I just got done stopping a leak at the forward end of the KSB valve.

Intercooled engine.

This is not the first injection-pump leak that I have fixed using O-rings from this set :

So far, none of my repairs have failed, control-valves, throttle rods, KSBs, etc., so they must be okay O-rings.

It has kept me from robbing O-rings from complete VE seal kits.

For the intercooled KSB that I just fixed, wrench size was 17-MM; O-ring was from position # 111, the stack that is located dead-center on the box lid, size P11, W = 2.4, I.D. = 10.8

I just screwed the fitting out, replaced the O-ring, and screwed it back in; whole job = maybe five minutes.

No tiny projectiles shot out into the gravel; no un-identified springs or gizmos came shooting out; maybe three table-spoons of fuel poured out the hole.


Before, it was a steady drip---drip---drip, the entire time the engine was running.

Now, it runs dry as a bone.



I put this thread here so that others could benefit from my experiences.

I hope it is beneficial to someone.

Thanks.

 

Cheap! I'll have to pick one these up next time I'm at HF.

 

Can't beat $10 for that kit. I have a viton kit I was given I havn't tapped into yet. Keep forgettin it's there. Good tip.

 

Get the American sized set also; I am constantly fishing around in one set or the other for whatever projects I may be working on.


While you are there, get yourself a few rolls of :


X-TREME TAPE

Self-Bonding Silicone Wrap --- about five-bucks the roll --- 10' per roll

Made in USA by VYPAR

It usually is found hanging on the shelf among the various tapes.

That stuff is AMAZING.

I tried for weeks to find a replacement bottom radiator-hose for my 1972-model Mitsubishi two-cylinder diesel tractor; so rare that I have one of only two known to exist in the USA.

No match, nor even pieces of two hoses grafted into one, could be found that could be made to work.

The original hose from 1972 had a knife-like incision about an inch long and many old war wounds and abrasions.

I followed the instructions on the X-TREME TAPE and wrapped the hose from end to end, lapping my wraps by half-a-tape width, three layers deep.

The silicone tape sort of melted itself together, self-vulcanizing to itself, such that I can't even see the wraps.

I really put it to the test last summer, bush-hogging and mowing many acres, and never lost a drop of coolant.

I now keep at least two rolls on hand at all times.

 

dude Excellent advice and just what I was looking for 🍻

 

I bought a set of Viton seals when I dropped my tank. I had an O ring that looked like it needed replacing. I forget which kit I bought. Didn't matter, my friend that was helping me had on that fit.

 

I used the search feature and this thread came up.
It was a good read before doing the repair. I had a few VE re-seal kits already, so I saved myself the trip to Harbor Freight.

Easy fix and seems to be clean and dry now.
