Title: Jonsered 2077
Post by: KilliansRedLeo on August 14, 2013, 09:30:03 am
Got a pretty nice 2077 in on trade for another saw. Looks like a pretty nice saw, a bit heavy but it is a 75cc saw after all.

I am trying to decide if I clean it up and flip it or try some mods on it.

If anyone has any ideas on what I might be able to do with it in terms of mods, let me know. I don't even know how well this particular saw responds to modification.

I have run one of these saws in the Poulan Pro version and they are a strong running saw.

JMO but stock for stock I would almost bet my 70.7cc quad port 445 poulan will stay with or out cut the poulan 475 76.5cc = jred 2077 single transfer style.  I have both and the 475 has a hair more intake duration that helped it out.

How old is it?  The early ones didn't have the fully deveroped "Air injection"/"Turbo"/CCS (nor did the PP475, or the early P7700s).

The guy who I get the saw from came in today with a gift, BIN OEM cylinder and piston for the 2077! So now does anyone know if this will work on any other saws?

A stash of NOS hit the market http://www.ebay.com/itm/Jonsered-Poulan-Partner-Cylinder-Kit-NOS-2077-2083-425-pp475-505-/290971314882?pt=LH_DefaultDomain_0&hash=item43bf3deac2

2077 will fit all the rest of the series too.

The P710/PP445 is a later model, so it wouldn't be that much of a surprice if it is at least close.

Seen this in a group of saws, trimmers and mower for sale as a lot.

The metal clutch cover was a added bonus.

 Some redneck stuff happened over years. Pulled top cover, air injection tube wrapped in that heat foil stuff. The chain brake left side they used a big bolt and wore hole through case on side. SMH. Get pics in a bit.
7700 pulled muffler piston has small scuff streak in very center. Pulled clutch drum, the better clutch put has the metal worm gear.
8000 might be locked up.

Just tore it down.  Parts saw it is. Cylinder can be saved easy. Piston I could use even.  But crank got moisture and flywheel had sheared a keyway at one time.

Metal clutch cover even had the outer metal plate.  So will make a good one for someone.

Wait till you see some of these redneck fixes that failed.


Pics later.

That saw was sure dirty.   Like the worm gear puller.

What method do you use for removing the flywheel?

First just knock center of crank. Then if not loose. Penetrating spray and then knock.  Most times first few try comes loose.

These parts are pending $ next week.

Metal clutch cover cleaned up nice.

Since guy is a collector I pulled him out a nice muffler then one that came off 2077.  77 one was rusty looking
