Full Floater

Thanks for the insight!!! Is the oring kit a "kit" that I need to order or are they standard orings?

Reverse is becoming more troublesome to engage lately on my RS600. I have a 12 speed with the air selector reverse. Im having to try far too hard to get it to engage reverse. I'll inch it around in forward gears a bunch, in and out of the clutch and other range selections until finally it will grab reverse. I don't hear any air leaks. So where can I start looking for an issue, I have just ordered a new air line filter, Mack# 2MD3131. After that, im lost. I have attached a picture of the air solenoids/valves on top of the tranny. Which one activates reverse? Does anyone have any tips in engaging reverse? Yesterday I had to free wheel down a small hill because I couldn't get it into reverse. Other times it goes in as easily as it used to. But those times are becoming fewer and further between.

Hi. Just got back from a 4, 12hr day gig delivering water for forest fires. Truck did pretty good overall. I used my power divider quite a bit and it seemed to operate just fine until yesterday. I had it engaged for about 3 miles of hill, loose gravel so there was some slippage from time to time, but it worked well, no noises no nothing. Now its not engaging anymore. I can't hear it click in and the light isn't coming on in the dash anymore. The bulb could be burnt out but I don't think that's it. I have attached a picture of what im assuming is the power divider unit. Am I correct in thinking this is the divider unit? What can I look for when trying to find my issue? I have never worked on a power divider before...

Mine even does it when im steady on the throttle. Kind of annoying

And would that usually be a worn bushing issue?

Well that's sure great to hear. I thought for sure I had a $5k + shop bill in my near future to have some bushings done.

Hey. I have a 79 RS600l. It is a low mileage truck and has never had any suspension/bushing work done. I don't know camelbacks well at all. But what im noticing is that after turning a corner and parking; the axles dog track a bit. The front drive axle seems to go one way or another more so then the back but its hard to tell. Then it seems to straighten out going down the road. Is this at all ''normal''? Do I have something that is severely worn out?

I have a 3" Bowie PTO water pump on my 79 R600. When i bought the truck, the PTO drive shaft was broken due to driver error. Anyways, im getting a new one made; but i have never used the PTO in this truck or any 12 speed for that matter. What are some basic guidelines? ? For example...how do I engage and disengage, what kind of rpms, what gear do I use? And does anyone know anything about Bowie water pumps?

Is that spade a part of the "puffer"?

What is the proper terminology for this steering ram? Its on the passenger side of my RS600l. There is play in both ends, the end that resembles a tie rod end has no grease fitting and is wore right out. It threads onto the ram and hopefully its available separately. There is also play in the other end where the cylinder attaches to the frame.

So here is a picture of my pump. (Dirty, I know) On the back of the pump, there is what looks to be a make spade electrical connector with a nut under it, with nothing attached to the connector. And to the left of the throttle arm, there is a set screw with a locking nut, is that the fuel delivery adjustment screw? And that is a picture with my throttle to the floor in the cab....is that about the angle they are when wide open usually? I can push it a bit further, but not much. This engine is an EM6 300.

Does anyone have a picture of the puffer? just so I know what im looking at?

Yeah that's the one, the spin on one. I'll see what I can find thanks. Does lube need to be applied to the seal when installing? Is there any way or need to lube the air valves when the filter is off?

And what is the filter for that is mounted off the top rear of the transmission with all the little air lines running to it? Does anyone have a part number for it and filter change interval opinions?

Totally!! Yeah old wiring is the one thing that scares me about our old trucks. Where is the buzzer on an R model? And is there a trigger on the air gauge or is there a seperate device to trigger the buzzer and light during a low air situation?

Ok maybe ill replace it.

I have a 79 rs600. The audible and visual low air warning devices both work on the truck but not all the time. If the air is low and i turn on the ignition, they will both come on. But sometimes, if the ignition is on and i fan the air down; the low air warnings won't come on. If i turn the ignition on and off a bunch it will usually start working again. Do you think this is an ignition switch issue? What actually triggers the warning? It almost seems like there is a loose or dirty connection somewhere. I would like to try to find/clean everything related to the warning system but don't know where to start looking. Again, thanks for all your advice in the past little while fellas

Ahhhh one of those tasks, I see! Ok maybe I will tackle that if I feel that I have had enough practice and its still not as smooth as I would like. I have the two pistons...at least I think that's what I see. Here is a picture of the truck performing its first paid job

On the top lid of the tranny?

Hmmm ok. I will try some more and see if I can get it. It just seems that if I preselect, it will grind during the second or two that it takes to achieve the desired rpm. Maybe this is normal? I just cringe every time I hear it.

Im still having issues downshifting from OD into direct, without changing the main gears. Am im supposed to clutch and at the same time, increase the rpm to match as I select direct, then release clutch? I now have the upshifting pretty darn smooth and im happy about that!!! Thanks

Ok, that makes sense. Thanks for your insight

Does the air system typically get enough lube from the compressor blow by? Is is good practice to add a small dose of some kind of lube once a year or so like ATF? This is for a 1978 R model that does not really have any air leaks but I just want to keep it that way and was curious about lube. And if so, where would I add it? Thanks

Also, here is a before and 3 afters, of my recently acquired RS600. Just gave er some new paint. cleaning it up and getting it licenced again. Its been an off highway truck for 8 years.

What kind of operating temps should I see with my 1979 E6 300? It runs around 160 without much load and climbs to about 200-210 when worked harder. Is that about normal? What is the "I should be concerned" temp?
