I've seen guys use a small air reservoir set to 15psi to atomize the fuel spray. I assume the nozzle is probably a "Delavan" at about 90 degrees spray pattern? Usually you want the engine cranking when engaging the heater system so the engine fires quickly. Rob

The transfer pump mounted to the rear of the injection pump pulls fuel from the tank through the primary filter. The transfer pump then pushes cleaned fuel through the secondary filter. The transfer pumps on the V8 engines are not really a pressure type pump but rather a circulator pump. They move fuel well if they are submerged. This makes the engine very difficult to restart when starved. I might have a weak transfer pump to suck the secondary filter dry before the pump can keep it filled. Rob

Taught him almost everything I know. Almost that is. If'n you see him eatin boogers, I didn't teach him that. Musta been the gorilla cause she can be a nasty thing sometimes. Rob

Well, this R795 ran out of fuel in the shop today again with a full 75 gallon tank. Been a real bitch to locate the problem but finally did. Here is the scenario that has happened several times: The engine idles fine for over an hour without presenting any problems, stumbles, or anything out of the ordinary. Also for the limited amount of driving I can do on my property, there have been no problems exhibited. Tonight I filled the cooling system with a 50/50 mix of green coolant, new coolant filter/conditioner and started the engine to let the coolant circulate. After about 1/2 hour of the engine running with no movement of the temperature gauge, I hold the idle at about 850 rpm for about three minutes. The temperature gauge rises to just over 160 degees indicated so I back the idle down to about 700 rpm. About 45 seconds later the engine starts to slow and characteristically starts missing on a couple cylinders, then starves out. As usual I pull the filters and the primary is plum full, the secondary is near empty. Same thing I've seen literally a dozen times. The discharge hose, (#8 size braided) from the secondary filter runs up to the top of the engine and connects to the fuel gallery within the injection pump. This hose slightly rubs on the intake manifold and barely had a pin sized hole rubbed through it. It was not enough to leak fuel to give itself away. I found it by taking the line loose to twist and allow evaluation on the underside; it was barely wet. I'll stop by the Parker Store for replacements on Monday. Be nice to put this one to bed finally. It was so strane the primary filter stays full, yet the secondary starves out. I can only imagine the secondary has a smaller capacity. These are all Mack filers, Red, Green, and Gray. Rob

Obtaining undersized bearings for a regrind is not that difficult I'll admit. What is difficult is obtaining bearings that are actually thicker in the back shells to fit the oversize bores after align honing the block. In the USA this is a bit difficult at best. I prolly wouldn't make any more power with that engine over the factory settings. The lower ends did not like to be "hopped up" much and asking for 1500ft. pounds from it is a bit much and durability will suffer; probably quickly. This is just my opinion. Rob

It all flows together with the therapy he is going through right now for the Peterbilt withdrawl symptoms. Rob

Always knew I was a saint. I don't do none of that. Some by choice; some by mandate. Rob

Taught right from the start. Rob

Naw, it is a by product of the cleansing action from the Peterbilt brainwashed mental capacities for many years. Hard to get over, but it can be done. I have faith. Rob

That's right. Nikki caught the new baby rolling over on her back for the first time with her camera. Once she gets the file transferred, I'll post it up. It's so cool to see them grow and change when you are not stressed for time, money, sleep, etc, Rob

That's kinda what I was thinking. Rob

Does that engine run? Looks like it hasn't had an alternator belt installed for quite some time. None of my V8 Mack engines have those style valve covers with the road draft tubes. I only knew of the aluminum type I have, and the stamped steel style without "Dynatard". Rob

HI Denny, I kinda look at it this way: We didn't invite those with differing opinions to the website but welcome them non the less, including their differing opinions. This is very much still in practice. However, these objectioners feel it is very much in their right to impact other's who do enjoy most everything about the site. Those who are unhappy are just as welcome to leave, or not participate further. No objections from me either way. Regardless, all are welcome, but the right to impact the majority will not be controlled by the minority. Not in my tenure however. I was confident results produced by the poll when first started were as they have shown. Rob

Hi Chris, I purchase most supplies from manufacturers who cater to the boat construction industry. I have found their products to be exceptional in quality and much better than what is available over the counter. Google "Ashland Chemical" as I've used them in the past, and they are helpful with their products. If you need to add more material to a build up that is already "waxed", just lightly sandblast the area as it works well. Only the gloss needs removed. The surface does not need dug into. Rob

Hi Grant, I would pull it out, and make damned certain the main bearing bores are good in the block. Most times when a main bearing spins in the bore it distorts the alignment. This can be repaired without the engine being torn completely down and apart but plenty of rags need to be shoved into the block to keep shavings contained. The other problem that you may experience with align boring that engine is getter oversized bore bearings. Standard ones are hard enough to come by unless specialty bearings are manufactured. This can get expensive. Keep me posted on your progress. You have too much time/money/effort involved with this engine to "wash it out" at this point. Need to work closely with a machine shop for cost evaluation for repairs before commiting to anything. Sorry to learn of the trouble. Rob

The stress strains my lazy eye. Rob

I lost boxes when the basement flooded nearly four feet deep several years ago. Those old cellulose photos didn't hold up well to getting wet. Rob

First topic I hit every visit also. Not because I'm any part of anything, but everybody picks on me so I have to brace myself each and every time I log on. Rob

I deleted the double post. Rob

Really don't think you will make anybody mad here. Especially with an honest opinion like "This guys a pussy". Rob

They don't bother me none. Of course I don't bother them either. We are all creatures of the earth and they are great at the shop property keeping mice in check. "Mouser 1" picks up the slack really well too. Rob

Think I sinned three times before my feet hit the floor this morning. Rob

Thanks for using the feedback forum. It helps other participants on the board. Rob

I'd still be one up on you. I bought another RL797 last week, (shhhhh). That makes two I've got to get after....... Looking at another also but it's an RS767 something with a blown engine. You got some catching up to do so best get with the program!! Glad you finally got one rounded up. Been a long search. Rob

Looks like the kind that will cost you for the rest of your life. Rob
