Air Cleaner Repair M1008

[Abbylind]

The wing nuts to the air cleaner (M1008 ) had stripped out at the upper air cleaner cover level. They would also spin around as the engine idled. I took a couple of rubber o ring washers and placed them under the wing nuts. This gave them new threads to bite and the rubber keeps them from backing out.

PS: I checked the all-thread studs and made sure they were secure in the intake first.

there is supposed to be rubber attached to the base of the wing nuts to do exactly the same thing. The nuts will walk off the studs if not there.

After 26 years mine must have taken a hike!

I think they dry out and fall off. I just made a few from a roll of rubber gasket material and spray adhesive.

Thanks, never would have thought about the nuts and no rubber!

Interesting... on my M1009 one is a standard wing nut and washer, and the other is a one-piece wing nut with a washer-like base that has a nub on the bottom to mate with grooves in the air cleaner cover. This, I presume, keeps it from vibrating loose.

Which one is original? I'd have to say the one-piece unit. This is what I recall from other older trucks I've seen. Maybe there was a difference depending on the year? Mine is an '84.

( The shiny spot at the top is the nub, which is a bit worn down )

Mine looks like your first pic. ( 86 M1008 ) No nub on the bottom though. IIRC I had a 93 Blazer (full size) It had the nubs on the wing nut.

A word of caution. I take a nut and put it on top of the wing and jam it against the wing nut. I had a 6.2 where the air cleaner stud broke loose at the base and wobbled around , worked loose from the nut and got sucked into the engine. it was not a good day and cost me a prefectly good engine. It was completely destroyed.

Just to ask . Is there a sock or foam cover over air filter(paper one) I thought i saw it one time in TM?

Mine came with some sort of foam cover over the air filter element.

I use nuts with lock washers forget those wing nuts!

Thanks cpf240, I'm looking for one, if you hear of something? Parts House thinks I'm crazy sometimes but I can't find a listing yet.

When i bought my truck it had the second filter screen over the element, I bought a new wix filter for the truck and there was none on it. However while at work i had to get a filter for a 92 chevy 3500 with a 6.2, bought a new wix and it had the second filter thing in the box with it...dont know it they are different part numbers or not....

My 1009 is the same way one side has washer, other side has the indent.

I'd say the nut/washer is a replacement after the factory nut bailed out.
