He was on here talking about it a while back. Think it has some engine issues? Haven't heard about it for a while

If i can ask...What was wrong with the tar paper. Mine has been holding up great for past 3 years, no smell after a few weeks, truck is parked out doors all the time?

I used dynomat on the firewall only, everything els was the foil backed asphalt roofing material that comes in a roll. Dynomat is pricy to do the whole cab in.

Yep did the same thing, rubber paint,dynomat,carpet on the firewall. Also did the doors,rear wall,floor and roof, made it real quiet, still want to make a flat firewall panel that is on the outer cab to further silence the road noise.might even put that hood mat stuff under the hood. . Biggest noise issue on my cab was from the firewall/ steering shaft hole and gear stick holes. Even with my straight stacks It's pretty quiet now.

Your cowl on the rd will be similar to a super liner, a r model is a completely different cowl because of hood lines. Western and value line hoods should interchange, Western,value liner hoods might share the same cowl lines as a east coast r model. Just that the western,valuliner cabs sit up higher. Hood latch of the cowl area vary as well from each model, year, air ride cab etc...

My 77' RS700 has the Fiberglas lower fender. only down side is mud will run down the inner fender wall and get the fender dirty. I need to make a panel that will keep water and mud on the inside. Same with the gab between bumper and front of fender.

I'm the same way! Sounds like a rotational vibration. Clutch,dampener,bad mounts, but almost every r model I drove had a slight vibration at some point of rpm or speed. Might be the nature if the beast?

Did it vibrate before the new injectors?

That R jones Mack is very nice. Love the metallic blue and aluminum is always shiny. Saw it this time last year running 290 and it looked like it had just left a truck show. I would love to catch a good photo of it, words won't do it justice. I'm more on the northwest side of the suburbs. But we have a few hills that start out with a stoplight. Rt31 and Algonquin rd rings a bell. 1/2 Mile long 6% pull ( big for us flat landers) and at the top was the rock pit entrance. It was a race to get in front of a few trucks if you had the power. Remember running with a bunch of fleet spec remodels. 300,6spd,4.17.... Just watch the stack of the lead truck and if you made your shifts at the same time there everyone made it to the top at the same speed, nice and easy..

Only had 3 pics. The damm was a ex cement truck converted to wrecker. Not sure where it was sold to they only had it for a few years. I think it was to much of a truck for what they needed. They run a big fleet of recovery units for the il tollway. Mostly on road rescue. If I recall it was a 300 with a 6 speed.m

Here are some old ones.. sand.bmp

That's a blast from the past.. I remember when Lenzini was an all Mack fleet...I live 2 min from their yard. Now it's all kw and Pete..

If you can open the hood and hold it at the rpm with vibrations. Look at the engine to see if it's "jumping" if your rear mounts are bad it can cause the vibrating movement. And yea, 30lbs of boost is on the strong side. You should be able to keep up with a 427 untill the top 2 gears. Might be able to hold him all they way.

The balancer does what it sounds like it would,....it Balances the vibrations made fromthe rotationg mass of the motors moving parts.. Think of it as a counter weight to off set vibrations. Picture a 5 lb weight on a chain. Swing it around and you will find you are leaning backwards to off set the outward pull of the weight. The balancer is made from rubber and steel. Some may have liquid in them. As the engine turns each cyl fires off and sends a shock wave thru the crank and is absorbed by the balancer . A bad balancer may not be able to absorb the shock waves and thus you feel the vibration more.

Wait till vinny sees this!

He texted me this morning. We're trying to meet up so I can hand off his landing gear that I brought back from Queens N.Y this summer. It's been under my trailer for. 5 months now and they are about to get snowed in!

if you can get good hot heat in the cab, with the fan on Hi. that tells me that coolant flow should be working and the water pump is pushing coolant around the cooling system. Does sound like a bad T-stat.... remove it and replace while your in there. and if you want test the old one in a pot of water on the stove. you should see it open up as the water temp is getting hotter. if it does not open,you found where your problem was! Let us know.

Don't think so but check it anyways. If i remember correctly The water system is a bypass system it filters coolant but also let's water by pass it if the flow thru it is restrictive. You need to check for coolant flow and see if the thurmostat is opening. Does your cab heat work?

Bad water pump Bad thurmostat Sounds like you don't have flow or the thurmostat is stuck shut

From what I have seen on a 89 super liner with 440 V8 The tach drive Seam to fail all the time. We replace one every 5 years. Air throttle was a joke. Exhaust studs can be a pita. Other than that parts will be harder and harder to find. The truck had 425,000 and needed a rebuild but the owner was never good at maintance. Real bad infact.

What's your 4 axel tractor weigh? buddy just bought a 4 axel Pete to heavy haul with.

Good looking truck, great drive train set up. And has a nice wheelbase. A Common rear with that trans was 3.87 or 4.17 will put you around 75 mph.

The ones I remember were black boxes about 3' by 4" and bolted to the door panel, think they went right over the window crank rod that sticks out of the panel. In a R model your knee would hit it all the time if in the passenger seat. Forget about using it on the drivers door!. Thats how I remember them. CH cab might have more room but they are a ugly add on if you have a nice interior...

I would be intrested to see how powerfull it is. the window felt can be tight and is a PITA to roll up by hand on some doors.,,

Looking good. Nice specs as well... What color will you paint it?
