I rebuild my 871 Detroit Diesel Blower!

This is the blower out of my 1967 GMC PD4107 bus. This bus was converted to a RV 30 years ago then left sitting for 23 yrs after the owner moved south. Its powered my a 8V-71 Detroit diesel and a Spice 4 speed manual transmission. All attempts to get the motor turning over resulted in failure, after much investigation the supercharger was found to be the culprit. we removed it and this is the process of rebuilding it. Remember, I'm an amateur when it comes to this stuff and this video is meant to be entertainment not instruction.....

Keep up to great work on the videos

When you are driving in a bearing always drive on the outer ring so you don't damage the bearing.

I appreciate your sharing with us also the time it takes for your videos making progress sir a good job. Could I ask if not to personal since you bus was abandonment basically was the purchase price of your bus?

[@looksbrokengarage175]

David It was listed for 2000 (estimated scrap value) I negotiated with the owner, and after describing my intentions to restore the bus I ended up paying 500.00

Diesel Pro has a blower rebuild video if you want to double up on the procedure. When it comes to fixing shit I love KZbin.

Hey, Looking for a little advice. I'm taking the blower off of my 4106 that's setup like yours it. I'm about ready to unbolt it, but I don't understand how the drive shaft comes apart. The boot around it is loose. Do you just pull it straight out away from the back of the engine. What happens to the shaft and how do you get it lined up to go back in. Your help would be appreciated.

This is way above my pay grade. 🤣

[@theq4602]

Its the joker blower. It has red paint and big scars on its face. And it wants you to ask where it got them.

Norman speed with commentary and I would sub and watch every video.

Grease sealed bearing means no oil feed needed. Those bearings are not the good ones

[@kainariylius392]

Helpful hint, when using a socket as a drift, grab a small extension. Where did you get the rebuild got for this?

@@looksbrokengarage175 thanks. Now I just need a BBC manifold and make a carb base.

@@kainariylius392 Look up, Eastside Garage Llc on Facebook. They have everything you need to mate an 8V71 blower to your BBC.

Perfect video and detail is much appreciated. I suspect my blower on 1967 MCI 5A 8v71 needs help. Getting oil thru to exhaust Y connection and in other places. Now I have way better understanding of whats involved to do this...or...the questions to ask if I have it rebuilt. Feeling better to attack it myself.

It's a v blower

[@TheMatrixgod]

where did you get the directions from?

[@johnrussell6620]

Isn't this a 2-cycle diesel engine and doesn't this "BLOWER" actually scavenge the crank case (vacuum)? Thanks for the video. Sorry for the late reply.

[@yeboisiggy]

Hey man, i’m wondering if you could maybe draw up a diagram of the blower and the blower parts? or if you have one already? the reason i’m asking is that i got one from my grandpa/grandma(grandpa died), and i was messing with it last night, and i don’t really know what any of it is. i’m talking about like what everything’s called and what it looks like. it’s harder for me to find info on it.

[@rodneymiddleton9624]

You did an awesome job especially the first one you have done. Love the long videos and the detail. I have to do the one on our MC8 with a 8V71. Thanks!!

[@wazza33racer]

Brass hammer??? I mean shouldnt the driving punch / drift be brass instead?? LoLz Keep up the good work...........its good to see some of these old engines getting some love.

[@pmd7771969]

Wooden dowels would work better for the plug seals Bv

[@TheMatrixgod]

wow who would think tackling this job themselves,lol

[@LacroixCruiser]

Thank you for the very informative video. One tip to add for the seal wear ring installation, put the rotors in the freezer, and the ring in the oven. They will drop on with ease.

[@JamesPretty]

53 mins in, I’m gonna bet you never get it timed right and it won’t turn after you put it together. Secondly if you drained the fluid out of that rotor and you do get it working it will fail in a short amount of run time… let’s see if I’m right Presses play…

[@JamesPretty]

1m18s in. I’m impressed

[@JamesPretty]

Nice job

A year later still running
