Cummins N14 A/C compressor bolts breaking

Any ideas on my clackity clack under the rear head?

Is losing a lobe common on these n-14s.

Or wristpins ?

 

Welding would ruin the seal as too much heat. There were about 3 threads left in the hole. I bought a tap and ran it to the bottom of the hole, probably has 6 or so threads now. Slapped the old piece on with some jb quick and threaded the bolt on. Added some extra support brackets to minimize future vibrations.

 

I thought about jb weld I didn’t want to be the one!!! Lol. Good deal there’s always a way!!

 

There's 2 1/2" bolts that hold the compressor bracket down. One was not damaged at all so I felt pretty good about it with additional braces added.

 

I just used a square plate that was solid, or a complete circle, around the the 5/8's side bolt in a case like that. Welded as you out lined.
Have had problems with bolts on top in cases similar to this. Using studs as described worked better for me.
Let us know how that works out please.

 

Doesn't appear that the bolts were threaded very deep into those 2 thread holes that busted out.


Proper length bolts and lots of locktite I feel would go a long ways on my truck.

Where did you buy that conversion bracket are there to pieces or just one, I have a Cummins N14 with the York style compressor and is driving me crazy y already buy a Sanden compressor but I haven’t being lucky finding an original bracket for the Sanden.

 

Part of the problem is a standard sanden won't fit with the tuflo 550 air compressor. However, I have seen another n14 with a sanden on it but it was a different air compressor with the piston farther back to allow for a sanden. Can't remember the name off hand

 

I converted my York style ttc to a Sanden, On my Detroit. I simply used 2 pc of 1.5”x1.5” steel tubing. Drilling holes to mount it to old bracket, and 4 holes for Sanden compressor. It worked good. Bolt pattern is closer on Sanden, and clutch pulls is smaller. The 1.5 tubing gives just enough room for bolts, and enough height, to use original length belt. I may have gone 2” shorter on the belt. Not sure, Dealer had confusing info on belt part # , they superseded it with a 2” longer belt. I ran it for a while. But also have problems with Detroit breaking bracket bolts. Finding proper fit for lines, clutch wiring, clutch pulley is the real challenge. The conversion bracket kit is useless for pad mount. Ear mount only. I’ve got a kit, never used it.
