nUR prizewinner this week is a Hastings reader, Mr. D. G. Luck. He tells me that the company he works for operates a number of Dodge D307 short-wheelbase tippers which are used mainly on site work or for sand and ballast running. After very short mileages all of these have had Hydrovac failure. The reason for this, says Mr. Luck, is that sand and dirt go into the filter and the piston chamber-consequently lifting the piston seal enough to allow the vacuum to he exhausted
whilst the footbrake is applied. Although this would be unlikely to happen on normal road use, it is very troublesome in the conditions in which these vehicles arc actually working.
The following modifications have now been made. The hole in a large repair washer has been enlarged and into it has been brazed a fin. inside diameter copper pipe and fitted into the air filter body with the existing circlip: A small, reinforced hose was fitted between the Hydrovac and the chassis to the underside of the cabin. After fitting the reinforced hose to allow for cab movement the pipe was continued through the cab:n floor and up under the nearside seat, where a filter of the type used on older Hydrovacs was fitted. As a result the Hydrovac now breathes comparatively clean air from inside the cabin and has cured a very annoying cause of trouble.
Comments Handyman: This is a firstclass remedy—and one I would -tot hesitate to adopt.
