OK guys. I have a homemade round tube tandem axle trailer.1" shaft spindles(axles).Common bearings L44643,races L44610,seals 471750. I put the bearing protectors on 3 years ago.Upon getting back from seeing Donald,ReidP,Matt,and the gang I noticed grease slung all over my new wheels and tires.Checking it out Sunday the grease just ran out when I took the protectors off on the left side.The right side was still to a peanut butter consistency.The inside bearings and races were pitted.I had pumped all 4 hubs full of grease before the trip Saturday morning. It's about 1 1/4 hr drive.Pics to follow.You'll see in the pics the hubs, then hubs on axle,with BRG in and nut. Just for pic purposes the race is not in,but you see there's only about 1/8" between hub casing and nut. So the questions in hand are,Upon pumping the grease in through the bearing protector do ya'll think it's enough pressure that it's going by the nut and bearing ,into the middle cavity of the hub ,then to the inside bearing? Or do you think it's just sitting in the bearing protector in front of the outer brg and not enough pressure to go by it?The other question, the set-up on an OE CC Trailer, is there a hole through the middle of the axle to the middle of the cavity of the hub and this is the way the inner brg. gets greased through these brg protectors?On my fix I was thinking about drilling a hole in the hub behind the wheel mounting flange,tapping it, and puttin a 90' grease fitting on it: or is this just overkill. I only trailer about 2 miles to our lake.Hope that wasn't to confusing.

Marty,
You didn't say if you installed new bearings when you put the bearing buddy's on. I'm trying to figure out if the rear bearings were pitted before or after the buddy's. New seals on the backside? Grease from the buddy's goes through the outer bearings and into the inner bearings. The spring loading of the buddy's maintain pressure when you cool the hubs/bearing down putting the trailer in the lake. If you overfill the buddy's the spring will bottom out when the grease expands and you will get grease out both the front and back of the hubs. They are sloppy anyway and the reason they do have the "bras" for the front side - I use them. Personally I like to see grease out the back side because then I know grease is getting to the inner bearings. Do you have any grease coming out the seal on the backside? Drilling the hole for a zurk in the middle of the hub is overkill and really you aren't gaining anything over the zurk in the buddy's. What grease are you using? What NLGI rating does it have? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I think the bearing buddy concept is ok but they are not really designed to fill the inner bearing, I think that would be a long shot at best. The real purpose as Pete stated is to keep positive pressure inside the hub assembly so when you drop a hot axle in the cold lake water can not enter because of that slight preesure exerted by the spring in the buddy. They are not designed for packing bearings only protecting them from water intrusion. ------------- You can’t change the wind but you can adjust your sails |

Yes I have the rubber boots(covers) for the buddies,never would see the grease come out the backside of the hub(seal) and yes replaced all brgs ,seals,and races,like 3 years ago. I use the Lucas Red"N"Tacky #2 Part # 10005. I is NLGI approved has a 540' Drop Point. This has an "anti-sieze" agent in it and is marine approved use. Could have been just a couple sets of bad brgs. Just the 2 on the left side had pitted and the races were scorched sort of. All 4 though were still packed tight with grease.But now everything new going back in and and I guess I'll check them at the beginning of every season,I guess.Just thought I could squirt the grease in the buddies and be done with it.Guess not. Thanks for the input guys,Pete,and Happy Trailering to all! ------------- 66 Skylark http://www.correctcraftfan.com/diaries/details.asp?ID=5041" rel="nofollow - 93 SN If you're not living in NC, you're just camping out! |

For once I disagree Pete, if grease come out you have a leak.And if you don't, you put that much pressure on the seals they will push out. I have had that happen on a car and it's done it on my trailer. On the car, I over packed the bearing and when the dust cap was installed it popped the seal. Every year except this one I have had bearing trouble on the GL trip. This year I put these on http://www.bearingbuddy.com/spindle_seal.html - Bearing buddy seals and didn't have trouble. The other down side to grease out the back, if you have brakes you won't anymore ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Gary, I use the same spindle seals on the trailer for my 81 and have had very good luck with them. Also agree, do not over pack, just amkes a mess. ------------- You can’t change the wind but you can adjust your sails |

Gary and Alan,
Yes, I agree that overpacking or overfilling will push lots of grease out the rear seal or pop the cap. However, if grease never comes out anyplace then you would have "greased for life" bearings and would never need to add grease. I'm not talking tons of grease out the back side - then you have overpacked/overfilled. A seal is lubricated with grease/oil as well as a bearing so you need to see some excess on the outside. With the buddys, at least they do have the relief hole in the face of the piston. Grease will come out there when they warm up and the reason for the "bras". Those buddy seals are nice! I've always thought about getting a set but I just don't put that many miles on my trailers so it's on the bottom of my list! ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Those seal are nice Pete,and they cured my problem ,but they take up room. When its all put together the axle nut does not seat far enough down to put in the cotter pin. I had to take the dremel and deepen the slots on the castellated axle nut. I don't like my fix and am thinking new hubs anyway,and when I do, I will put it all together to check it and if the new hubs are the same see about having the bearing seats in the hub machined deeper. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |
