Hi

I've just picked up a nice 1988 model. Excellent blueing and wood. It's shooting about 750-800 judging from the cleanliness of the wadcutter's holes in the target.

The problem is it's quite twangy. I bought a new spring and seal and tried to tear into it but it's not as simple as an HW with a Rekord trigger. The trigger workings are external and I can't understand where to put the rear of the spring compressor. If I remove the safety, all I can see is the trigger assembly not the usual plug in the back end of newer Diana's.

It shoots great. Should I squirt some oil and leave this one alone??

Thanks

This is one gun that really benefits from a Maccari spring and tar. I did mine this spring and the difference is incredible. The only problem is I'm out of state right now and don't remember what I used between the spring compressor and the gun. I hope that someone will step in here and help you out as it is really worth the time to work it over.
Good luck!

is similar to the 34 teardown:

You should manufacture a block of wood that fits over the safety (and the safety fits into) that the compressor can ride on. It took a litle time for me to make it but it saved any damage to the safety and allows you to get into the gun very quickly.

I have an Original 45, not a new 45 t01. The new 45's are essentially a new 34 in an old style stock.

The Diana 45 is an old gun, and the trigger assembly is outside the compression tube.

I don't think the breakdown is the same as the 34

You are correct the internal parts are very different. You can check the Chambers site to see the differences I believe. The 45 is not a difficult gun to work on but a spring compressor and some mechanical abilities on your part are both very helpful and recommended.
Good luck!

I'm sorry if I mislead. My 45 is from 1981. Definite old style. I also have a 34 but have not torn it down. I used the 34 teardown as my guide and and guess I was a little intuitive and a little lucky. I thought they were pretty much the same except for the leather seal. I'm curious, where did you get the new seal for the old 45? Did you buy a synthetic seal as a replacement? Everyone I talked to (including JM) told me the original seal soaked in a good chamber oil should last forever. RWS said the new piston with lather seal was like $90 (one piece, not separate). All were correct about the old seal. It will probably last forever.

The leather seal was from Airgun Express. They were the only ones that had one. I tried RWS in NJ but they had it on backorder.

I paid 25 bucks for the seal and wound up not needing it. The old one soaked up nicely and was worn in.

Thanks for your help. This gun was well worth the effort. It was in almost mint condition except for the spring twang. Now, it's just pfutts at 600fpm
