Anyone know how to remove the brake drum from the rear axle on a commercial 63?

Is it just pressed on? I dont want to smack it around alot if im missing something.

Just a cleaning and restore. Hopefully the rear suspension goes back together again without issue. But if i have to ill give it a completely different rear end. So far the parts I've needed have all been relatively generic. Nothing specific.

I've bypassed a couple of CC parts cars over the years for that very reason. I did allow myself to get hooked into pulling 4 Series 75 Sedans/Limos, and now have an entire row of doors for those limited production cars! LOL. I found the 1st one down in Tarpon Springs FL and thought I would use one as a daily driver, but it was a complete rust bucket … and by the time I pulled in my 2nd and 3rd and 4th in what seemed like rapid fire succession, I had come to the realization that I wanted one very good driver car (my 64 CDV) and the others would be parts cars.  So 3 driver cars were sold, and 'Dino' has been my pampered driver ever since. As far as parts, at least the 1959 to 1965 Series 75 shared the same bodies and parts such as fenders, hoods, windshields were moved pretty fast but again, still sitting on a wall of doors! LOL  I do think the CC are very cool, but sometime fate has a way dictating a person's direction in terms of cars and life in general.

Unless the CC is super cheap, I do not recommend parting out any. The cab, engine, front suspension are the same with a few exceptions in the cab. Everything else is different, and you will be sitting on most of the parts for the rest of your life.  I will try to find a buyer who needs a parts car, if I come across and more CC parts cars.

Thank you for the picture Russ.  That's what i was looking for.

Great comparison picture. I just saved as a reference as I don't know if I will ever get a CC body style in.

The right tool for the job is a must here. I had to pull the drums on my first hearse. I didn't have the tool, do I tried the brute way. I chipped a drum and stopped right then and there. Ordered the right tool for the job.  On a serious note, if your going to bitch about a 45.00 part, you should have bought a honda. These cars are expensive to own and maintain. parts, tools, gas, I could go on.  You may ne able to rent one from a local parts store, but owning is my preferred method. You will have the tool when you need it.

The picture shows the CC axle on the left, and the standard axle on the right. There is a keyway on the CC axle.

From reading the shop manual and looking at your pictures, it looks like your studs are pressed on to the hub/drum at the locations marked with yellow x's in pic below, and the hub and drum slides off the axle at green line in pic low.

To remove, a 5 jaw puller is attached to the 5 wheel mounting studs (circled in orange in 2nd picture) from the outside. The puller pushes in on the axle and the hub and drum slide off. I looked up five jaw hub puller and found the one in 3rd picture from the WalMart site (Click Here).  It looks like the tool Russ linked to is a 3 jaw puller which should still work, but pointed out the WalMart puller I found as there are 5 jaw pullers out there. The WalMart tool is $149 and can probably find for less if you look around.. or local auto parts store  may have one for rent or to loan.

Does anyone have a pic of the axle hub of a 63 commercial with the brake drum off?

That would clear things up fast.

I have no experience with the Commercial Chassis rear ends but unless I am looking at the picture wrong, it looks like the lug bolts are attached, or built into the the drum and not the axle shaft.  The shop manual for rear Axle Shaft Removal on page 7-9 note 7.a.3. states:

"3. Release parking brake and pull wheel hub and brake drum assembly off shaft.  Use a five-jaw puller to reduce the possibility of warping or distorting the brake drum".

I think Russ has worked with the commercial chassis rear ends and if he is sure the tool he noted will pull the hub&drum off the axle assembly that is one option. Personally, if this were going to be a one time repair, instead of buying another tool I would run it down to my local old school machine shop. I am sure they have different ways to press that hub& drum off.  Problem is not everyone has a get-er-done old school machine shop right down the road these days.

Just to show the difference, here is a regular (non-Commercial Chassis) axle shaft & bearing assembly where the wheel hub and mounting studs are an integral part of the axle assembly.  This is very different from the CC setup:

That only works if the lug bolts are attached to the brake drums. If the lug bolts are attached to the axle. Then the puller wont work. From the look of the axle inside the drum, the bolts have to be attached to the axle right??

I removed the front cover to change out the timing chain & gears all that went pretty well when I put the cover back on I put in a fresh oil filter ,filled it up figured it would be enough to prime the oil pump when I started the car .Fired up the car and heard lifters rattling, So I shut the car down right away. So I removed the oil filter housing, and poured oil down the neck of the oil pump housing filled it up and filled up the filter put it all together and fired it up and same…

Caddy members, I’m upgrading my 64 2-door coupe deville.

motor guy lost my block (machine shop went under) so I’m replacing motor & tranny with LS conversion. I have motor parts (other than block) for 429, rebuilt transmission, converter, and too many other motor parts not needed with fully dressed LS going in.

Email me (Tom.reichenberger@ipsper.com) or call me (210-739-4854) if you’re interested…..I live in San Antonio, TX.

thanks, TX…

Trunk Open and Lock Mechanism is in Closed Position

Posted by Chris Anderson on September 13, 2022 at 7:14pm 7 Comments

While working on my trunk lock on 64 Cadillac, I mistakenly closed the locking mechanism while the trunk was open.  Is there an easy way to manually release the lock back to the open position?

Thanks.

Fuel Pump Failure

Posted by Jon Shields on August 6, 2022 at 6:48am 4 Comments

Hello,

I'm located in Melbourne, Australia and my 64 sedan de ville is stuck in the garage due to failed mechanical fuel pump. The first after market mechanical fuel pump lasted a few years before it failed & left me stranded 5 hours from home. A hire car and tow got us home. On inspection, I noticed a valve not seated within the housing. I was optimistic, pressed it into place and assumed the pump was good to go. But alas, no. From what I can now determine, the diaphragm pushrod…
