I can't find any shops that stock the gun

and yes i can order it in

but at an automotive store they sell min grease guns and an array of tips but the grease gun is rated for 3600 psi... I don't want to assume that is sufficient although it seems like it should be

You inject grease until you see dirty grease ooze out somewhere and you are done.
There is no min/max psi it depends on how tight the seals are and how old the grease is.

Enjoy

finishline sells a grease gun that will fit the injector port on speedplay pedals.

http://www.finishlineusa.com/products/grease-pump.htm

fits 9/16 threaded grease tubes which are available at automotive stores.

Harbor Freight sells a three ounce grease gun which comes with a tip that works perfectly on my Frogs. Think I paid about $10.00

A Duelco refillable grease gun with it's standard tip also works well and provides plenty of pressure to force the grease through Speedplays. I use it on my Frogs. Here is one source:

http://www.biketoolsetc.com/index.cg...item_id=DU-LG1

These things also work great as grease dispensers to fill hub bearing races, headset races, etc. and keep the grease off your hands. You can buy grease in large tubes or containers (I buy Phil Grease that way) and refill the gun while keeping the rest of the grease clean. Bulk grease is also way cheaper than 3-oz bike shop tubes.

They're $5 and work fine. I drilled out the tip slightly to give a little more flow and am quite happy with the results.

Sounds like either the same or a knock-off of the Duelco.

I ended up with a mini grease gun from Canadian tire

I bought 2 tips one is 1/8 for an inch and the other is a needle tip that is an 18g needle

pretty sure the 1/8 will work but wasn't 100% sure so bought the needle tip as well

it came with multi-purpose lithium grease which I hope will work

personally, I would use the marine grade green grease.

white lithium grease doesn't seem to last as long and feels a bit thicker.

For $22 it better. However, the Duelco for $10 and the Harbor Freight knock-off for $5 do too.

A $2 plastic drugstore syringe works just fine. Get some marine grease and load up.

+1

I used a spare one lying around in the bathroom closet, it's now my official Speedplay grease gun. Total cost = 0$. Remove the screw + cap from pedal end, press in the syringe, push the plunger slooowly, wait for dirty grease to come out. Wipe clean, ride. Repeat as needed.

You could probably use the cake decoration syringe that's been sitting in your kitchen ever since Aunt Annie's 80th birthday when your significant one did that wildly decorated cake, but said significant one will probably make you swallow the grease you put in said cake decoration syringe. Stick to the drugstore cabinet.

Can you get grease to the rear bearings near the crank arm that way?

The grease gun (in any form) forces grease from to outboard side of the pedal through it's width until it extrudes out at the inboard side and you wipe off the excess off of the spindle. It HAS to pass through the inboard bearing.
