[1941 Super Coupe Gearbox Question -Mystery Hole]

21 hours ago, DonMicheletti said:

The seal of that pin is no different than that of the cluster gear counter shaft. The tight fit can seal it.

But who uses a new pin as the manual says?   No one. The groves only extend part way on the pin at the outer end.

So re-using the old pin usually requires sealant.

I had an Oldsmobile with the same setup and it had no leaks.

 

When we rebuilt Neils trans, I didn't want to remove the reverse Idler just to avoid that possible leak.

That's what I think it is

Thanks to all of you . Looks like it's the pilot hole . I cleaned it out and upon inspection there's no thread. My gearbox sounds great in all fwd and reverse gears . I cleaned all the residue oils that where due to old leaking rocker cover gasket. I've seal the hole and good to go ..once again thanks to all ..appreciate it

Option codes for Buick 1941 are as follows, A-dual carb, B-accessory group, C-special steering wheel, D-rear wheel sh, H-J radio, K- heater, O- grained garnish molding, P limousine dictaphone, R-foamtex cushion, S-body hardware group, T-rear seat center arm rest, W-special gear ratio, X-high springs, and WWT-white wall tire. Option codes for Buick 1939 are as follows, A-panel board, B-special gear ratio, C-window reveals, D-accessory group, E-special wheel, F-oil bath air cleaner and oil filter, H-radio, J-fender lamps, K L M- heaters, N defroster, and O-sunshine turret top. In addition, WWT was also used in 1939 for white wall tires and 6 or 6W for dual side mounts. 6 or 6W was also an option code for 1940. The accessory group option normally referred to wheel trim rings. Multiple letter codes for heater options were meant to differentiate between deluxe heaters, fresh air heaters and standard heaters. I believe 1940 had a specific letter code for under set heaters but I can't remember what the letter was. The option codes were intended to be used in conjunction with the body tracking number on the build plate. It was not unusual for options codes to be skipped on the build plates during production. Also, if the option was installed at the dealership there would be no code marked on the build plate. 1937 and 1938 used many of the same option codes as 1939.

Thank you so so.much ...that makes sense ...mine has has the wood grain mouldings and heater....

That's also what I thought initially ...but I've seen build plates with just the "O"stamped on the plate and others with just the" K"...

[Trying to ID my grandfather's car]

Hi Guys,

I only have this phot of my grandfathers car. He was a car enthusiast here in Australia. Im guessing

its pre 1940 because of the head lights not incorporated on the front fenders

May be a Mopar due to the single Windscreen (not s plit windshield like GM based cars?) and grill with horizontal louvers???

Not sure about the wipers operating from the bottom

Not sure if it has suicide doors

I cant make out the hood emblem either

 

Any help would be appreciated.

Hi Guys

Working on my thermostat and spring loaded valve body.

I bolted it in and have coolant pouring out of the top one of the bolt head.

looking inside the body I see a hole that the bolt passes by that the coolant is leaking from .

What is that hole for and should it be Welsh plugged ........
