Jordan,

That's a really nice solid trailer you have there; well done! Please keep us updated on the progress.

I havent had much progress to report on for the past while. However with the arrival of spring/summer weather the past few days I have made progress. Ive got nearly every piece that can come off the trailer off and sandblasted. I will be rebuilding the brakes over the next week. One set of shoes had the pads looking really good but the other set the pads were crumbling and falling apart.

It is supposed to be really nice out again tomorrow so I plan to start painting some POR on many of the parts once I get home from the OMVA show.

And all blasted and clean.

I took advantage of the great weather yesterday and somewhat today to paint the parts in POR15. After this I will start priming them and then painting them in the final colour of Khaki Green #3. I originaly was going to paint the trailer in SCC2 but I found KG#3 on most of the parts when I pulled them apart.

Ive also found some interesting differing features on these trailers from the information in the manuals.

In both SB-8 and SB-8A the body description has the fender brackets being riveted to the fender and bolted to the body. However in the Box Opening and Chassis/Body Assembling instruction it mentions using 26 3/8-24 x 3/4 hex head bolts to mount the fender brackets to the fenders and the body. The pictures in the manual show rivets whereas my trailer has bolts.

Another difference is a change of master cylinder. SB-8 in the parts listing has a part # of 91A-2140. This is a master cylinder with a 1-1/6" bore for a Ford 1/2 ton pickup. Whereas my trailer has the larger cylinder with a 1-1/4" bore for a Ford 1-2 ton truck. Looking over the picturs in the manual you can make out a difference in the reservoir height between the 1/2 ton and 1-2 ton master cylinder. So obviously both were used but only the small is listed.

Lastly a bit of a mystery item that doesn't show up in the parts listing or the wiring diagram. An extra side mounted tail/stop light. This was in the SB-8A manual only.

Took advantage of the warmish weather yesterday and got a bunch of parts painted in KG#3. Ive also got my brake shoes back from being relined and can now assemble them.

I have finally finished all of the body work repairs. I ended up cutting out the old brazed repairs and welding in new sheet metal. For the brazed over holes I found it easiest to simply use a punch and hammer and knock them out. Next will be getting the frame and body panels all sandblasted. One thing I noticed is that one of my side panels is a thinner gauge sheet then the other.

Dear all,

I'd like to ask you some info concerning the Brake master cylinder: is there a master cylinder interchangeable with the original one (F/91A-2140) that could be bought in the after market / internet?

If yes, could you please provide me the brand and / or the part number?

thanks a lot for the help and kindness.

Kindest Regards

Luigi

I believe that is the master cylinder still used today on some of the American designed 1.5 ton trailers.

They are available online under the part number you list: http://midfifty.com/item.php?INV_ID=9095

They are also listed at rock auto. Many different manufacturers for this cylinder, Raybestos MC1050 is one of the major manufacturers with a somewhat standard part number.
