Model 34 DIY "Tune"

Slide 2

Objectives: Install GSI Spring Kit (Jim Maccari) Remove old oils and reapply JM tar and Moly Paste Refine trigger for smoother activity and lighter force weight Disclaimers : I am not an expert airgunsmith; I am essentially sharing what I did to settle my Model 34 for individual use. Despite the fact that these methods were done in a way I felt sheltered and capable, this doesn\'t infer in any capacity that they are protected and revise. I don\'t consider this method to match a tune by a skillful airgunsmith, yet it had a critical effect on my weapon. It would be ideal if you be brilliant – ensure the firearm starts uncocked, evacuate the degree mount in the event that you have one, and when packing the spring, never point the end at yourself. At all focuses in this procedure be exceedingly cautious to not scratch the dye or wood segments of your firearm. I put a few little scratches in mine, and I thought I was being watchful. Despite the fact that I did a lot of "homework" on this method, and I adhered to the essentials, a few things COULD BE WRONG. So don\'t point the finger at me if your weapon is distinctive or I drove you to committing an error. I construct this in light of systems illustrated in the chronicles of the yellow discussion. This technique ought to be the same for the Diana Model 34 and 36s, and comparative for the Model 46 and 48.

Slide 3

Removing the Action Remove the front stock screws. Investigate strings painstakingly for harm, and supplant if either the male or female threading demonstrates any harm. Try not to lose the star washers under the screws. Expel the back stock screw. Painstakingly slide the metal activity out of the stock. Evacuate the wellbeing spread. Investigate the stock – search for where the stock reached the activity – close to the screws and along the activity tube. In the event that you discover confirmation of any uneven weight or contact, deliberately document or sand the stock to improve a fit. I did next to no change to my stock.

Slide 4

Removing the positioning lever From this point on, I put a cardboard box top on the workbench and worked over that so any free pieces didn\'t move away. At $5 each much of the time, you would prefer not to call Airgun Express to supplant a lost screw or e-cut. Place a screwdriver on one tip of the open side of the E-cut. Utilize another restricted screwdriver to press the other tip of the e-cut. The clasp will pop free – don\'t lose it. Most likely a superior methodology is to locate a slender, ½" wide question that fills the width of the hole in the positioning lever and utilize that to push down both purposes of the E-cut on the double. Push the pin through and remove the positioning lever.

Slide 5

Removing the barrel Remove the turn fastener and nut. There is a flimsy washer under the leader of the turn jolt – don\'t lose it or harm it. There is still a sleeve holding the barrel set up. Turn fastener, washer, and nut Sleeve

Slide 6

Barrel Pivot Sleeve and Washers Push the sleeve out utilizing a non-scratching instrument. The barrel détente keeps somewhat pressure on the barrel when in the terminating position, so it turns the barrel to a half-positioned position. Two washers that fit into sections on the barrel piece will fall free – they have sharp edges, so don\'t give them a chance to scratch anything. Grooves for washers Spring washers Sleeve Now is an awesome time to clean within the barrel with Goo-Gone utilizing a barrel patch and non-scratching pull-through. Put the barrel aside.

Slide 7

Receiver and Safety The trigger get together is held in the activity by two shear pins. Expel the back one first utilizing anything fitting to tap it through. To expel the front pin, you need a spring compressor to push on the distending part of the trigger enclosure and take the weight off the pin. Wellbeing Switch Pin Note: In the past I ground off a side of the body (yellow line) to permit evacuation of the security switch pin. This offers the benefit of evacuating the security now so it\'s not in the way when compacting the spring. Trigger Cage where it stretches out past activity tube Rear pin Front pin

Slide 8

My straightforward spring compressor On a Model 34, the spring is held under moderate pressure. This apparatus worked for me and just cost $10 for the strung bar, bumper washers, and nuts. I recommend utilizing greater/more grounded end obstructs than mine that have less risk of part. The other impediment is that it\'s moderate and repetitive fixing the wing nuts. Fix the wingnuts until it starts to cozy, however not very tight. Tap out the back pin, then the front pin. End obstruct with washers, nuts on both sides to secure bars Tape on strings to ensure weapon Rear Pin Wing nuts Front Pin Hole penetrated in end square to take into consideration wellbeing switch (covered up)

Slide 9

Piston Removal and substitution Back down the strain on the wingnuts until the pressure is no more. Expel the trigger gathering and put it aside. There is no compelling reason to dismantle the trigger get together on the off chance that you are just introducing the GSI pack. Pitch the old spring, back aide, and back aide washer. Degrease or clean within the chamber utilizing whatever you can repair. I utilized shop paper towels wound up to clean within. I didn\'t degrease the cylinder due to its cumbersome shape and the numerous pockets for it to hold degreaser. I supplanted the cylinder seal with another one by prying off the old seal and squeezing the new one set up. Make sure not to harm the edge of the seal. I connected moly glue instantly behind the seal. I additionally utilized little records and a deburring device to round the edges of the load at the positioning lever and trigger ranges. I cleaned the spring closes, delicately connected moly glue within and outside of the cylinder (however not on or in front of the seal), and some moly on the back aide where it touches the spring. I likewise rubbed the tar softly over the outside of the spring, avoiding the first and last curls. New cylinder seal (blue) Deburr the edges at these two openings

Slide 10

Trigger Improvement I endeavored to smooth my trigger since the drag was so unpleasant out of the processing plant. Begin by dismantling Pin 47 and expelling the trigger and trigger spring. At that point expel Pin 48 and burn 49. Be mindful so as to not lose the spring 50 which puts strain on the burn. I then cleaned the base face with a scrap of emery fabric. This significantly lessened the trigger force and expanded its smoothness. I didn\'t take photos of my trigger work, too bad. I was presumably diverted by the job that needs to be done. It\'s fundamentally a matter of pulling pins and not losing the springs all the while. Shine this base face

Slide 11

Trigger Reassembly Begin with 33. Embed the catch balls (34) in the openings and after that slide the get together into 32 so that the balls won\'t fall free. Embed the get together into 37, and slide pin 55 into the space of 37 and the opening of 32. Embed spring 35 and aide 36 together into the get together. Set the back face of 36 into the opening with the goal that it touches both 37 and 33 similarly. Crush the spring into the opening and over the tab on the top back of 32. I utilized a flathead screwdriver to clutch the 3 rd loop of the spring and my thumbs to keep the spring from popping free. Try not to give it a chance to shoot over the room and get lost. Slide the plastic sleeve 31 over the gathering. Front Back

Slide 12

Trigger Reassembly Set section 52 into the trigger and slide the pin in sufficiently only to catch one opening in 52. Utilizing a flathead screwdriver or other limited instrument, push the spring 53 into that corner and utilize pin 54 to catch it. Presently slide pin 54 in totally. Holding section 49 with a needle-nose forceps, set it into the gathering and catch it with pin 48. From the back of the get together, snare the highest point of spring 50 on 49, and push the base of 50 into the lodging until is snaps into the break. Catch trigger 45 with pin 47, then push spring 51 set up between the knock on the trigger and the knock in the trigger lodging (it will be specifically underneath spring 50, however embedded from the inverse side). Front Back

Slide 13

Trigger Reassembly The wellbeing ought to in any case be a gathering of parts 38, 39, 42, 43, and 44. Once the trigger gathering is mounted on the firearm, slide the long tab of 38 over the pins 73 and snap it into the back pin 73. At that point slide pin 41 into one side of the security gathering. Take spring 40, permit the snares on the base to hang over the section of 39&40, then bend the inverse side of the spring to a vertical position pushing on the posterior of 39. The center of the spring will tend to push out toward the back – push it in and get the loops with pin 41, then push pin 41 the distance in. Try not to give spring 40 a chance to shoot free and get lost. Guarantee the security accurately bolts the back of the trigger when locked in. Front Back

Slide 14

Reassembly and testing Reassembly is the inverse of dismantling ;o) I really reassembled without my spring compressor – I basically held the breech end of the chamber and squeezed it down on a 2x4. On the off chance that your security switch is set up, don\'t harm it. I discovered it wasn\'t hard to put enough weight along these lines to get the front pin in. Simply hold it so it won\'t slip and pop you in the mid-section or cut your hands. Degrease all the stock screws and utilize blue Loc-tite on reassembly. Be cautious positioning the weapon the first run through. On the off chance that anything in the trigger is not right, hope to discover now. Since the trigger ought to have a lower pull weight, check it won\'t fizzle. Take a few shots at short proximity since your POI will change, and it\'s most likely best to shoot twelve overwhelming pellets (Kodiaks) to diesel any lubes that may have gotten into the chamber.
