Please Note.

It is recommended that installation of any Belsales or EVO^tm Parts is carried out by a trained and qualified airsmith. Incorrect installation of any component onto or into a paintball marker or any accessory may result in serious injury or death. Belsales LTD, its staff or any of its subsidiaries cannot be held responsible for any result arising from improper installation. If you are at all unsure about the correct installation procedure for any Belsales or EVO^tm product we strongly advise that you seek professional assistance or contact any of the technical staff at Belsales LTD using any of the details provided on the contact page. Before starting any work on your marker, please read and carry out the instruction in the section marker "safety"

The EVO^tm 44 Magnum Ram is a replacement Autococker ram designed to give increased performance to the re cocking cycle of your Autococker. The EVO^tm 44 Magnum Ram is made by Belsales LTD to their exacting standards of dimension, surface finish and assembly to provide a ram cycle far smoother and more energy efficient than a standard part. Further to this; the EVO^tm 44 Magnum Ram provides two different orientations of inlet/outlet port on the free end on the Ram making it easier to set up and facilitating the attachment of "Quick Exhaust Valves" (QEV's).

The EVO^tm 44 Magnum Ram comes fitted with two 10-32 UNF barbs and a single 10-32 UNF blanking plug in the unused port. The blanking plug can be used in either of the two free end ports (so long as an exhaust/fill attachment is fitted to the other) with no appreciable detriment to performance.

The fitting of this part requires a MODERATE degree of competency in mechanical work. If you are unsure as to your skill level as an airsmith we recommend that you seek professional advice or services from a qualified airsmith.

To fit this part you will require some or all of the following tools:

• Dentists pick or similar
• 1/2" Spanner
• Hot air gun / Paint stripper / blow torch or other "point" heating device
• Vice and pliers or 2 X pliers with SOFT JAWS (Fibre / Plastic or other soft jaws )
• 3/32" Allen key and 5mm spanner (only required if swapping blanking plug for fill nipple on free end of Ram)
• Weak thread locking compound
• Strong thread locking compound

• Fully de-gas the marker, including firing off MULTIPLE shots after the air source has been disconnected to make sure that the regulator has been FULLY depressurised.
• Remove the bolt from your Autococker by pulling out the pull pin and extracting the bolt from the rear end.
• Unscrew the cocking rod and extract from the rear end.
• Pull the cocking block rearward and grip the pump rod gently while rotating the cocking block anti-clockwise in order to remove cocking block from pump rod.
• Use a small pick to lever the hosing from the barbs on the old Ram. You may have to lever off the "top hats" on older models (small brass shrouds that clamp over the hosing fixing it onto the nipple).
• Gently unscrew the old Ram from the semi-block with pump rod still attached.
• Grip the old Ram shaft firmly with the soft jaw vice (or pliers). Use the blow torch or heat gun to loosen the thread lock compound that holds the ram to the pump rod.
• Unscrew the Ram rod from pump rod taking great care not to damage either component.

 

• If you are planning on fitting QEV's to the Ram then before you start assembly of the Ram to the marker it is necessary to remove the barbs from the ram. Do this now if required.
• Using the strong thread locking compound install the ram onto the pump rod, screwing the two together until fully inserted. Be very careful whilst gripping the Ram shaft not to score or damage the shaft in any way as this will lead to leaks developing from the ram and decrease performance significantly. The Ram should be secured to the pump rod HAND TIGHT only, do not use any tools!
• Insert the ram and pump rod assembly into the semi-block by screwing the threaded ram collar (with a little weak thread lock compound) into the semi-block. Ensure that when the Ram is all the way retracted (shaft fully into chamber) that there is enough thread on the pump rod protruding from the back of the body to safely attach the back block.
• Once the Ram is attached to the semi-block, extend the pump rod fully and screw on the back block. Rotate the back block one full turn clockwise at a time, after each revolution, return the Ram to the forward position to check the gap between the back block and the body. If there is still a gap then screw the back block onto the pump rod a further full turn. Repeat as required until the back-block JUST touches the body. Do not screw the back block all the way onto the pump rod unless it is required as explained above.
• If QEV's are being installed, do that now (see Q.E.V instructions).
• Attach the hosing from the three-way (or solenoid) to the correct Ram nipples. If using a low pressure setup then "top hats" are not required. On older, higher pressure cocking system, securing "top hats" may be required.
• Insert cocking rod (do not use thread lock compound).
• Insert Bolt and securing pin.
• Check that marker cocks and fires by hand.
• Check all fittings and fixings before gassing up the marker.
• Gently gas up the marker, pointing it in a safe direction.

Be very careful not to damage the shaft of the Ram during installation. Damage to the ram shaft will cause leaks and poor performance. This is not covered by any warranty.

Be careful not to overheat the ram shaft if removing thread lock compound. The Ram contains some precision fit O rings and seals that if damaged by heat may cause leaks and poor performance. This is not covered by any warranty.
