……..Deep now into the rear brakes on JayGee, my coach in preparation for the fall rally season
one point I brought up when thinking about brakes are these bearings in the hubs you pull off to GET to the brakes….they need love too.
Don’t EVER replace a bearing without also replacing the races. These look ffine…….see how shiney the back side of the 1 race? That’s because it was spinning! Zoom in on the face, the line at top and bottom is wear…feel the sharp edges… They wore sharp.
Guys…..tGuys…..these are MY bearings and seals! The bearings AND races may look ok to a line mechanic. Heavy weight and heat cycles is a way of life for our coaches.
Another subject is the inner seal on our rear bearings. The original seal had a little shorter shoulder. My guess….as parts get older with less demand, manufacturers “group” similar parts. For years, no one noticed this fact so the bean counter at the manufacturer did well. Recently this issue was discovered……well, it was always there. Pressing in in “flush to the hub” may cause the longer mount surface of the seal may interfere fit to the bearing. I install the seals just a bit proud of the hub…..check your bearing tolerance ad the seal goes in. Of course you could get that special seal grown 2 annual on a small tropics island…or you can use 8974S
I hand packed these….the new greasers work frankly awesome……my grandad sat me down and gave me SOP on hand packing wheel bearings. Hee told me “you havta feel the bearing all over” grind it into your palm spin it by hand and pack gear full into every crack….. THEN put in its race and pack that up while spinning it……..hey, it got embebed
All bearings now packed 2 seals in I got the greasy stuff done. Man, I get it on EVERYTHING……and I know I’ll never make a living at a line mechanic…. I can’t even thing with that goopenpucky on my hands… .and for gods sake, don’t wear a hat packing bearings……youve seen that nasty greasy mark on a mechanics ball cap!
All packed up, cleaned up and ready for the next step in my rear wheel brake/bearing project
Kinda Nice……..my seat…the perfect height…..tjough it’s now pretty hard to get up but you need to have a low seat. That aluminum bell with holes is a Weld brand wheel that broke apart. Yep, a 2 piece aluminum rim welded together…….dont use these 16.5″ rims. Well, them being 16.5″ they DO make a nice light proper low seat…….broken in half! It also travels well on the drum bolt pattern…
…..next we prep the wheel liner …..i mean everything’s out of the way. The end grain of your floor could be exposed to water in the wheel well. We spray a rubberized sealant spray all along the floor in the week well
Wurth – Highbuild undercoat. When we get back shipping get with us……in the meantime any rubberized flexible undercoat will work. Let that cute the day……..so tomorrow ill trim out the rest of the wheel well with satin trim black lawyer based spray to bite the plastic liner……..thats clean, right? You can coat the bogy and other stuff in there.
1973-74 models may have cracks at the top of the liners, GM found in the full low position that tires contact the liners. 1075 and one you’ll see a slight bump up in the liner to clear the 8.75×16.5″ tire. Bigger tires…..yep!
swing by tomorrow, I’ll finish prep of the wheel area getting ready for assembly. So see……theres a bunch to do BEFORE putting the brakes together!
see ya tomorrow
OOops….forgot to show you some stuff in this coach. I’ll do that too tomorrow. You KNOW only you guys who have stuck with me here on the restart of this page will be getting some of the behind the scenes stuff on some of our videos……hey thanks for sticking with me.
