PB 070 Resto

Alpine

New project

PB 070 DR
Vintage Pistenbully. I was looking for a private alpine excursion / ski machine that could be used in backcountry and have some advantages of a hydro machine without being massive. The little 70 comes in at what i consider a healthy balance between weight , power, and size between Thiokols and Bigger groomers. This one has 3500 hours, and runs well.
I will begin some restoration in the spring when the snow goes away. Although we are almost there now.
70 Basic Specs...8 feet wide tracks, 5000 lbs give or take without tiller system but with box when i finish it. Blade etc. Little Mercedes diesel, is excellent on fuel consumption, and all hydro components are in good order, although i will do a complete flush here pretty soon, with new fluids filters etc around. Tracks are the wide version, which is pretty cool, for getting into the big stuff up higher, and it maneuvers well. They have a few outside splices, i will do a little work on them, thinking of building a set of summer tracks for it.

Updating electrical system in terms of relocating batteries from cab to rear, more room for jump seat, and i have added some upgraded fuse systems. I have no problems with glow plugs etc, but may upgrade to a newer style. build a dual battery system for it, which will be completed when the passenger box gets finished and wired up.

Needs some love cosmetically on the blade and a little welding, some paint etc.

These PB's Came with heated mirrors, heated windshield, etc etc. Rear window is cracked, but better than the front. will replace glass in it. Replaced the exhaust pipe with a new one which will extend beyond the passenger cab.

Fun Fun, too bad winters almost up, but next year it will be ready for it.

I looked up the 070 and it uses the MB OM616. That's a great 4 cyl engine, if properly maintained it could run many more 1000's of hours.

Yes, I totally missed the replies here. OM 616 indeed. Have her in shop now for the summer going through her. Torques, and filters and lubes. She is an 1987 i believe.

Can Anyone find a north American modern match or two for options on paint? I would like to do some work on the cab, and paint the Box I have built for this cat to match this original color. Factory calls it: BASF Acrylic Laquer # GAT‐3446

I am sure that some Body shop or collision repair person can cross reference the paint code.
I have had good luck by taking a non-sun faded part to a paint store and having the paint scanned.

Silly question:
are the seats in the factory location?
is the motor mounted kind of far back?

Good Observation on the seats. The driver seat is in factory location.
The passenger seat I moved back for leg room. Behind it was the factory battery location, which I relocated as I wired it for dual batteries and in return gained 10-12 inches for the passenger seat to slide back and mount. The engine is mounted right where it should be, Mid center, behind the cab.

For sale at this point, I love it, but I may need to be away from it during prime season. If it sells good. If it does not and i can use it this season great.

Replaced rear window gasket and used lexan. This way a slider can be added for possible contact with the box. Shedding weight, I keep telling myself. The gasket was expensive. I choked a little when time to pay. Was as much as the lexan! Making progress. The side door panels removed, along with the stinky old foam insulation. Replaced with windows, which open up the view and cab dramatically. I kept the original 070 striped aluminum panels. They can be swapped back in. Excited to clean the interior and add some finish. Stereo, and Multi-View cameras/monitor install coming eventually.

Back to the grind...Block Heater Removal

Some additional pictures, new Block Heater for the Mercedes. Really a simple thing, but so important. Cleaned up the Manifold/s and did some work around the engine. New gaskets and seals. Has had a good good coolant flush.

Some work that needed to be done....wiring demons. I decided to stop ignoring them and tear out the wire harness and find the problems. In the end, the problems were minor, but some upgrades and repair was required. Replaced some primary fuse systems and set up options for aux power. Most of the time was spent translating German Wire code, and then tracing Wires, and pulling apart the Wire Harness. Upgraded some wiring as well. Replaced bulbs and got little things like high and low beam switches working again. Everything electrically, and I mean everything is electrically functioning....Headliner shot for you Red130.

Looking good. I suspect my headliner is not stock. It was made from some sound absorbant foam, but it's getting a little ratty.

Some new belts for the 70. replaced a few and put the tracks back on her since the spring. Took her for a quick run. Few things left to do, but she has new battery, New Juice filter, and Hydraulic Juice. As per recommendations from Pistenbully, I am using good Ol', ATF. Wiring in Stereo and have mounted the blade back on. I didnt bother welding up the dings in it, as it is more than structurally sound and gave it s a quick dose of Green on the wings as to hopefully deter me and others from making contact with trees etc. I am starting to aim my direction at the box, and maybe make some progress.

Snow Snow Snow....
