Thread: bolts water pump pulley

Tweet

I put a 94 T-cover and water pump on my 84 block. I'm missing the bolts i purchased some 8x1.25 mm and 8x1.0 mm close but no fit i also tried some 5/16 sae and fine . Would they be a 7 mm ? I.m hoping i find the box been hidden in shed 10 years.


Ended up 5/16 24 , the one i tried must have been a metric that got mixed in my sae

good cause 5/16-24 is what i've always seen on american cars

Yep, I think you are right, SAE is what it should be. I just ran into this on the tranny mount for the T. The bolts were metric, so I picked up some 10mm bolts, but they wouldn't go in. I found out there are different thread counts, 100. 125. and 150...........i needed the 150's.

I'm so glad we didn't convert completely to the metric system.........it's tough enough as it is.

Don

i dunno i prefer it one way or the other sometimes..... its a pain when you're working on a car in the shop and half of everything is SAE and the other half is metric..... they've changed that a lot since the 80s to early 90s, now its all metric, at least its a little less confusing that way

I wish we had changed over. Metric is easy, everything is a multiple of 10. We should have made ours 10 inches in a foot and 10 feet in a yard

Thanks guys the 5/16 i thought i was trying was a metric . I took one from the A which has alot of 5/16 24 and it worked . This also helped identify those for the future .

This was a challenge though and the mix in bolts could cause a problem to some me in question thinking it was all metric myself . I bagged the old bolts but didnt find the right box in the shed .

At work on Danly presses they use a odd 1 1/4 x 8 threads per inch instead of the standard 7 per inch .
