Bulletin Summary
Service Information Letter 744 notified customers that the mounting hole for the return filter on the hydraulic reservoir was produced over-sized on the affected units. This can cause the O-ring between the return filter head and the reservoir to not seal properly which can result in potential water intrusion. Altec has designed an adapter plate and gasket to provide the correct hole diameter for the proper sealing of the O-ring. Order the Return Filter Seal and Plate Kit, part number 990875329, by calling 1-877-GO ALTEC (1-877-462-5832). Altec suggests that the kit be installed no later than the next regular maintenance interval or 90 days from the receipt of this SIL, whichever comes first. This repair
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
