didn't, so I used a 1 1/16 in open end wrench. I might try to buy a 26 mm wrench off of Amazon. You could thin it out a bit too to make things a little easier. Grind the flutes of the open end side down an 1/8 inch or so. You can use a screw driver to push the rubber doughnut down a little bit so you can get the wrench on there if you don't have a thin enough wrench to get in there, that's what I did. Put the top mount eye in the vise, clamp lightly and put a little pressure on the jam-nut to loosen it and the top mount will spin right off, remove the jam-nut, de-compress the spring and it all comes apart. Then you can check the condition of the shock itself. Don't expect much from a 40 plus year old shock. But now you can clean, re-chrome, polish it and put is all back together. I haven't gotten to the put it all back together stage yet. On a side note....................I was thinking, maybe you could by one of those aftermarket shocks like Diablo sells, the correct length for a 74/75 H2 and take it apart and just use the shock with all the other OEM parts from the stock shock? I don't know at this time, but might buy one and see if I can get it apart. If anyone has any info please pass it along. Thanks, Ed |

I looked at doing all this. The only part you would reuse might be the spring, and I don't know about everyone else here, but for me it was way too stiff, so that might leave the upper spring cover as the only part left that you have stock. I was going to drill the stock shock and weld a small bung to be able to drain and refill the stock shock oil, but it's damping is that far away from good that just an oil change wouldn't make it good. |

Here is a couple of pictures of my homemade spring compressor, bought the parts at Ace. Works well............but of course use at your own risk. edit............FYI The shock in the picture hasn't had the spring tension adjusted to its lowest setting. The turnbuckles are out of adjustment, it is just shown for parts I used to make this. I haven't tried compressing the springs for re-assembly yet. |
