Shock oil

[Robert Kampas]

I'm working on my shocks. Don't think anything had been done to them in over twenty years by the previous owner of my project 47 TC. But they do not leak. Rather than have them rebuilt I decided to leave well enough alone and just flush and replace the oil. I used 20 weight motocycle fork oil. I emptied the old oil, filled once with new, worked the pivot arm several times, drained the new oil and refilled. I did this for all four shocks. Now three of the shocks seem to have the same resistance when I work the pivot arm but the fourth one has much more resistance. The one that has more resistance seems to have about the same as all four used to have before I changed the oil. Are you following all this? Which is right? The three shocks that now have less resistance than before I changed the oil, or the one with the greater resistance to movement of the pivot arm? How do I end up with all four the same? Or does it matter? Thanks in advance... Cheers, Bob Kampas TC2544

Bob, Difficult to say. It depends on the damping effect of the 3 versus the 1. If 3 are the same, then one might assume they are correct, and the other is a problem. It could be that the filter(s) on the piston(s) of this one damper are blocked. I wouldn't necessarily decide to leave well alone, and there is no rocket science to these. Have a look at the articles on the special files area for Luvax damper maintenance. Regards, DAI TC 6132 --- Robert Kampas kampas@seanet.com> wrote:

the 3 versus the 1. If 3 are the same, then one might assume they are correct, and the other is a problem. Assume can be broken down - making an ASS out of U and ME The council I WILL give is that the shocks should be fitted to the axles in pairs of the same resistance. Some air could be the problem - try another refill they should be quite stivv but this is difficult to quantify! Certainly a hard pull by hand. Clive

Hello Group - I think this was covered last Fall but for the life of me I can't pull it up. What is the correct damper oil for the piston Luvax TC shocks or something off-the-shelf that is correct. I assume it should be non-foaming but don't know about the weight. Please feel free to contact me direct rather than bomb the group. TTFN Sara [Non-text portions of this message have been removed]

hi Sara - you need motorcycle fork oil which is non-foaming. comes in several weights, but the 20 seems about right. cheers Roger

Hi Roger,

As it happens I still have some Girling Official Piston Type Hydraulic Damper Thin Fluid! If anyone is interested and has the ability to analyze the fluid I can provide a sample.
