General Questions

How can I be sure I am getting the right blower for my engine?
One easy way to check is to look at the engine’s serial number. The format would be something like 5043-5101, for example. The first number will correspond with the series. The sixth digit will correspond to the number of valves, with one representing two valves, and a two representing four valves. So in the example above 5 is the first digit, meaning it is a 53 series engine. The sixth digit is a 1, so it is a two valve engine.

Do you offer any kits for the Detroit Diesel blowers?
Yes! We offer a blower repair kit for many engines, as well as a gasket kit. Both come with all parts you will need for the task. If you are replacing the blower, it is essential that the gaskets are replaced, and our gasket kit will have everything you need for the job.

Are your blowers covered under warranty?
Yes, all of our new products have a one year warranty and all rebuilt products are thoroughly inspected, and carry a six month warranty. We also offer easy returns on unused merchandise, as long as it is returned to us within 30 days of purchase.

353, 453, 6V53, 8V53 Blowers | Frequently Asked Questions

Is there a recommended schedule of maintenance for the 53 series blower system?
It is recommended that the blower screen and gaskets are inspected every year, every 1000 hours, or every 30,000 miles, whichever comes first. If you see oil, especially on the blower’s lobes, then it is time to replace the gaskets. The blower should have a clean, metallic look, and be clear of oil residue. Remember when reinstalling that the screen side of the assembly faces the blower.

Why is the engine running slow, with black / grey smoke coming from exhaust?
This is probably related to improper air box pressure. This can be caused by a clogged inlet screen, by having a blower that is damaged or by a leak in the air box itself. If unsure, it is recommended that the pressure be checked by a manometer. These values range by engine, so if you plan on checking the pressure in this way, it is best to also purchase a manual to get the proper readings for your engine. Please note, this can also be a symptom of improper fuel, such as too low of a grade, or poor fuel distribution.

My engine is experiencing detonation (knocking), could this be related to the blower?
Yes. This is a complex problem, and can be caused by low coolant temperature, or bad fuel injectors. However, it could also be blower. To check, disconnect the air inlet housing and look for oil radiating away from the blower’s rotor. If there is oil, then the blower is probably picking up oil and pushing it though the air system. The blower should be taken apart, and all of the seals should be checked.

Can high lubricating oil consumption be tied to the blower? How would I check?
If you suspect an oil leak or other high oil use by the blower fist remove the air inlet housing and its piping. Run the engine at half throttle and at idle. Using a flashlight, located the end plates and look for excessive oil running out past the seals.

The blower seems good, but I don’t think the engine is running as well as it should?
If you have a blower that is in good condition, but you still suspect a problem, it could be the air cleaner. The air inlet restriction should not exceed 25 in. of water (or 20 in. of water for engines with a turbo.) If unsure, the air cleaner should be changed frequently, especially if the engine has to run in dusty or dirty conditions.

271, 371, 471, 671 Blowers | Frequently Asked Questions

I see oil coming out of the exhaust, is this related to the blower?
If you see oil being discharged through the exhaust, the seals around the blower should be checked. Bad seals can cause oil to leak and then be pulled into the blower. From there, the oil pushes thorough the combustion chamber and out into the exhaust.

I believe the supercharger is making an odd/loud noise, what could cause this?
Unfortunately, loud or odd noises coming from a blower is probably a sign of the bearings being broken, resulting in the rotors hitting each other. If this is the case, the blower itself would have to be replaced.

What would cause the engine to be ‘weak’, and not delivering its rated power?
Check the air intake system, especially the air cleaner and its ducts. Having a clogged air cleaner will make your engine gasp for air, resulting in poor, weak performance. It is a good idea to replace this piece often, especially if the air around it (such as a warehouse or worksite) is dusty or dirty.

Black smoke is coming from the engine, could this be related to the blower?
Though not directly attached to the blower, this could be related to the air intake system. Specifically, the silencer may be dirty, or may need to be replaced. If the engine has an attached intercooler, the fins may need to be cleaned. If the engine is overheating, this would be further indication that the intercooler is not functioning properly.

Why won't my blower pull in air, even though it is a new part?
If you have a new blower (or have one in good condition that is not moving) then it could be a problem with the blower shaft. The shaft itself could be damaged, or the blower shaft retainer, a small clip designed to hold the shaft in place, could be malfunctioning. The retainer is a small piece, and tends to lose tension overtime, so this piece should be replaced whenever possible.

6V71, 8V71, 12V71, 16V71 Blowers | Frequently Asked Questions

What if I hear a rattling coming from the blower?
Check the Blower Drive Shaft: This part should be inspected while you are servicing your engine.  It should offer some resistance when moved, and not move freely.  If you hear a rattling noise coming from the blower, or if the lobes are not moving as they should, you should consider replacing the drive shaft as well.

I opened my old blower and the lobes are dark and oily. What would cause this?
Inspect the Blower Seals: A supercharger should be relatively clean to function properly.  Brown or black coloration could indicate that oil is leaking due to a damaged seal.  

What should I do if the shaft for my blower isn’t staying in place?
Replace the Blower Shaft Retainer. This small, inexpensive piece can save you time later on. This retainer can warp and lose tension, and may snap if it is removed and replaced too often.

Can the blower lead to oil leaking into the gaskets?
Check the Air Box Breather Valve: Though not immediately connected to the blower, if the Air Box Breather Valve malfunctions, the engine’s performance can suffer.  In this case, the pressure in the crank case would continue to increase from the air being pushed in by the blower, which can lead to oil leaking into the gaskets.

What should I do if I found debris inside the blower while servicing?
Check the air cleaner or the inlet screen. The air cleaner is the most important of these two items, and should be replaced often. This inlet screen can be cleaned periodically, but if any part of the screen is broken, it should be replaced.  Damaged screens tend to let too many large particles into the engine.

6V92, 8V92, 12V92, 16V92 Blowers | Frequently Asked Questions

What should I do if I suspect the blower is not moving and my engine won’t start?
As a first step, inspect and consider replacing the Blower Drive Shaft, which is responsible for moving the blower’s lobes. If this piece malfunctions it can result in an engine that won’t start, or stall upon starting. If the lobes move easily, it is a good idea to replace this item as well, because the lobes should feel “stiff” when you try to move them.

I suspect my seals are bad around the blower, when should I replace them?
Oil should not be seen on the lobes of the blower. If you suspect that the interior has been exposed to oil, it would be a good idea to buy seals as well. This usually manifests in the form of brown or a dark red coloration to the interior of the lobes.

I have a new shaft for my blower, but I don’t think it’s moving correctly.
This blower shaft retainer is a small piece, but it can lead to big problems.  In order to work properly, the retainer has to have a certain amount of tension, which can decrease overtime. When it does break, it would cause the shaft to migrate out of place, leading to many other issues with the engine’s

I think the engine pressure is too high because oil is leaking. Is this the blower malfunctioning?
High engine pressure is partially related to the blower, in that the blower increases the pressure inside the engine. However, if the pressure is too high, which can cause oil leaks, it could be a problem with the air box breather. This piece helps to relieve pressure in the crank case, if it malfunctions the pressure will not be properly released, resulting in leaking oil.

6V92 and 8V92 Blower Specific Questions

I ’ve heard that the 6V92 and 8V92 have interchangeable parts, is this true?
These engines are similar in many ways, but there are a few differences that should be noted. The first difference is the mounting holes. These engines may have a different number of mounting holes in the top, even if the number of cylinders is the same. While most have six, some may have more. It is also important to note that many of the parts in these blowers are interchangeable, however, be cautious because the housing is not the same size for the different engines.

12V92 and 16V92 Blower Specific Questions

Which blowers fit the larger 12 and 16V92 Engines?
The parts for these massive engines borrow from the smaller engines. Specifically, 12V92 engines use two 6V blowers and 16V92 engines use two 8V blowers. It should also be noted that for both of these engines, if both blowers are taken out, then the rear blower should be installed first, before installing the front blower.
