      Pictures of the Week

      By Vladislav · Posted

      After reading that I wouldn't mind any sealing of the new tank. Just put it on and be happy. On the other hand (my usual thrifty approach) I see no principal troubles cleaning the old tank and use it. Algae is not corrosion so can be separated off the walls. I'm not almost sure on the principal of its build up but as long as we concluded the origin is penetration of humidity into the alcahol that means we deal with water of some kind. If so the derbits could be products of aluminium corrosion (what is doubtful) or organic reactions in the water. If so you should clean it with stuff which dissolve fat or other organical dirt. Something of what is used to clean clogged kitchen sunk. Sure after test application on another aluminium part.

      K-7 trailer hitch for Jo-jo

      By Geoff Weeks · Posted

      I am going to take the 5th wheel off one of my junk frames and make an adapter to drop on the back of the K's bed, already am working on the compressor mount, have plenty of air tanks and compressors laying around.  If I really wanted to do it right, I could get an air pack to replace the hydovac and then it would be legal to pull semi's with it.  I only own a storage trailer now so no big deal.  I was presently surprised at the cost. Calling around for "small bits" of steel the prices were high.  This has the added value that if stopped by a DOT cop, it has the factory weight rating sticker on it.

      K-7 trailer hitch for Jo-jo

      By Joey Mack · Posted

      That is pretty nice. Thank you for thinking of me..  My plan for the truck was to be a toy..  I was thinking about putting a 5th wheel on it for looks, and a short rack body behind the cab for groceries ( I do have 13' of frame behind the cab)   I didnt think about a hitch.  however, if i'm in a parade, I could pull a hay wagon full of kids and their parents.   Hmmm...

      K-7 trailer hitch for Jo-jo

      By Geoff Weeks · Posted

      Thought you might be interested in this, 16,000 lb hitch for the K-7. They make a 20,000 lb version but realistically I don't think I have anything over 5,000lbs I'll be using it on. I had 10,000 on the bed before, however.  If I am going much over that, I'd want a 5th wheel over the drive and not a rear pull.  The truck had a hitch (holes seen on the rear) but it was too high for everything I tow, and always ran into it when I was working around the back of the truck. There is a 1/2" plate steel there welded into the frame and braced diagonally from further up. Very stout. I left all that, and added in a axle U bolt to it from the receiver, which should add even more strength to the already over built 16,000 factory rating.    This set-up is all behind the rear of the truck when the ball mount is removed.  I got a N.O.S, Kelsey-Hayes electric brake controller rated for both 6 and 12 volts. In the lit for it (circa 1975) it stated that ALL electric brake magnets are "8 volt units" suitable for use on both 6 (7.2 volt) and 12 volt systems. I don't think much has changed in electric brake magnets over the years. The K-7 has all the brakes it need to stop over 20K but if the bed is unloaded, the trailer can push the rear around, that is where trailer brakes make all the difference.  Most states don't require below around 3500 lbs, but I have two single axles I spec'd with brakes anyway.  I looked into buying metal to make my own, but the whole ball of wax including the ball mount was around $160 and I couldn't come up with the steel for that price. Pictures are the final fitment prior to tack welding the cross tube, then remove the whole thing and weld in position. Bolts to the frame with 5/8 and 1/2" grade 8 frame bolts.

      Etazb673 rocker arm adjuster 73gc27d new 2562411

      By RS Disposal · Posted

      Thanks, It was worth a try.  Maybe I can locate a blown donor engine.  Really weird being the rocker arm itself is readily available.   Not sure if they can be rebuiilt/repaired. I believe I have one that is damaged when a valve spring keeper broke and the exhaust valve stuck a piston.  This one just wont stay in adjustment

      also "back in the day " the gas like many items today was very different. wouldn't consider the hose/  suck the gas from tank in today world.  if reason is for mechanical reasons it's understandable. tank needs to have a pump  etc, the algae stories many prove other wise .

      I know fuel tanks outside the frame rails must be able to pass a drop test, filled and dropped at different angles and can not leak (or leak more than a spec'd amount) to be approve for road use. I do not, however, know if gasoline and diesel have to meet the same requirements or if gasoline is stricter requirements.
