kscarbel2 Posted February 5, 2019 Share Posted February 5, 2019 Doesn't Matt Pfahl (Pfahl Mack Restorations) have them? Or you can call the fine folks at Watt's Mack. 126SB127C - Complete gasket set for EN and ENF 707A and 707B engines 553GB3266B - head gasket (individual) EN707 with 20 studs 3029-8213C - head gasket (individual) EN707 with 18 studs Quote Link to comment https://www.bigmacktrucks.com/topic/55499-b-model-mack-gas-engine-parts/#findComment-414941 Share on other sites More sharing options...
CaptainCrutch Posted February 6, 2019 Share Posted February 6, 2019 Olsons just sent us our gaskets, they’ve got a few left. I’d try them first.

underdog663 Posted February 18, 2019 Author Share Posted February 18, 2019 Also, does anyone know what the torque setting is for the head bolts and the pattern? Mine's the B95 Thermodyne gas engine.

j hancock Posted February 18, 2019 Share Posted February 18, 2019 The final head torque for a Mack EN 707 is 150 ft lbs. I can't seem to find torque value for the first or second pulls. I would probably go 50 ft lbs on the first round and 100 on the second in sequence. After a little run time, the head bolts should be rechecked. Quote JimIt doesn't cost anything to pay attention.

underdog663 Posted February 19, 2019 Author Share Posted February 19, 2019 (edited) thank you sir . while I'm at it same question on the intake and exhaust manifolds Edited February 19, 2019 by underdog663 Quote Link to comment https://www.bigmacktrucks.com/topic/55499-b-model-mack-gas-engine-parts/#findComment-416016 Share on other sites More sharing options...
j hancock Posted February 19, 2019 Share Posted February 19, 2019 There may be an official pattern. IDK? I try to work from the center out on manifolds. Refer to a torque chart depending on fastener size, type of material and threads per inch (TPI). I probably under torque due to not wanting to break a cast iron manifold that may be difficult to replace. As usual, check them again after a few heat cycles. 1 Quote JimIt doesn't cost anything to pay attention.
