I took all the brackets off and tried again, but couldn't get the engine back to the motor mounts. Tranny's got to move back. Should have kept the transmission jack I borrowed when I JUST fix the hydraulic lift pump. And now someone else has borrowed it.
The waiting games regins.
Should have bought that one I saw on craigslist a couple years back.
Well I need to get on the internet and be lied to again anyway.
Got another mission trip coming up, so delay is welcome... right now. Four weeks and I want this on the road!

[QUOTE=Keyair;1705236]Mel,
For your reference, here is some pictures I got from Dave(WXBouy), of his Original 6BT installed in his 345. Hope this is OK to post Dave...

Mel,

Since I have the only one (that I know of) with an original cumin's 5.9 6BTA up front, I am more than happy to take what ever pictures or measurements you may want. The biggest issue I had was replacing the motor mounts since they were unknown to anyone that deals with the P-30/32 chassis. In the end we just ended up pressing new bushings in the old mounts.

Let me know what you need!

Thanks. As I work on getting the motor in, I know that the original air inlet is toast. It's got to turn forward because I'm planning to mount the intercooler on the top of the radiator frame. I saw a Case fork lift w/commins (4 cylinder) and ordered that inlet, but it's a 2 1/2" so I'm back to squire one on that.
You know want the p/n is on the engine air inlet of yours?
Waiting for transmission jack before continuing.

This baby has the vacuum pump behind he P/S pump. Wish it have the air pump that goes between the P/S pump and the vacuum pump, could get rid of the air pump in the back of the bedroom for the air ride.

That's what I was thinking. The common configuration is the air compressor with the hydraulic pump piggybacked on it. Loose the engine driven vacuum pump. It's sized for a brake booster.

Cool Dave!
I think there is no better reference that your MH.
What Mel is doing is exactly what I hope to do... 6bt with a 4l80e. I think any info you have on your install would be helpful.

Got the transmission jack, dropped the drive shaft, moved the tranny back and got the block setting on the motor mounts, but can't get the bolt in. Looks like I will need to unbolt the bottom from the frame, get the mount bolts in then rebolt to the frame. It would be easier to do 15 years ago
No room to the A/C pump.

Got to get a different mount for the A/C.
Figure out some way to work the engine stop lever, no room for original.
The front cross member, the one laying in the frame under he motor, is scrap now.
Just been sitting here staring at it for the last couple days as I hunt for information on the 'puter

Remember I had to take down the hdy jacks pump? And I thought it'd be a good idea to find a different new location? Well I put the dang thing back up above the transmission. Guess what??? Got to find the different location now. It's in the way to get the transmission bolted up.

Had to cut some steel out too. This keeps up and I'll have less weight then with the 454.

Mel, don't know if you already have a gear venders overdrive installed, but now would be a good time to do this. While you are in there. Especially if you are going to shorten the front drive shaft anyway.

The ability to split gear for hills, both climbing and descending is excellent.
As well as dropping RPMs while cruising . A great addition for drivability.

Wish you well on the engine install. Thanks for posting the details. Most helpful for for gasser owners thinking of going diesel.

Cheers Richard

454 to Cummins

One little change leads to two new little changes, which lead to four more little changes,,, and so on, and so on.........




Brevi tempore!

Mel,


Just saw this (and realized I didn't subscribe to it before). Will get part numbers and pics when it stops raining today. Will also get you the list of part numbers for the filters and belts.

Brad,


yes it did. I haven't found any other front original cummins. So that adds to a whole new level of research since it is so unique and me with out any mechanical ability!

However, I am extremely happy with the set up.

Been (too) slowly slugging away.
Got the tanny bolted up and the rear cross member back under the tail shaft housing. About 1 1/2" farther back, so, got the e-brake and yoke back on then measure to the carrier bearing and get the drive shift shorten.
Built this frame to get the head back on top of the block. because I left the dang thing!!!

Want's going to be really fun is pulling torque on those head bolts on my knees. Usually takes me a couple day to get the torque down.
I can see the original air inlet is of no use. It goes over the injector tubes and no room for that.
