Product: Bambi Bucket
Models: Bambi Max
Subject: Bambi Max Guide Rod & Bolt Changed

Background:

This bulletin is an update of a bulletin previously issued on September 16, 2015.  SEI has been made aware of two incidences of guide rods failing on 25” Bambi Max valves.  In both cases, the failure occurred at the interface between the guide rod and the sheave bar.  Both failures are considered to be the result of impact but the exact details are still unknown.

IVC Cable Installation

Jun 1 2015
Product: Bambi Bucket
Models: Bambi Max
Subject: IVC cable installation

Background:

Older Bambi Max manuals instruct operators to fasten the IVC power cable to the IDS hub and deployment cable using zip‐ties. Operators are instructed to provide some slack during installation. Despite this, SEI has observed incidences of the power cable being pulled from the strain relief on the IVC, resulting in water ingress. The zip‐tie may gradually work along the power cable over time and eliminate slack.

New Sacksafoam Controller

Feb 19 2015
Product: Bambi Bucket
Models: Sacksafoam I
Subject: New Sacksafoam Controller
Reference: 
The new Sacksafoam I manual will be released soon.
 

Details:

SEI is introducing a new Sacksafoam Controller (SFC). This SFC will supersede the original controller for customers with bladder style Sacksafoam I systems. Currently, the new SFC is not directly compatible with Sacksafoam II or Sacksafoam III systems. SEI will continue to provide the original controller to service Sacksafoam II’s and Sacksafoam III’s while stock exists.
The SFC is operated with a glove compatible touch screen. The SFC includes an adapter that connects to the existing Sacksafoam wiring harness and includes a D-sub connector that can be used to connect with a remote injection switch. See Figure 2 for details.
 
DZUS rail adapters are available for the SFC. Please note that the product dimensions have changed and the new SFC will not fit in the same location on a DZUS rail system as the original Sacksafoam controller.

Product: Bambi Bucket

Actuator Cable Guard

Aug 20 2014
Product: Bambi Bucket
Models: BBX4453, BBX5566, BBX6578, BBX7590
Subject: Actuator Cable Guard
Reference:  DC2014.09

Background:

There have been multiple failures of Bambi MAX IVC’s and actuators on the 25” valve. Investigation into the failures has identified the problem as damage to the electrical cable at the point it enters into the actuator. Water then enters the cable and migrates into the actuator and IVC causing a failure. The damage to the electrical cable is being caused by the IDS restrainer cable during deployment. In one case, the cable gland was torn off.

Purse String and Valve Update

Jan 17 2014
Product: Bambi Bucket
Models: Standard Bambi Buckets
Subject: Purse String and Valve Update

Details:

Most customers find that changing purse strings is a frustrating exercise and can be an expensive one if it is required to get a bucket flying. To reduce the frequency of purse string replacement on a bucket, SEI has decided to increase the size of the purse strings on medium and small valve buckets and to change the stainless steel grommets used on all the valves to lower friction brass grommets.
 
Small buckets (6072-1821) using #4 nylon cord will now use #5 nylon cord and similarly medium buckets (2024-3542) using #5 nylon cord will now use #6 nylon cord. The purse strings on the large buckets will not be affected by this change, but the grommets will be changed on all valves.

New Seal Kit for 16" Valve Actuators

Jan 13 2014
Product: Bambi Bucket - Bambi Max
Models: Bambi Max 16” Valves
Subject: New Seal Kit for 16" Valve Actuators
Reference: Bambi MAX Service Manual (1518-3542) version B

Background:

There have been several occurrences of valve failures due to water ingress on the motor assembly
housing. The cause of this problem has been determined to be caused by faulty gaskets.
 
The original motor gaskets were made by hand. When SEI went into production, it switched to a gasket
which was punched on a machine. The holes for the bolts were subsequently made oversized due to the
punch design. During installation, if the gasket was misaligned, the water could get through the bolt
holes and into the motor chamber.
 

Solution:

  1. The motor gasket now features smaller holes punched by hand. This prevents any water from getting through the holes in the gasket.
  2. The screws which secure the motor cover now have a built‐in sealing ring for additional protection against water ingress.
SEI is providing customers with the affected valves upgrade kits (part number 010755) containing the
new bolts and gaskets. These can be easily installed by the customer.

Suspension line link connectors

Jul 30 2013
Product: Bambi Bucket
Models: BB5566 - HL9800, BBT5566 ‐ BBTHL9800
Subject: Suspension line link connectors
Reference: Bambi Bucket (5566 - HL9800 Models) Service Manual (p. 46)

Background:

New suspension lines for 5566 buckets and larger will come with link connectors to allow for easy
replacement of single suspension lines and pairs without replacing an entire half‐set. The change also
reduces the likelihood of the thimbles jamming on the lower control head shackles.
 
The new links allow customers to quickly replace a line with the same hammer and punch already
required to remove the lower links. Replacement instructions can be found in the 5566‐HL9800 manual.
 
Customers without the new suspension lines will likely need to purchase a new half‐set if they have a
line fail, but subsequent failures may be resolved by purchasing a single line or pair.
All updated suspension lines for 5566 and larger buckets are 3 inches shorter to accommodate the link.
 

Recommendations:

If a suspension line on your Bambi Bucket is damaged or fails, it must be replaced. A suspension line
displaying any noticeable kinking or fraying should be replaced. If your suspension lines are new models
with links included, you should replace the damaged line individually. Individual lines come in singles
and pairs depending on their position on the bucket. If your suspension lines have not been updated
with links, replacement lines should still be ordered as a half‐set. Refer to Figure 1 and Figure 2 for clarification.

Figure 2 - New Style with Connecting Links (Order Single or Pair)
