I will have to fab up mounts to get up to the Eaton mount area. The frame mount ledge is about the same as upper mount holes in Triplex. The Eaton is way up compared to those. The pattern is completely different between each . See sketch. Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted 4 hours ago Author Share Posted 4 hours ago The top of the bell is still just below the floorboard so the mount will be going down and back from the mount point on bell. I don't see an issue with clearance. Time will tell, I have a welder....it will all fit. 1 Quote Larry 1959 B61 Liv'n Large......................

mrsmackpaul Posted 3 hours ago Share Posted 3 hours ago I have noticed in Australia when RoadRangers/Eaton are installed in Macks aftermarket, a rear transmission mount is also used, these range from a propper engine mount rubbber deal to a section of leaf spring out of a car or pickup as you blokes call them These might be only 2 or three leaves, I wonder are they really needed or not ?

I don't see an issue with clearance. Time will tell, I have a welder....it will all fit. Not trying to say it will not work, just wanted to point out somewhere to check. The new mount is in a "different area code" as you put it, so needs checking, which it sounds like you have done. New things in different real estate is always a concern. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75768-300-rebuild/page/14/#findComment-587909 Share on other sites More sharing options...
Joey Mack Posted 3 hours ago Share Posted 3 hours ago Paul.. The single leaf spring at the rear of the main box was used here as well. Ive seen it in Ford's and Freightliner's, I think Int.'s also. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75768-300-rebuild/page/14/#findComment-587910 Share on other sites More sharing options...

Paul Generally, here if the rear mounts are on the engine 1/2 of the bell, a rear transmission "leaf spring" type or rubber bisket mount is used. On set-up's where the rear mount is on the transmission 1/2 of the bell (thinking Volvo/White) then there is nothing at the rear of the transmission. It may have something to do with how much weight is cantilevered off the back of the bell housing, esp when aluminum housing are used.

It looks like it had something bolted there and this was in a power unit, not a vehicle. 1 Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted 1 hour ago Author Share Posted 1 hour ago I am working on rolling in new mains. Question for FJH or Joey: The thrust brg on the cap side. Should it rotate slightly? The brg seems to have a slot machined in the bottom where it can rotate about 3/8"(width of pin) over top of the pin. Looks machined but the pin itself is worn on that side also. Coincidence? Back side is not cut and only wiggles a touch on the pin(which is still round and not worn like this side). Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted 1 hour ago Author Share Posted 1 hour ago Duh, guess I should have dug out the NEW thrust washers. No slot but does come with one new pin. Guess that answers my question. 1 Quote Larry 1959 B61 Liv'n Large......................

Joey Mack Posted 1 hour ago Share Posted 1 hour ago Yep.. it's worn and does not move when new. Im guessing its worn on the side that takes the force of releasing the clutch. Does the fork push the throwout bearing? Once again, just curious..

Joey Mack Posted 1 hour ago Share Posted 1 hour ago It looks like the crankshaft did not get scratched by the thrust bearing, judging by the condition of the thrust bearing friction surface. Are there oiling grooves in the new thrust bearings ?

Freightrain Posted 52 minutes ago Author Share Posted 52 minutes ago I was wondering myself how the front side got wear but it is a PULL clutch..... Ah ha. I'm sure they pushed on the clutch at every start. Even dead cold and 10 seconds before it gets oil pressure. I learned 35 yrs ago to not push the clutch on start. My hot rods had 3000# clutches and a dry start would just eat the thrust up. I broke a lot of linkages. Even today, with the super light clutch in the race car(two fingers will push it to the floor)I do not push the pedal to start. Now ever vehicle has a safety switch to keep the brain dead from starting in gear. I do the shifter wiggle 3-10 times before I ever push the button. The thrust brgs are nice, no damage on surfaces. I drilled the old pin out and press in new one. We are good to go. So far only the center main had a single dirt scratch in the brg. The rest are smooth and minimal wear. No brass showing. I'm done for today and will install this and finish up the last three in the next few days. Yes, the new and old had vertical oil slots in them. Thanks Joey. 1 Quote Larry 1959 B61 Liv'n Large......................

Joey Mack Posted 44 minutes ago Share Posted 44 minutes ago Nice.... I like this posting. I am learning things from you. I am pretty weak with the engine you have, i say that because I have only built 1, 673. I studied my book hard. But, of course E-7 + E-Techs are what I know fairly well. I have seen many similarities in how the engines were designed, of course the E-Tech block is its own kind.. Thanks Freightrain...

Joey Mack Posted 19 minutes ago Share Posted 19 minutes ago I do have another question... was there a snap ring on the pilot bearing? Im asking because if it was there but shouldnt be and the trans mounted would push the crankshaft forward putting excess pressure on the front thrust bearing causing that wear? I almost made that mistake in an Int. 8100 . I put a clutch in it, but couldnt get the trans to mate up, by 1/8". Somehow i figured out the snapring i left on the bearing was the issue. Removed it, seated the bearing.... good to go.... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75768-300-rebuild/page/14/#findComment-587926 Share on other sites More sharing options...
Freightrain Posted 19 minutes ago Author Share Posted 19 minutes ago You are one up on me....this is my first! It's just an engine but they all have their quirks. I just keep reading the manual to get ahead of things coming up. Guess I didn't read far enough 😆. Didn't dig deep enough into the parts box to see them on the bottom under everything. 1 1 Quote Larry 1959 B61 Liv'n Large......................

Jojo "pretty weak"is associated with lifting weights. building engines doesn't matter if one or ten are built. each one becomes a learning experience. to the builder. the self willingness to learn more is the difference between a "mechanic" and a professional engine technician. fortunately this site has many professional technician for us to learn from. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75768-300-rebuild/page/14/#findComment-587928 Share on other sites More sharing options...
