emealer1 Posted February 14, 2014 Share Posted February 14, 2014 Hey all. Going to make my way towards starting Big Bertha. I have no key and the cutoff switch has three unlabeled terminals so I'm unsure how to replace it. What do I need to allow it to start and to cut it off should it start. I'll be attempting a pull start. Quote Link to comment Share on other sites More sharing options...
Superdog Posted February 14, 2014 Share Posted February 14, 2014 if you are pulling it only thing you will need is the fuel shut off cable,in for run,out for stop. Quote Link to comment Share on other sites More sharing options...
emealer1 Posted February 14, 2014 Author Share Posted February 14, 2014 Pardon my ignorance but I'll be needing a lot of help as this project takes off. Is this on the truck or something I need to set up. My experience is limited to gas burners in vehicles much less substantial than this.

Superdog Posted February 14, 2014 Share Posted February 14, 2014 should be one on the truck,if it still has the original,it will be a round flat chrome knob with stop engine printed on it. Quote Link to comment Share on other sites More sharing options...
jaysm35a2 Posted February 14, 2014 Share Posted February 14, 2014 Have you driven a large semi before and know how air brakes and the truck and all work? Im just looking out for you, id hate to see you hurt or less the truck/hobby. We would be happy to ansewer all questions before you pull start and drive her around.

emealer1 Posted February 14, 2014 Author Share Posted February 14, 2014 I drive a tow truck for a living so I'm familiar with air brakes and all. I've done enough research to understand the concept of how to shift the duplex but I don't imagine that will help much in reality. My biggest concern is getting a temporary fuel tank plumbed properly and being able to shut it down. I was able to find a post showing how the cutoff works so now I just have to find the time to tear the fenders down and make sure that its working before we try to pull it off. I think the brakes may be backed off from when it was towed across town years ago so if by some miracle she runs, we won't be driving. We're gonna pull her off with a wrecker so stopping won't be an issue...yet. Thanks for all the help. I know I'm gonna need a lot more.

emealer1 Posted February 14, 2014 Author Share Posted February 14, 2014 I was able to go out to the truck today and found the cutoff cable. Unbelievably its not stuck. I see one fuel filter. Is there a second one hiding? Quote Link to comment Share on other sites More sharing options...
Mike Posted February 15, 2014 Share Posted February 15, 2014 I was able to go out to the truck today and found the cutoff cable. Unbelievably its not stuck. I see one fuel filter. Is there a second one hiding?If it is a Mack Diesel engine then sometimes they will have a primary filter on the driver side either up on the intake manifold or mounted near the bottom. Might follow the fuel line from the driver side tank toward the front of the engine. The secondary filter is normally mounted on the passenger side, front of engine mounted onto the water pump.mike Quote Link to comment Share on other sites More sharing options...
