The last models in the later years of production, that had the plastic belt cover instead of the steel cover didn't use 6:1 reduction Briggs engines, they had standard non reduction engines. So those can be repowered with pretty much anything.When you repowered with Tecumseh how did you handle the six to one reduction? Are there options ?

I also had the advantage of working at a small engine shop at the time that was a Bob Cat dealer in the 70's. It was nice that they had donor machines in the back and the older mechanics had all kinds of insight on the machines that came in for service. I purchased the Bob Cat 520 I currently own as scrap from the shop since it came in with a blown Briggs engine as a trade, and I bought the Tecumseh for it from the shop at a small discount.
6:1 reduction engines are available but start about $300 vs the $100 for a Predator.
I've been to National Ace many times. I worked for Ma Journal before retiring in 2013, so it was just up the street for me. I remember finding an old dial indicator there for cheap once. Just stumbled across it while looking for something else.I used to work at National Ace Hardware in downtown Milwaukee that is where I got my Bob Cat parts, they were a dealer in the 70's so they had a stash of parts and some used parts units at the time.
Welcome to the forum.New poster here. Gotta say I love all the BobcaT enthusiasm on this forum!
I just picked up a 7-horse yesterday, an earlier model with 2-speed transmission. It's my second -- I inherited a latter-model 5-horse 20 years ago from my uncle that's still going strong. It has the plastic belt covers and 3-speed/reverse drive.
A year or so after the 520 came into my possession I had to replace the impeller bearings. I hunted high and low for a parts source (this was pre-World Wide Web) and finally by a phone call across the country I was directed to the small-engine shop half a block from Uncle's home in West Allis, Wis. (J.H. Medinger -- does the name ring a bell, SJ701?)
I stepped up to the battered parts counter after waiting in line for about 20 minutes and told the counterman what I needed. He went into the back and returned with three dusty plastic bags holding spherical bearings -- all that remained of his stock. I bought all three.
Last year I did another chassis overhaul and replaced a couple sprockets and a chain in addition to the impeller and auger bearings. The bearings I needed came from Triangle Manufacturing in Oshkosh. The sprockets I got from eBay, and the roller chain from a Farm & Fleet store. All off-the-shelf stuff.
I'll have to post some pics of my machines after I get my post count up a bit.
Welcome to the forum.Hi sj701
I was reading all the posts here and love the fact that you guys are keeping the Bobcat legacy alive. I noticed that you were looking for an 8hp 28 inch
bobcat for your collection. I actually picked one up last year from the original owner and it is complete, even with manuals. I'm not sure how to upload pics here but if you want a pic of it I can send it to you.
