Thanks, that is great

Did the R models have 4 circuit protection valves before the primary and secondary reservoirs after the supply reservoir? I am working from the Bendix schematic, I believe there should be a third reservoir for auxiliary functions like the diff lock and wipers that would be supplied last from the 4 circuit protection valve.

Good day

I am looking for information on the air system on a RS797T. I would like to redo all the piping that is currently a mess. Does anyone have schematics, picture or information on the layout of valves and pipe the systems correctly?

Looking for a source of rubber mounts that support the front leaf springs into the shackle brackets (for lack of a better term) on an R700

I am looking for some original hood hinges and pictures of the front end of the chassis rail and radiator mounts.

Our '79 R797 had a 444 Cummins fitted so the bonnet was extended and additional pieces added to the chassis rails. I would like to take it back to the original hinges and front end arrangement

Thank you for the additional photo nicste!  Always nice to see an old dog at work.

Thank you for the link Swishy.  Looks as if Sachal does some very interesting fabrication.

That's quite the boat trailer your pulling in your avatar!  Might need to see a larger version of that photo...

Wow!

That Steering wheel looks like new, no cracks anywhere. Only my observation for Originality but it is on the wrong side of the truck  

 

She was brought into South Africa via New Zealand. Looking to find out how original the dash controls are or what's missing

Looking for some help on the original layout of our R797 dash and interior in general. Anyone for any pictures or ideas, thanks in advance

That image is a good start, thanks. Our trucks came through Australia but only has two lines to the trailer.

We have a trailer brake lever fitted and the truck brake on the steering column. I'm presuming those are doing the task of the system park and trailer park knobs of the never models. I don't  know what the trailer control valve in the image is.

Good Day

Does anyone have any diagrams or schematics of the R model air system. We have an R797 that we are trying to restore to original, over the year the air system has become a mess. On that note any wiring diagrams would also be greatly appreciated

Having trouble the TRTXL1070 transmission splitting consistently, i can get 1st to split sometimes but after that no other gears want to split. I am getting 60psi on the Lo/Direct reducing valve

The lock to stop the main stick shifting when in low reduction also seems to not be working

I have notice when the splitter is in the fwd position the exhaust port on the shifter is exhaushting air and when the splittler is moved to the second position from the front i have got no drive.

There is also nothing stopping the main shifter shifting through all the gears when the deep reduction is in low

Thanks for the info, makes dense to me.

The shift out of deep reduction, main stick to neutral, then shift out of low to high then select first again?

I am also hearing a hissing of air from the transmission when in direct, i am going to trace the lines but is there any other underlying issue that could cause this

Nic

Yea that helps out nicely, if i'm not mistaken deep reduction should only be used in first gear? How does the splitter on the box work, eg pulling away in 1st low you would switch to direct drive release throttle and when the throttle is applied again the shift happens and it changes in to 1st high, the next shift is to 2nd when ready to split can flip the splitter back ( back into the low positsion??) release throttle and apply it again to shift, and so on through the gears?

Hope you can gather what i am trying to say?

Nic

Hi

Could someone please go over the correct way to shift for neutral trough all the gears (double reduction box). I would like to see what every has to say because ive had guys tell me a lot of contradicting way to drive the rig.

thanks
