mechohaulic Posted May 2, 2023 Share Posted May 2, 2023 spent quite a bit of time checking U-tube for a demo of installing rear PTO; none to be found. tried to verify my failing memory of days gone by. going with idea changes have been made to design of transmission.

Bearing race is in the bearing cover, so pulling the cover allows the counter shaft to drop a little.. I can understand now why you made the comments of the countershaft dropping. makes much sense . which is reason i said DON'T DROP OUT of conversation. I actually confused the topic not realizing a change over in countershaft bearing set up. I didn't remember having to take side cover off. can see why now it would be done.

MACKS Posted May 2, 2023 Share Posted May 2, 2023 I have to check in my book because I thought my 12 speed has roller bearings under the rear covers and not tapered bearings with race..humm 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-530677 Share on other sites More sharing options...

Joey Mack Posted May 2, 2023 Share Posted May 2, 2023 so I saw a picture of the bearing, (in my head) in a 107(0) the bearings are pressed on the end of the counter shafts and the covers are flat.. I sprayed some PB Blaster in my ears and it loosened up some of the rust..

Joey Mack Posted May 2, 2023 Share Posted May 2, 2023 yep,, no need to worry about supporting the counter shaft.. Im glad you had that book..

mechohaulic Posted May 2, 2023 Share Posted May 2, 2023 no idea how much on a positive I feel now. most of night staring at ceiling trying to remember (yes i did). duel reasons =1- feared I misinformed someone;;2- constantly concerned of mind loss. cover closest is one I remember. by chance is there a picture of back side of transmission showing the aux idler shaft which had to be turned 180 for a pto to be installed ?

Joey Mack Posted May 2, 2023 Share Posted May 2, 2023 yes, thats a high dollar tool that grabs the snap ring.. you can grind a cheapo jaw puller down, and use a lady slipper bar (with care) to start the bearing out a bit or all the way as long as you are not gouging the housing. you can put a peice of sheet metal under the bar for protection. anyway.. those Kent Moore tools are crazy high priced...

Popular Post Joey Mack Posted May 2, 2023 Popular Post Share Posted May 2, 2023 MACKS,, ''You the man''.... That is the answer the 'poster' needed... all he needs is another top bearing cover and o-ring, and he can cap that lower counter shaft. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-530704 Share on other sites More sharing options...
mechohaulic Posted May 3, 2023 Share Posted May 3, 2023 between the pencil and pto shaft . the small shaft pushed in is the aux shaft I was referring to. center is 1/2-5/8th thread. when rear cover is in place, aux shaft in present position. when installing a rear pto that shaft has to be turned 180 degrees : actually sits inside the pto housing. I would assume that pto is being mounted on top right? THANK YOU ;Macks for photo.

Full Floater Posted November 25, 2023 Author Share Posted November 25, 2023 On 4/30/2023 at 4:28 PM, mechohaulic said: another thought based on yrs back ;the rear mount P T O 's on 6 speeds were constant run when engaged with truck moving or stationary. the side mount 6 speed pto worked off trans being in gear on main. pto speed depended on gear main was in. spreading asphalt was challenging :: truck had to be in low for spreading which was tooo slow for dump/PTO operation. thus the rear mount pto came to be. Just want to clarify "proper" operation of my rear mount PTO on this 6 speed. The Mack instructions on the dash, say to engage PTO with aux in N and main in gear. I'm thinking this was likely for a side mount PTO and maybe it was changed to a rear mount, later in life. As this one spins if the main trans is in N also, OR in gear. I don't notice any difference in hyd power or speed if a high gear is engaged, nor do I visually notice the PTO shaft spinning faster or slower. So with a rear mount, should I still have the main box in gear and aux in N? Or both in N? Am I to use engine RPM to spin the PTO faster if using a higher gear doesn't seem to achieve much.

Popular Post MACKS Posted November 25, 2023 Popular Post Share Posted November 25, 2023 Just keep the main in natural if dumping while not moving,if running out a load pick a low gear and go.. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-542459 Share on other sites More sharing options...

I would be in agreement the PTO was changed over to rear mount. dash instructions seem to refer to side mount. as with older PTO's the pto speed is determined by engine rpm's. truck is used by others , might want to cover or replace instructions with proper matching one. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-542460 Share on other sites More sharing options...
Full Floater Posted November 25, 2023 Author Share Posted November 25, 2023 Thanks. So both boxes in Neutral and increase RPM for higher pto speed?

mechohaulic Posted November 25, 2023 Share Posted November 25, 2023 only one stick needs to be neutral so unit doesn't attempt take off when clutch released. also one in gear is easier for movement after pto needed. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-542485 Share on other sites More sharing options...

Full Floater Posted November 26, 2023 Author Share Posted November 26, 2023 Ok thanks. And i'm assuming its safe to increase RPM to speed up the pto? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72803-6-speed-pto-pump-options/page/2/#findComment-542490 Share on other sites More sharing options...
