Pulled 216, patched hole in firewall, installed Mercruiser 153 4 cylinder and lengthened everything that had been shortened due to 216's longer length. Milled the water flow exhaust off the siamesed intake and installed an early 60's 153ci ChevyII exhaust manifold. Fired engine and it is so smooth running it has a drone to it. Have no idea what cam a Mercruiser has but it does have a heavy iron flywheel now. The distributor is still the no vacuum advance tightly sealed boat unit which may have to be replaced with one with the vacuum advance. Can't test drive till figure out why it moves 6-8 feet and locks up the right rear wheel. Axles are out so it can't be anything in the differential. A test drive will show whether the boat distributor will work. Original post with pictures 12-04-2018.

It has mechanical brakes so moving the lever should move shoes completely away from drum but drum may be warped or out of round. Will switch other side drum/hub to right side and see what happens. Thanks for any ideas.

Which model is your truck? Model LO (early 1928) has 2-wheel brakes and Model LP (late 1928) has 4-wheel brakes...both are 1-ton rated. I couldn't find your pictures...can you add a link? If the truck only rolls 6' with both axles out you may just be piling up a bunch of loose rust/dirt between the drum and shoes...I'd keep rocking it back and forth and see if it starts moving further each time.

It has 4 wheel brakes and we pulled all drums and hubs and cleaned to bare grey metal. Cleaned, checked for pits, spun, and re-packed wheel bearings. Brake shoes were new so may have to re-arch for drum fit. When it locks up the wheels on my tow truck spin but it doesn't budge. With something this radical one should be able to isolate the problem.

Since anybody who uses a brake lining grinder these days is likely to get 30 days in the electric chair, that's a pretty good work-around!

| | | | | Joined: May 2009 Posts: 135 'Bolter | | 'Bolter Joined: May 2009 Posts: 135 | Your truck is not a 1928. 1928 Chevy trucks had wood spoke wheels and no duals on the rear. The radiator shell is from a '29 or '30 car. Trucks had painted shells. It must be a '29-'32, which would have had a 194 c.i.d. inline 6 cylinder engine when new. If you have the hood side panels, they would help to visually identify your truck. If it has a factory I.D. tag, it will tell what you have. Chevrolet did not use a full floating rear axle on 1-1/2 ton trucks until 1936, so the rear end is 1936 or later. Only the early 1936 trucks had mechanical brakes. The change to hydraulic brakes came fairly early in the model year.
You can go to Google image and enter 1929 Chevy truck, then 1930 Chevy truck, etc until you find pics that match your rig. Good Luck.

Wish you could pack up your tools and jump in to help on this project. Another has told me the cab is a Dodge so from now on I better call it a Franken Truck. The history on it is it was bought and taken to a gold mining operation and never registered for highway use. I definitely had a 4 cylinder because there is no room for an inline six engine. When we got it there was a 216 Chevy that stuck through a hole in the firewall back into the cab. The driver was tough because the foot feed was up against the side of the exhaust manifold. The dump lever rods, pto shaft, and torquetube/driveshaft had all been shortened to accommodate the six cylinder. Has a 153ci four cylinder (Chevy II, Mercury Marine) engine in it now that fits both the firewall and the fan to radiator very well.
