BCR’s also stand out because they typically lacked the R model battery boxes behind the front fenders and often retained the B fuel tanks. My ‘67 R611F (1003)and my ‘68 R608F (1006) both have the very small radiator with the side extension panels that look like closed shutters. My ‘89 R688ST tractor of course has the full radiator/ATAAC setup.

When I had the loose ball on the pitman arm, I also had a drag link that had the ball cap broken into multiple pieces. I had to order an incorrect PAI drag link to get the internal guts I needed.

The part I used was a 9QC3220P2. It has a bit more of an angle outward but connected right in and works like a champ. Completely interchangeable with 11R22.5 steer tires. Can’t say if it works on larger/wider tires. The part was $497.

I’m here. I just get caught up with life and trucks and forget to log in. Glad to see the book getting some attention.

Could any fine member on here point me towards the part numbers and a source for the pitman arm and drag link on a 1989 Mack R688ST? Drag link is 15” long center to center. Pitman arm is 9” center to center. I have a bad feeling I already know the answer.

So very very sad. Mike is a legend.

I’m sure there is but I don’t have it.

Here’s a partial scan of the first 20+ pages of the 342 pages. I can look up something if needed. 982381310_MackR600SeriesCollisionRepairBookRev1991.pdf

The RB, RD and DM all used variations of the same cab architecture and were produced until ‘04-‘05. The DM stopped in ‘04, the RD stopped shortly after in late ‘04 and the RB stopped in ‘05. Late production numbers were very low. Of course, things between models were different with cab cowls, door skins (DM) and other sheet metal on the DM to accommodate the offset. Dash panels, door guts and other things were common though. Most of the parts are no longer available from Mack in my experience. Dash boards and switches were updated across the RD, RB and DM in March 2001 for ‘02 and up models. This included stainless bezels on all gauges, new gauge faces, all new switch hardware and layouts and other things. I always use my former ‘02 RD 690 VIN last six was 033790 as a parts reference. I custom ordered it and it was built April ‘01. It had every gauge and the ultra rare level 4 black interior.

I’m a picky bas**** and really want something as close to how this came as possible. I can absolutely polish and save the muffler but the elbow is a bit too damaged for my taste. I’d prefer the new muffler. I was shocked when Watt’s didn’t still show the shiny muffler in the b model shop. I did buy the 5” muffler on Iowa80 for the Rubber Duck Western Star and it is perfect. Want to stick with 4” on this puppy.

They used to be listed under B model parts but not any more.

Is the 8.5” diameter chrome muffler with 4” inlet/outlet still available anywhere? Also, trying to source a chrome R model elbow.

Move this ‘87 R686ST from the Chicago R model category to the St Louis R model category. Former T&W/Naperville Ready Mix tractor #423. 300/air 6 and getting ready to undergo some restoration work.
