USD Fork Spring Compressor 91 1100

[Nick]

Just gone to rebuild the usd forks on an 1100M and was stumped to find that the spacers at the top of the spring didn't have any holes for a spring compressor to fit into?!  I've done other usd's from a TL1000S etc and have always had them to work with.

I couldn't compress the spring without marring up the top of the spacer/playing russian roulette with the ratchet straps, so ended up drilling holes myself carefully in the spacer, which worked and allowed me to compress it.

Is this a standard practice when rebuilding these?  Or do people just rattle out the damper rod bolt and disassemble whilst it's not under tension.

 

I've always done them with the damper rod left in if possible, as it can be aggro when it spins...

 

Thanks

I drilled two holes in the spacer tube and used the compressor I had, it seems some have holes and some dont??

Thanks, Fbob...  wondered if it was just me!

I must admit i was very confudsed when I saw a set with no holes..

The ones I recently rebuilt to add to my Blandit did not have holes and I had to be pretty careful not to gouge the fork end cap internals.  Next time I will drill some holes once out.

Anyone know the internal hex size for the damper rod tool on these usds?  Trying to work out the correct tool for them to hold it in place...  or make one myself.  Thanks...
