Mike, I caught that too, because I have to rebush my shackles too Totally worn out bushings on the springs shackle.īy George Clipner-Los Angeles on Saturday, Aug01:50 am: Steve's bottom picture shows they were worried about the king pin and the tie-rod but did not care much about the spring shackles. It is much better to pack the bearing itself more often than to think any additional grease around it will ever get to it. The extra grease you put inside the hub will never reach the bearings. Keith is right about over greasing the wheel bearings. Why do people do all these silly modifications, when it could have been done correctly to begin with? If it were, there wouldn't be a problem.īy Richard Eagle Ida Fls on Thursday, Aug01:38 pm: I prefer grease over oil for front end lubrication. Not original but now I can grease the front and rear spring shackles on a regular basis. Next I drilled the shackle pins and added zerk fittings. Thanks for all the comments - looks like Zerks in the spindles but no change to the hubs other than a repack and new seals.ĭidn't feel like paying $300 for mae west shackles for my 15 so I bought the $30 spring shackles from Langs. KBīy Chris Bamford, Edmonton AB on Thursday, Aug11:55 am: If a bearing runs hot enough to melt out the grease, you have a problem that no amount of extra grease is going to solve. Most people over grease the front hubs, all that is needed is what you pack in the bearings.

I would suggest changing to zerk fittings then load a grease gun with heavy oil such as bar and chain oil or other heavy oil.īy keith g barrier on Thursday, Aug11:39 am: In the bottom photo, the bottom bushing for the king pin looks like it has been starved for grease for a long time, see how dry it is. Here's a modification I saw last weekend.īy Mark Gregush Portland Oregon on Thursday, Aug11:18 am: To save time from removing the hub cap to grease the front bearings, just add that fitting to the capīy Steve Jelf, Parkerfield KS on Thursday, Aug10:12 am: The fitting for the king pin needs to be located as shown, installing a fitting in the top of the king pin will not lubricate the bottom bushing.īy Dan Treace, North FL on Thursday, Aug09:23 am: With a modern lip seal and properly packed and adjusted bearing it should be good for a very long time. I see no reason for a fitting in the front hub. Oiling with chain saw oil from the top of the spindle bolt works too, but not a zerk in the top - the grease wouldn't reach the lower bushing (but oil does by gravity)Ī modern seal in the hub - as it looks like Dirk has - makes it unnecessary to add much grease, it won't go away? That zerk seems like overkill to me? (You can add grease by using the hub cap as a grease cap if you like)īy Donald Conklin on Thursday, Aug09:11 am: The zerk in the mid position between bushings would work fine, I think. They are clearly visible in the photos below, but blend in nicely when covered by little rubber condom-caps.Īnyway, these seem like a clever idea for a rough-service car like my speedster, and I plan to do the same.Īny thoughts, concerns or suggestions before I take the plunge? Thanks!īy Roger Karlsson, southern Sweden on Thursday, Aug09:01 am: I noticed that Dirk Regter's 1912 Around-the-World Touring has been modified with zerks in the front hubs and spindles (also spring shackles and tie rod ends, which are not on my list for tomorrow) to facilitate frequent and effective lubrication. This car sees rough and gravel roads quite often, and we are setting out on a 2,000 mile adventure into the Pacific Northwest next week.

I will be replacing the king pins and bushings tomorrow in my '24 Speedster. Grease fittings for king pins & front hubs?īy Chris Bamford, Edmonton AB on Thursday, Aug08:47 am: Model T Ford Forum: Grease fittings for king pins & front hubs? Grease fittings for king pins & front hubs?
