Glad that so many found problems with this support and fixed before a failure occurred. We removed and did not have any cracks on aluminum plate but gasket has 2 splits which we think was cause by the bouncing on the aux. drive unit doing down the highway. An all day repair and a $14 gasket. Had lunch with Clyde and Sarah and enjoyed their company. They run a nice shop. I will not hestiate to drive 500 miles to their shop again the next time I need service. Still have some oil coming off the engine but I am hoping that it is residual oil left from loosing 1/2 gallon over 500 miles. Checked oil on the return and does not appear that I lost any. I am going to get the engine cleaned up and post a picture of the area hopefully sometime this week. I believe the support is common on all cummins engines.

Default 4 Bolts

I crawled under the back of my BMC and there are bolts everywhere of course. I am not sure which bolts I should be looking at. Some go into the engine block but I can't see another two connected with any of those. Where are they in relation to the oil pan for example laying on your back looking up at the engine transmission combination?

If someone could post or email (address below) me a picture or two to make clear where they are, It would be very helpful. Sorry for my ignorance, but about all I can identify under there are the engine, transmission, and air dryer which is on the passenger side of the engine.

Thanks in advance.

Best,

Default Bolts

OK, I found the bracket and the bolts on mine are super tight. There are actually 6 bolts. Two long ones go into the engine block and there are four on the other end of the bracket. I was talking with Jim Brookshire and found that the M 380's apparently have two of these brackets while the BMC's only have one. I have pictures of mine so if anyone wants to see what the BMC bracket looks like, send me an email (address below)

Lee,

How about post the picture right here in this thread, or you can send it to me or give me a copy at Myrtle Beach and I'll add it for you.

I'll need to get back in there and double check the M380 to make sure I didn't miss anything...I did find two loose bolts on initial inspection

I also took a quick look at baby birds 5.9 and all looked good but will look closer at that as well.

After reviewing this thread I crawled under my coach to check the hydraulic pump bracket bolts and found all to be tight. However, what I did find was the motor mount bracket on the passenger side had only 1 bolt in place and tight. The two upper bolts were completely missing and the lower left bolt was about to fall out. All four bolts on the driver side bracket were present and tight.

The passenger side bracket is a little difficult to access due to the wiring underneath it. In the attached picture you can see the loose bolt (red arrow). The red circles mark the location of the upper bolts, and the red x marks the location of the lower right bolt that was still tight.

I would use Lock Tight on those bolts.
