1930-33 VL oil pump spring

[sny]

Got my oil pump all apart. It was really gunked up and stuck. Much thanks again to Steves book because I would have never figured out what was in there. After cleaning it up it all looks to be in good solid shape except one broken spring.

Questions:
Are there really two different sized springs?
Anyone know where I can get a replacement spring? (the longer one if they are diff sizes)

i'll jump in here and see if i can stand corrected.

Looking in my 27-31 parts book, i believe the spring you are referring to is 670-22, "oil plunger spring, later 22-31."

in the case of JD models, the same part number is called for in the 1922-27 parts book, as is the "oiler plunger" pn 668-22.

These springs need to all be the same length for allowing the plungers to allow oil to enter into and through the mechanical oiler.

if i understand correctly the function of the oiler, these springs push the plungers against the swash plate that is part of the oiler body. The springs sohould al be teh same length to put pressure on the swash plate in order for the pump to work properly. Different length springs are due to age, wear and fatigue resulting in shortening or breakage of the spring(s.)

i just ordered and received earlier this week from McMaster Carr the springs near identical to factory springs; the pn for these springs is 9657k282, they are slightly longer than original.

Thank God for McMaster Carr. I sent them a letter of gratitude once, after getting a weird, esoteric object, in lightning fast time. They wrote back to me and thanked me for my business, even though I'm small potatoes, and it was from a real person. Absolutely, first class company. Sorry for the detour testimonial, Steve.

Eric, not at all. i benefit from your every post.

Steve, Excellent info! I also love McMaster Carr, they have saved the day so many times for me!

well, i'd like to claim it as my original idea, but i think i found the MC pn for the springs on jdyahoogrps, seems Joe Drociuk of BC gave me the tip.

Just to confirm the three 670-22 springs are all the same length. I made a batch but they are all sold out now. Don't forget the little pistons fit with the rounded ends out. There are tips in the Technical section of the VL Heaven Website for anyone experiencing over oiling with these pumps.

Thank you! I'm ordering now... and wow they really do have a lot of other great parts and pieces available on their website.

Thanks! Looking forward to getting to the adjustments and tuning stage! I'm now officially done disassembly and with a little more parts gathering I'll be on to machining.

Got my springs in the mail. They are slightly bigger but fit perfect. Thanks again for the tip.

That looks like the rarely seen 1933 plunger with the jet for the one-year adjustable chain oiler. Nice.

I have been looking for that late 33 plunger carrier for almost 2 years without any luck. Oddly sny, your pump body does not seem to show the oiler adjustment screw required for that style of carrier.

[Steve Slocombe]

I have the correct plunger carrier for 1930 if there is a deal to be made here...

The pump body does have a threaded hole with an adjustment screw and spacer on it. You can see the screw in the bottom left of the first pic I posted. I played around with it allows you to adjust the angle of the cam/flap thing.

The adjuster for the chain oiler would be at bottom right of the pump.
