I'm rebuilding a Allis HB112 GT. I've had it for the better part of two years just sitting in my garage. The whole time it sat it leaked out of the rear pintle. I understand this is somewhat of a common problem with the Vickers pumps. Anyway, I decided to finally finish up the rebuild and fix the leak. I contacted a supplier and got a quote for a re-bushed housing, replacement o-rings, and a new gasket. 


Total cost with shipping: $350 before a $75 core exchange refund.


My issue is this:


I broke down the pump and the housing has been "redesigned".

The housing has been machined out to allow for a needle bearing and oil seal at the pintle. This was done to both sides of the housing. When assembled the oil seal lip is very close to the edge of the o-ring grove, but it does stay clear.


I'm trying to decide which way to go. Does anyone see an issue with the this current build/design? I think the seal will hold and if they do wear out they are an easy replacement. 


Do I drop $275 (might be $350 due the core/original house being changed) and get a re-bushed housing and rebuild it as originally designed, or do I spend $15 and replace the two oil seals and hope it works?

Ditto!  Someone did a real nice job to repair that housing once already.  I would keep it and try the seals.  This is a nicer fix than the re-bushed housings!
