2 Stick 12 Speed?
fjh replied to Lmackattack's topic in Antique and Classic Mack Trucks General Discussion
Answer to Glenns question, yup the countershaft bearings! answer to Trents question Air shift can convert easy remove the detent ball under the lid and your good to go! Most have the hollow countershaft for the mack pto but you should look for your self the case is usually stamped with a 0 or pto on the bottom that dosent always mean its there! Youll like the 12 speed with the exception of the 5 hi lo split they grind a bit! Theres only one or two guys that walk the face of the planet that can shift one with out grinding! -

2 Stick 12 Speed?

Good trans for the most part! If you do a lot of backing up on steap grades they tend to take out the back bearings We use to replace the bearings once a year in off hyw gravel trucks as a maintanance item, takes about an hour! depending on ptos! -

the second stick is the deep reduction they simply put an air shift on it for certain models! That made it available in the MH when it came along! -
Yup no problem!Thats what this place is all about!
-
;No prob ,were just trin to help right .either way he'll get there!

Nope ! you can't hurt the injectors unless you get really aggressive. Go thru the valve set again somthing is messed up !Follow one or both of the afore mentioned instructions to get your self back on track!If your stuck for Valve set marks on the fly wheel , the set can be done on overlap on the rest of the cyl's as I discribed earlier, in firing order . 1 5 3 6 2 4
-
You got smoke that means ya got fuel!The valve set sounds suspect!With the lids off check for overlap (valves rocking) on # no six then set the valves on one and go thru the firng order ,what your doing is confirming compression on one with this only use the pointer on the flywheel for V/S mated cylinders below If one is on compression six will be overlaping If 5 is on compression 2 will be over laping! 1 5 3 6 2 4

Ai 460- 05 Granite- Aftermarket Performance?
fjh replied to jm3isme's topic in Engine and Transmission
you might want to talk to thunderdog on the forum here he did some stuff to his it pulls OK now ! Drop him a PM. -
I got to beleive you will float valves with stock heads at 4 grand! Broken lifters were a problem with these on over speed 2600 maybe. but .at 4000 you'll have push rods thru valve covers in my opinion
-
No I think you may not be set right check to make sure you are on the right cyl when setting 8 and 2 are on the same mark. 2 should be on overlap when you set 8

We would normally quote 50 hours on the out frame and 10 too 16 RR

32 litre or quarts total 28 in the pan. If it has 3 oil filters (Deep pan ) it takes 48 in the pan 53 including filters The endless oil change your doing a n oil change every second day! -
You likly don't have to worry on the injector cup as it is the bottom of the head (cast) the injector is mounted in in a sheath pressed into the head.Yup ya did good I'll be puttin this one in my memory bank as I never would have thought a chirp would develop by an injector I have seen one stuck so bad the injector insert came up with the injector and had to use a porta power to pull it and of coase it was No 6 the hardest one to get to! Your Hired! even thou you are a PETE guy! We won't hold that against ya!
-
Wow! Good news! that would have thrown anybody off track, good thing you stuck to your guns and pulled the injectors ! good find Thanx for posting your fix! Lot Better than doin a Cam job!
-
Kool! You set the valves with the pointer located on the right front of the engine aimed at the damper the damper, The set is done in firing order 1548 6372 You need to set a 8 and 7 turn the engine to 8/2 on the damper if the valves are tight and are in motion as you turn the engine you need to turn the engine 360 same for seven .once you have set 8, seven comes up on the next turn!by pass 6 and 3
-
Bro your wasting time doing a valve set Yes Do the injector orings then pull the pan and look at the cam these Engines are time tested unlike the volvo mp engine they do certain things make certain noises this is a classic lifter chirp by what you discribe!50 pounds injectors 20 pounds or so on the lids 45 to 55 0n the jakes But don't bother putting any of it on till you check the cam! I only takes a half hour to pull the pan down worth the time as far as Im concerned!
-
Bro you need to address the churp sound before going after the valve set pull the pan and check the cam!That churp is likly a lifter or cam failing they don't always fail on an injection lobe!Injector orings can leak yes that is likly your leak!
-
By DOT limits here your allowed 3/16 at the bottom of the wheel tipping it with a bar! I would be more inclined to say 1/8 to be the maximum! Bare in mind to much wear can create unwanted tire wear!
-
Pretty much any range type trans you want to PRE SELECT the range the split is another story the split needs a low to no torque situation to work ,
-
The engine must have got hot(not on us)and cracked the valve seat. (NOPE its was a fairly comon thing ) Just happens! and usually the same way every time shut the engine off everything is fine ,Start the engine up Bang Bang Bang! anyway .As Glenn pointed out ,you do have 3 more heads to possibly do, But if you need a good runner we have a few! We just tore down a v8 got lots of parts Might even scare up a piston ,Phone Gary At Nanaimo Mack ( Vancouver Island) 1 250 758 0185 phone tommoro Gary is not here Fridays! He'll hook ya up ! Tell em Fred sent ya!
