Cummins conversion

[QUOTE=Al's_F600;16437849]Rustyrelic

I have 2 questions for you.

Do you know the production years for rear end you used? I see a few Dana 80’s 1994,1995,1996,1997 available, I believe they are all from MT45's with 3.31 ratios. I have not found a 1999 like you, can I use a different years?

I don't know the production years, but if you measure the width of your stock rear end you will be able see if the dana 80 your looking at will work.
Make sure to that the dana 80 is a 6 lug and not a 8 or 10 lug.

Where is the check values located in the brake system so I can remove it/them?

On the stock brake system the check valve is in the master cylinder and can be removed and replaced with inline ck valves.... 2lb for disc and 10lb for drum.

I am very close to getting the rear end.
Where in the master cylinder is the check valve?

I have a 1956 parts book that breaks down every piece ofthe whole truck.

I see the brake switch going into the bolt with the hole thru it. Then to a nut that separates the fluid and goes into the booster.
All this screws into the solid reservoir.

Is it just not listed? There is only one opening that the fluid comes out of from the reservoir.

Where inside is it located?

Thank you
Al

Ck valve

If you have the factory service manual, on page 282 fig. 10 shows an expoded view of the master cylinder and the check valve that you need to remove is labeled "valve" and it will be the last thing to come out of the master cylinder.

Just remove the valve and reassemble the master cylinder.

Hope this helps.

You are a genius.

I was looking at the chassis parts catalog which just had numbers.

I did not know that the stuff to the right of the housing made it all the way over to the left where the fluid comes out.

Thank you again.

up with the 337 low mile flathead with a 5sp Clark overdrive !

So I have subscribed to this thread as I am looking at getting a 56 Dump and really see a need to improve the braking system. I am curious about the front spindles are they mentioned someplace else on the forum? I have been reading a lot here and figure I can find the rear end set up as there is enough info to narrow it down.

Master cylinder check valve is basic part number 2178 .. shown in pic on other side of master cylinder.

TH is the parts catalog symbol for an F600.

I have to ask will the cummins with an automatic fit? I found a donor truck but equipped with an automatic. I probably have to add something to it or swap out altogether as I need a PTO for the dump bed I have in the plan
