Where is JDemaris? CAV pump question

Ultradog MN · May 23, 2011

Someone run him off?
I haven't seen him lately.
I've been messing with a 3 cyl CAV rotary pump here.
I took the 4 bolts out of the back end of it and sprayed it out with brake cleaner. All the ports had been open and I was worried about having junk inside so I sprayed it all out with brake cleaner. I could see the offset vanes inside. Good thing I did as there was crud in there. Afterwards I shot some PB blaster in there to lubricate it and put the cover back on, put the 4 bolts back in and tightened it down.
I wonder if those 4 small bolts (5/16 head) should be torqued?
The seal there looked fine so I just put it back in. Ok?
I could ask a dozen questions about this pump if someone could tell me about them. Or, if I could find some literature about one I would do my own homework.
I'm over my head but not scared.
Suggestions and advice are welcome.
Thanks -

Not JDemaris, but I did some research before I decided to take mine to a shop for rebuild. Here is a link to a procedure from a different vehicle. I also have scans somewhere from a british taxi. I think I could have done the rebuild, but just kept running short of time and needed the tractor back.

My Ford Service manual also has a narrative. If you want I can scan it sometime later in the week and e-mail it over to you. Won"t be able to get to it until probably Friday.

Thanks Kirk. That is a real helpful link. I saved it.
Also thanks for the offer of the narrative.
Yes I would be interested in it if not too much trouble.
