I haven't been in a Mack rocker cover for at least 20 plus years and can't remember how I set it all up but from what your saying and what you've found I would say your losing pressure to operate the brake . I would set / check the tappets and brake set up then you have started at the beginning then if all is ok run it on the road and operate the brake as you would use it if this proves no good possible then the solution is the lose of oil pressure in the brake it's self .

Mack's have a very proud presence with them , When I first saw the Iranian Macks in Yugoslavia coming up to Europe with the Trilex wheels and the big fabricated fuel tanks it was love at first sight . You will be a very proud man when she's finished .

Welcome

Tidy truck , what engine do you have there ? In the UK if I remember they had the Renault engine , I saw Magnum's in Italy with the E9 very tidy truck going back a few years now . Les .

This is not my Mack but this is a good picture of what she looked like

Hi , Chris1953 haha , I'm les n 1952 model , the model of Mack I ran was a F786STMack the same can be seen owned by Overdorp transport Holland , possible came from them , I recovered mine from Germany with the gearbox gone then converted with a second hand box to the three position air change five position stick if that makes sense , high / low / reverse in each five stick positions , could be a bit of a bastard if you stopped in third then went in to reverse on the switch and got court out . Now then North Queensland Australia hows it goin . Les .

This was 25 years ago now , there was pictures coming home in Kazakstan over the desert it was hard packed earth no road for miles , we were trying to find a shorter route from Sammara in Russia to Symkent in Kazakstan to save all the miles on terrible roads going round by Almarta to Tashkent this the original Silk Road .

Hi . What a forum ! After being away from the trucking life I found a forum on youtube which took me through to a forum of Old Guys that I worked with from the 1980 throught to end of the 1990's driving UK to the Middle East and Asia , On the forum I have written accounts of my life back in the day Astran Trucks and Middle East Driving on facebook . I restored a Mack F700 Aerodyne cab , Newway rear air suspension change the gearbox to a air change system from the twin stick , the engine had a tip turbine and turbo charge system ran the truck from the UK to Newmont Zarafshan gold mine in Uzbekistan in the 1990's , Very cool truck and great power should have keep't the old gal . Saw many Iranian Macks in the day they all had the big chequer plate fuel tanks very cool looking trucks . Going to enjoy reading on here . Regards Les .
