jabsco impeller puller

i want to buy a jabsco impeller puller but am a bit confused as to which size i should get (and since i'm restricted to ordering over the internet i can't do a fit up trial).

the depco pump company has a pdf which says the jabsco puller model 50070-0040 is suitable for impellers up to 2 9/16in.

other sites say that this puller is only good for impellers up to 2 1/2in.

my impeller diameter is 2 9/16in

can anyone confirm which is correct.

regards

According to Jabsco, the Impeller Removal Tool 50070-0040 is suitable for 40 - 65mm (1 9/16" - 2 9/16").

The confusion comes from converting from millimeters to inches.

Of course, since 65 mm is only equal to 2.559055118113", whereas 2-9/16" = 2.5625"; it will depend upon which is the 'hard' measure (mm or inches), and which the 'soft' approximate conversion. Given the metric (65mm) measure is given first, I expect that 65 mm (2.559") could be the maximum diameter, and you might be better off with the larger puller (#50070-0200)

Before purchasing, Id query ITT-Jabsco at:

what engine do you have?
an impeller with a 2 9/16" hub I would expect on an 8L or 9L Cat or such.
Are you measuring the OD of the vanes or the OD of the hub?

n m: i have a Yanmar 4LH-HTE.

the best info i could find was here www.depcopump.com/catalog107/141.pdf

my understanding was that the impellor was sized on its OD (i.e. vane diameter).

have asked jabsco via their tech support page but no response as yet

grateful for any help i can get.

I have 10's of thousands of $$$ worth of tools but for the past 30 years I have depended on a trusty pair of channel locks or a couple long skinny screwdrivers prying it out from opposite sides.

or two screw drivers and wedge it out.
Impeller pullers need to bite into the hub or meat of the impeller. If you grab a vane it will rip off.
I believe the tool your looking at will be applicable. I need to preface this with I haven't had an LH apart in 2 years.

Those impeller pullers work pretty good. I filed the points on the arms for a better bite......and replaced the tightening thumbscrews with bolts....
