Have been lurking on the gmcl web site - all the information about the ‘Classic’ and how to do it! Thank you members that I have contacted for information and parts. Now I finally can get my hands dirty.
We adopted a 1976 23’ Birchaven TZE336V100703, 455 the end of Sep from Winlock, WA. The PO got a 26’ to handle the grand kids and did not need this one. Drove it down I-5 to it’s new home in Lake Oswego, OR (just south of Portland).It handled so much better than those other rigs I had test driven. It has almost 54K miles but needed some work: aluminum rims, 16” Michelin tires, tire pressure and temperature sensors, KYB front shocks, replaced front end bearings when alignment was done and just passed Oregon DEQ test. The rig’s photo is under vpearce on gmcl. More photos will follow. Still some issues with the 4K Onan. Also have access to another 455 engine - getting it will take some time. Also have 9 - 16.5 steel rims and 6 GMC hubcaps - don’t fit the new rims - damn!
I finished the concrete pad, and now have time to ‘devote’ to safety issues and cosmetic upgrades. Thanks to Applied (Nick) and Jim Pounds, i’ve gotten parts and now comes the work. Presently I have a 2.25 T floor jack - will that handle the ‘Aluminum Falcon’ when lifting it on 6T jack stands and doing the following projects -
brake system flush (item from J Hupy to facilitate) and master cylinder replacement,
rear brakes (keeping drums) with stainless steel hose replacement,
emergency brake replacement (from Albert B) -,
quad bag installation,
new KYB rear shocks,
foam fire extinguisher from J Pounds - the fireman! for engine compartment,
Ramco power mirrors
maybe renovation of fuel line just getting to that ethanol issue,
maybe rear bearings,
While the bogies are apart, will pack the rear bearings - any recommendation on check bearing condition - and also any other method of packing the bearings, like the extended zerk fittings or something else?
Also will be replacing the shag, gold carpet and cockpit rug with something easier to keep the pine needles from sticking into feet here in the NW. Recommendation are appreciated - cockpit covering with 3/4” horse stall matting, and vinyl on the floor - noticed that on the site.
Is long, but I will have time as well as some trips this year - have to get busy.
Thank you for your comments ahead of time - what an amazing source of information from all of you to pass on to newbies!

Welcome, Virgil.
>cockpit covering with 3/4" horse stall matting
Love the stuff, but it's too heavy. And it doesn't fold very well, having all the flexibility of a sack of concrete. You're going to be in that engine cover a lot, even if it's just checking the tranny fluid.

I personally feel that 2.5 ton jack is just not quite enough. Technically I think it will work, but it is at it's max. 2.5 ton = 5000 pounds. Total weight of a GMC could be 12,000 pounds, so you will normally be lifting up to 4000 pounds at a time, and the 1000 pound difference, I would personally like a little more safety measure in going at least to a 3 ton jack.
quite a few people like to have an extended 3 ton jack, they are harder to find, but reach under the front of the coach much easier.

Virgil, when jacking up the front of your 23 footer make sure you jack it in the center of the front crossmember. If you try to jack one side up at a time you will most likely crack the front window on that particular side. Ask me how I know :)
Thanks,

I have to use my 3.5 ton floor jack to lift either one of the bogies or the center crossmember in the front. The smaller 1.5 ton aluminum one will just barely lift one wheel at a time (in the front). I bought a fair size 3 or 3.5 ton aluminum and steel floor jack from Northern to keep in the GMC at all times, but when I lift the bogie or the center front, the side rails bow! So even though it was a good price and lighter than the Michelin 3.5 I got from Sams club years ago, it's not really up to the task. Keep the jackstands at the ready when lifting one of these coaches(or anything for that matter)and get them under there as soon as there is room as Mark mentioned.

Virgil, I use a 6 ton for single lifting of the front end, and 6 ton jack
stands (2 of them) on the frame where the front clip bolts on. I have a 2
1/2 ton OLD CRAFTSMAN floor jack that I use under the bogies.

Use at least a 3 ton jack. Be ready with cribbing or something else to slide under the frame when you have the coach on the jack. Jacks can and will fail. I had one aluminum one blow up, total metal failure, with a GMC in the air momentarily. Gravity works. I generally will slide the wheel under the frame, if I have removed one.
If you are jacking up the front end, center the jack on the cross member. Lifting just one side may result in a cracked windshield (about $800). Lift the rears at the boggies. If you look under the frame you will see some doubling at cross members. This is another good jack spot. The frame will bend if you fail to use a reinforced location.
I also have a collection of 4 x 6 and 4 x 4 wooden blocks to slide under the coach.
Safety first.
And welcome to the GMC Clan (Cult). You are going to met some of the nicest people.

Vigil,
About your 4K Onan, they can be made to be fun and reliable. Start by downloading manual X7425 as that is the 73&4 but it covers the BF Onan and the others do not.
-If you are going to keep the rear drums (which work great when they are right), consider the the drum brake reaction arm kit from JimK. (aka floating back plate if you are an old dirt biker). The improvement is awesome (in the real meaning of the word).
-For old brake lines, look up and buy a full set (you will never regret) of ViseGrip LW - come in three sizes, but they can grab on a hex and do no damage or slip. It is possible to torque off an brake line nut without the tool slipping (a two beer story).
-Before you go to quad-bag, look up and evaluate the Sully Bag kit. Some of us like it a lot and it is less expensive.
-If you are going to have the tanks down, I will suggest that you go to metal (Polyarmor) over the tanks. If you do want to get the tanks down, I suggest you read this thread (#msg_174745). Read it all and you will by-pass a lot of grief. I now have no rubber fuel line that can't be changed out lying on the ground.
I have a 3-ton Hazard Fright jack that seems to do everything I need. It is a POS compared to my 50yo Hein-Werner, but that is only 3K# and can't do much for the coach. When working around a coach, remember that an airspring (bag) can blow at any time and there isn't enough room for a snake under the back when it does.
23s have a lot that is different than 26s, and being a Coachman it is even more different, but there are people here that know and will be ever so happy to make your jobs go better.

It seems everyone's about covered it but these are my observations. I have a pair of 2.5 ton aluminum and a 3 ton aluminum/steel jack I picked up at Costco. The little guys can do the job but the 3 ton does it with zero drama. For under $100 the 3 ton is the hot ticket for me. Of course I'm quick to get some safety stands/blocking under there before I ever get under there.... JMHO
