Evaluating Sleeve and CrankShaft Wear

Tue Mar 13, 2007 11:45 am

I'm in the process of restoring a Super C that was my fathers. One of the Cylinders has a small pit in the sleeve about 3/16 in diameter, and one of the main journals has a small "blemish" on it that feels rough to the touch, and if you try really hard can kindof catch your fingernail on it. Other than this the sleeve measurements and journal measurements are still within the factory specification.

Is there a rule of thumb for determining when sleeves need replaced or journals machined when they are in spec but have issues like these?

I just joined the Forum today, but have been reading posts for sometime. Its amazing how addicting restoring these old tractors is. Its been a enjoyable experience and am looking forward to getting the old girl running again!

Thanks for any information you can give me.

Mark as for the crank If it ain't fixed you will be back in. As for the sleeve it is according. There may be enough left to have it bored and then again there may not be enough. Rather than the size of the pit the depth and how much the cyl is worn is what makes the decision.

First, Image to the greatest forum on the internet, and to the Cub Family. You will find that all the folks on this forum are kind, helpful and just full of Cub info and knowledge. They also happen to be the finest folks I have ever met :!: :D

I wish I was able to offer more than just moral support, but the only experience I have with the "C" member of the Letter Series, is watching how my brother-in-law managed to split one in half without even trying..

Hopefully we will have some technical resources on the Manual Server for the "C's" sooner than later. :wink: :) Some of the info below is applicable to your C.. especially Binders, the General Troubleshooting tips, some of the Sponsor links etc...... but we will all try to help as much as possible.

Ok, so here is the spiel Image:

I would suggest that you read this thread: New Members and Visitors, Please READ Prior to Posting. There are many great links to informative pages such as the ATIS FAQ's 1 and ATIS FAQ's 2, The Best of H.L. Chauvin who has written very interesting articles on troubleshooting common problems with your Cub. One of the other projects we have been working on and it will be a continuing effort is the How To Article Archive. This the the place to go to get all the quick links to some very good articles written by many members of the forum on solving some of the problems we encounter as we repair, maintain and up-grade our Cubs. Keep looking for this to grow.

Also, you might want to visit the Cub Manual Server as there is tons of info on servicing, maintaining and re-building your Cub. In addition to this basic information, there are also a number of other useful tools available on the server. There is the Specialty Services page which has contact info for neat stuff like getting your seats recovered, buying quality Decals, Serial Number tags and a host of other neat items. Also there are the Parts Pages - both Used Parts Suppliers and New Parts Suppliers pages with links to quality dealers. I am always looking for YOUR favourite dealers for New and Used Parts to include here. These pages are intended to complement our Official FarmallCub.com Website Sponsors:

I would also recommend that you visit Binder Books and purchase the three most important manuals you can own for Maintenance, Repair and Rebuilding your Cub. These are the Owner's Manual, the GSS-1411 Service Manual and the TC-37F Parts Manual. Although they are available on the Cub Manual Server, it is better is you also have your own paper copy. Binder Books is the only Authorized IH Publication Reprint House and they have the best quality manuals available. Most other's are not of the same quality. Just a personal thought here, the I&T Shop Manuals, although helpful in some areas, really are not sufficient for the job. If you wish though, they are good additional reference works.

IF you really want to get the skinny on all things Cub, might I suggest you get a copy of Ken Updike's Farmall Cub and Cub Cadet's :?: . While you are at it Original Farmall Cub and Cub Cadet is Ken's latest addition to the series. Along with Guy Fay's Letter Series Originality Guide, these are three must have's in anyone's collection.

In addition to the above information, don't forget to check out the various articles that are available to help with your Repair, Restore, Rebuild or just your Maintenance Projects. There are a number of sub pages such as Electrolysis or Rust Zapper's, Maintenance Tips, Jigs and Techniques, Implement and Part Sketches and of course the Paint, Decals & Other Finish Questions which has the Paint Chart and the Paint Committee Decisions links.

Oh, and while the program still lasts.. you might want to check the Announcement: Navistar Free Gas Cap Offer - On-Line Form thread at the top of the Cub Forum and send away for the new style safety cap before that program runs out as well.

I truly hope that you enjoy your Cub and that you will be a frequent contributor to the forum. Again, Image to the Cub FamilyImage :D

Small blemish first. Sometimes you can use a slip stone or rouge stone to polish up small blemishes in the crank.

Sleeve. I would make a couple of passes with a hone. Then check (mic)the pit. Perhaps the pit can be hone out and the sleeve still be in spec (usable).

Sleeve. An other alternative is to replace the sleeve and piston as a set. Sometimes this is the best solution.

Thanks for your help. I'm dropping the block and crank off at a machinest this morning. I'll have the block hot tanked and let them look at the sleeves and crank. Most likely I'll need to resleeve and have the crank ground.

Thanks for your help!!
