Topic: Progressive Shock install question

[bunghole]

I'm just installing some Progressive rear shocks on my '77 750K.  The shocks come with some spacers with instructions installing in "all four shock eyes".



However, the spacers dont fit on the bike, so is it OK to just use a washer and acorn nut as follows?:



How much lateral movement is allowed on the upper and lower shock mounts?

Thanks!

The shocks should have minimal or no lateral movement.

I would make sure the new shock is  "vertical".   in the left/right plane.

Isn't there enough space on the bike side of the shock for that spacer?  Kinda looks like it from the pic, but I'm not sure.

it looks like the sleeve/spacer is already installed in the upper shock eye in that pic. Mine came with those installed, and another set of sleeves (10mm ID?) for mounting on bikes with smaller diameter mounting bolts (like my old RD400). You dont need them on your CB if the eye and bolt have no/very little play. You do need some spacers on the outside of that shock so your acorn nut snugs down and you are left with about 1mm or so of of gap, preferably on the inside of the shock. If your kit didn't come with any or enough (you will prob need 1 inside the clevis on the bottom too) hit your local friendly hardware store, I used both grade 8 steel ones on the nut side and brass ones against the eyelet and clevis.

As has been mentioned, it will take a bit of work to get them to sit up perpendicular, but it is worth it, these shocks rock. Is your set old or second hand? My instructions were different and more clear, I can scan them if you like.

I will search for my thread on the install of my set from November ,and post a link.

Thanks guys!

You answered my questions.

Here's another...

The bolts that were on the bottom of the old shocks were fully threaded and threaded into the inside section of the bottom shock.  There was no additional hardware (ie washers or nuts).  Is that how they were stock?  Is it OK to use a fully threaded bolt, or is that going to tear up the shock?  Should I just use some loctite, or do I need a lockwasher?

Thanks again!

I didn't use loctite or a lockwasher on top or bottom. You should hit up a local hardware for some good bolts that are not fully threaded, I used grade 10 ones. Bring your old bolt to ensure right thread pitch and maybe get the stock length and a pair 5mm or so longer, I needed a bit more then stock length on the drive side once I used a few washers to get the shocks to sit straight up and down.
