Stihl 075 - Complete Rebuild, Performance Mods

[bulletpruf]

Love the old 1111 series saws. I guess that's why I have 7 of them in various states of assembly and repair, along with boxes of spare parts.

I really don't have much need for one, either, since I don't mill, don't heat with wood, and don't have any large trees on my property that need to be dropped. Having said that, I still can't pass one up when I find it at a reasonable price.

I recently picked one up from a member here, SN 8295359 (should be June 1974, give or take a month). It's complete, and as advertised, it has had some case damage. I have a few clean cases in the garage, so I figured I would take the bits off the 075 and install them on a nice clean case. I'll split the clean case to install new crank seals and give it a good inspection, too.

I plan to do some basic performance mods; figured I would advance the ignition timing a bit, maybe mod the muffler (anyone done this to an 075?), check squish and maybe go with a base gasket delete, and maybe do some basic porting (anyone have any tips?). When it's all back together, I'll tune it, test it, and send it down the road before I start on my next one.

These saws seem to be in no-man's land right now. I suspect no one uses them commercially unless it's a backup saw to an MS880 or something like that. Some folks like them for milling, and they're a good saw for that. They're not quite collectible yet, but collectors are starting to catch on, I think. You can still find project saws for reasonable prices, but nice ones bring decent money...EDIT - HOLY *s-wordE, a reasonably nice 076 Super just brought $1525 on eBay!!!! https://www.ebay.com/itm/STIHL-076A...=true&nordt=true&rt=nc&_trksid=p2047675.l2557

Anyway, follow along if you'd like. I'll post details and pics as I progress.

All oem orginal is more €€€ than ported.
Ebay one is expensive, half of that Price i find them in better condition.

 

[bulletpruf]

Its more $ for a clean orginal than a moded/ported one.

Good point. If that's the case, I'll keep mods to a minimum.

Yes. eBay is great for sellers. Not always very good for buyers.

Here's what I have now.



Had a frolic and detour with some Jonsereds -- 80's, 90's, and 110's -- and out of town today, so I'll get back after it tomorrow.

Question, what's the plunger looking thing on the top of the case down towards the oil reservoir?

Eject button.

Eject button.

Another dumb question, what does it eject.. LOL. I have no experience with older saws

It ejects the guy holding on to the saw. It's a safety device that was used before chain brakes were available.

@Cooper264 - sorry, couldn't resist. It's the manual oiler. You use it when the automatic oiler isn't putting out enough oil. Helpful when running long bars.

Well hell I was expecting like a bar ejector or something funky. I like the older saws that have these "booster" type secondary oilers. Raises the question of if it would be worth getting like an older 084 instead of a newer 880 just for that extra oiling ability

Yes and no. The parts for that pump are tough to find. A rebuild kit might be available soon.
If your prepared to hunt for parts for years buy one. Be prepared to pay more or as much as new dealer parts for 880s.

Thats not very fun. Might be better off paying someone to hold a lube bottle over the bar

Only if you trade in one of those Wild Thang saws...

Great for milling then. Just get one that runs or you'll wish you did. Beat and broke old ones still haul chip.

I like the 075 076 series. I had a nice 076 super I sold on here. Regretted it ever since

Yeah, I have a nice 076 Supah with a brake (076AVSEQ?) and another one that had a trashed case. Will use the bits on a spare case that I have.

The one I regret selling was a minty 075. Sold it a few months ago. Pics below.

Thats a perty girl right there

Yep, I like them bad boys too, I currently have 2 075's, 2 076 supers and a regular 076.
Have had others that i sold. One thing i know is they can vary meaning one might be a
great runner and the next a turd. Have had a couple that would vibrate themselves out
the door while others are pretty smooth. they are cool saws a great big wood and milling
saws. Not fast like the 084, 088, ms880 but still a great torque monster at 111cc's.

Good luck Scott on your build.
