appreciate it, and I personally don't care what others think. im a 27yo electrical engineer with a decade or more of experience in general construction and the machinist trade. combine that with being an insomniac and a girlfriend who works nights, and you end up with a mind that dosent shut off and a whole lot of free time. its also very helpful when your dad, who is a retired machinist gets bored and puts in a shop at the house haha. I enjoy the projects where people say it cant be done or its not worth it. the way I see it. its not costing me much, im learning a lot, and ill have a nice toy to call my own.
My apology…..I answered your serial number question on the other thread before reading this one and seeing that you had already contacted bobcat for the info. Keep at it.
There is no need to pull the motor to time it. there are timing marks on the flywheel/fan. On the back right side of the machine there is a vent that goes to the cooling fan / flywheel. There is a round screen on it, pull the screen off, I think 4 screws. There are two timing marks one for VH4D and one for the VF4D. put a regular old timing light on it, adjust the timing until the marks line up. Pretty simple to do really. Just make sure which engine you have, as the timing is different between the two. The 600 should have came with a VF4D but many were converted to the higher hp VH4D.
I do have the vh4d, or so I would believe the sheet metal on the motor. Looking through the side vent, once I take the screen off. What am I living the timing mark on the fan up to? I'm used to a degree I dictator or something... I'll head out to the shop in a few to check that one out
Take the screen off the flywheel shroud. Find one cooling fin that is marked/stamped with an 'X' (It is in line with the 'DC' cast on the face of the flywheel). Mark that fin with white or light yellow paint. Cylinder #1 is the closest one to the flywheel on the left side (viewing the flywheel). There is a small hole on the shroud at 23 degrees BTDC. Use a timing light and make sure the engine is running at least 2000 RPM; the fin you marked should be in line with the hole.
So I found and marked the x but where is this mythical hole you speak of? Possible to get a reference pic?
Thanks for the photos……this is an interesting machine for several reasons to me. First it is only the second M-600 that I've seen that does not have the corner braces (for attachments) yet it has a '68 manufacture date, while the other '68 M-600s I've got in my data base all have the braces. Secondly…it has the front hooks (for attachments), making this the first machine I've seen that has the front but not the rear capabilities. Sometime in '68 they switched the back support to a design that has a strap connecting the two uprights and stayed with that design until they stopped making the M-610 in 1982, yours does not have that feature. I know you've said before but where are you located? I've got all sorts of parts I could help you with. Also…….the timing mark……It depends on where the sheet metal came from. I've seen it a number of different ways…….sometimes the flywheel screen is bolted to the shroud and will have a notch in the screen frame, sometimes the flywheel screen is bolted to the flywheel itself and the timing mark will be a notch or as Mark mentioned, a hole in the shroud. Most of the time there will be two marks (one for VF4D and one for VH4D) and as you look at the flywheel they will be at roughly the 10:00 o'clock position.
Also…..I mix and match the sheet metal all the time……right now I have one machine that has no timing mark at all. I time it using the "by guess and by golly" method. Not good but it has run for many years that way.
So, I'm from the taunton Massachusetts area. And I found the two timing marks. They are small notches indented into the sheet metalI'll toss up some pics adyer .
Yep…..hard for me to help you that far away.
No worries. I've rebuilt cations truck and car motors. This little guy can't be to difficult. The only thing I have yet to figure out, maybe you can shed some light on it. The governor, is it supposed to be spring loaded one one direction or the other?
Also, any information you can send my way about this machine I would appreciate it. And what types of attachments the front hooks are for?
Here is a online V4HD service manual. It might be able to help you out and answer a few questions for you. Also, as a side note, you can trust 6bnorna, and Tazza, skidrow and a couple others. Those guys give accurate trustworthy info, I never mind being corrected by those guys. They are not key board know it all's and always help. Here is the web address for the manual, sorry I don't know how to make it a hyperlink so you most likely will need to copy and paste to get to it. http://www.wincogen.com/files/downloads/winco_engine_maintenance/wisc_vh4d_repair_manual.pdf
Forklift mast, backhoe, broom sweeper, snowblower, sickle mower……there were several other attachments but I'm not sure which used the hooks and which only the boom arms. There was a cotton bale clamp, post driver, tree digger and vacuum sweep that I believe used only the arms. Probably more.
I meant help with parts……..I don't have time to turn a wrench for someone else. Yes the governor has a spring……..careful that the VF4D and the VH4D have a different adjustment on them so your M-600 manual will not show the VH4D adjustment as it came original with the VF4D.
Oh, yeah. The only help I'll be needing is knowledge. I'm no stranger to fabrication and mechanic work. I may be an engineer but my second home is my garage haha
I'll have to pull the governor off tomorrow and see if the spring broke. The arm just kinda floats in the wind..
a few more photos to bring it up to date.
