Help with the main shaft kicker side bearing HD 9020 roller bearing . Looking at reputable bearing brands they say the roller bearing has 2 metal ( i will call dust shields ) on both sides of bearing one would think it to be open on the inside of trans to get lubed from gear Oil. Also i cross refed the OME to 6305-2z-c3.

ordered Jims shifter align tool. and the spacing shims .007" & . 014". I cant find Hi gear end float spacer kit that eastern A-35131-set sells. i can only find eastern 5 packs of the same size shims that is OK if your doing heaps of Trans jobs plus i dont know what size i need. trying to have every thing at home for when i get better health wise to start the work and not wait for some shim (spacer ) to come from the US. if any one can tell me where the A-35131-set is for purchase i would be grateful. Also 88 usa made stock size needle rollers. i can get and have sonax over size ( the ones i have are .0004 and .0008 and think larger available in OZ. i did find a Ebay site that claims to have 4 packs of 88 HD 9084 Stock size sold in a zip bag but the could be Taiwan made and cost for 88 is $80 abouts.
Thanks in Advance

Good luck. I used the SKF (Italian-made) 6305-ZZ here and that seems pretty decent compared to the Chinese ones. It's shielded on both sides. Timken has a 6305-ZZ also (shielded on both sides). The original ones that I've taken out were only shielded on one side, installed with shield facing the kicker cover, as you surmised. I've replaced these in three different transmission rebuilds and I haven't yet found an exact match for what I removed. I went with the best I could get.

I Googled this once upon a time. There is a difference between "sealed" and 'shielded". Sealed is just what it says with a rubber seal to keep lube in, and dirt out. On the other hand, "shielded" is a metal shield to only protect against debris, and I assume lets oil pass into the bearing's innards.
BTW, # 920 is a Ball Bearing. I had to look it up because "roller bearing" threw me off.

I could not find this part number, 35131-, in my 1958-68 H-D parts manual. I found # 35130-36, Retaining Washer, which I believe is reusable. Do correct me if I'm wrong....

I found 35131-36 on page 85 of my 58-68 parts manual - and it is the main drive gear roller retaining washer - and it is reusable, as long as it's not trashed and your MDG end play is in spec.

Wow, Jim, we must have different PMs, page 85 in mine is gas tanks....
And in the back of the book is an index of PNs, that # 35131-36, is not even shown.
Now, on pages 42 &43 the washer shown is # 35130-36, but in my 1941-78, the # 35131-36 does exist, 1941 to E 77 apps.
WTF? So even the factory publications are not to be trusted....
So I went to the ultimate authority, Tedd's V-Twin, H-D # 35131-36, = VT No 17-0162, is in stock, .060", in a 5 pack.
They also list six more over sizes....
....In the land of bewilderment.... RooDog...

The number in question is 35131-36, not 65131-36. Anyway, I misspoke about my parts manual. I have the 58-68 in a real physical paper version, but I was looking at a pdf download of 1941-1984 FL Model (Harley Davidson Part no. 99456-84B), where I found 35131-36 on page 85. It's depicted in the countershaft illustration and parts list, which is interesting since it's on the mainshaft. And none of this has anything to do with the mainshaft ball bearing anymore!

My printed 1941-78 PM is H-D # 99456-78 (I double checked that number). Not enough beers this week so my sixes look like threes. I corrected the numbers in my post, thanks for straightening that out for me, but a PM would have done just as well.... LOL..

The Ome is no. 39 and is 35130-36 and is .060. The eastern | A-35131-set | as printed in there catalogue has 5 sizes starting at .060" then up sizes in .005'' for Main drive Gear end float adjustment this is what i need.
Also i found OME bearing 9020 to Be as Mongrel said 6305-z The Z is the metal shield ZZ or 2Z is 2 shields and just Z is one side open. And is available for some good name brands. With SKF they can be made in Italy or some less desirable places so it must have made in Italy printed to box & on Bearing. so i only need that A-35131-set. eastern Cat says made in Usa. As i said above all i can see on google here is 5 packs off the same size Spacer starting at .040 to.080. So need help only with finding eastern part no. A-35131-set.
Found em on flea-bay but comes up out of stock once in there sites. Also Eastern does not sell to AU you need to be a dealer from memory some one must have the kit. Sorry i cant send Pics as for some reason my phone will open site but not let me in? computer only works. :oops:
Roo my BAD on the naming of 9070 its a BALL bearing. :idea:

Bump. done some research on the HD 9020 and double metal shielded bearings for Trannys. They are Pre packed but do let oil in and as a manual trans has no filters the metal shield protects the bearing from metal chips etc ( later Trucks or tractors in US have a pump cooler & filter ) So when Able will go on the hunt for a good quaity 6305 ZZ ! Also 2Z means the same. Double shield. This is strange that the bearing is measured in metric 25mm ID X 62mm OD X 17mm wide. Where did the come up with this in 1936 ?

The metric specs threw me when I first started searching for a high quality version of this bearing. Most of the world has been using the metric system for hundreds of years. And H-D has always used readily available parts for bearings, electrical components, etc., rather than manufacturing these parts themselves. The dimensions of this bearing probably were suitable to provide the relatively light press fit on the main shaft, or some other suitable feature, so they incorporated it into the transmission design. Or I may be completely wrong.

I use SKF sealed and pop out the inside seal.I’ve found McMaster Carr to be the most reasonably priced bearing supplier. Many products do not spell out the brand, most times you can open a drawing that tells you the brand while viewing a specific part.

Sealed, and shielded bearings are not the same thing.
