    Hello everyone.

    I recently picked up this 1921 X5. The story goes that it was originally from Elkton, VA and has been apart since the 60’s with work being done here and there on it through several owners. Its mostly complete except for the correct driveshaft and generator, and a few other small pieces which will need to be found.

    Since the pic was taken, I’ve stripped it down almost to a bare frame. The engine will need babbitt, and some of the exhaust valve seats are cracked into the cylinder so I guess it’ll need to be sleeved too. The rest of the truck is not too bad.

    More pics to come later.

    I’d love to see more pictures.

    Post pictures as you go through the restoration process so we can all enjoy watching your project come together.

    It’s not too often we get to see details about a Pierce truck.

    I’ll definitely keep this thread updated with pics and lots of questions, too!

    I’ll start with a pic of the transmission. It was made by Covert, and I think the clutch was also. Not too much wrong here. The input bearings needed replacement, which the local bearing place had in stock. The top cover had rusted through in a few places, so I’ll need to weld it or make a new one.

    Removing the clutch. Everything looks to be in good shape. The gear shift box was full of water and the shifter rails were stuck, but they came loose fairly easily.

    I was hoping I could get away with a valve job and set of rings, but the further I dug into the engine the worse it got.

    Two of the exhaust valve seats are visibly cracked.

    Cracked into the cylinder.

    Dropped the rear axle out from the frame today. It was made by Stan-Par, and unbelievably heavy! Worm drive with a 8 1/3:1 ratio.

    Thanks for the pictures. :)

    That rear end assembly and spring packs are massive.

    Good luck dealing with the valve seat cracks.

    Bill,

    I’ve got an original X-5 parts catalog. Can you use it?

    Do not weld the block, stitch it.

    Ed is correct, trust me on that one!

    Bill, I sent you an email.

    The block definitely won’t be welded there! Still need to get it magnafluxed. There may be more surprises to be found.

    I finished stripping down the frame today. Its swinging from the crane waiting to be blasted. Does anyone know what color the truck frames were? I’ve found gray under parts, and I’ve also found black. It looks like the gray may be a primer coat, but I’m not sure.

    While blasting the frame, I found this. It looks all eight holes for the brake cross shaft were drilled slightly off, filled and then drilled again.

    The transmission got a good cleaning and new input shaft bearings.

    I mounted the transmission and air pump in the frame today. The air pump was one of the items that was removed from the truck many years ago and fixed up. One of the rod bearings was set up too tight, but otherwise it just needed cleaning and paint.

    I would have never guessed that Pierce would have just repaired the frame like that.

    I guess it held up fine all these years.

    Keep the pictures and updates coming.

    Its been a while since an update. I tore the front end all of the way down. The pins and bushings are all in great shape. The springs needed a lot of cleaning between the leaves, lots of rust, but they should be just fine. It is now painted and back on the chassis.

    Here is a pic of the bronze ring gear in the rear end. There is some pitting but overall, it is in OK shape.
