Hey all, newbie here, just picked a basket case, big basket too. Got a 69 FLH Kidney Shovel engine, an aftermarket rigid frame, no idea who built it, it's at least 20 years old from the title, it's not a weld on swing arm, and what appears to be a 64 pan trans. the trans numbers are 34703 64. My question is if any body can tell me about this trans, I'm thinking 3 speed. I can't seem to find it in my Donnys unofficial guide to HD. I've found just about every number but this one. The bike is a typical conflagration, old, not so old and not sure. Typical basket case. Seems to be a two to three inches over narrow glide with straight leg frame, and smaller fat bobs. Looked like a pretty fun project. Putting it together now to see what I got and what's missing. Looks like S&S jugs, super B carb and stock generator and distributor. Has a belt drive primary and a chain to the wheel with a rear disc that looks like it come from an FX model something. Sold my 67 pan shovel 18 years ago and bought a house for the little woman and the kids. Well the kids are grown and the little woman said sure why not. Got it in a garage sale, wont say how much but lets say it was almost free. Couldn't believe it myself til I seen my name on the title. My lucky day. Thanks all any help will be greatly appreciated.

 

If the transmission has a ratchet lid it is a 4 speed. If it is a jockey lid it could be a 4 speed or a 3 speed and reverse (rare). You would have to pull the lid to tell for sure. The reverse transmission will have an idler gear and a sliding gear.

If the transmission is a 62 or later model there will be a code number on the right front consisting of letters and numbers. These were anti-theft numbers and will only give you the year of the transmission. Here is the list.

cool thanks,

 

Well now is my dilemma, I don't have any numbers on any part of the case except those on the bottom. Interesting. I'm just trying to learn what I have to be sure I get correct parts. I'm going to guess the gaskets and seals for it will match with a 64 pan trans. Thanks again.

 

Photos will help but transmissions are basically the same from the late 30's to 64. In 65 they went to an electric start and the mainshaft was longer. A parts book will be your friend here. Harley part numbers consist in the format 12345-36 (They had an older 4 digit number also). The last two numbers are the model year when the part was first used. If your transmission has 4 studs on the left side it is a 65 and later transmission case. Casting numbers are not part numbers and aren't assigned part numbers until they are machined.

 

treeratt59, welcome to the forum. For 1964 model Panheads H-D used two trans cases: some had casting number 121 35 and some had casting number 34703 64 as yours does. The 34703 64 case was a transition item in readiness for further changes that were introduced for 1965 models. Some 34703 64 cases have casting date codes underneath but some do not.


In June on the H-G forum I posted info about some BT trans cases and I placed a link below. At post #11 there I begin mentioning some differences between 121 35 cases and 34703 64 cases. At post #14 I put pictures of a 34703 65 case. Post #15 shows where additional ID was stamped on the front of cases as of 1962 models.

OK I can see this is an old thread but this was the closest thing I could find for good info on the Ratchet top 4 speed identification after two hours of internet research, my search for an original Tombstone speedo prompted me to make sure my bike has the original trans, my numbers are as followed, 34703 65 on the belly, the front ID number is D 1276 It looks like by the numbers FlthyLucre posted that 65 66 and 67 could all have a D in the date code? Do the last four numbers have any significance as far as the date? I saw it is stated these were anti theft numbers so in theory wouldn't they have to match something else to be traced back to this bike or are they factory recorded numbers? Biggest question is this the original trans for my 67 FLB? The trans is still in the bike so this is the best detail I could get. Thanks
in advance!

 

As far as I know the numbers were only recorded at the factory for law enforcement inquiry. You may be able to get the factory to research your VIN and tell you what came with the bike.

 

seen the D before never gave it much thought but it might be a trans sold over the counter by a Harley dealer

 

Hi... I know this is an OLD thread, but I am old, with an old bike... I found the "anti theft' code on my 76 FLH and I swear it says S2163....

I noticed the letter "S" is NOT on your list but looks as though it COULD be an early 1976 trans???

I want to rebuild my trans, an there seems to be a 66 to E76 rebuild kit... and a L76 to E77 rebuild kit... I am not sure what the difference is...
but me being me.... I will guess and get the WRONG rebuild kit... *sigh*

What are you thoughts on my "S" Code?

Thanx
