Was this a crossmember? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

skokie · 01-09-2006, 12:42 AM

I was under the truck and I noticed what looks like the remnants of a crossmember. Heres a pic. Does anyone know what this is for?

Thanks

Wan't really across member, but tranny mounts... your truck used to have a manual shift in it, and that's where the mounts were. Had one on either side.

MDC · 01-09-2006, 12:49 AM

Yup. Crossmember for M/T. Someone cut it out and added auto.

kelsfine69 · 01-09-2006, 12:49 AM

If the truck has a 3 speed manual then it was cut out rather than drill the rivits and removed.

MDC · 01-09-2006, 12:51 AM

Sorry Longhorn, posted same time

skokie · 01-09-2006, 12:57 AM

Thanks for the info guys. Looks like I got soem rivets to pop out. Ill save em for a a stressed day when I need to take out some agression. LOL

Have fun - a tip from someone who recently had to do this on his ride -

When you have that chunk of xmember left, easiest thing to do is take a sawzall, sawzall the head off flush to the frame, then use a tool to pry up the remnant of metal (in taking off the head, the rivet will peel right up).

This beats the hell out of wasting a good drill bit or die grinding the crap outta the thing. If you can't get the head down close to the frame, consider grinding the remnants.

I did this - it's better/easier than using an air hammer. I tried drilling, grinding and chiselling for about 4 hours and got 3 rivets out... then got pissed, broke out the sawzall and in 15 minutes I had the other 5 rivets out.

I tried that and started my truck on fire (MANY years worth of the old six banger slingin oil on the mounts, frame and cab.) Fire was small and put out quickly, but man, did it happen fast! Be careful if you use torches.

skokie · 01-09-2006, 12:20 PM

How about a big hammer, chisel and a ton of agression

LOL

70short · 01-09-2006, 01:28 PM

I also used A 4" grinder to take the heads of the rivets down flush. Then used A pry bar. Went well.

Don't forget the earplugs

Seriously - nobody mentioned earplugs with the pneumatic hammers and whatnot. Very important stuff.

Putter · 01-09-2006, 04:22 PM

PLUS earplugs for the bystanders.
No need for them to hear all those cuss words!!!!

71chevytruckguy · 01-09-2006, 04:46 PM

i take a cut off wheel and cut grooves in the heads. then take an air hammer to what's left of the head. had to do that when i converted my truck from a straight 6 to a 350

hooked a log chain from the crossmemeber to the tractor and pulled. then welded it into place.
