Ttype6... just my 2 cents but be careful with those super cheap starter motors and alternators... as you probably know it's all off shore (China) disposable junk. I work for Caterpillar Diesel and we build all our own starter motors... for example some of the starter motors we build (by hand) and not on a assembly line are 24V, 36V and even 64V for locomotive applications. The average starter we build weighs about 100 lbs and this would be the most common 24V starter we make that fits most CAT Industrial V8's and some V12's and TWO starters on a V16 - which is used in a CAT 795F open pit mining truck.
Let me give you a real world example... the 24V 'old school' Delco-Remy (they were originally made in Anderson, Indiana) back in the day - direct drive starter motors that weigh about 100 lbs are used on all kinds of different public transit buses from Detroit Diesel, CAT, Cummins etc... most tech's hate replacing them because they are so heavy - BUT - they are heavy for a reason because they last. The cost of a starter like this would be around $800.00. You get a bean counter (non tech) that gets sold on a cheap off shore gear reduction starter because they are half the price and the techs love them as they only weigh about 35 lbs (vs 100lbs). BUT here's where it hurts - like the old Fram Oil Filter saying - 'Pay a Little now or a lot later"... driver turns the bus off and then goes to restart it on a 90 degree plus day and the starter just clicks (if that) because it's a cheap gear reduction starter... sometimes it will take out some teeth on the flywheel but usually just the alternator and batteries if they keep trying to crank it.
So the bus has to get towed back to the garage (about $1K to tow the bus) and then replace the starter with the 'old school' 100lb direct drive unit. So the $400.00 bucks the bean counter thought he was saving just cost $3 grand to replace - IF - the batteries and alternator didn't get toasted as well. I have seen entire transit authorities change back to 'old school' starters - 500 plus buses - because the gear reductions were cheap and disposable.
All the parts I use and source are Made in the U.S.A. - not offshore - it costs us three to four times to build the starter but they last and for a reason. I deal with the suppliers that build all the off shore China junk for Walmart, Pepboys, Autozone and it's all about the numbers - not - quality.
You get what you pay for.
