Go in at night...

Ray hows the MPG without the stacks....it looks so bare without them!!!!!! LOL

yea we rolled it over to the factory setting of 19* BTDC. yes we are assuming the timing was at stock and never adjusted, We backed off the 4 bolts that hold the pump to the gear. Held the pump still with a wrench while we barred the engine back to 25* BTDC. then locked the 4 bolts back down. and put the timing cover back on. here is the pull we did last Friday. She ran a little better and the RPMs did not drop as much when under full load. we made a full pull, 309' !! http://youtu.be/rPbOCN1aDDg

what did I miss???? Trent

Pig pen......

wow! good find....whats the plans for it?

Yep They have some of the best "fast food" Pizza in Chicagoland. And whats best is you can eat on the south side or out in the far NW burbs and it still tastes the same! Keep me posted! FYI sled pulls are tomorrow night at Lake County IL Trent

Rob I am pretty much traveling every other week untill the end of September. just let me know when you think you will be up this way. Weekends or week nights are best for me. Trent

Ok think I got it done last night. I was able to bar the engine over to the factory 19* BTDC.( Pointer on the 19* mark on the damper) I then had a friend put a wrench on the pump nut, we marked a refrence location with a scribe. I then slowly bared the engine to 25*BTDC and locked the pump back down.

now that was Some Funny stuff right there... "sign up today and you get a Chain drive wallet" LMAO... "you should start with a volvo or a Freightliner and be someones dog"

thanks for the into guys I have been so busy that I have not had time to make up a tool. One question I forgot to ask. Does the pump (when engnie running) turn in the same rotation as the engine?

What I laugh at is that I see more truck fires nowadays than ever before... just this last trip to canada I saw 2 trucks torched to the ground. last trip to Long Island one truck up in flames. I also see more trucks rode off into cornfields. last 2 trips I saw about 5 trucks parked or on their sides. makes me wonder how hard these green drivers push themselves to make beer money and fall asleep at the wheel. Sad!

I always thought the 5 speed was easy and the eaton fullers were hard to shift. The macks altho rough around the edges had a positive feel to them when they were going into gear or not going. the eaton fullers will only go into gear if timed correctly of scratch/bang into gear if you were off. I would rather feel the scratch and not go in than it fall in with a bang!

With 4.17 rears .....1st and 2nd are slow ...3rd about 27 mph.4th about 40 In 5 th you max out at 62 mph at 2100 rpm. This is aprox numbers. you have to use the whole rpm range of the engine...rev it out and shift at 2000-2100 and it will fall back to 1200-1300 rpm when you grab the next higher gear. The 5 speed has wide splits but is easy to drive with limited shifts needed..

The 8 LL is eaton??. It's not as strong as a Mack 12 but the splits are wide and the 300 maxidynes loves that.

You have a 5 speed that is direct in 5th. You need an over drive trans. Look for an 8LL or a Mack 12 speed. Both have wide splits for the maxidynes torque curve and a over drive that can get you home in a hurry. That's my .02

Thanks very much for this info. It sounds fairly easy after you have a tool made up. I will get some pics when I have it set up to make sure I'm doing it right...its great to have people such as you with this kind of knowledge on this site. Can't get that kind of help in a book. Trent

Ok I under stand finding the 25 deg mark on the dampened,. And then Lousen the 4 bolts on the pump drive coupling.however I can see that the coupling has slots that only allow you to advance/ retard the pump about 30 deg. How do I know when the pump is obtaining port closing?will I feel it or do I need a tool to know. I think it's an ambac pump. Will have to get a pic soon. Thanks for your help

Sled pull season is here and want a little more power. We removed the pump timing cover and see it can be adjusted. There are no marks on the gear just slots to pot the bolts in and adjust. I was hoping I could just bring it to tdc and advance the pump to say 24-25 deg and lock it down. Problem is I don't know where it will be at? What's the deal.

1st direct,rev out gear,flip to hi,release throttle,let rpm drop and fall into next gear, grab throttle and rev out gear, flip into direct, release throttle, move into 2nd hole...repete..

The kits are hard to find. Best bet would be to search for a turbo rebuilding shop and ask them. That's how I found my rebuild kit for my Mitsubishi turbo on my Toyota ...may try precision turbo. I think they helped me. Make sure to check the threads on the shaft...i recall that the compressor side Sometimes are reverse threaded!!

im sure glad I dont run more then a few days each month. I do my normal drive 14 hrs and then sleep 8-9hrs then drive another 14. East coast in a day West coast and southwestern states in 2 days...no bull shit government trucking here. On the other hand the old HOS rules did protect drivers from company abuse. so they are needed. the HOS rules today are a joke. too hard to follow and understand as each state seams to have a diffrent understnading of them. Im kinda wondering how these new electronic logs will be. part of me says it will just be that more simple to adjust the logs to my driving style and the computer will tell me where I made an error. Just like every new lock, there will be guys like me picking them....

great pics thanks for sharing!

200 sounds normal to me in hi heat weather. A few simple checks would be to check belts and listen to hear if the fan clutch is operating. If that checks out test the temp gauge with a new sensor or gauge. You can also remove the water pump to check the blades are in good shape.

I thought it sold and went over seas to a collector? I saw it at one of our local shows years ago but havent seen in a while?
