Tribal HRP Refirbishment....

[Edwin]

Ok, I had to repair four Tribal HPRs, and here is what I did:

Tools Needed:
1. C-Clip Removal Tool
2. 5/32 Allen Wrench
3. 1000 Grit Sand Paper
4. Small Shaft (less than 1/4"). I used a nail from a nail gun, and jus cut the head off.
5. Tape
6. Gold Gup
7. Dow 33
8. Rebuld kit for Airsoldier (Possible)
9. Special Made Puller
10. Drill

A. Remove the C-Clip.
B. Remove the Down Regulator Plunger with the puller (part #9), and spacers, springs, washers and etc.
C. Remove the Down Regulator Exhaust Valve also with the puller.
D. Remove the Down Regulator Adjustment Screw.
E. Clean the striped Regulator.
F. Tape a piece of sand paper to the shaft, chuck it to your drill, add a few drops of GC oil (any oil will do), and sand the area where the Down Regulator Exhaust Valve sits to remove all the burrs.
G. Add a chamfer to Down Regulator Exhaust Valve as shown in Airsoldier Tech Notes:

H. Replace damaged or worn orings, or replace everything that is included with Airsoldiers rebuild kit.
I. Reassemble in reverse order.

Note on Puller:
I used a 316 Stainless Steel Welding Rod, made a triangle handle on one side and bent the other end about 110 degrees. You must make a sharp bend at the end. I used a needle nose pliers and also a vice and a hammer to get the sharp corner. I then used a grinder to get the right diameter to fit in the seat.

It works great!!! Much better than trying to use a paper clip to push the valve out from the adjustment screw hole. I think that is where half the problems come from. When you push with a paper clip, you can actually scratch the inside where the valve slides up and down.

Ok, I have always had problems removing the HPR and macroline fitting ASA adapter. So here are a few things I found that helped me a lot.

The two tools that I like to use are:
1. Soft Jaw Channel Lock Pliers (Snap-On)
2. Small Spanner Wrench (MSCdirect.com) commonly used for adjusting micrometers.

The spanner wrench fits into the vent hole of the HPR close to the top threads and/or the hp adjustment screw. Be careful when using the spanner wrench in the hp adjustment screw hole as you can damage the threads if your not careful.

To take off the HPR from the ASA adapter, just use the spanner wrench in the adjustment hole and twist.

To take off the macroline fitting ASA adapter, put the spanner wrench in the vent hole near the top of the hpr, and the soft jaw pliers on the knurled cap,
and twist.

If you have any suggestions to make this better, just PM me and I will edit.

A small crochet hook may also work as a seat puller, as that's exactly what yours looks like! I always used a paperclip myself, but always bent it into a hook and pulled the eat out of the top - never pushed thought the adjustment hole, as I think scratching that surface causes problems as well.

One trick that I like to use for pulling out the piston is to thread in a 4-40 tap down the central hole of the piston - you can actually do it with just your fingers in most cases, and it grabs the piston well enough to pull it right out!

Thanks Blue. Let me did out my knitting stuff and see if I can find one of those!!! :cheer3od:
