IZH46M Lubes?

#1 Post by KevinS »

I just got one of these and I notice is there's a lot of moving parts. Everything is pretty dry except for the cocking lever, which is greased from the factory. The piston and compression tube looks like there's no lube on them at all. What would the recommended lube be besides moly and pellgunoil mixture on the pivots? Should I use some moly on the piston? I usually use pellgunoil on SSP and pumper guns but none of them have this many metal moving parts.

Thanks,
Kevin

A tiny bit of Pelletgun or silicone oil will do the trick.
Moly is for steel on steel only. The piston in the 46M is aluminum.

Thanks ETA. Would you lube anything else like the sliding latch on the breech or any other sliding parts?

Thanks,

A bit of light oil just enough to 'wet' the rubbing/contacts surfaces. Just don't over do it. Pelletgun oil is OK. Use a pin or tooth pick and transfer a tiny bit at a time.

Don't neglect the small inner valve seal on the IZH-46(M). Back in 2000 I had an IZH-46 and lubed all the pivot points with moly and lubed the piston seal with pellgunoil. The pistol was a used model and it already had extensive use from a national level competitor. After 6 months my pistol started leaking at the valve. I tore down the front end and pulled the seal. It was dry but looked fine. I wet it down with pellgunoil and re-installed it. The pistols worked fine after that.

My advice... lube the inner seal by applying two drops of pellgunoil into the breech port, close latch, and prop pistol so the muzzle is lower than the breech. This will allow the lube to reach the valve seal.

BAIKAL IZH-46(M) DISASSEMBLY INSTRUCTIONS

The following instructions were created as I disassembled my old IZH-46 about 6 years ago. The valve seal was leaking but I managed to perform the simple repair of a cleaning and relubing with Pellgunoil. The seal was completely dry.

Names and numbers for parts will be taken from the manual that came with the pistol. The parts diagram can also be found at http://www.eaacorp.com/diagrams-izh46lg.html

Back end:
1 - First remove the grip panels by removing the 3 grip screws.
2 - Remove screw #20. This is the small screw in right side of the slide(part #2).
3 - You can then disconnect the cover tie(65) by sliding the slide forward.
4 - The bar(7) can then be removed by slipping the rear through the notched out part in the slide(2). Rotate it out.
5 - You can unhook blocking lever spring(4) from blocking lever using a pair of needle nose plyers.
6 - Remove large drift pin holding cover lever(57) and blocking lever(3) in place. Hold these two parts together on removal so you remember how they go.
7 - The valve stem(17) should slide out with a little coaxing. You might have to pull the trigger if pistol is cocked. You also have to hold down the valve sear(14) with a small screwdriver because it blocks removal. The sear is only under spring tension so little effort is needed to hold it down.
8 - Remove main valve(9) and valve spring(13) from rear of pistol. Sear must be held down for removal of these parts.
That's as far as I went on the back end of the pistol.

Front end:
1 - Remove yoke(21).
2 - Remove 2 hinge pins[8]
3 - Linkages will slide out now, after the plug(23) and block(26) are removed. Take notice of how they all go together so you can replace the same way.
4 - Slide linkages and piston out of pistol.
5 - Remove drift pin in frame. I cannot find part # on this pin. It is the pin that goes through the cylinder(29). It is located below the "IZH-46" print. The pin needs a good punch for removal as it is very tight. I made a punch from an old allen key and hardened it with a propane torch.
6 - Remove cylinder(29) from frame by rotating counter clockwise. You can put a screwdriver through the hinge pin hole for leverage. A little heat on the cylinder will help. I danced a propane flame over the cylinder from a distance until it was very warm to the touch. Don't overdo this. Just warm it up.
7 - There is a rubber packing ring(35) in the frame that you will see when the compression chamber is removed. I removed it and lubed with Pellgunoil to ease reassembly.
8 - Next I made a small hook from a large paperclip and pulled out the valve seat(30) by hooking inside it and sliding it out. The valve seat in not fastened in but might be stuck on the lock(31). The lock is actually the inner seal that I wanted to look at.
The hook I made by straightening out the paperclip and bending a very short(approx 2mm) end at 90 degrees. This hook would enter the valve seat(30) and provide some pulling ability.
9 - Once the valve seat is out , I hooked the lock(31) and pulled it out using my paperclip tool. The lock is a rubber seal that is sandwiched between the valve seat(30) and the bush(32). I didn't need to remove the bush so it stayed in place.
10 - The slide(2) can be removed by sliding it toward the rear sight and pulling it upwards.The slide spring(12) will pop out to. You can clean under it and replace. No need for total removal.

That's about it. I may have forgot something but this is the process I recorded.

Notes:
There is no need to remove any trigger parts to get to the seals, which is a point that I like. My trigger is set up sweet and I didn't want to muck with it.

To clean out the old factory lube you only have to do a partial front end disassembly. Only go as far as removing the piston. You do NOT need to remove the compression cylinder(tube 29). Just use some paper towel and clean out the Russian lube and replace with Pellgunoil or Secret Sauce. The linkages and pivot pins can be lubed with moly paste for a smoother movement and longevity.

Crosman pellgun oil works fine for lubing the IZH-46(M) piston seal and inner seal. To lube the inner seal you need to put a drop or two in the transfer port and close the breech. Fire the trigger and prop the pistol so the lube can flow towards the muzzle. The piston seal can be lubed periodically for maintenance. When the cocking lever is opened the seal and piston can be lubed with a couple of drops of Pellgunoil.
