Hello,
I was wondering if anyone can tell me how to remove the trim that’s installed on a short Tokheim 39 above the door?


Also, does anyone have any tricks in removing the sight glass? I would try heat but was afraid of breaking the sight glass. The screws are seized.


Thank You,
John

An impact screwdriver should do the trick

Yah I tried but shattered it lol. I’ll try again after more soaking. If not for glass I would heart it and use wax. That works every time but afraid I’ll break them.

Been a while, but I think I've used a torch on the nuts holding the trim. It's very easy to break the studs off so torching them some before using a ratchet or wrench is best option. I dont recall having difficulty removing the bolts for the site glass after using penetrating fluid. I probably used a properly sized flathead with a crescent wrench to twist the screwdriver.

In my experience, remove the whole top first. Only 4 bolts. Once removed you can turn it over and work on the screws. Use a good rust release like Kroil liberally. Then use an electric impact driver with the proper socket. They will come loose. Some might break but replacements can be found at good auto paint stores. As for the site glass screws. Once the top is off, you will have access to use vise grip pilers to grasp the screw top and break the machine screw free. Regards, Paul www.severngaspumps.com

Very carefully...ok, somebody had to say it......

Absolutely, take the top off the pump before doing anything else.


Already did above...

Just did this the other day on my 39 Short. There should be seven nuts on the back side of the trim. Don't be surprised if even after soaking in blaster you wind up shearing the nut off the stud. I was successful in removing 4 of the 14. Keep the broken t-slot fasteners. I ground off the remaining threads, tapped a new hole and welded in a new section of all-thread. It took a little time, but I didn't have to hunt around looking for an alternative fastener. Also, you'll likely find a heat shield attached to two of the fasteners. Mine were rusted out, so I used them as a template and made two new ones out of sheet metal. Let me know if you have other questions.

With regard to the sight glass bolts, I'd let them soak as much as possible. When using heat, remember that the pump was manufactured in the late 40s and very likely completely coated in lead based primer.

I do exactly what gasmansgp does above. Take that top off first. Makes it way easier.

I have cracked site glasses with heat before, so try soaking it for a few days. And like mentioned above, proper size screw driver with a lot of forward pressure and the crescent wrench.

As far as loosening rusted bolts & screws, go with Kroil! As mentioned previously, KROIL! If possible Soak Everything in Kroil days before you tear into it. I've tried all of the products. Kroil is BEST by far. Mark

Thanks for all the assistance. I pulled the top and sides to get at the trim. I was thinking it was going to be like an automotive trim with a strung clip to remove it. This was very straight forward in the end.

With the sight glass I had already been soaking in Kroil for a week. Then used a panel vice attached to a screwdriver. No luck yet. This is why I was wondering if anyone used heat. I'll keep soaking with Kroil for now...

Thanks,
John

John I have had success with a couple of different techniques. I use either a metal chisel or a plastic handled screw driver as close to the slot width and diameter as you have and then I drive on the chisel with a hammer as if driving a nail. That seems to jar all of the threads of the bolt. I repeat that several times and soak again. Ironically I have also had some luck going tight rather than loose to start the screws moving.

I've got to agree about trying to tighten the screws a bit to loosen them up. It's worked for me in the past. Brady
