Simple Jensen Repair Question

Simple Jensen Repair Question
Posted by mikethenerd2 on 13 Apr, 2020 11:51
Hello all,

During a move, the boiler on my wife's Jensen 75 got damaged. Only the top of the boiler is damaged, the rest if fine. So I need to put a new boiler on it.

I've never attempted to do any repairs on my Jensens, so I apologize if my question seems silly. Am I better off (is it easier) to replace the boiler and the firebox together? Or is replacing only the boiler just as simple to do? Obviously, Jensen sells (once they reopen) both the boilers themselves and the boiler attached to the firebox.

Thanks!

Mike

hi Mike, it is easier to replace the boiler and the Firebox at one time, allbeit twice as expensive. If you have a1/8" drill bit ,and a drill ...you could drill the rivets out if in fact it is riveted, and bolt it back together using 6/32 nut/screw

Replacing just the boiler is very easy to do. They sell the rivets/eyelets and you only need a hammer, Phillips screwdriver, punch and a block of wood to replace them after drilling out the old ones. Or you could even go with screws/nuts like the 76 uses for easy disassembly/cleaning in the future.

Thanks for the replies. It looks like the boiler for the 75 sells for $76.40, and the boiler + firebox sells for $87.30 (Jensen website). So I will probably just replace both. I just hope Jensen is up and operating again soon!

By the way, do you have a picture of the boiler damage? If it was the whistle or SV that got pushed in, those dents can sometimes be pulled out.

The engine is packed away at the moment so I don't have any photos. But yes, the whistle got left on it and the damage was from something pushing the whistle while it was screwed into the boiler.

I'm curious, what is the procedure for attempting to pull a dent out?

Many thanks!

If the dent is around a fitting, I have a special long rod with the correct thread , I hold the boiler firm in a fixture, screw in rod ,apply gentle heat to the effected area.....and work the dent out.

If the thread merely is thrown over, i´ve managed to straighten dent and thread as is.
No heat or anything, just a 5/16" x 24 threaded bolt screwed in there, and a gentle twist/pull back to upright position.
I find that it works best for me, to fix the bolt in the vice, and twist/pull the boiler itself.
