Thanks for the reply. That’s probably the best floor insulation I have ever seen. Great job!

Sayyyy....... what brand of floor insulation is that?

I'll second that! When you install the new flex plate, remember to use blue Loktite on those special flex plate bolts and torque them to spec. You may want to clean out the threaded holes with acetone before installing the bolts so the Loktite will grab properly.

I have no desire or intention of engaging with you in a debate on this issue. To respond to your condescending remark, I can assure you that I completely understand these engines and how they operate. You are in business trying to sell your $300 kits. I get that. However having followed your...

Well at least now you know. I had to pull my ps pulley forward a full 1/8” to get it aligned with the water pump and crank pulleys.

Yeah swapping in a new Fluidampr was the first thing I done to my M1028 in 2010. My engine only had 12,338 miles when I got it. A little north of 15,000 now. My new P400 came from GEP with a new GM damper but I said, wth, might as well install a Fluidampr on there as well. So I have spent over...

There’s not much way to “eyeball” it. Trust me, 1/16” of an inch will make a difference. The alternator could possibly be close to aligned, but I would bet the ps pulley is off. Make sure all 4 ps bolts are in place and tight when you check for alignment. And remember that bottom ps bolt has...

The belt “strum” is a true indication of non-alignment. If you will align those pulleys all the problems will go away. Ask me how I know. Hope this helps.

Regarding your belts, I will suggest that you align the pulleys instead of diving into a custom idler fabrication. I’ve been changing belts on these things since the mid 1960’s and a few years ago I decided to figure out what was causing the belts to stretch and squeak. I discovered that the...

I bought those lights a few years ago from a lady on EBay who stated that they were for a Pinzgauer.

What a bummer. I am assuming you will tear down that engine to find the problem. What block do you intend to pursue? Rebuilt or new?

The tach body will pass through a 3-3/8" hole. There will need to be a small notch at 6:00 for an indexing ridge on the tach to fit into. Hope this helps.

Yeah let me get back to my shop and I’ll measure it for you.

Thanks !!!

Thank you soooo much! Yes I have the 4-screw tach. Question - would you happen to have the male end of the cannon plug so I can fabricate the harness from the sender to the tach? Here's a couple photos of the female end at the sender -

Warhorse - Thanks for your reply. I apologize, the thread is so long and old that did not read all the way back and see that the OP intended to install the tach in a civilian truck. Regarding my tach, do I understand you correctly that the sender that I have will indeed provide the correct...

Because the military tach is a 3500 rpm gauge which is more responsive to a low-rpm diesel engine. I am preparing to install a new HMMWV 3500 rpm tach in my M1028 in a custom-built cluster and have the HMMWV sending unit which mounts on the oil pump drive, however I have not tested this...

Yes that is indeed very interesting. I appreciate you posting the link. I will keep this in mind when I go to dropping the P400 in place. If the girdle or pan will not clear the OEM crossmember I will try to compare the ORD part to that beast and see if either will provide clearance. I AM...

Here's an early photo of the P400 girdle showing the front of the pan. I took this photo as the engine came out of the crate from GEP. There's a possibility that the pan will clear the OEM crossmember, I'm just going to need to get the engine started into the space and see. I am anxious to...

Nice work. I’m interested to know how much additional clearance the ORD crossmember provides under the front of the engine. Please post photos of this when you get to installing the engine. My P400 has the extra girdle which spaces the oil pan downward. I’m fairly certain the front of the pan...
