Winter is coming!!

COPG (clutch over planetary gear) starters are available for any truck. Newer have neodymium magnets and no armature. They are more efficient.

For heavy trucks I'd recomend Bosch ore Delco-Remy, other, like Mitsubishi ore Denso got no so good parts avalability. The most popular is MT44.

Our drivers build very cheap gas APU from used small scooter engines. I saw small 125 cc suzuki engine (water cooled, 4 stroke, fuel injected, singel cylinder) mounted in small welded frame with separated electric systems. One alternator charges small 44 amp battery, other - belt driven - charges truck. Cooling system is integrated to truck. good setup

 

I was pretty excited about getting a new gear reduction motor that is supposed to work miracles and spit out money. Then I popped my hood and noticed the truck has had an MT39 since before I bought it.
