6.5 starter HUGE problem

To start, its a 94 GMC 2500 diesel on 37s. its doubles as my DD.

Anyone who knows the 6.2 and 6.5 diesels has probably heard of the bracket that holds the tail end of the starter so the starter doesn't bounce around and break starter bolts. well I couldn't find the bolt to hold it to the block, and I was waiting til it warmed up to replace it

Well this morning after my PT test (I'm in the Air force, and thankfully this didn't happen before it) my starter starts grinding like I broke a bolt. Take off the slave cylinder, take off the bolts, and a good chunk of my engine block comes off with it...

what do I do now? I can't drill and re-tap air, half of the original bolt hole is laying underneath my front tire. To complicate things, my other dodge diesel wheeler/dd is missing a transmission, so i need to get this done quick.

Only way Ive ever seen that repaired is to have the engine out and upside down on a stand , and braze the broken piece back on. Not what you wanted to hear I know , but Ive seen several break and thats the only way Ive seen them repaired.

As I saw the peice fall to the groud, I saw the mental image of me pulling the engine, so it sucks, but i definitely see it in my future. I'm just trying to not have to replace it.

If its a stick you could always have some guys in your company push you off until you can get the engine pulled out.

since it is a stick you can get a old style bellhousing that the starter mounts to instead of the block.

what tranny is it?

had this happen to my 6.2 while I was working in Colorado, one winter. Cept I just broke both bolts off in the block.... the little bracket that your talking about is around $21 from GM.. the 6.2/6.5 and some BB used the same bracket, the bolt that holds the bracket was around $3.00 from GM,, Metric threads. The 6.5 is capable of running a Powermaster )or comprable equivilant) Gear reduction starter, this is what I ended up going to. as I had a Turbo oil return line that I plumbed into the oil pan too close to my starter to allow the use of a regular 6.5 starter... the Gear reduction starter was smaller in appearance and spun my irritable 6.2 off with 1.5x faster starts...

if half of your bolt hole is still showing, and it has threads, I would track down the support bracket, install it, and get a new starter bolt and thread it in with alittle thread locker untill you can get the trans in the other truck long enough to get this engine, out.... you may can get lucky and find some crusty old fart that can do it in place... I certainly wouldnt go thrashing on it.

Other than the input bearing retainer size is the trans bolt pattern different?
I know the input shaft length is 1" different between Chevy and Dodge. Is the input length on the nv4500 longer than a 465?

This seems like a good modification to make for a permant fix since the starter bolts completely to the bell housing on the old style. It makes changing the clutch easier too.

the shaft length between the 4500 and the 465 is differant, and the spline count, and hte physical height/line up. the old cast iron bell housing with the 3 bolt starter that has been refered to on here, is a null point, tryed doing this some years ago with my 6.2 diesel with the 465 tyed to it.. this is not a good solution to the starter problem, as you now have to relocate and fab the clutch linkage/ hydro. and the gasser starter for 1955-1972 doesnt spin fast enough to reliably launch off the diesel @ 22:1 compression, especially if its cold. Now to counter any one thinking of putting the Dodge bell housing on the GM 4500, then up to the 6.5...... think about what your saying..... it physically wont fit.
