There is two screws holding the barrel & firing mechanism to the stock. On the underside of the stock, remove the screw that is in the stock forward of the trigger & then remove the screw at the back of the trigger, leave the front trigger screw in for now, the stock & the barrel/firing mechanism will separate from the stock. Next with the breach closed, remove the plastic lug at the back end of the barrel/firing mechanism you should be able to pull it out with your fingers. Then with the barrel upsidedown (sights towards the floor) lift the back of the trigger mechanism up & slide back removing it from the breach, exposing the underside of the breach clean everthing you can in the trigger mechanism. Now for the trickey bit. With the barrel still laying flat sights down, you need to slide the bolt halfway back & hold it there as if in the motion of cocking the gun. Using 1 hand to hold it halfway back use your other hand to gently lift the bolt away from the breach enough so that you can slide it forward gently leaving the spring & guide shaft in the rear part of the breach. The piece you would usually grab & pull to cock the gun will fall away be carful not to loose it. Clean everthing you can & repeat step by step in reverse to reasemble your gun. Pretty simple hope this helps Happy shooting
Your Glenfield model 75C will go for between 50-75 dollars on today's market.
The Glenfield model 75C is a carbine variant of the Marlin model 60 produced for 1975 to 1992 by th m Mrlin Firearms Company under the name of Glenfield. Differences include shorter 18 inch barrel compared to the Marlin's 20. Length of pull on the Glenfield is shorter. The Glenfield also has a shorter and lower capacity magazine tube. The Glenfield hold 9 shots in the magazine, while current Marlins hold 15. Nearly all parts are interchangeable, and the Glenfield can be converted to modern full sized Marlin 60 specifications if desired.
Your Marlin model 75C was made in the year 1976.
The Glenfield 75c .22 long rifle is a fine rifle. simple, short, with a squirrel on the handle if you are lucky. they retail used in gun shops (2008) for around $100. I purchased mine in Oregon for $99. The shop had the Glenfield 75, with the longer barrel for $89. I prefer the shorter barrel of the model c, it feels really ballanced and is great for woodland hunting. -whooise
Your Marlin model 75C was made in the year 1976.With the serial number provided.
Your Marlin model 75C was made in the year 1980,with the serial number that you supplied.
Your serial number indicates that your model 75C was made in the year 1976.
I believe that this model was made from 1989-1995.
There is no difference internal to the two rifles. The only difference is barrel length. Both have 14-round tubular magazines. The model 75C has a carbine length (~19") barrel. Model 60s produced when the 75C was in production have a rifle-length (22") barrel, but the current Model 60 has been shortened to 19", making it seemingly identical to the old 75C. My 75C from 1987 looks identical to the model 60 on the current Marlin website.

If you subtract the first 2 numbers of your serial number from 2000,you should be able to get the year of manufacture.I can say that the model 70HC was made from 1989-1995.But I can find no serial number data on the model 75C.
The booklet that came with the Marlin 75-20 shows it to be a 75C.
model GA22 ( great american 22 cal) first production 1983 same as marlin model 75C
