Popular Post 66dc75 Posted January 26, 2018 Popular Post Share Posted January 26, 2018 So after a few years of steadily declining capability, the starter in my Autocar just couldn't get it done any more. I had a little time yesterday afternoon and decided to pull it off and get a new one. It looked heavy pulling it out with a strap attache to the ground lug standing on the frame rail with just one foot so I didn't dent the fender was fun. That freakin' thing was heavy. After I picked my testicles up off the floor I went and got a nice new 39mt which I could put in with one hand. Modern technology and aluminum is awesome isn't it? 4 Quote Link to comment https://www.bigmacktrucks.com/topic/52330-my-god-why-is-that-so-heavy/ Share on other sites More sharing options...
j hancock Posted January 27, 2018 Share Posted January 27, 2018 Same system for replacing the 6-71 starter off the Brockway. Straps, bad language, more straps! Hey , wait a second. You own a boom truck! I think we should see the "Barbie Jeep" golf cart at Bolton next year. It can ride over in the 67. 2 Quote JimIt doesn't cost anything to pay attention.

I was thinking I should use the crane but I would probably rip the hood of the truck doing it.

I always use the Peter Principle. . . . Hey Peter take out that starter, but be careful it could be a bit heavy. Than stand by sipping coffee with bandages and a truss near by.

Freightrain Posted March 9, 2018 Share Posted March 9, 2018 Ya, I remember doing the starter on my B. Ugh, to get that thing wrestled up in there and a bolt? WTH? Now I have a nice, light, aluminum air starter! WIN! 2 Quote Larry 1959 B61 Liv'n Large......................

Rob Posted March 10, 2018 Share Posted March 10, 2018 The only real drawback to the 39MT starter is the aluminum housing. It is best to paint the mounting flange of the starter nose where it butts up against the flywheel housing on anything that is cast iron or steel. The dissimilar metal corrosion starts quickly if this is not protected. Not much of a problem on a hobby truck that spends a lot of time indoors, but a working truck subjected to the elements is quite a different story with road salt etc. entered into the mix. Hard to beat the 40MT starter however it's sliced. Both four, and eight brush variants hold up well for many years and were very common; albeit heavy. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Popular Post davehummell Posted March 10, 2018 Popular Post Share Posted March 10, 2018 Every time i had to change a starter i was always worried i would loose my grip and it would fall on me. I found as the years got on they were making them starters a lot heavy'r 3 Quote Link to comment https://www.bigmacktrucks.com/topic/52330-my-god-why-is-that-so-heavy/#findComment-393854 Share on other sites More sharing options...

The permanent magnets help set up the field to pull the armature around lessening the electrical draw so smaller components can be fitted. Seen some hold up well, some not so well. A good starting engine that is maintained well with let a 39MT live a good life. A hard starting engine will not, as will the severe duty of extreme cold temperatures. I don't have any 39MT so can't speak from direct experience but around here the 40MT is still more popular than the 39MT.

Permanent magnets became much more efficient in the recent years. That's also the reason modern loudspeakers utilize magnets of much lesser size than before.
