    Replacement engine for BCS 948 tractor/tiller.

    Thank you. I was wondering if I needed to take apart the clutch cable and lever (I need to at some point to replace the rubber boot), and your post lets me know I don't have to do that at this time. Edit. After initially posting this, I went out and got the engine and clutch off of the tractor...

    Replacement engine for BCS 948 tractor/tiller.

    Yes. The 948 that I have came with the 34-in tiller box bolted to a 3-bolt 3-in extension. I took the top center stud off of the extension and added the quick hitch. I have a 30-in tiller that I use with the quick hitch. The extra 3 inches of extension make the balance a bit better for other...

    Replacement engine for BCS 948 tractor/tiller.

    In regards to replacing the engine, is it as simple as removing the 4 bolts to the clutch housing and pulling the engine off, or is there a bolt/screw that secured the clutch to the engine shaft?

    Replacement engine for BCS 948 tractor/tiller.

    The 948 has built in (add-on) weights that are on the engine side of the axle. I found that the balance on my tractor made it almost unusable for anything other than the 34in tiller box, so I took the weights off and had the tires foamed. The balance is much better now.

    No spark

    After posting above, I found a spec sheet for the gx390 engine, and the 0.40mm piece of milk jug should have been good, as the spec is for 0.40mm or 0.17in.

    No spark

    I finally got it started again, but I'm back where I started as it runs great when cold and runs for about 5 minutes before bogging down. I definitely had the air gap too wide, as I'd used a piece of milk jug at the suggestion of a YouTube video. It measured 0.40mm. I subsequently used some card...

    No spark

    I actually added a bit of seafoam to the gas and oil. I still haven't gotten my garden tilled. I put the finishing mower with grass catcher on it first, to feed some lawn clippings to my goats. It ran good for about 5 minutes, then bogged down. After cooling, it was a repeat of the same. I...

    No spark

    Last fall, I went to use my 948 after it had been unused for a couple of weeks, and found that I couldn't get it to turn over. I took out the spark plug, and it turned over without any trouble, which told me that the exhaust valve was stuck closed. After covid in the fall of 2020, I haven't had...

    BCS Snowblower

    I use filled tires on my BCS for everything. I got tired of having to buy new tubes every time I had a flat. Because the stiff sidewall, I wasn't always aware that I had a flat, until the wheel spun inside the tire and sheered off the valve stem. After the third flat, I had the tires foamed. The...

    Replacement engine for BCS 948 tractor/tiller.

    I did add an electric start to mine, but I had the balance issues even after I added the electric start. It is so nice to not have to pull start that engine.

    Replacement engine for BCS 948 tractor/tiller.

    I have a 948, and its balance tends toward the engine side. I have had to rig weights on my snow thrower, and the 45" oil bath sickle mower is a bit light in the front, though not unusable. Putting a heavier engine on is going to throw that balance off even further. I'd rebuild the GX390. The...

    BCS - Can't change directions

    Thank you. That solved the problem. I did have to move the cable clamp pin as there wasn't enough movement at the lever.

    BCS - Can't change directions

    Thank you. It's been raining here, so I haven't played with it, yet, but when the lever is thrown, it's about 2cm from the end stop. I'll tighten it to get it closer to the end stop. So, I think that might solve it. If it's something internal, the one consolation is that I'm already going to...

    BCS - Can't change directions

    It doesn't matter which directions the handle bars are facing. The lever at the handlebars moves the lever along the side of the transmission, but it will only drive in one direction. It's acts like it's in neutral when in the pulled back position (away from the engine). It moves appropriately...

    BCS - Can't change directions

    With the handlebars oriented on the pto side of the transmission, my 948 won't go into reverse. The lever easily moves into the forward position, and engages. It is difficult to throw the lever back into reverse. (The converse is also the same. When using a front facing implement, it won't go...

    How Much Does Quality Cost? Looking at the BCS System

    I heartily agree with plumberroy in regards to the Troy-Bilt. I had a 1974 or 75 model Horse with Tecumseh engine with electric start that I inherited from my dad. The tine speed was barely faster than the wheel speed. It always started, but to get things tilled took at least a half dozen...

    Considering new BCS

    I had a mid-1970s Troy-bilt Horse powered by the 6hp Tecumseh engine, and I thought it was next to worthless. It always ran fine, but the tine rotation speed was only about 1.5 times the wheel speed (Troy-bilt did increase the tine speed a couple of years later). The tines almost walked along...

    Battery size for 853/948

    The parts manual for the BCS 853 only shows a 14-16ah battery. Does anyone have a brand and part# that they use? The 948 doesn't show anything regarding electric start, but the battery/tool tray and 0lastic cover are the same part numbers. Thank you.

    EZ oil drain valve or Fumoto drain valve on BCS???

    Has anyone used a Fumoto or EZ oil drain valve on a BCS tractor? I'd like to add an EZ or Fumoto drain valve on my BCS tractor (948) to make changing the oil a bit cleaner as well as easier. The guard bar sits close to the drain plug. Will one of these fit in the available space? Thanks.

    EZ drain valve for Deere 430

    I'm wanting to replace the drain plug on my Deere 430 garden tractor with an EZ drain valve. Does anyone know the size and thread pitch? It's time for an oil change, so now's a good time to do a replacement. Thanks.

    GX390 Flywheel Nut Question

    I recently purchased an electric start conversion kit for the GX390 engine on my BCS 948. My shoulders are complaining about the amount of torque that they have to pull against to get it started. I don't have a socket head that fits the flywheel nut. Does anyone know what size it is? I tried to...

    BCS blues

    Success! I finally got the PTO shaft out of its socket. I was giving it a few wacks with a hammer, per the instructions from EarthTools download, and not getting anywhere, so I looked at tools that I had purchased when working on the front end of my pickup. The pictured tool with the cut out...

    DIY BCS snow blower weights

    I understand your pain. I added extensions to my 948 (that has standard front weights that are a pia to remove), ultimately adding 2 3in extenstions plus 2 quick couplers (one extension had both the male & female quick couplers so that it could be easily added and removed). It had barely reached...

    430 with stuck brakes

    My wife was using my 430 and slammed on the brakes, which resulted in the brakes jamming. The throddle will not move forward at all, but will move slightly in reverse. The parking brake lock is in the unlocked position, but will not move, either. Where might the jam be located? I'd just as soon...

    60 Mower 400 -- How to repair deck for 430

    Can this deck be salvaged? If so, how would you go about doing it? It looks like a major welding problem. I was looking at a pdf regarding a repair with using POR-15 and fiberglass (http://www.por15.com/CustPhotos/FloorFixStory.pdf) and was wondering if that might be a solution. Thanks.

    Deere 430 - Where does the tube from the fuel tank go?

    There is a tube off of an elbow on the fuel tank neck of the 430 tractor. Does the other end connect somewhere, or does it just dive under the deck to vent the tank? I have the fender deck off of my tractor at the moment, and I found a short piece of rotted hose laying on top of the tank, but it...
