This manual has
HOW TO USE THIS MANUAL
two volumes of maintenance information you will need to repair and service the M36and M36E 1 Periscopes.
● Volume I - Troubleshooting
● Volume II - Maintenance
The organization paragraph in each volume tells you what information you can find in each chapter andappendix.
There are four ways to find any maintenance information you need:
● Index on the front cover which tells what information is contained in each chapter
● Table of Contents located at the front of the manual which has a complete listing byparagraph number and page number
● Fault Symptom Index ( Vol I, Chap 3 ) which lists the fault symptoms and shows where tolook to fix them
● Maintenance Task Index ( Vol II, App. B) which lists major assemblies, subassemblies andparagraph numbers of all maintenance procedures
Before doing any maintenance, you should read and understand HOW TO TROUBLESHOOT on page1-3. If you do not know the equipment well, you should read the section on description and data ( Vol II,Chap 1).
Throughout the manual reference is made to a Job Performance Guide 113-091-9000R (JPG 41 C)which helps you to develop skills in doing the maintenance tasks.

1-1. SCOPE
This volume contains troubleshooting requirements and procedures for direct support and general support(DS/GS) maintenance of the M36 and M36E1 Periscopes. See Volume II for maintenance procedures.
1-2. ORGANIZATION
a. Chapter 2, Checkout Procedure, gives you flow charts to follow to check that the periscopes areworking right.
b. Chapter 3, Fault Symptom Index, lists the fault symptoms and where to look in this manual to fixeach one.
c. Chapter 4, Fault Isolation Procedures, shows you step-by-step how to troubleshoot the faultsymptoms found in Chapter 3.
d. Appendix A, Wiring Diagrams, may be used to help you find the cause of a fault. Theycan be used to trace signal flow or to find out what a voltage should be.

1-3. HOW TO TROUBLESHOOT
The following steps tell you how to troubleshoot. A diagram of these steps is on page 1-3.
Do a visual check and list any faults on DA Form 2404 before making repairs. See Vol II,Chap 3 for what to check for.
If you see any faults that may affect the checkout procedure, fix them now. This does notmean small things like painting scratches.
Do the checkout procedure in Vol I, Chap 2 from the beginning until you find a faultsymptom.
When a fault symptom is found, go. to the chapter noted and follow the maintenanceprocedure given there. If you already know the fault symptom, look at the fault symptomindex in Chapter 3 of this volume. This will also tell you what to do.
After the fault symtom has been corrected, do the checkout procedure in Chapter 2 again.This is to make sure that all fault symptoms have been corrected.
If all fault symptoms are now correct, do the remaining maintenance tasks on DA Form 2404.
Do the final inspection given in Vol II, Chap 9.
The job is over and the good assembly is sent back to service.
If all fault symptoms were not corrected after step E, the bad assembly is sent back to the. .depot for repair.
The sample fault isolation procedure ( para 1-5 ) shows you how to use the flow charts in this volume.

Description
This is the symptom shown in the Fault Symptom Index in Chapter 3.
Block number. Tells you the number of the block on the page. Block numbers startover at every page.
This is a note. It gives useful information that can help you in doing the procedure.A note will always come just before the step of the procedure that it is about.
A warning will be labeled at top of block. Always follow the instruction in this kindof block carefully: If you don’t, you may be injured or injure someone else.
A caution will also be labeled at top of block. The instructions in this kind of blocktell you what to do so you will not damage equipment. Be sure you always followcaution instructions carefully.
Index numbers are found in the procedures and the illustration to help you find theconnector, switch, knob, etc. The illustration will always be on the same or anopposite page. Remember you will never have to turn the page to find theillustration.
The circle is used to send you to another sheet of procedure to keep ontroubleshooting. The top number in the circle tells you what sheet to go to. Thebottom number tells you what block on that sheet to start with. For example:
means that you should go to sheet 3 block 01 to keep on the procedure.

This tells you where you came from. For example 2.03 means you came from sheet2, block 03.
The top part of the box tells you what to do. The bottom part tells you how to doit. After you become more skilled at troubleshooting and know more about theequipment, you may find that you only need to read the top pan of the box.
This diamond shaped box is called a decision point. It asks you to answer a YESor NO question, after doing the what-to-do statement. If the answer is YES, youshould go down the YES branch. If the answer is NO, you should go down theNO branch.

Section 2. DESCRIPTION AND DATA
1-3. DESCRIPTION
The M36/M36E1 is a monocular periscope for the tank commander. It is part of the fire control system inthe M60 series tanks. The M36 periscope is mounted in M119 periscope mount. The M36E1 is mountedin M119 E 1 mount. A link assembly interconnects the periscope’s sighting with the tank machine gun.The periscope is made up of three main parts:
a. HEAD ASSEMBLY. This part contains an entrance window, a prism (mirror) which ismechanically connected (by way of link assembly) to the gun elevation drive and a mounting plate bywhich the periscope is attached to the periscope mount.
b. BODY ASSEMBLY. This part contains a unity power mirror between entrance and exit windows.It houses the daylight viewing optical system which is collimated to the body housing to insureparallelism in the line of sight. It also houses the night viewing optical system which is the third mainpart. The M36 night viewing unit is the Infrared Body Assembly. The M36E1 night viewing unit is theElbow Assembly.
c. INFRARED BODY ASSEMBLY. This monocular telescope is used for infrared sighting. Withinthe assembly is an integral reticle projection system positioned by boresight knobs.
d. ELBOW ASSEMBLY. The elbow or image intensification assembly amplifies available light bymeans of an image intensifier tube and power supply, making objects visible without the aid of asearchlight. Its optical system is like the Infrared Body Assembly.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
