Well new seals, wiper and Air valve assembly arrived this evening for my Daisy 747. Ordered 2 seal kits and 2 replacement valves from Daisy. I've had it for several years and have run several thousand pellets through it. It was still shooting well but was struggling to cut clean holes in the paper and figured I give the old gun a once over.
Not as bad as I was thinking.
- Removed the grips
- Removed 3 screws in the receiver side after insuring the safety was on. If not, a very tiny ball bearing and spring will go flying. I was lucky and found mine in the carpet.
- Once the three screws are removed the gun falls into 4 parts. The barrel and cylinder, Sides and Grip frame and trigger housing.
- Then I removed the rear sight by unscrewing the adjustment screw to free the nut. When your ready to reassemble there is a slot the nut will fit into when the 2 halves are properly aligned. This is a must or you will fight it trying to get things back together.
- Removed the screw at the front of the cylinder holding the cocking lever and front sight.
- Removed the barrel, front sight and cocking lever
- Clean and replace seals, wiper and Valve
Seals were not in to bad a shape but you can see the old valve compared to the new one and the wiper was crumbling.
My first air gun repair
Cant wait to try it out if the rain stops tomorrow.
