Andrews J cam ID?
Found a cam that is advertised as a Andrews J cam for a panhead.
The only number that is on it is:
70503
Does anybody know if that is correct?

Re: Andrews J cam ID?
George,every one of those I have ever seen has been marked"Andrews" and "J" on the front lobe or front of the cam.

Re: Andrews J cam ID?
Thanks,
This is what I'm looking at, but I think that it may be for a shovel.

Re: Andrews J cam ID?
AFAIK, Andrews never made panhead cams, the timing figures and recommendations are for shovel motors. Will it work the same way in a pan? I doubt it, but it can't be too far off. The intake closing point vs. static CR should be a good match.
The only physical difference is that all 1948-57 cams use the bronze bushing and the 1958-83 pan and shovel cams use the Torrington, and the case-side journal is +.002" (?) larger.
All Andrews cams regardless of engine type begin with "2". All 1936-83 pre-Evo single cam (big twin OHV) begin with "212". "214" is older 4 cam motors. "288" is TC.
There is no Andrews product at all beginning with "7".
The box?
IMHO when the Andrews cam was bought, the old (H) cam was put in the box, and the box on the shelf. Maybe the seller knows, maybe not.
The number? May just be a machinist's stamp.

Re: Andrews J cam ID?
I have a question about the bronze bushing (48-57), I have looked at all the parts manuals that I have and can't find a part number for the bushing.....Do you know what that part number for the bushing is?kitabel wrote:AFAIK, Andrews never made panhead cams, the timing figures and recommendations are for shovel motors.

I got a tip that the Torrington bearing was not such a good idea from the beginning.
Any comments?
Thanks..

Re: Andrews J cam ID?
Done a bit more searching...and came up with these numbers.
25597-36 Engine case side
25581-36 Cam cover side.
thanks.......Let me know if I am wrong.

Re: Andrews J cam ID?
The 1958 Torrington is excellent, it's the later replacement with the internal cage that doesn't hold up.

Re: Andrews J cam ID?
The later "INA" bearings were the disaster, as they had a reduced bearing surface area that damaged the journal.kitabel wrote:The 1958 Torrington is excellent, it's the later replacement with the internal cage that doesn't hold up.
My modern associate tells me that ironically, the MOCO diagnosed the problem, but then went back to them again!

Re: Andrews J cam ID?
Yes, I think they went back to the INA sometime in 1992. They make an extra dollar or two per bike times the # of bikes
built per year, easy money, will last long enough to get through warranty period.

Re: Andrews J cam ID?
The Torrington is also referred to as a "full complement" or "crowded roller" bearing. There are no separating components, the adjacent rollers spin past each other in opposite directions as the journal turns. The advantage is higher bearing area since no space is wasted. The disadvantage of internal friction does limit the maximum speed (although this type has been used in crankpins), but it's still safe at half-speed in this application, and the same type was used as the inner cam bearing in the 1958-* Sportster.

Re: Andrews J cam ID?
I went to the ol-bushing type when I built my 58flh< they are a grenade that just needs time for the pin to be pulled!--Never had a problem with the bronze! I have logged many,many miles with this set-up!--To me the torington just adds a headache later on!---Richie
