Waking up the E9
AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
I have to look into one of those when my setup starts giving me problems. Sounds like it is totally adjustable and can roll on the pressure with RPM. My leg gets a workout holding down the 4000lb one I got. Not something you want to drive everyday but it dose the job. You running Rockwell lockers? I got them on air and is a nice setup.- 55 replies

AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
That's a chunk of change!! What is the torque rating? I get that it is reliable but is it smooth like a metallic puck or is it like a NASCAR or drag clutch, in or out, no feathering unit. I have had many differant ones over the years. In the trucks it is smooth but my race car it's ether disengaged or all in and no in between. Can you inch up at a light with out chattering?- 55 replies

Hay Albert, What did that clutch put you back? My twin disc is good for 4000 ft/lbs but after these mods maybe at its limits. Was that EZ to install? How's the pedal, a little stiff? Can it be driving daily? Cool looking unit!!- 55 replies

watts wiring
AZB755V8 replied to Willie dog's topic in Antique and Classic Mack Trucks General Discussion
Did my several years ago. Go to the Mack museum site and look at the list of vendors. There is one that does original wiring with the cloth covered wire as used originally. I don't know if it is as pricey as Watt's but it is probably were Barry gets his anyway. Take a minute and look it can only save your money. -

Getting back to the topic, major problems. with the old Mack v8's. 864 injector pump, junk! Cracking heads, bad design with injector nozzle about 1/4 inch from the valve seats. They even had an expansion joint machined in to prevent the cracking. dropping valve seats and valves. Blowing head gaskets, They need constant re-torquing. Coolant leaking around head bolts. Freezing and hoping the head off bolt. Main bearings, need to roll in a new set about every 150K miles. Smaller than the E9 main bearings. Don't have them against the governor up a hill and let off going down the other side. Valve seats cool down and fall out if heat goes out of head to quickly. Needed more maintenance than and I6. Was a one driver engine. Don't give one to the new kid... rods out the side.. Needed warmed up good before putting a load on it. Weight, about 600 lbs more than I6. The E7 was one of the best Mack engines in al around good power, low maintenance, and durability. Don't get me wrong I love these V8's but they are not at there best most of the time for many reasons. Nothin sounds like one... Only thing as good sounding is a Supercharged 275 Cummins at full tilt...

Waking up the E9
AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
Thanks, really did not know that. Intercooling would be much the same as an E9. Both engines have the same turbo and intake layout. There is a few inches differance in location but tubes could easily be bent up. I don't know if I would be turning up the pump and intercooling an 865/866 though. The heads are 2 valve and prone to cracking into the exhaust valve seat and dropping inserts. I had to go through a pile of heads to get a good set. Parts are a REAL issue, I have both engines and am just happy my 866 is as good as it is. It is rebuilt with less than 1000 miles on it. I did it back 20 years ago when Mack still had parts. Used standard main bearings and there were 3 differand standard bearing listed but only one set avalible at that time. Oil pressure is OK but runs 35-55 hot, almost 75 cold. Intercooling would get you about 40-50 hp but probably at a cost in broken parts. Just my two cents worth.- 55 replies

Waking up the E9
AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
That's funny... When I rebuilt the 866 with 27 degrees timing. I thought it was a lot. The engine I started with had 3 cracked heads!! I had to go through another 12 heads to find a good set. ALL 865/866 have at least one or two cracked heads no matter what. Maybe that is why Mack took a lot of timing out with the E9. Thats another question for Dale when I see him,TIMING.- 55 replies

Al, Found Steve's notes on my engine. He was not into custom parts to much and used the military spec stuff. The injector tips are Bosch 0 433 171 341. Curt Price did my pump at Antrim, A stock motor runs best at 19 degrees timing as Steve states but I think I have around 25 degrees. What are you guys running on timing? My old 866 in the B755 had 27 degrees on the valve cover tag as spec. It sort of clackes a bit, I think it sounds good with a little "hunting" going on, about 50-100 rpms at idle, just a slight rock if Ya Know what I mean. That pump, injectors were done at the old R&R Mack in Twinsburg Ohio. Turbos.... All I know is bigger is not always better, more psi over a larger rpm range is for me. Pullers I think like it all at top rpm, is that right?I got two small turbo's on one of my cars and it is a rocketship beteewn 3500 to 7500 rpm's- 55 replies

1947 MACK LJT, HEADLINER KIT?
AZB755V8 replied to ljmack's topic in Exterior, Cab, Accessories and Detailing
I got my LT kit from them last year and it was perfect. It's a shame if them quit making them. They did have the patterns as of a year ago. If needed in still have my old interior panels that are in near great shape for a restoration but not perfect like new. If interested I will get some photos. -

Your Superliner really runs,WOW! Is that with a 13mm V Pump? EGT gets to 1050-1100 under load but I have not had it pullin or draging myself yet. It Is goverened at 4500 but I have not had it there for more than a second or two playing around. No I do not have stock heads on this engine. Francis is doing another set for me now for the other engine to. I still use this truck and turbos comin on at 2000rpm plus doesn't work for me now. Where are those 4.1 comin in at? I should talk to Dale about it in a week or two when I am at his place.- 55 replies

The light weight B's are not that uncommon. there were more of them out West. That is were I found the two that I have. They are lighter but at a cost. Remember most of them were built with surplus war scrap aluminum. Most of the castings are weak and cracked if you can find them today. My B-75 radiator is polished and you can see about 3 different shades and mix lines in the castings. The LTL's had a lot of aluminum in them. There are over 140 aluminum pieces that totaled 2000lbs weight savings in the "L" version. I don't think there is one left that has all the aluminum intact now. There has been several aluminum front engine mount put in mine all cracked, cracked though once and dropped the engine, tore up the fan shroud with the fan, rear aluminum cross over with the drive shaft last time. One thing, think twice about those original aluminum air tanks. I have several and did not use one. They are SUPER THIN compared to new tanks and all have corrosion, inside if not on the outside. My LTL had them and now has steel ones, the B-755 has new Aluminum Pete tanks. The old tanks are dangerous after 50 years. Don't mess with old aluminum air tanks if you intend on driving it.

Couple of in process photo's almost ready to roll the Superliner out after two years in storage. Top one is before storage, bottom two dusty and being worked on. New 6 inch pipes, chain locker, Radiator, intercoolers, seats, interior, train horns, chrome, powder coating, engine mods. I know of the Red MH "Thunder Dog" but have not seen it in years. It was an Amtrim modified truck and did well pullin out East.- 55 replies

AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
She really lugs starting in that gear but you maybe right, that only give me 3 shifts in a 1/4 mile. I don't get to 18 before that, top end is scary. It'll do an EZ 125mph on 65 mph rated front floats... well she is good for more with .78 over and 3.76 rears but tires are an issue. RPM's are governed at 4500, where you at?. 13mm Pump was done in 2004 at Antrim with sized nozzles, have the tip spec. but need to find it. It has 60-62psi boost up to then. I can't knock headers in an E9, but don't understand how they can work with all the back pressure before the turbo. All the exhaust has to go through those little 2" cross-over tubes and turbo hot side or do you use bigger, tubes, housing? I had to modify some stuff to get the H5 Holset to fit right and get the blanket on it. It was the biggest housing and mount I could fit. I still use this truck to pull a drop deck so I need the turbo at 1500rpm's. I maybe as far as I can go and still use it for both fun and work. That it why the second intercooler I can turn on when needed for 125 extra HP. I really have not heard of getting much more than 65psi boost out of a single stage turbo set up. To get more boost, compounding turbos, heavy engine mods, a lot of tuning and Big Big Bucks!!! PM me if you want to share.- 55 replies

AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
Got to admit your truck moves out like few I have seen!! Have to line up side by side some day. That is where I was going to start but that is 3 Hi on the low side, on an 18spd, 3.76 locker rears, then up from there. Man I have an Old H5 Holset 3.6@60psi. It comes on at 1800rpm's. what the heck will that 4.1 come in at? Will it be making the same boost? I have Frances doing some work for me now. He said I could go bigger but the only thing was raising the rpm range and the same 60psi. Thinking of going with 14mm plungers with the inline, I like smoke!! When we test drove it a few years age going 60 them hammers it to 85 in about 3 second, Dan said the speedo was right and take a look at the car we just passed. All I could see was smoke ,sorta felt like James Bond with one bad ass smoke screen with the car breaking though about 200 feet back.- 55 replies

AZB755V8 replied to AZB755V8's topic in Antique and Classic Mack Trucks General Discussion
That's what I was thinking, She pulls like a 14.xx sec. but a time slip is proof, not just talk!! With the new intercooler low14's. I'll see in a month or two. I got a Mack 18 spd but will be skipping about every 4 gears, shiftin cost time. There's a good 2000 rpm range to work with when she's on the turbo. Did you get a new pump set-up recently? What are you runnin?- 55 replies

I have used GPS on the phone in my other truck for speed, The Speedo was off about 11mph I found. I am putting all new gauges in this truck, a GPS speedo was at the top of the list. My kids do the marked off 1/4 mile thing with their car friends, I just have to find out where it's at! I go to Wildhorse Strip, its only 20 minutes from the house, gota be a dad and promote the right (safe) way. Plus have to trailer my cars anyway.- 55 replies
