There are 2 spiral wound spring seals at at each joint they will be stuck and not move in the slot in the pipe section. They slip into the collar at each end. There is not a lot of tension on them and the collars do wear a grove in them from the seals. All three parts are going to be worn. I don't have a good fix other than having a machine shop turn up a new larger pipe section and slip it in each collar. If you can get the 2 manifold bolts loose the manifold collar pieces will spill around to get the pipe out as well. I just did this thing to mine. Manifold bolts are $22-25 each from Mack and the gasket is $14-15. The only place that would have manifold parts anymore is Dale Francis in Ohio. 440-254-4046. Super helpful Guy.

I have seen the short round tanks from time to time. Just so happens that there is one right here, maybe for sale, Take a look at the two rust free B cabs for sale recently. There is a shorty drivers side tank on that frame brackets and all. There could be a nice passenger tank there too. It just so happens the colors on that frame and cab match the B75 I got from Texas in 1996 and still have. My cab and tanks where in real nice shape.

Hi, New here but the math is EZ. What you have is 1900rpm's ~ .86 Trans overdrive = 2,209RPM's I think it is .86 for your Eaton 13 speed. 2,209 ~ (gear ratio) = Y Tire roll out in feet = Z Z for 22.5's = 11.00 Z for 24.5's = 11.52 Y x Z x 60 ~ 5280 = MPH 5280 feet in a mile 60 minute in an hour This is like you said for what you have now 499.84 x 11 x 60 ~ 5280 = 62.48MPH Reducing the equation Y x Z x .01136 = MPH This works for any ratio and the two tire sizes For 4.17 ratio and 22.5's 529.736 x 11 x .01136 = 66.19 MPH I have 3.76 rears in my RW on 22.5's and I like them @ 73.41 MPH Hope this helps as I see rear ratios have come up more than once.

They will interchange. I used a double disc pusher 864 clutch on my 866. All the 866 had a puller Clutch that I have seen.
