1972 301R rockshaft cover removal problem

Bw-n-alvin · Jun 10, 2021

There is a spring connecting the rockshaft cover to something below that is keeping the cover from being removed completely. Danged if I can figure out how to detach the spring so the cover will be free to remove. Any ideas?

To be clear you have a 301. From the parts catalog the R means DIESEL, COLLAR SHIFT, WITHOUT LOADER. Is that correct for your tractor? Do you have the technical manual, TM1034? If not you should get one, and an Operator's Manual as well.

I don't have a 301 manual but I think the removal is similar to the 2030. Do you have the load selector lever in the "L" position? It has been several years since I had a cover off, but I don't remember having to remove any spring connected between the cover and transmission internals to get the cover off. I think you may be hanging on the cam follower lever because the load selector lever is not positioned properly.

I may be wrong and one of the other guys will be along to correct me. In the meantime make sure the load selector lever is in the "L" position.

Normally I would agree that correct tractor identification was very important.
When it comes to L/D mechanism on JD utility tractors built from '66-'92 they're all very similar.

I was taught when repairing L/D mechanisms on these tractors to place L/D control lever in "D" or "min" whichever designation applies to tractor model being repaired.

I think the cam follower that is the part ""shaded in photo below"" is somehow hanging in rockshaft control linkage. There is no factory spring attached between rockshaft housing & trans case. Spring(key 8) is attached to RS housing & 3pt control linkage that's also also attached to RS housing

Thanks for the feedback. I won't disagree on not needing the ID I included here and many in those years being the same. I am a bit leery of letters on the end of model numbers from issues, often around crawlers, where using a suffix incorrectly leads to people chasing answers for the wrong machine. Many, with a straight 450 crawler for example, have said they have a 450C meaning crawler to them. When in fact there are many differences in a 450 and a 450C, answers for one can be totally wrong for the other.

I suggested the L/D lever be in "L" as that is what my 2030 technical manual specifies. My thought was it is hanging on the cam follower lever, which doesn't come off with the cover and would have a spring connected to it, visible if the cover was lifted a bit. I found a couple pictures that may help him with what is there.

Thanks & you're correct about setting lever in "L". I must have been thinking about when R&R load control shaft. Spring that I was referring to which is barely visible in lower photo is T22473 & spring in your upper photo is T21955
