1989 Mack mh613 Mack e6 350 4 valve engine fuller 9 speed on Mack 4.17 rears with bud wheels. Has pto but I haven't used it so can't verify it works. I bought the truck as a project truck but I'm going to go a different route.  $7500 takes it. Contact me if interested 239-410-1662 located in punta gorda FL 

And I have not hooked the airlines up to a trailer yet. When I'm doing this the trailer brake valve is out. I did push it in and the air was leaking down checked the junction block on the fire wall and it's still hot. Strange. 

Alright I'm finishing up my 1986 Superliner build and the red wire that goes to the brake lamps for the trailer in the trailer connector is always hot. The tractor brake lamps work normal. I know a easy fix would be jump the wire from the tractor brake lamps to the trailer red wire but I kinda want to fix it the correct way. Any help would be great. 

I replaced the entire headlamp assemblies. It's gotta be in the wiring. 

Ok so on my project Superliner when I have the headlamps on the inside head lights come on instead of the outside. Any one run into this before? The inside should come on when the high beams are activated. It's like they are backwards. Please help . 

Anybody? 

I'm looking for a superliner with a sleeper. Only requirements are e6 engine and cut outs on both sides of sleeper for dual stacks. Preferably a flat top sleeper but will entertain all available. Could be restored or need restoring just looking for a sleeper truck. Any help would be apriciated! Thanks Scott. 239-410-1662

Yes, it doesn't list a measurement for your custom application.  With a frame depth of 9.5", I would make a height gauge at 5 3/8" as a starting point similar to the ones shown in the pdf.

Have you checked the pinion angles of the rear axles?  Improper driveline angles will lead to vibration.

No I haven't. Not sure exactly how to do that but I thought by getting the correct air ride height it would correct that as well

Some more info.  A couple different measurements mentioned.

http://hr.mckenzietank.com/maint/Bulletins/16-sb136012.pdf

That bulletin still doesn't specify what the proper ride height should be with a 9.5 inch tall frame with al or al II suspension and Mack rears. 

 

 

 

So I did measure my superliner that's on camelbacks front rear from the top of rear housing on the left side to the top of the bottom frame rail and that measured 6 3/4 inches. Would it make since to set the air ride truck to the same measurement since it uses the same axle housings and the same frame rails? Again the superliners use a frame that's not as tall as a ch so there for I don't believe there is documentation on the proper ride height for this set up. And I don't think the Hendrickson suspension was ever available from the factory on frame rails as short as ours.

I think this may have come from our Wiki or a BMT poster...

I actually have this bulliten but our superliners only have 9.5 inch tall frames and that document states for frames with 10.47 inches and 11.81 inches. I'm thinking since my frame is not as tall those measurements wouldn't be correct. Agreed? 

Has anyone figured out the proper ride height on the Hendrickson air ride under a superliner? We recently put a ch air ride under ours and am getting s bad viberation. Any help would be great. 

Any idea where I could buy a new or used superliner fuel tank? My passengers side is rough and would love to replace it.

4.73 with a 18 speed....that think just not have very much top end. And looks like a Canadian spread as well.

Sure doesn't look like 227 inch wheel base either! I'm thinking more like 199!

I believe I know someone who has a really nice Superliner for sale with 199inch wheel base that would work nicely for you! Not to mention you wont have to worry about fixing it all the time like those Petercars!! Call me if ur interested ill cut you a sweet deal.

Here is a picture of the sub in the middle with my old drivers seat beside it. I have a seats low ride seat in it now as you can see in the pictures in the first post.

dds92780, the sub is a 12 inch subwoofer that I made a box for. its sitting on the floor with it slightly tapered up in the front and the amp is mounted on the back. The rears are 4.64 and with the 9 speed it does 75 mph on the top end. Gets 6 mpg all day. As far as the tractor total weight Ive never weighted it by its self but I would guess around 17k lbs. the truck is great and Ive replaced all kinds of parts on it. Just recently Ive replaced the clutch 2 weeks ago with a brand new one. I wouldn't be afraid to drive this truck anywhere! The truck came with no outside air cleaner. Some superliners did and some didn't.

excellent good luck,,,,we all gotta keep up with the times at some point,,,,nobody really happy about it,,,,im stuck in a volvo now,dont really like it,,but its got lotsa power,,,automatic,,,power windows,,,good heat and air..rather be in a U model...with the same specs.lol....bob

That's right. I'd love to keep it and it's a great day cab but I just need a little more now. I'm sure she will make somebody happy.

Sure is. Gotta little updated since then but it's the truck.

Your crazy to sell that thing! But I guess you have your reasons. Good luck selling her, and hope you don't grow to regret it.

Thanks... Yeah I need a truck with a sleeper and just don't have it in me to cut this one up. So she's gotta go. It's a great truck runs awesome!
