Advice required for Howard 300 clutch Brake

[Veg Grower 0]

Hello

 

I aquired a Howard 300 a little time back and it had been taken apart and put back together again. It seems as if there are some missing parts. One of the missing parts seems to be the Clutch brake as when the clutch leave is presses the cone moves but the main drive wheel does not stop. I have read that you can get a brake disk for these howard 300's but I do not know where they should go. I have never had a howard before and this is my first Howard 300 which came with the old Kohler K91 engine which we removed and replaced with a honda engine whilst we slowly refurbished the K91 which is still work in progress

 

Any advice on where the brake disk would go with possibly a image or photo of the location whould be of HUGE help in getting the Howard 300 in full action again as it is only the clutch brake which is stopping me from using the machine.

 

Thanks all in advance.

 S1g is the man for Howards. Refurbished a few. Not on here much lately due to ill health, but send him a PM. Also look up his rebuild threads. May be something in those that can help you.

Thank you Stormin for the welcome and the advice.

 

I will look into what you have suggested.

I did hope that a Howard expert would come to your rescue. I’ve never owned a 300/350 but have worked on a few. A while back there was a clutch thread on another forum

https://www.vhgmc.co.uk/forums/topic/howard-300-rotovator/

But I’m not sure that there is anything useful there for you.

I will scan and post an image of the cone clutch set up with a brake. Having worked on a few over the years and being kind I would call the brake a bit of a lash up . Unless someone tells me that I’ve been doing it all incorrectly it seems a very fine line between disengaging the clutch and the application of the brake on the driven ( female) cone - needing frequent adjustment. It is also important that the thrust bearing is in good condition and not partially seized.

Thank you Wristpin. It is appreciated. I have both that exploded diagram and I have the forum post you mentioned on my bookmarks from previous searches on google. I have been researching this for a few months now and keep coming up with a blank. I have seen plenty on the Howard 350 but hardly anything constructive to do with the Howard 300 clutch system. Following further invistigations yesterday I sent of an email to http://www.howardregister.com but I have not yet had a reply.

 

Again thank you for your post wristpin it is most appreciated. I will keep you all updated with my progress which might be a little slow as it depends on the weather.

 

Edit: I forgot to add that whilst I was doing further research yesterday I read that the Howard 300 used a fibre thrust washer on the clutch so I did a little searching and found a picture of said fibre thrust washer on google images. The image lead me to a ebay listing so I contacted the Ebay seller and asked them if they will be having any in stock and where the thrust washer was situated. He replied saying that they will be some in stock maybe later this week and he included a picture of the item and the location of the fitting which raised another question. In the image there is a "Lollypop" looking item which is also missing from our clutch setup on the Howard 300. So I have sent him a reply questioning what that lollypop looking item is and if he has those in stock also. I will include an image bellow.

I was aware of that disc but I didn’t mention it as I thought that it was an early version that was superseded by the one on the arm. I believe that the  lollipop was to act as a pressure plate to Sandwich the friction plate between itself and the pulley. The “stick” stopped it rotating. I’ve got several 300/350 manuals and parts lists but none of them show the lollipop nor the friction disc.
