Originality / Re: Correct Oil fitting L35
« on: March 13, 2023, 05:28:05 PM »
Top picture is correct for 444052 elbow used on 67 68 69 2 bolt BB's. When the AIM RPO L35/U17 instructions where drawn they added the bushing 444026 / 444030 U17 which is not used on 2 bolt blocks but 444030 is used on 4 bolt blocks.
2 bolt BB blocks are drilled for 3/8" NPT and 444052 elbow screws directly into it with no adaptor ( bushing).
4 bolt BB blocks are drilled for 3/4" NPT and 444030 reducer bushing (3/4" to 1/2")  is needed but 444052 elbow is not used.

Looks like the pilot hole increases with the thickness of the metal.
Do all #8-32 hex screws have the same diameter at the base of the threads? If not then that could explain the different pilot hole sizes in the AIM.

Jim,
Thanks for the reply.
I wonder why the pilot hole of .125 is specified in AIM for a #8-18 when .136 is now specified?
Is AMK # B-12048 now the accepted replacement for 3858195 as AMK does not offer a direct part # replacement?

Can anyone with a 2nd version ( 67- 06,07 month) original L78 with gauges and grommet on firewall confirm what color oil lines they have? L35 would have the same oil lines.

No one with an original 67 06-07 BB w/gauges?

Jose,
Thanks for the pictures.
Copper line is not original, should be white or black 1/8" nylon with cone type ferrules and sleeve, but at this point I do not know which one is correct for early 67 L78 with firewall fitting. 
Mike S has an 325 HP 05B with firewall fitting and it has white lines and fittings which I believe to be correct for early version oil lines.
No correct information on early L78 version system just bits and pieces.
If your copper line has barrel ferrule and you use it with original gauge and adaptor you will have and oil leak.

Ed,
Should have remembered that about the 67 L78. Having a problem trying to understand what parts where used in the early and late 67 oil line L78's and L35's.
View C in 67 AIM A4 shows L35 but there is no bushing used on 2 bolt main blocks. A grommet is used at the firewall so this has to a late version of the oil lines.
1st version used clear oil lines. When did they start using black oil lines?
The grommet (2nd version) was added in 3-10-67 to 67 AIM but when did it go into production?
Jose,
A picture showing the fittings at the oil filter pad and gauge fitting would be great.

I believe the 1st Gen bushings are steel not brass.
