Popular Post h67st Posted April 23, 2018 Popular Post Share Posted April 23, 2018 I had my son help me move one of the trucks around...he got a good whiff of the diesel smoke from the tractor and he's almost hooked! Crazy thing about this old Ralph Smith truck...it has an air start, it's been parked behind my barn untouched for 12 years. I grabbed the air start lever and it had 10 or 15 psi of air in the tank!! 9 Quote Link to comment https://www.bigmacktrucks.com/topic/53190-corrupting-my-son/ Share on other sites More sharing options...
Rob Posted April 23, 2018 Share Posted April 23, 2018 Good to see another get their teeth into it. Always nice to have an interested helper. Lots can get done that way but I never did long term. Old air start solenoid valves and such were very good quality given what they had to endure. Not unusual for residual air pressure to remain for several months but years is very good.

Freightrain Posted April 23, 2018 Share Posted April 23, 2018 Mine did well for its first winter. It went 2-3 months before dropping off too low to crank. I hoped it would go all winter, but to no avail. Not sure if it was just the cold or valving? It's all new. Or maybe just one of the fittings isn't totally sealed?

Popular Post Hobert62 Posted April 23, 2018 Popular Post Share Posted April 23, 2018 The other year when I drug mine out of the shed to start working on it, i made my youngest son help too. He's been very interested with the whole project ever since. 5 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53190-corrupting-my-son/#findComment-397426 Share on other sites More sharing options...
Rob Posted April 23, 2018 Share Posted April 23, 2018 You might tell him it's easier on the hands with the chain wrapped around your waist to pull them. Don't let the wife know how the rust stain got into the clothes though..... 2 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Vladislav Posted April 23, 2018 Share Posted April 23, 2018 Increadable about the air in the tank. And one nice looking H67 you're going to convert into a pile of parts for your project 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/53190-corrupting-my-son/#findComment-397438 Share on other sites More sharing options...

yarnall Posted April 24, 2018 Share Posted April 24, 2018 We can't get my H613 to hold air in the starter tank unless be drain the brake tank. What are your plans for that H67? Mike.

Freightrain Posted April 24, 2018 Share Posted April 24, 2018 My supply tanks only hold for an afternoon at best. Likely the air wiper switch(again). I put a new o ring in it years ago and it really helped with holding air for a day. It was shorted lived. I just had to put a new parking valve in, and I think that has helped a bit now too. One time last summer I lost my start tank in a few days. I think there must have gotten some junk in the check valve going to the tank and it bled off quickly.
