Rebuilding oil pump
 

just got my oil pump rebuild kit, from Bert's install the bushing then install the new shaft and idle gear only to find out it locks up turning hard turn the idle gear both ways still hard to turn, by it self each gear turns easy when install together there is binding anyone had this happen to them AL

Re: Rebuilding oil pump
 

Did you ream the bushings or burnish them in after installation?
I'm wondering if the ends didn't get a bit deformed while installing them.

On second though I see where you say they turn easily by themselves. Do they turn hard with the bottom plate installed or also with it not installed?

Thanks tom for the reply yes the bushing are smooth the shaft by itself turn easy very nice its when you add the idle gear that there is a issue

Thanks for the reply and yes I use reamers before thanks for asking, It seems to me that it is a meshing problem the shaft itself with the gear on it is very smooth turns easy there is no slop in the brass bushing and the shaft, if you take this shaft out then just install the idle gear it also very smooth no drag, if you install both of them this is were you get the drag i did not have to ream the bushing the shaft went right in. Does the main shaft need to have play thanks Allen

If it just bindsup in 1 or 2 spots look for dings and burrs on the gear teeth ---mark the teeth that bind together and look close

Re: Rebuilding oil pump
 

Are these new gears or the old ones. If new, do you have the old ones to try??

OK got up this morning went and install the old idle gear with the new shaft perfect smooth as glass, install new one blinds up got to be in the new gears,

Re: Rebuilding oil pump
 

I have run into this problem with the cheaper rebuild kits. Never with the melling. You just have to put something on the gear to find the high spots and file them off. I have used prussion blue and just magic marker.

Your Right John, Melling is the only kit to use, they made kits for the Model A when they were new. The Repro kit does not fit, and the one I had, had chatter markes on the gears, and the bushing were oilight, I Think? very poor! Herm.
P.S. Melling Kit No. K-18

Re: Rebuilding oil pump
 

Did you try turning one gear over?

Re: Rebuilding oil pump
 

Thought this too test see what happens.

Re: Rebuilding oil pump
 

yes Clem every which way as i said you can install the old idle gear and it works fine, called Bert's and He said he will refund, where do you get melling who has it

Re: Rebuilding oil pump
 

I looked up the melling site and I find a price on the kit or how to order one. Anyone have an idea?

I found one dealer - Northern Auto Parts

http://www.northernautoparts.com/Pro...ntoryId=440431

This address should take you to the kit they sell

Note - I looked on the NAPA & Carquest web sites and they did not carry the oil pump kit amoung their on-line listing. It may be worth while to call your local car parts store and check.
