On one of the 710M's I bought years back, I had a similar problem with lack of braking in one circuit. It turned out that one of the Static Pressure Valves, part # 7103366220, had been installed backwards preventing the flow of brake fluid. The attached photo has the 2 valves marked with arrows. Wor...

Possibly also check the intake manifold balancing hose under the engine tin. Group 1-35, item 60 in the parts book. It maintains equal air balance between the front carb manifold and the rear carb manifold. The hose is exposed to heat from the cylinder heads and begins to degrade over time. IMG_3154...

I have no experience with Volvos but have often found suitable seals, weatherstrip, etc. for other projects from this company: https://www.steelerubber.com

I converted to the civilian ignition with Perrtronix, then to PinzSSI and have been using NGK BP6RES plugs with both. I replace them every 5000 miles since they are relatively inexpensive. They never look very worn. Hope this helps.

From the Owners Manual, Page 150. This is of course referring to the original military spark plugs. If you have converted to the civilian ignition with conventional spark plugs, your mileage will vary.

I've used CRC STA-LUBE SL24239 85-90W in wheel drives and differentials for over 10 years in multiple Pinz's and have experienced no issues. Disclaimer is that I'm not too hard on my Pinz nor do I put on many miles in a year. Looking through the forum archives you'll see many opinions on appropriate...

The sender has a knurled nut (on the right in your photo) that is screwed to the larger nut (on the left in your photo). Hold the left nut with the appropriate wrench and use a channel lock pliers to loosen the knurled nut. >> Don't lose the short piece of inner cable that fits into the sender << ht...

The part number is from the Pinzgauer Parts Manual. It's the original part number used by Steyr. Most common hardware pieces, (fasteners, seals, etc.) are no longer stocked by their original part numbers. The description of the item in the parts book is generally all you need to find it since they a...

The seal you are looking for is part number 900.4245. It is a copper seal ring (aka crush washer) 27mm od, 22mm id. It should be available at NAPA or most auto parts stores.

The inlet and outlet tubes are press fit and over time have been known to come loose. I learned from Thilo Kass to use JB Weld Kwik to secure them in place after a thorough cleaning and mild wire brushing. Use a toothpick or similar item to pick up a dollop of JB and spread it around the seam. Alter...

Very nicely done!

The price seems quite reasonable - GLWTS!

Perhaps this would do what you want?

I've got 8-10 of them but unfortunately I'm in Wisconsin and shipping is darn expensive. If you're near Texas I'd check with Andre at Fat Fabrications.
