Paint on motor kount bolts

[Michael K.]

On a 58-62 should there be paint markings on the front mount bolts to show proper tourqing was done? Orange markings on the washers and bolts? If so anyone have pictures of original examples? Thanks, Mike

On my '62, the bolt end, washer,nut, and even the ground strap had a liberal application of red paint.

This is "Assembly 101" and I'm probably going to get a failing grade
but how do we get Chevy orange on the shaft end of the mounting bolt, washer, ground strap and nut long after the engine has been assembled and painted. Is there a second "painting" when the engine is assembled to the chassis?...maybe an inspecters certification of this assembly?...same orange?

Maybe a dumb question but we've struggled with this since we don't know the final assembly process that well.

Thanks for any insights.

Bill, must agree, have never seen any 'paint' on the bolts, they were installed on the engine/chassis line. Probably a previous owner touch-up?

Re: Paint on motor kount bolts

The paint marking that is being discussed is nothing more than an inspection mark. It was applied at the time the engine was mated to the chassis. In my case it was red, not orange.

Hi Ed, went out and looked at all my pictures of low mileage C1s and didn't find any paint that was visable. The mounting nut looks to have never been removed from the one in your picture. Assume this is a Bowtie car that is fully documented. Could also be that one in a thousand the inspectors hit/checked to see if things were being properly installed. Tell us more about the car.

Dan,

I had a Duntov 1962 and I can assure you that the judges look for the presence of inspection stripes on these washers, nuts and bolt ends.

Re: Paint on motor kount bolts

The only part of the '55-'62 engine mounting system that was installed at Flint V-8 was the large horizontal mount bracket sandwiched between the water pump and the block, and it's the only mounting part that's shown in the Flint V-8 Engineering Bill Of Material. That's the only engine mounting part that should have engine paint on it.

All the rest of the mounting hardware (vertical brackets, cushions, spacers, bolts, nuts, washers, and ground straps, with part numbers shown in the Assembly Manual) were installed at St. Louis, and should not show any engine paint.

Re: Paint on motor kount bolts

John, can't speak for 62's, never had one, but looked at many a 58 to 60's and never encountered any inspector paint on the bolts. Can't say if some had it, just never saw any still inplace on low mileage cars. One thing I've learned about Corvettes, 'never say never' but also they were all different too. Are the paint markings in the 61/62 JG? I'm always wary of seeing one car with a nice original feature and then saying all of them had that feature.

John and Dan:

I still have a copy of an email from the late Dale Pearman on this subject that states: "After the stover nuts were torqued to specs during engine assembly into the chassis, each were given a swipe of engine orange paint as an inspection mark. The amount varied but was always generous. The top of the WB-2C bolts, washers, ground strap, and stover nut were usually covered to various degree." This email pertained to my 1962.

Re: Paint on motor kount bolts

I discussed this with Dale back in 2002 or so (about 6-7 years after he wrote it, and a year before he died) when we were doing a Bloomington Gold Restoration Seminar together on C1 Chassis Assembly, and showed him the Flint V-8 Engineering Bill of Material, which he hadn't seen before.

In his unique way, he grumbled, nodded his head, and ordered another round of cold ones. Those who had the privilege of knowing Dale will remember that reaction as being as close as he ever got to agreeing to change his mind.
