AK-50 air compressor removal tool set
Waterjet cut, welded, normalized, heat treated and plated, these two wrenches are faithul to the original Russian dimensions and materials.
Only those who have wasted a day on this task using the wrong tools will appreciate the right ones.
Five nuts and washers yield to the long curved tool with ease, but unless you have this short wrench, you'll be spending a lot longer than necessary on the sixth.
(If it's your first time tackling the job, we recommend removing the section of the exhaust that includes the heater muff, followed by the sheet metal blast duct which guides cold air onto the head of the compressor. Might seem like wasted effort until you have freed the compressor and need to maneuver it for removal or to get at that sheared coupling. )
And, if you've already attempted the job without the correct tools, you'll know that taking these six nuts off, was only half the fun.
Baffle, Oil Radiator Inlet, Yak 52
Don’t tolerate oil temperature needles in the low caution range when you fly - land and do something about it. Remember, however chilly you feel on the ground, what matters is the temperature of the colder air aloft, blasting across your Oil Radiator at 130 knots.
In combination with the radiator outlet door, this ground-adjustable Oil Radiator blanking plate will keep your Yak’s oil in the green in the coldest months of the South Western US winter.
Further East and into the Midwest, if your oil Temperature needle hasn’t moved into the green during the run up, you can shut down, remove the plate & flatten up to four of the flaps to block even more cold air from entering your Oil Radiator.
Just to get us all on the same page, this ground adjustable baffle plate is designed to be bent once - to find the sweet spot for your Winter conditions, rather than to be adjusted every flight.
How many times can you bend a flap before the material will crack?
Three times.
And don’t forget to remove this baffle when warmer Springtime weather comes...
Made from 5052-T32 Aluminum, riveted and anodized. Three rubber buffers, screwed to the rear face, prevent damage to the face of the Oil Radiator core.
Cylinder Base Nut Wrench, M14-P
When does a tool become...a precision instrument?
You actually know the moment you pick it up.
This wrench is a pattern of the field service tool included in Yak 52 toolboxes. The test of accuracy in reproduction wrench geometry is the cylinder base nut next to the sump, shown here.
But surely adding a half inch drive couldn’t hurt for accurate torque wrenching?
The factory spec for cylinder base nuts is 27.5 ft lbs ( Source: Termikas engine manual) but an informal survey we made of several well-respected Yak mechanics suggests many people are using closer to 45 ft lbs - the value for Lycoming cylinder base nuts. We tested this wrench to failure at beyond double that value.
Will you be able to break yours ?
If that’s what you set out to do, then certainly.
But if you treat this instrument with the same care as the other tools in your toolbox, then most likely it will neither break nor the socket’s 12 points become dull.
Not going to lie, we went down the Rabbit hole with metallurgy and heat treating on this one.
Want us to go into all the blah blah blah about grain structure and Brinell Hardness?
No, of course you don’t
You’ve already got a drawer-full of busted Chinese ones.
