nnnnope, simple concept; simple solution. I just can't figure it out

 

I've been rebuilding a 87 lt250 myself and I got the rear shock nitrogen filled at Costo for free. It's supposed to be charged to ~145 psi but they could only do it up to 120 psi and it seems fine to me.

From what I've read, it needs nitrogen since air in the shock causes friction which causes the shock to heat up and possibly damage something. Also it contains tiny water droplets which can cause problems as well so if you have a Costo around with an auto department, I'd say to give them call and ask.

As for the leaking seal, I'm not sure what tell you since I haven't had to take mine apart yet.

 

The leaking seal was the fact I was too stupid to put the blatter onto the cap before installing it.

I gave-up and charged it with air, not too worried about the riding conditions changing under shock heat. I decompress it and refill with air every time I go riding to release moisture etc. Works for now, got it all together went out ripping and hurt myself; I rolled it down a friggan hill side.

 

Damn that sucks, you and the quad alright?

I just got mine put back together and haven't had the chance to really see what it can do yet but I will in about a week.

What psi do you charge it with air to? I would just be worried that once the air in the shock heats up, it's going to expand and increase pressure. I'm not sure what the max pressure it can take is but I would hate for it to blow a seal or something worse.

 

Quad only has a broken fender bracket but me however I have burns and road rash up my leg along with a fractured metacarpal, fractured knuckle and sprained wrist. Could have gone much worse:



The pressure is not that great, just enough to change the stiffness nothing more. My shrader gauge does not go to 150 so I just eyeball it I only weigh 115lbs.

 

Dude, Don't put air in it. Get it done right (and safe).

How is that unsafe?! There is nothing wrong with air besides slight decrease in component life and uncertain riding stiffness once it heats up. I'm not jumping the thing it does not heat up that much I weigh almost nothing. It's $40-$50 to have it filled screw that

 

Holy s*&t! that looks pretty bad.

The component life isn't the problem, the pressure build up if it gets high enough can blow the reservoir.

Have you tried asking any tire shops around about nitrogen fills?

 

Trust me I checked everywhere only 1 place and its $40-$50 (they know they are the only one's) I tried the dealership too.

 

That's too bad, hopefully the air charge works out for you.

I just saw your restore project post on your quad, looks pretty good so far. I'll be restoring an 87 lt500 quadzilla this winter so I'll be sure to make a thread for that.
