Depends on a guy’s budget I guess buddy!😀
-
I have heard that you can modify the 13 knob but have never done it myself!
-
Nope! Shift knob is your changed item!
-
Dodger Did you solve this ?
-
Picture would help
-
Well don’t be driving around with no brakes check it out!
-
How far is it coming out? Any farther than 2 inches with the spring brake applied then your not adjusting properly!
-
Joey do you have any pictures of these tools I have built a half dozen of these an the only Tools I had were the ones for 92/93 had know idea at here were caging tools! guess I just made due!
-
Yup check wiring to the timing event mark er rear side of the fuel pump!
-
Push down and counter clockwise 1/8 turn if I remember correctly!
-
yup also anti compound check
-
Dodger did you get the clutch adjusted right ?
-
Need to take in all the evidence before you pounce!
-
just something i suggest trying is on level ground release the the spring brakes see if this changes the leak at the treadle im thinking check valve here just something to rule out before replacing the treadle!

2000 Mack RD 688 Starter issue
fjh replied to cfd511's topic in Electrical, Electronics and Lighting
Check both big poles on the solenoid should have power on one and not on the other! Also is the power wire touching the trigger wire on the starter? -
Yup I'm getting a bit rusty with this stuff been away from it for a bit now ! So I'm glad you chimed in! I'm relying on memory and that's not as good as it used to be!🙄
-
I would make sure your front mount is the the same your getting into the years where the front mount was changing to a two bolt mount from the trunnion arrangement on the newer unit! otherwise this would bolt in! also does the newer truck have a charge air cooler in front of the rad?
-
I’m sure you can if you can find one that puts out 20 or so psi!
-
He has been fighting with this truck for awhile now ! From what I understand the EGR is capped off! From my experience should throw a code for egr flow but not effect or derate the engine How ever this may have changed in certain years?! At one point it was pulling well ??? not sure if this has changed! He claims the turbo is stroking completely on startup! with out the boost gauge it is hard to gauge whether its getting all it has! Also its hard to know if the turbo blow off or by pass is stuck open or getting weak! I understood that that valve started bypassing at 20 or so psi!
-
It pays to not get too trigger happy!And not to over think stuff! Weigh out all the evidence and proceed with caution all of which you have done! Also very happy for you! Now all ya need is a turbo hopefully you’ll find the parts and all will be good! While you got it apart do a valve set and tiddle things up while waiting for the turbo!

71 R Model 237 Injector pump problems
fjh replied to Mark Bertone's topic in Engine and Transmission
Please post a pic of the fuel pump! The rack may be stuck! -
Yup if it’s a bad valve you will hear it! And it will smoke or slobber fuel from the bad hole! You will also know which head to pull if indeed you have an issue! just sayin
-
bro it was running when you turned it off! Correct? Anyway only place i can think off is valve seat and or piston insert or ring ! Liners are cast ! the shape is confusing ! A melted piston would have been running bad! a broken ring is not that shape! Don't have any answers for ya! I would run it my self as Joey suggested ! The damage if any is already done!! some one along the line has accidently left something in the exhaust in my opinion ! a piece of old gasket or something!
