I also had a pair of 10.00X15 lowboy trailer tires on the steer axle of my backhoe which they served very well. Rob

Tonight I pulled the charge air cooler from my "new" R690. It has four tubes smashed and one with a hairline crack. I don't thing the smashed ones will be much of an interference as the tubes are near an inch deep and only crushed about 1/4 inch, (or less). The CAC was dry in the inlet as was the discharge of turbocharger housing. Will need to order a mounting kit as the bushings are beat to death. When this thing either comes back from the radiator shop, or is replaced, I plan to install a pressure guage into the intake manifold. I ran the truck in the shop with no piping on the turbo outlet and the flow is good at idle, and builds good pressure when restricted by hand and the engine revved. I'd like to see what boost the engine is actually making. The engine seems to be so far down in power that something must be amis. Planning to check static timing over the weekend as this engine running at idle is much quieter than anything else I have that is diesel powered. It's possible the timing is retarded. Rob

They are on my winch truck in 11RX24.5 size. They appear to be good tires. Rob

If you ever read instructions that accompany booster cables they always state to connect the cables to the depleted source first, and the boosting source second. This is due to sudden inrush of current and rapid heating of the cell plates within the depleted batteries upon connection. The battery that exploded had a partial internal short causing the same thing with catastophic results. Lucky the battery box was covered. Rob

Years ago I took a Brockway cab apart to put on an F model Mack. It can be done but it really is a lot of spot weld drilling to not destroy them as the basic "shell" is near the same. Rob

Musta been easy to post on ATHS then??? Was over there for the first time in more than a year to check the post(s) concerning PeterJ whom is a very nice guy and supporter of the hobby. Rob

This site is THE authority for Mack. Why post anyplace else? Too much like a communist republic over there, (ATHS) for me. In the words of another member referring to the ATHS board; "What a bunch of pricks"! Good looking engine as it is apparent you have taken great care to get it that way. Rob

We should all get T shirts like this as it about sums it up: Rob

The "flipper" valves are still readily available through Bendix. Early versions used the "flipper" valve for the tractor protection and I think it was 1966 the button with 40psi pressure release was mandated. Rob

I kinda liked them myself. I replaced a hood, left fender, left front door, and straightened the rear on the left side and what a joy it was!! People that owned it were assholes from the word GO! Beautiful car that was always gargage kept. http://en.wikipedia.org/wiki/Rolls-Royce_Silver_Cloud Rob

Was that a "ghost", or "cloud"? I've worked on both through the years. Quite impressive in the fit and finish of those cars. Rob

Hi Larry and Ken. I knew you guys are somewhat close but don't want to put anybody out. Larry has picked up a couple items for me in the past so don't want to be a bunch of trouble again. I will be through the area on my way to Lititz with the "Trusty, yet Crusty" Dodge, (so I know I'll get there) dragging my car hauler full of parts for David, (hopefully) the last weekend of this month. The seller is not pushing me to get the thing moved but did express interest in having it out of the way. I'll email them to find out for certain. Thanks, Rob

This is true. However the tractor protection valve also charges the air tank on the trailer. If you have two air lines for connect to a trailer, one of them, (red in color nowadays) will charge with air from the tractor as soon as the tractor protection valve is actuated from "emergency", to the "normal" position. If there is a trailer attached and the lines connected, this line charges the air tank for the brakes on the trailer. The other line at this time only supplies air to the trailer when you depress the foot brake. This line at this time becomes charged with air going to a relay valve on the trailer applying air from the trailer tank to the brake chambers. When you let off the brake pedal, the charged air line from the application of brakes, (blue line) exhaust under the truck, and the relay valve on the trailer exhaust the line pressure that was built up to apply the brakes. The tractor protection valve is there in it's form to disconnect the trailer air supply in the case of a massive air leakage on the trailer, or the interconnecting hoses. Rob Rob

I have purchased a one end jack in Columbus and really could use the help if someone could grab if for me till I come through the end of this month. I would imaging it would be best to use a car hauler, or lawn mower type trailer as it can be a few hundred pounds but does roll. The seller can load. The seller really would prefer it gone before I can come by. It is already paid for and doesn't need to be stored inside as it will be rebuilt once I have it anyway. Thanks, Rob

As most of you know I work for the FAA. I personally remember well the tremendous effort to get aircraft on the ground all over the country that morning, and the ongoing effort to ensure safety with our transportation infrastructure. Rob

I could "head it up" so to speak but would prefer someone more in the east locale perform the service. Rob

If the chassis was built as a tractor, it should have the normal/emergency valve also. If it was built as a straight truck, it could, or could not have the normal/emergency valve. They were optional.This is called the tractor protection valve. Rob

My 72 R model has black knobs on the rear wall of the cab; one for tractor brakes, the other for trailer air supply. It does not have front brakes so there is no dry/slippery road selector. Rob

Yessir. That fitting is a pressure regulator/check in the return line to tank. It maintains fuel gallery pressure within the pump. Rob

Scraped off some of the dried "goo" on the left side of the transmission and it is stampedT2100. It also has a dry clutch but the aluminum casting has raised letters stating to use ATF as the fluid for one of these things. The round, raised boss would be bored and threaded with a plug if it were a wet clutch. Found a busted tube on the CAC and several tubes that are bent shut. Looks like impact from following a tractor or combine too closely during harvest. The radiator core while complete, is weak although it doesn't leak. The engine really smokes black when accelerating and shifting gears and makes almost the same power as my 58 B61 with a 170hp engine, LOL. Also discovered the rears are 4.17's and it's on 11RX22.5 radial rubber. Rob

Well shit. This news takes the wind outta my sails. Of course we will keep him in our prayers as he is a great guy to be around. Rob

My trucks, (B models) that only have a single filter are plumbed as I said from the tank to the transfer pump, then through the filter, then to the fuel pump gallery. My R models all have two filters and are as rhasler states. Think I was confusing with my original reply. The most rearward port on the pump itself is the overflow that returns to tank. Rob

If I remember correctly the suction line from the tank goes to the transfer pump in your photo. The discharge of the transfer pump would go to the inlet of the primary filter, the discharge of the primary filter is to the inlet of the secondary filter, the outlet of the secondary filter is the inlet for the fuel gallery of the injection pump which is the forward port in your photo.

Got out and tested the splitter today. This also brings up another question. Is there any way to make the splitter operation faster on both the up and down shift? I have a 5000 series slave valve and 5/32nds air lines to everthing running to the shift knob. The high/low range is very quick in operation but the splitter seems to be a little slow. I don't notice any noise from the transmission at all. Truth be told I also don't have the mat back in the cab, nor headliner installed so there is quite a bit of road noise permeating the cab. This could drown out any road noise. Rob
